USAGE AND SAFETY PRECAUTIONS

In this manual, symbols are used to highlight warnings and cautions for you to read so that accidents can be prevented. The meanings of these symbols are as follows:

This symbol indicates explanations about extremely dangerous matters. If users ignore this symbol and handle the device the wrong way, serious injury or death could result.

This symbol indicates explanations about dangerous matters. If users ignore this symbol and handle the device the wrong way, bodily injury and damage to the equipment could result.

Please observe the following safety tips and precautions to ensure hazard-free use of the GFX-8.

Power requirements

• The GFX-8 is powered by the supplied AC adapter.
• To prevent malfunction and safety hazards, Do not use any other kind of AC adapter.
• When using the GFX-8 in an area with a different line voltage, please consult your local ZOOM distributor about acquiring a proper AC adapter.

- Environment

Avoid using your GFX-8 in environments where it will be exposed to:

• Extreme temperature
  High humidity or moisture
• Excessive dust or sand
• Excessive vibration or shock

Handling

Since the GFX-8 is a precision electronic device, avoid applying excessive force to the switches and buttons. Also take care not to drop the unit, and do not subject it to shock or excessive pressure.

- Alterations

Never open the case of the GFX-8 or attempt to modify the product in any way since this can result in damage to the unit.

- Connecting cables and input and output jacks

You should always turn off the power to the GFX-8 and all other equipment before connecting or disconnecting any cables. Also make sure to disconnect all cables and the AC adapter before moving the GFX-8.

Usage Precautions

- Electrical interference

For safety considerations, the GFX-8 has been designed to provide maximum protection against the emission of electromagnetic radiation from inside the device, and protection from external interference. However, equipment that is very susceptible to interference or that emits powerful electromagnetic waves should not be placed near the GFX-8, as the possibility of interference cannot be ruled out entirely.

With any type of digital control device, the GFX-8 included, electromagnetic interference can cause malfunctioning and can corrupt or destroy data. Care should be taken to minimize the risk of damage.

- Cleaning

Use a soft, dry cloth to clean the GFX-8. If necessary, slightly moisten the cloth. Do not use abrasive cleanser, wax, or solvents (such as paint thinner or cleaning alcohol), since these may dull the finish or damage the surface.

Please keep this manual in a convenient place for future reference.

Thank you for selecting the ZOOM GFX-8 (hereafter simply called the "GFX-8"). The GFX-8 is a sophisticated digital effect processor with the following features and functions:

- Versatile array of effects

The Variable Architecture Modeling System (VAMS) adapts the internal configuration of the unit to achieve exactly the desired pattern. The GFX-8 provides 69 effects ranging from the sound of famous guitar amplifiers and other vintage devices to ultra-modern processing functions. Up to nine effects can be freely combined for simultaneous use. Modulation effects and delay/reverb effects allow up to two types of custom settings to be stored in memory. Any desired setting can be called up quickly and easily.

Sophisticated distortion technology

Using new technology developed by Zoom, the GFX-8 can faithfully duplicate the characteristics of famous guitar amplifiers and preamplifiers. The available choices range from conventional overdrive to exciting high-gain fuzz sound. In combination with the built-in amp simulator and cabinet simulator, this lets you create realistic distortion tailored to your music. Two types of custom distortion are also included, letting you build your own sound from scratch.

"Easy Edit" feature

During a stage performance, quick editing is possible using handy selectors and knobs on the top panel of the unit. You can switch effects, adjust the 4-band equalizer, control distortion gain, or fine-tune major parameters of the delay/reverb effects. Operation is quick and intuitive, just like using a compact effect device.

MIDI capability

MIDI IN and OUT connectors are provided, allowing you to hook up a MIDI sequencer or keyboard for remote control, or to control a MIDI compatible guitar amplifier or other device from the GFX-8. Memory data can also be sent and received via the MIDI link.

- Supplied editing software

The GFX-8 is supplied with a CD-ROM containing software that lets you manage and edit patch libraries on a computer (Windows 95/98 or Macintosh). The software also provides access to a user custom area for detailed adjustments that are not possible on the main unit.

- Extensive patch library

A patch is a combination of effects and parameter settings stored in memory, with a name of up to 8 characters. The GFX-8 has room for 80 read/write patches (4 patches x 20 banks) that can be freely changed by the user, plus 160 preset patches (4 patches x 40 banks) that are read-only. In total, this gives access to as many as 240 patches.

Built-in sampler and jam play feature

The integrated phrase sampler has a recording time of up to 25 seconds. In addition, there is a jam play feature that lets you record a 12-second phrase and play it back in normal, reverse, or scratch mode. Changing the playback speed is possible without altering the pitch. This feature comes in handy when copying phrases. The AUX input lets you connect a stereo source such as a CD or MD player, to combine with your session or to directly record with the sampler.

- Designed for use on stage

The tough metal chassis of the unit will withstand use in a demanding environment. The expression pedal and foot switches are designed to facilitate your work on stage. The easy-to-read 8-character display plus a 2-digit LED panel are great for checking patch names, numbers, and other settings at a glance. The output level can be set to +4 dB to match professional specifications.

Please take the time to read this manual carefully so as to get the most out of your GFX-8 and to ensure optimum performance and reliability. Retain this manual, the warranty card and all other documentation for future reference.

This section explains some important terms that are used throughout the GFX-8 documentation.

■ Effect module

An "effect module" in the GFX-8 works like a stand-alone compact effect device such as a distortion or delay. In the GFX-8, you can

use the four effect modules DRIVE, EQUALIZER, MOD, and DLY/REV as well as the ZNR (Zoom Noise Reduction) + AMP SIM (Amp Simulator) simultaneously.

Signal flow in the GFX-8

Effects and parameters

An effect is a specific processing function in a module. The effect modules DRIVE, MOD, and DLY/REV each have 22 effects, from which one can be selected. The various settings of an effect that can be freely modified by the user are called parameters. The GFX-8 uses two kinds of parameters: effect parameters which are stored separately for each patch and global parameters which apply to all patches.

Patch/group/bank

Effect module combinations and effect parameter settings are stored in memory as "patches". The GFX-8 can store a total of 240 patches. These are divided into 80 read/write patches in the user groups (U and u) and 160 read-only patches in the preset groups (A, b, C, d). Each group has 10 banks numbered from 0 - 9, and each bank has 4 patches which can be selected with the foot switches 1 - 4 on the top panel of the unit.

■ Modes

The GFX-8 has five different operation modes, as listed below.

- Play mode

In this mode, patches can be selected and played. This is the default mode of the GFX-8 that is always active when power is turned on.

- Manual mode

In this mode, you play your instrument while manually switching modules on and off.

- Edit mode

In this mode, the effect parameters of the currently selected patch can be edited (changed).

- Jam play mode

In this mode, you can record a guitar phrase and play it back in normal, reverse, or scratch style.

- Sampler mode

In this mode, you can use the sampler function to record and play back a phrase from guitar or a source such as a CD player.

RTM (real-time modulation)

This refers to changing effect parameters in real time. For example, you can use the expression pedal to change the mix ratio of the reverb sound, or adjust the delay time during a song using a MIDI sequencer.

The type and range of the parameter to be changed, as well as the controller type (expression pedal or MIDI control change information) can be stored separately for each patch.

Connection Example (1) Instrument/amplifier connection

Connection Example (2) Connection to power amp input jack of guitar amplifier

If your guitar amplifier is equipped with a power amplifier input jack, you can directly connect the OUTPUT L/MONO jack of the GFX-8 to the power amp input jack, using the GFX-8 as a guitar preamplifier.

• When using the GFX-8 in this way, it is recommended to activate the built-in amp simulator (see page 7).

Connection Example (3) CD player/MD player connection

A component with stereo line level output such as a CD player or MD player can be connected to the AUX IN jack, using a stereo Y cable. The signal supplied to this jack is not processed by the effects of the GFX-8 and is sent directly to the OUTPUT jacks. This allows you for example to listen to a CD while practicing a guitar phrase.

• Using the sampler function of the GFX-8, it is also possible to record the signal supplied to the AUX IN jack (see page 34).
• When using hi-fi equipment (mixer, audio system or similar) instead of a guitar amplifier, activating the built-in amp simulator (see page 7) is recommended.

This section explains the steps you should take before playing sound through the GFX-8.

Power Up

1. Verify that the AC adapter, instrument, and amplifier/playback system are correctly connected to the GFX-8.

Before making any connections, be sure to turn power to all components off. Also, you should turn the volume on the amplifier or playback system to minimum, and set the

OUTPUT LEVEL knob on the rear panel of the GFX-8 to the 12 o'clock position.

1. Turn the system on in the order GFX-8 amplifier.
2. While playing your instrument, adjust the volume control on the amplifier, the level control of the instrument, and the OUTPUT LEVEL knob of the GFX-8 to a suitable position.

Setting up the Amp Simulator

The GFX-8 incorporates an amp simulator that can duplicate the electrical characteristics and cabinet sound of various guitar amplifiers. Before starting to use the GFX- 8, we recommend that you set up the amp simulator so that it matches the connection type of the playback system or guitar amplifier. This will assure that you get optimum results from the GFX-8.

1. Immediately after turning on the GFX-8, press the TOTAL key.

The GFX-8 switches to the edit mode which allows you to change various internal settings. The TOTAL key flashes red, and the display shows "PATCHLVL".

Quick Guide (Trying Out the Unit)

The Quick Guide explains the basic steps for using the GFX-8 in play mode. This lets you use the unit right away, to check out what it can do.

Selecting the patch/bank number/group

In play mode, the name of the currently selected patch is shown on the display. The group and bank number of the patch can be checked on the GROUP/BANK indicator.

① To switch the patch within the same bank, press one of the foot switches 1 - 4
whose LED is not lit.
* If you press the foot switch whose LED is lit, the GFX- 8 goes into the bypass condition.
② To switch to a patch from another bank number or group, use the BANK UP/DOWN foot switches and the foot switches 1 - 4 to select the bank number and group.
- For details on patch/bank/group switching, refer to p. 10.

To alter the effect with RTM

RTM (real-time modulation) refers to changing an effect with the expression pedal in real time.

(1) Rock the expression pedal back and forth.

Move back and forth

The effect changes as the expression pedal is moved. The parameter that is controlled can be programmed for each patch. Try out this function to see which parameter changes for the stored patches.

② Push the expression pedal fully down.

Push fully down

The expression pedal incorporates a switch that operates when the pedal is pushed firmly down. The switch turns the module for which RTM control is possible on and off.

• For information on effects that allow RTM control, see p. 30.
• For more information on the use of the expression pedal, see p. 41.

To select other effects or adjust the effect intensity, use the easy edit function.

The steps listed below will result in a change of the patch sound quality and effect intensity.

① To adjust the patch sound quality, operate PARM knobs 1 - 4.

② To change the effect, use the DRIVE, MOD, DLY/REV selectors and keys.

Turn the selector to choose the desired effect in the respective module (DRIVE, MOD, DLY/REV).

Switches the respective module (DRIVE, MOD, DLY/REV) ON and OFF and switches the group for selectable effects.

③ To change the effect intensity, operate the GAIN, PARM SELECT, or PARM VALUE knob.

Adjusts a major parameter of the MOD module.

• During adjustment, the key for that module flashes.
• The parameter that can be adjusted differs for each patch.
• For more information on easy edit, see p. 11.
• For more information on full edit, see p. 14.

To store an adjusted patch

To store an edited patch, press the STORE key twice.

If required, change the store target with the BANK UP/DOWN foot switches and foot switches 1 - 4 before pressing the STORE key twice. Note that only patches in a user group can be selected as store targets.

If you press the CANCEL key before pressing the STORE key twice, the store procedure is aborted and the unit returns to the play mode.

• For more information on storing patches, see p. 18.

Other useful functions

• For information on using the amp simulator, see p. 7.
• For information on using the built-in tuner, see p. 12.
• For information on record/playback of phrases (sampler), see p. 34.
• For information on special playback of recorded phrases (jam play), see p. 32.

Listening to Patches (Play Mode Operation)

Selecting and playing patches stored in the memory of the GFX-8 is called "play mode". The GFX-8 is always in this mode immediately after being turned on. This section describes how to use the functions available in this mode.

Panel Indication in Play Mode

In play mode, the following information is shown on the panel.

Selecting a Patch

1. To switch patches in play mode, press a foot switch 1 - 4 whose LED is not lit.

In play mode, foot switches 1 - 4 serve to select a patch from the same group/bank. The LED of the currently selected foot switch is lit.

2 To select a patch from a different group/bank, press the BANK UP or DOWN foot switch to switch the group/patch, and then use the foot switches 1 - 4 to select the new patch.

For example, when the BANK UP foot switch is pressed repeatedly, the group/bank number changes as follows.

User group

The patch is not switched as long as you only switch the bank/group (changed section of GROUP/BANK indicator

flashes). It is switched only after you press one of the foot switches 1 - 4 (the flashing of the GROUP/BANK indicator stops).

If desired, you can limit the action of the BANK UP/DOWN foot switches to select only user group banks, or only preset group banks. To do this, press the GROUP key. With each push of this key, the selectable groups are cycled as follows.

Using the Easy Edit Function

To edit patches of the GFX-8, the user normally will activate the edit mode, select the desired parameter, and change the setting. However, it is also possible to switch effects in modules and change major effect parameters in play mode. This is called the easy edit function.

1. To switch the effect used in the DRIVE, MOD, or DLY/REV module, operate the selector and key for the respective module.

Switches the respective module (DRIVE, MOD, DLY/REV) ON and OFF and switches the group for selectable effects. With each push of the key, the unit cycles through the following three states.

Key out or slowly flashing red
Respective module is OFF.

Key lit/flashing red Module is ON and effect from group A (upper labels) is selected.

Key lit/flashing green Module is ON and effect from group B (lower labels) is selected.

When the effect is switched, the name of the new effect is shown on the display for about 2 seconds. The EDITED mark (. in the GROUP/BANK indicator lights up. This indicates that an effect parameter of this patch has been edited. The mark disappears when the setting is changed back to the original setting.

While only the effect group was switched, the previous effect is still active. The change does not occur until the selector for the respective module is operated. Therefore the selector position and the actual effect may differ during this interval.

1. To adjust a major parameter of each module, operate the following knobs.

[EQ] PRESENCE:

Adjusts boost/cut in the ultra-high frequency range.

[PARM knobs 1 - 4]

Adjust the following EQ module parameters.

[GAIN knob]

Adjusts a major parameter of the DRIVE module. In almost all patches, this is the GAIN parameter that determines the distortion intensity.

[PARM VALUE/ADJUST knob]

Adjusts a major parameter of the DLY/REV module.

When one of the above knobs is moved, the display shows the parameter name and the GROUP/BANK indicator shows the parameter value for about 2 seconds.

Which parameter is assigned to the GAIN knob, PARM SELECT/ADJUST knob, and PARM VALUE/ADJUST knob depends on which effect is selected for that module (see page 19 - 29).

• Trying to change effects or parameters which are set to OFF in the current module has no effect. In this case, the indication "OFF" is shown on the display.
• All changes made with the easy edit function are temporary. Settings revert to the original condition when the patch is switched. When wishing to keep the changes, you must store the patch (see page 18).

Using the Bypass (Mute)/Tuner Function

The GFX-8 incorporates an auto-chromatic tuner for guitars. To use the tuner function, the built-in effects must be bypassed (temporarily turned off) or muted (original sound and effect sound turned off).

1. To set the GFX-8 to the bypass (mute) condition, press and immediately release the foot switch 1 - 4 that has selected the currently active patch (the foot switch whose LED is lit).

In play mode, when you quickly press the foot switch whose LED is lit, the GFX-8 switches to the bypass condition. The foot switch LED now flashes and the indication "BYPASS" is shown on the display.

If you press a foot switch with lit LED for longer than 1 second and then release it, the GFX-8 switches to the mute condition. The foot switch LED now flashes and the indication "MUTE" is shown on the display.

1. Play the open string you want to tune, and watch the GROUP/BANK indicator. The GFX-8 automatically detects the pitch and the GROUP/BANK indicator shows the note which is closest to the current pitch.

For tuning, always play a single note. If you play a chord, the pitch will not be detected correctly.

1. When the GROUP/BANK indicator shows the desired note, perform fine tuning while watching the display.

1. Tune the other strings in the same way.
2. When tuning is completed, press the foot switch whose LED is flashing once more.

The GFX-8 returns to the play mode.

If desired, you can change the setting of the unit so that pressing the foot switch whose LED is lit will not activate the bypass/mute condition. For details, please refer to page 41.

Adjusting the Reference Pitch of the Tuner

After the GFX-8 is turned on, the tuner reference pitch is always "center A = 440 Hz". If desired, you can change the reference pitch. This is useful for example to match your instrument to another instrument or sound source whose pitch cannot be changed easily, such as an acoustic piano or a CD. To do this, first change the reference pitch of the GFX-8 and then use to to perform tuning of your guitar.

1. In play mode, press the foot switch 1 - 4 whose LED is lit, to set the GFX-8 to the bypass/mute condition.
2. Rotate the DLY/REV (PARM VALUE) knob to adjust the reference pitch. When this knob is operated, the current reference pitch is shown on the display. The initial setting is "440" (center A = 440 Hz).

The available setting range is "435" (center A = 435Hz ) - "445" (center A = 445Hz ) in 1-Hz steps.
3. When tuning is completed, once more press the foot switch whose LED is flashing.

The GFX-8 returns to the play mode.

When the GFX-8 is turned off and on again, the reference pitch will be reset to "440".

Switching Modules On and Off During Play (Manual Mode)

The condition where foot switches 1 - 4 can be used to switch the modules in a patch ON and OFF individually and where specific parameters can be adjusted is called "manual mode". In manual mode, the modules in a patch can be used like independent compact effects.

1. In play mode, select a patch.
2. Press the BANK DOWN foot switch and hold it down for at least 1 second.

The GFX-8 switches to the manual mode. The display shows "MANUAL".

1. Operatefoot switches1-4.

In manual mode, foot switches 1 - 4 have the following functions.

Foot switch 1
DRIVE module ON/OFF switching
Foot switch 4

Controls a parameter individually programmed for each patch, such as module bypass, delay time tap input, etc.

The parameter to be controlled by foot switch 4

(CONTROL switch) is set using the TOTAL module (see page 29).

1. To return to the play mode, press the BANK DOWN foot switch once more.

Changing the Sound of a Patch (Edit Mode)

The condition where you can change the parameters that make up a patch to create your own sound is called "edit mode". This section describes how to use edit mode.

Basic Edit Mode Steps

The basic steps that are normally taken in edit mode are explained here. Besides these, the edit mode also provides a short cut to quickly edit a specific parameter (see page 16).

1. In play mode, select the patch you want to edit.

The patch can be from a user group or preset group. However, because patches in the preset groups are read-only, after you have edited a patch, you can only select a user group patch as store target.

1. Press the EDIT key.

The EDIT key LED lights up, and the GFX-8 enters the edit mode.

In edit mode, the following information is shown on the panel.

The keys and foot switch LEDs of modules that are ON in the current patch are lit.

The key of the module selected for editing flashes.

When edit mode was activated immediately after switching patches, the TOTAL key flashes. When edit mode was activated after easy edit, the key of the edited module flashes.

1. Use the panel keys to select the module you want to edit.

In edit mode, the following keys serve to select the module for editing. The selected key flashes.

ZNR/EQ EDIT key

Selects the EQ module or ZNR.

With each push of the key, the color of the flashing LED changes, and the edit target changes as follows.

Flashing red

EQ module page 1

Flashing green

EQ module page 2

Flashing orange

ZNR

TOTAL key

Serves to set the patch name and patch level (overall output level of the patch) and other parameters applying to the entire patch, as well as global parameters that apply to all patches. With each push of the key, the color of the flashing LED changes, and the edit target changes as follows.

Flashing red

Flashing green

Flashing orange

Set patch name and patch level.

Set RTM and CONTROL switch functions (see page 30).

Make amp simulator (global parameter) settings.

If a module is selected that is set to OFF in the current patch, editing is not possible (display shows "OFF").

However, ZNR settings can be made also when the EQ module is OFF.

1. Use the PARM SELECT knob to select the parameter you want to edit.

When you turn the PARM SELECT knob, the effects of the module selected in step 3 and the effect parameters are shown in turn on the display. (Which parameter is shown depends on the currently selected module and effect). The currently selected parameter setting can be checked using the GROUP/BANK indicator.

5. Use the PARM VALUE/ADJUST knob to change the parameter setting (or the effect).

To change the parameter shown on the display, use the PARM VALUE/ADJUST knob. When a change is made to any effect selection or parameter, the EDITED mark (. ) appears on the GROUP/BANK indicator.

6. To change the effect module ON/OFF setting, use the following foot switches or keys.

In edit mode, the following keys or foot switches can be used to change the module ON/OFF setting. The key of a module that has been set to OFF goes out, and the module cannot be edited any more. (However, the ZNR settings can be changed also if the EQ module is OFF.)

(^1) Each push of the key: group A, group B, OFF
(^2) Each push of the key: ZNR (orange) EQ page 1 (red) EQ page 2 (green). When EQ page 1 or 2 is selected, keeping the key depressed for 1 second switches EQ ON or OFF.

1. When wishing to continue editing other parameters or modules, repeat steps 3 - 6.

8. When editing is complete, press the EDIT/CANCEL key.

The GFX-8 returns to the play mode.

All changes made in edit mode are temporary. Settings revert to the original condition when the patch is switched. When wishing to keep the changes, you must store the patch (see page 18).

In edit mode, the following knobs and keys can be used to directly edit the effect selection or parameter.

[DRIVE/MOD/DLY/REV selector]

[DRIVE/MOD/DLY/REV key]

Switches the respective module (DRIVE, MOD, DLY/REV) ON and OFF and switches the group for selectable effects. With each push of the key, the unit cycles through the following three states.

Key out or slowly flashing red

Respective module is OFF.

Key lit/flashing red

Module is ON and effect from group A (upper labels) is selected.

Key lit/flashing green

Module is ON and effect from group B (lower labels) is selected.

When the effect is switched, the name of the new effect is shown on the display for about 2 seconds.

Edit Mode Shortcut (2)

Using PARM knobs 1 - 4, the main parameters of each module can be quickly edited.

1. Use the DRIVE, MOD, DLY/REV, ZNR/EQ EDIT, or TOTAL key to select the module you want to edit.

The selected key starts to flash.

1. Use the PARM knobs 1 - 4 to edit the parameter selected in step 1.

In edit mode, the main parameters (parameter 1 - 4) of the currently selected module are assigned to PARM knobs 1 - 4.

For example, when the effect OVER DRV of the DRIVE module is selected, the PARM knobs 1 - 4 control the following parameters.

Creating Custom Distortion

The effect numbers 11A and 11B of the DRIVE module are reserved for custom distortion effects created by the user. For custom distortion, in addition to the regular effect parameters (PARM1 - PARM8), there are four more parameters (PARM9 - PARM12) which allow control over the distortion character and other characteristics.

PARM 9 >CHAR < Distortion character
PARM 10 > HIGH < High-range character
PARM 11 > MID < Mid-range character
PARM 12 > LOW < Low-range character

Once you have set these parameters and stored the result as a patch, you can use it as a new distortion effect in other patches.

1. Activate edit mode.
2. Select CUSTOM1 (11A) or CUSTOM2 (11B) of the DRIVE module.

Verify that the DRIVE module is ON.

1. Call up parameters 1 - 8 and make the desired settings.

To make optimum use of custom distortion parameters, we recommend to set parameters 1 - 4 as follows.

PARM1 GAIN 1-30(as desired)

PARM2 PRE GAIN 7

PARM3 TONE 5

PARM4 LEVEL 25

1. Press the GROUP/CUSTOM SET key once.

This calls up parameter 9. The name of the parameter (">CHAR<") appears on the display, and the GROUP/BANK indicator shows the current value.

Parameter 9 can also be called up with the PARM SELECT knob. This is convenient to switch between any parameter from 1 - 12.

1. Use the PARM VALUE knob to adjust the value.
   Parameters 9 - 12 are special parameters for custom distortion, allowing setting characteristics separately for each frequency band.
2. Call up parameters 10 - 12 in the same way with the PARM SELECT knob, and use the PARM VALUE knob to adjust the value.
3. When you have created a custom distortion effect, store the patch.

That parameters 9 - 12 are global parameters that affect all patches. For example, when parameters 9 - 12 of custom distortion 1 in a patch were adjusted, and the patch was stored, the changes will affect all patches using custom distortion 1 (effect type 11A).

Storing Custom Module Settings

The settings for the MOD module and DLY/REV module can be stored as custom settings. Stored custom settings can be called up at any time in edit mode, for use with new patches or existing patches.

The operation steps are different than for creating custom distortion in the DRIVE module.

1. Activate edit mode.
2. Press the MOD key or DLY/REV key to select the module for which you want to store custom settings.

Verify that the selected module is ON.

1. Make the desired effect selection and parameter settings for the module selected in step 2.
2. Press the GROUP/CUSTOM SET key.

The effect name flashes on the display, and the indication "C1" flashes on the GROUP/BANK indicator.

When the respective module is OFF, custom module settings cannot be stored.

1. Press the GROUP/CUSTOM SET key and select C1 (custom setting 1) or C2 (custom setting 2).
2. To store the custom settings you have made, press the STORE key.

The stored custom settings can be selected at any time, simply by choosing 11A (custom setting 1) or 11B (custom setting 2) for the MOD module or DLY/REV module.

To cancel the store process, press the CANCEL key.

Storing and Copying Patches (Store Mode Operation)

Unless you store edited patches in memory, the settings will revert to the original condition when the patch is switched. Do not forget to store any edited patches that you wish to keep.

It is also possible to copy an existing patch and store it at another location. For example, copying all patches to be used in a specific song to one user group bank will make it easy to call up the patches with foot switches 1 - 4 during a performance.

1. In play mode or edit mode, press the STORE key.

The GFX-8 goes into store standby mode and the indication "STORE?" and the store target patch name are shown alternately on the display. The GROUP/BANK indicator shows the store target group/bank number. The LED of one of the foot switches 1 - 4 corresponding to the store target lights up.

If you wish to store the edited patch in another location than the currently shown store target, change the patch name before pressing the STORE key.

1. Use the BANK UP/DOWN foot switches and foot switches 1 - 4 to select the store (copy) target.

When the edited patch was from a user group, the original group/bank/foot switch will be selected as store target if no

other steps are taken. When the group/bank is changed, the changed part of the GROUP/BANK indicator flashes.

1. To execute the patch store (copy) process, press the STORE key once more.

The store (copy) process is carried out, and the unit automatically reverts to the play mode.

To cancel the operation, press the CANCEL key before pressing the STORE key the second time.

• The patches in the preset groups (A, b, C, d) are read-only and cannot be used as store targets. When the STORE key is pressed while a patch from a preset group is selected, the store target is automatically changed to "U0" and foot switch 1. If required, change the store target with the USER group/bank/foot switch.
• When the store (copy) process is executed, the previous contents of the store (copy) target are overwritten and cannot be restored. However, the factory default settings of any user group patch (or all patches) can be restored (see page 41).

Using RTM

The RTM (real-time modulation) function can be operated either with the expression pedal on the top panel or by MIDI control change messages input via a MIDI link. This can be used for example to change the reverb sound mix ratio during a performance, using the expression pedal, or to control effect parameters during play, using a MIDI sequencer.

The parameter to be controlled by RTM as well as the control range can be freely set in edit mode. The steps for setting up and using RTM are as follows.

1. In play mode, select a patch for which RTM is set.
2. Switch to edit mode, and use the DRIVE, ZNR/EQ EDIT, MOD, DLY/REV keys to select the module to be controlled by RTM.
3. Turn the PARM SELECT knob until the display shows "RTM CTL".

RTM CTL is the parameter that selects the controller for the RTM action. The following settings are possible.

oF

RTM is not used in the module.

Pd

RTM is controlled with the expression pedal on the unit.

1-5,8-31

RTM is controlled with the MIDI control change of the respective control number.

1. Turn the PARM VALUE knob to select "Pd".

The respective module can now be controlled with the expression pedal.

1. Turn the PARM SELECT knob until the display shows "RTM DES".

RTM DES selects which effect parameter in that module is controlled by RTM.

1. Turn the PARM VALUE knob to select the number of the parameter (1 - 4) to be controlled by RTM.
2. Turn the PARM SELECT knob until the display shows "RTM MAX", and use the PARM VALUE knob to set the maximum value of the parameter.

For the effect parameter selected in step 6, RTM MAX determines the maximum value that is established when the expression pedal is pushed fully down (or when the value of the received MIDI control change is 127).

Taking the maximum value of the controlled parameter as 100 (%) , the setting can be made from 0% - 100% (setting value = 0 - 99, 1.0).

1. Turn the PARM SELECT knob until the display shows "RTM MIN", and use the PARM VALUE knob to set the minimum value of the parameter.

For the effect parameter selected in step 6, RTM MIN determines the minimum value that is established when the expression pedal is fully raised (or when the value of the received MIDI control change is 0).

Taking the maximum value of the controlled parameter as 100 (%) , the setting can be made from 0% - 100% (setting value = 0 - 99, 1.0).

It is also possible to set RTM MIN to a higher value than RTM MAX. For example, if the setting is RTM MAX = 0, RTM MIN = 1.0, the parameter for that module becomes smaller as the pedal is pushed and maximum when the pedal is raised.

1. Repeat steps 2 - 8 to make the RTM setting for other modules in the same way.

The RTM parameters described above are available separately for the DRIVE, EQ, MOD, DLY/REV modules. This makes it possible to control several parameters in different modules simultaneously.

It is also possible to assign the volume control to the expression pedal. This setting is made with the VOL_RTM parameter (see page 29) in the TOTAL module.

1. Store the patch and return to play mode.

When the expression pedal is operated in this condition, the assigned parameter changes within the preprogrammed range.

When the parameter was set to MAX=1.0 (100%), MIN=0 (0%), the expression pedal changes the parameter as follows.

When the parameter was set to MAX=0 (0%), MIN=1.0 (100%), the expression pedal changes the parameter as follows.

1. To switch the effect module being controlled by RTM on and off, push the expression pedal fully down.

The expression pedal of the GFX-8 incorporates a push-down switch that is activated when the pedal is pushed fully down in play mode. The switch serves to turn the RTM controlled module on and off.

For example, use the edit mode to set the DRIVE and MOD modules to RTM control, so that one module is on and the other module is off, and store the patch. When you call up this patch in play mode, you can switch between RTM control of the two modules each time you fully depress the expression pedal.

Using the CONTROL Switch

When the GFX-8 is in manual mode or edit mode, the CONTROL switch (foot switch 4) can be used for real-time control. If you program the module to be controlled beforehand, you can for example use the CONTROL switch during a performance to boost the DRIVE module or to input the delay time with tap input.

1. Select the patch for which you want to use the CONTROL switch.
2. Press the TOTAL key twice, so that the LED is flashing green.
3. Use the PARM knob 2 to assign a module to the CONTROL switch.

While the TOTAL key is flashing green, turning the PARM knob 2 sets the CT SW parameter which selects the module to assign to the CONTROL switch.

The following settings are available.

• oF CONTROL switch is not active for this patch.
• dS CONTROL switch controls DRIVE module.
• Eq CONTROL switch controls EQ module.
• Md CONTROL switch controls MOD module.
• rv CONTROL switch controls DLY/REV module.

The actual function performed when pressing the CONTROL switch depends on the module and effect (see page 19 - 29).

1. Store the patch and return to play mode.
2. Hold the BANK DOWN key down for at least 1 second to activate the manual mode.

The function assigned to the CONTROL switch is active in manual mode (and edit mode).

1. Push the CONTROL switch.

The function assigned to the CONTROL switch in that patch can be carried out. (For each effect, one of the following functions is assigned. This assignment is fixed and cannot be changed.)

• Boost on/off

The switch serves to further boost the DRIVE module. This function can be used for all effects in the DRIVE module.

• Module bypass/Mute

While the CONTROL switch is being pressed, the module effect is bypassed. Can be used for the EQ module and some effects of the MOD and DLY/REV modules.

• Tap input

The delay time setting can be made (edited) by pressing the CONTROL switch in the desired interval. Can be used for delay effects in the MOD and DLY/REV modules.

Parameter value increase/decrease

While the CONTROL switch is being pressed, the rate parameter of the flanger effect etc. becomes maximum.

1. To return to the play mode, press the BANK DOWN key once more for at least 1 second.

Using the Jam Play Feature

The GFX-8 incorporates a jam play function which allows you to record and play a guitar phrase of up to 12 seconds in length. Besides straight playback, there are also innovative features such as reverse play and scratch play where you can use the expression pedal to control the direction and speed of playback.

To use the jam play function, prepare a patch which uses the JAM PLAY effect from the DLY/REV module, and make the desired settings for playback method and foot switch operation.

1. Select a patch in which you wish to use jam play.
2. Switch to edit mode and select JAM PLAY (effect 7A) in the DLY/REV module (see page 26). Make sure that the DLY/REV module is ON.

3. Use the PARM knob 1 to select the desired STYLE parameter (playback method for the recorded phrase).

4. nM (Normal) Playback in normal direction.

5. rS (Reverse) Playback in reverse direction.
6. SC (Scratch) Playback direction changes according to the movement direction and speed of the expression pedal, resulting in a scratch type effect.

When switching to scratch playback from another playback method, or when switching to another playback method from scratch playback, previous recording data are erased. When scratch playback is selected, the maximum recording time is 2 seconds.

Scratch play

1. When the STYLE parameter was set to "nM" (Normal) or "rS" (Reverse), use the PARM knob 2 to select the TRIG/GT parameter (trigger/gate mode).

tS (trigger one-shot)

Pressing the / foot switch (foot switch 2) causes one-time playback from the beginning.

Pressing the foot switch during playback stops play.

tL (trigger loop)

Pressing the / foot switch causes loop playback from the beginning.
Pressing the foot switch during playback stops play.

GS (Gate one-shot)

While the / foot switch is pressed, one-time playback from the beginning is carried out.

Releasing the foot switch during playback stops play.

GL (Gate loop)

While the / foot switch is pressed, loop playback from the beginning is carried out.
Releasing the / foot switch during playback stops play.

rS (retrigger one-shot)

Pressing the foot switch causes one-time playback from the beginning.
Pressing the / foot switch during playback restarts play.

When the STYLE parameter is set to "SC", this parameter has no effect.

When the JAM PLAY effect is selected for the DLY/REV module, the expression pedal and CONTROL switch are automatically assigned to the jam play feature.

1. Store the patch and return to play mode.

In play mode, when a patch is selected where jam play can be used, the DLY/REV key flashes.

1. To activate jam play, push the expression pedal fully down in play mode, or press the CONTROL switch in manual mode.

The GFX-8 enters the jam play mode and goes into the recording standby condition. The display shows "STOP", and "JP" flashes on the GROUP/BANK indicator.

1. While playing your instrument, press the REC foot switch (foot switch 3).

The indication "RECORDING" scrolls on the display and recording starts.

For jam play, the recording source signal is always the processed effect signal. When "nM" or "rS" is selected as STYLE parameter, the expression pedal can be used to adjust the input signal level.

1. To stop recording halfway, press the / foot switch (foot switch 2).

Recording stops, and playback starts according to the selected settings.

When the / foot switch was not operated, recording stops automatically after 12 seconds have elapsed, and playback starts according to the selected settings.

1. Use the / foot switch (foot switch 2) and expression pedal to control playback/stop of the recorded phrase.

When "SC" was selected as STYLE parameter, the expression pedal can be used for scratch playback. If "nM" or "rS" was selected as STYLE parameter, the expression pedal can be used to control the jam play volume.

To record a new phrase, repeat steps 7 - 9.

1. To terminate jam play, press the expression pedal once more fully down, press the EDIT key, or press the CONTROL switch.

Using the Sampler

The GFX-8 incorporates a sampler with a maximum recording duration of 25 seconds. It can be used not only to record the guitar input but also the signal from an external component such as a CD player or similar. The recorded sample is stored in memory and can be easily played back using the foot switches.

1. Refer to the diagram on page 6 and connect the recording source to the INPUT jack or AUX IN jack of the GFX-8.

Before changing any connections, be sure to turn the OUTPUT knob fully to zero. If plugs are inserted or removed with the OUTPUT turned up, transient noise can occur which can damage the speakers of the playback system.

1. Select the patch in which you wish to use the sampler.
2. Switch to edit mode and select SAMPLER (effect 7B) in the DLY/REV module (see page 27). Make sure that the DLY/REV module is ON.

When S AMPLER is selected for the DLY/REV module, the MOD module is automatically set to OFF.

1. Use PARM knobs 1 - 4 to select the sampler parameters, as follows.

PARM knob 1 SOURCE parameter (recording source selection)

The following settings are available.

• PL = Guitar signal from INPUT jack (after passing EQ module/amp simulator)
• AU = Signal from AUX IN jack (signal does not pass any effect module)

PARM knob 2 PITCH parameter (pitch compensation)

Sets pitch compensation to ON (on) or OFF (oF). When the PITCH parameter is ON, the pitch will be kept constant also when changing the playback speed with the SPEED parameter (PARM knob 3).

PARM knob 3 SPEED (playback speed)

Sets the sampler playback speed. When pitch compensation is not carried out with the PITCH parameter, the pitch changes as follows, according to the SPEED parameter.

1.0 original pitch
94,89,84,79,75,71,67

(1 semitone down - 7 semitones down)

• 50 (1 octave down)
  25 (2 octaves down)

PARM knob 4 TONE

Adjusts the playback tone. Settings from -10 to -1 mean a low-range cut and settings from 1 to 10 a high-range cut.

1. Store the patch and return to play mode.

For patches where SAMPLER is selected as effect for the DLY/REV module, the DLY/REV key LED flashes green.

1. To activate the sampler, push the expression pedal fully down in play mode, or press the CONTROL switch in manual mode.

The following information appears on the display and the indication "SM" flashes on the GROUP/BANK indicator.

1. Press the REC foot switch (foot switch 3) and play the phrase you want to record (or start playback at the CD player or other external device).

The indication "RECORDING" scrolls on the display and recording starts.

1. To terminate the sampler function, press the expression pedal once more fully down, press the EDIT key, or press the CONTROL switch.

The recorded contents are cleared when the sampler function is terminated.

This section describes various application examples of the GFX-8 using MIDI.

Basic MIDI Send/Receive Settings

Before using the various possibilities, basic settings for sending and receiving MIDI messages (Omni mode on/off, send/receive channel, etc.) must be made, as described below. MIDI settings are global parameters that apply to all patches. The settings are memorized also when the unit is turned off.

1. In play mode or edit mode, press the MIDI key.

The MIDI key lights up, and the unit enters the MIDI utility mode. The GROUP/BANK indicator shows the setting item number, and the display shows the setting value.

2. Use the PARM SELECT knobs 1 - 4 to select the item, and use the PARM VALUE knob to change the value.

Item numbers, setting contents, and setting values are listed below.

01 RXCH (MIDI receive channel)

Setting value: 01 - 16

Sets the MIDI channel in which the GFX-8 receives MIDI messages.

02 TXCH (MIDI send channel)

Setting value: 01 - 16

Sets the MIDI channel in which the GFX-8 sends MIDI messages.

03 MIDI OUT/THR (MIDI OUT connector function)

Setting value: OUT, THR

Sets the function of the MIDI OUT connector to "OUT" (MIDI OUT connector) or "THR" (MIDI THRU connector). When wishing to transmit GFX-8 operation information to an external device, select "OUT".

When MIDI THRU is selected, the GFX-8 will not send out any MIDI messages, and all functions related to MIDI message output are disabled.

3. When the settings are complete, press the EDIT key.

The settings are stored, and the unit returns to the play mode.

Switching GFX-8 Patches From an External Unit

You can send MIDI messages from an external MIDI device to the GFX-8 and switch patches at the GFX-8 in this way. To do this, connect the MIDI OUT connector of the external MIDI device to the MIDI IN jack of the GFX-8, using a MIDI cable. Set the MIDI send channel at the external MIDI device and the MIDI receive channel (RXCH) at the GFX-8 to the same settings.

To switch patches, you can either use bank select + program change information to switch the patch directly, or you can use the program change map built into the GFX-8 to call up patches indirectly.

■ Specifying Patches Directly

You can use bank select + program change messages to directly specify any group, bank number, and patch number of the GFX-8. Proceed as follows.

1. In play mode or edit mode, press the MIDI key.

The MIDI key lights up, and the unit enters the MIDI utility mode.

2. Turn the PARM SELECT knob so that the GROUP/BANK indicator shows "14".

The display shows "PC FIX" or "PC MAP".

3. If necessary, use the PARM VALUE knob so that the display shows "PC FIX", and then press the EDIT key.

The GFX-8 returns to the play mode.

4. To switch GFX-8 patches under external control, send messages in the following order.

• Bank select MSB (control change number: 0/value: 0)
  Bank select LSB (control change number: 32/value: 0 - 2)
  Program number (0 - 79)

The relationship between GFX-8 patches and bank select MSB/bank select LSB/program number is as shown below.

• Always use the sequence: bank select MSB, bank select LSB, program number. If the order is changed or if another message is inserted, the GFX-8 may disregard the command.
• When bank select information is omitted and the GFX-8 receives only a program number, it will use the last received bank select (default settings: MSB = 0, LSB = 0).

■ Specifying Patches Via PC Map

The GFX-8 incorporates a so-called program change map that maps MIDI program numbers to GFX-8 patches. Using the program change map, you can make program change numbers 0 - 127 call up any desired patch.

1. In play mode or edit mode, press the MIDI key.

The MIDI key lights up, and the unit enters the MIDI utility mode.

1. Turn the PARM SELECT knob so that the GROUP/BANK indicator shows "14".

The display shows "PC FIX" or "PC MAP".

1. Turn the PARM VALUE knob until the display shows "PC MAP".

The program change map is now active.

1. Next, turn the PARM SELECT knob until the GROUP/BANK indicator shows "PC".

The program change map is selected as setting item. The display shows the MIDI program number (P000 - P127) and the group (U, u, A, b, C, d), bank number (0 - 9), and patch number (1 - 4) assigned to that number.

1. Turn the PARM SELECT knob to select the program number to assign to the patch.

When the above display has appeared, you can turn the PARM SELECT knob to change the program number.

1. Turn the PARM VALUE knob to select the group, bank number, and patch number to assign to the currently shown program number.

You can use the BANK UP/DOWN foot switch and foot switches 1 - 4 to specify the respective group, bank number, and patch number.

1. Repeat steps 5 and 6 until all desired program numbers have been mapped to their respective patches.

If desired, you can also assign several program numbers to the same patch.

1. When the entire assignment process is completed, press the EDIT key.

The program change map is stored, and the unit returns to the play mode.

1. Send a program change message from the external MIDI device.

The patch assigned to the program number will be called up.

• When using the program change map, there is no need to send bank select information from the external MIDI device.
• The program change map is active only for receiving MIDI messages. The program number information sent by the GFX-8 when patches are switched is fixed (see page 36).

Controlling External Devices in Conjunction With GFX-8 Patch Switching

When you switch a patch with the controls on the top panel of the GFX-8, the unit can send program change information and control change information to an external MIDI device. To do this, connect the MIDI OUT connector of the GFX-8 to the MIDI IN jack of the external MIDI device, using a MIDI cable. Set the MIDI send channel at the GFX-8 and the MIDI receive channel (RXCH) at the external MIDI device to the same settings.

This function of the GFX-8 can be set up in two ways, as follows:

GFX-8 sends only bank select information + program change information when the patch is switched GFX-8 sends bank select information + program change information followed by two types of control change information (CT1 + CT2).

To Send Only Bank Select + Program Change Information

To set up the GFX-8 so that it sends bank select information + program change information corresponding to a patch, proceed as follows. This is useful for example to switch programs at a MIDI compatible amplifier or effect device when a patch is switched at the GFX-8.

1. In play mode or edit mode, press the MIDI key.

The MIDI key lights up, and the unit enters the MIDI utility mode.

1. Turn the PARM SELECT knob so that the GROUP/BANK indicator shows "04".

The display shows "PCOUT ON" or "PCOUT OF".

1. If required, turn the PARM VALUE knob so that the display shows "PCOUT ON", then press the EDIT key.

The program change output is now enabled, and the GFX-8 returns to the play mode.

1. Switch a patch at the GFX-8. The bank select MSB, bank select LSB, and program change corresponding to that bank is output.

For information on the relationship between GFX-8 patches and bank select MSB/bank select LSB/program number, see the table on page 36.

To Send Control Change Information

Besides pedal and foot switch operation, the GFX-8 can be set up so that it sends two types of control change information (called CT1 and CT2) immediately after sending bank select + program change information when a patch is changed. The control number and value of CT1 and CT2 can be defined freely and stored separately for each patch. For example, this is useful to control the volume setting at a MIDI compatible amplifier or synthesizer.

1. In play mode or edit mode, press the MIDI key.

The MIDI key lights up, and the unit enters the MIDI utility mode.

1. Turn the PARM SELECT knob so that the GROUP/BANK indicator shows "05".

The display shows "CTOUT ON" or "CTOUT OF".

1. If required, turn the PARM VALUE knob so that the display shows "CTOUT ON", then press the EDIT key.

The control change output is now enabled, and the GFX-8 returns to the play mode.

This setting affects all control change output operations of the GFX-8.

1. Press the TOTAL key twice, so that the LED flashes green.

Page 2 of the TOTAL module can now be edited.

1. Turn PARM knob 3 and select the control number for CT1 (control change sent immediately after program change).

The display shows "CT1->XX" (XX is the control number), and the GROUP/BANK indicator shows the value. Use PARM knob 3 to set the control number for CT1. Available settings are of F (OF), 1 - 5, 7 - 31, 64 - 95.

1. Turn the PARM VALUE knob to set the value for CT1 to 0 - 127 (0 - 99, 0.0...2.7).

2. Turn PARM knob 4 to select the control number for CT2 (second control change sent after program change).

1. Turn the PARM VALUE knob to set the value for CT1 to 0 - 127 (0 - 99, 0.0...2.7).
2. Store the patch and return to play mode.
3. Call up the respective patch.

The following MIDI message sequence is output from the MIDI OUT connector: bank select MSB bank select LSB program change CT1 CT2.

Remote Control Using GFX-8

It is possible to send out MIDI control change information whenever a control on the GFX-8 is operated, or conversely, to operate the GFX-8 via externally supplied control change information. This lets you for example record a GFX-8 operation sequence on a MIDI sequencer and play it back at any time. Remote control of the GFX-8 from other external equipment is also possible.

To control external equipment from the GFX-8, connect the MIDI OUT connector of the GFX-8 to the MIDI IN connector of the external device. To control the GFX-8 from external equipment, connect the MIDI OUT connector of the external device to the MIDI IN connector of the GFX-8. (For information on enabling or disabling control change information output, please refer to "To Send Control Change Information" on page 37.)

1. In play mode or edit mode, press the MIDI key.

The MIDI key lights up, and the unit enters the MIDI utility mode.

1. Use the PARM SELECT knob to select items 6 - 13, and use the PARM VALUE knob to change the setting value.

The item numbers, setting contents, and setting values are shown below.

06

EXPP (expression pedal send control number)

setting value: OF, 1 - 5, 7 - 31

Sets the control number for the control change information sent when the expression pedal is operated.

This is a send-only parameter. The internal parameter setting of the GFX-8 is not affected also when the GFX-8 receives this control number.

07

DRIVE (DRIVE module on/off receive control number)

Setting values: OF, 64 - 95

08

MOD (MOD module on/off receive control number)

Setting values: OF, 64 - 95

09

D/R (DLY/REV module on/off receive control number) Setting values: OF, 64 - 95

10

EQ (EQ module on/off receive control number)

Setting values: OF, 64 - 95

Sets the control number that is sent when a module is switched on and off at the GFX-8. The respective module is also switched when the GFX-8 receives that control change information from an external device.

11

BYPAS (bypass operation receive control number) Setting values: OF, 64 - 95

12

MUTE (mute operation receive control number)
Setting values: OF, 64 - 95

Set the control number that is sent when bypass/mute is switched on and off at the GFX-8. Bypass/mute is also switched when the GFX-8 receives that control change information from an external device.

13

CTSW (CONTROL switch operation receive control number)

Setting values: OF, 64 - 95

Sets the control number that is sent when the CONTROL

switch is operated at the GFX-8.

3. When the setting is complete, press the EDIT key to return to play mode.

When panel keys or switches are operated in this condition, the respective control change is output from the MIDI OUT connector. When a control change message is received from external equipment, the respective item changes. The values that can be received for the various items are listed below.

Example:

Control number 70 is assigned to DRIVE module on/off

When the DRIVE module is switched on or off at the GFX-8 itself, the MIDI OUT connector supplies the following control change information: control number = 70 , value = 127/0 .

When the control change information "control number = 70, value = 127/0" is supplied to the GFX-8 MIDI IN connector, the DRIVE module is switched OFF. When the control change information "control number = 70, value = 64 - 127" is supplied, the DRIVE module is switched ON.

While the jam play function or sampler function is activated, external MIDI control is not possible.

	Allowable values	Allowable values
EXPP	0 - 127 Continuously variable	--
DRIVE/MOD DLY/REV/EQ	0=OFF/127=ON	0 - 63=OFF/64 - 127=ON
BYPAS/MUTE	0=OFF/127=ON	0 - 63=OFF/64 - 127=ON
CTSW (For tap input)	When pushed: 127 = ON value output	--
	Immediately after: 0 = OFF value output	--
CTSW (when using push = ON function)	When pushed: 127 = ON value output	--
	When released: 0 = OFF value output	--
CTSW (when using push = ON/OFF toggle function)	When pushed and LED lights: 127 = ON value output	--
	When pushed and LED goes out: O = OFF value output	--

Bulk Dump

Patch information and program change map information stored in the GFX-8 can be output in bulk via the MIDI link. This function is called "bulk dump". You can use this function for example to store GFX-8 information on a MIDI sequencer or to exchange settings between two GFX-8 units.

1. Connect the MIDI OUT connector of the GFX-8 to the MIDI IN connector of the external MIDI device (other GFX-8, MIDI sequencer, etc.).
2. Set the GFX-8 to play mode and turn the PARM SELECT knob until the GROUP/BANK indicator shows "15".

3. Use the PARM VALUE knob to select the data type to use for the bulk dump operation.

4. ALL All settings of GFX-8

5. PAT All patch data
6. SYS All settings of GFX-8 except patch data
7. BUF Currently selected patch

8. DST DRIVE module user custom settings

9. After setting the external MIDI device to the recording mode, press the STORE key.

For example, when "ALL" was selected in step 3, the display shows "ALL OK?".

1. To execute the bulk dump operation, press the STORE key once more.

The display shows "DUMPING" and the GFX-8 starts to send the bulk dump data. To cancel the bulk dump operation, press the EDIT/CANCEL key before pressing the STORE key the second time. The unit returns to the play mode without carrying out the operation.

1. When the GFX-8 has returned to play mode, stop recording at the external MIDI device.

Perform any necessary steps to store the recorded information on the external MIDI device.

Bulk Load

GFX-8 patch information or program change map information stored on external equipment can be reloaded into the GFX- 8. This is called "bulk load".

1. Connect the MIDI OUT connector of the external MIDI device (other GFX-8, MIDI sequencer, etc.) to the MIDI IN connector of the GFX-8.

To perform bulk load, the GFX-8 must be set to the same MIDI channel as used when performing bulk dump. If the MIDI channel is different, playback at the external MIDI device will have no effect and will be disregarded by the GFX-8. When the GFX-8 is in store mode, received bulk data will be disregarded. Verify that the unit is not in store mode before proceeding.

1. Perform playback at the external MIDI device.

The settings of the GFX-8 are overwritten, depending on the type of received data.

• When saving data on an external device and when reloading the data to the GFX-8, the GFX-8 must be set to the same MIDI channel. If the MIDI channel is different, playback at the external MIDI device will have no effect and will be disregarded by the GFX-8.

• Playback at the external MIDI device must be performed at the same tempo as recording. If the tempo is faster, the GFX-8 may not receive the data properly.

• When bulk load is completed, stop playback at the external MIDI device.

When performing bulk dump or load with two GFX-8 units, hooking up both the MIDI IN and MIDI OUT connectors will result in faster data transfer.

Supplied Software

The GFX-8 comes with a CD-ROM that contains software for editing patches on a personal computer. (The disc contains versions for Windows 95/98 and Macintosh.) The software comprises the following functions.

(1) Patch librarian

Serves to manage patch information of the GFX-8 on the computer. Information about all patches of the GFX-8 is sent to the computer via a MIDI link and can be stored on the hard disk as a project file. Within a project, the order of patches can be changed, and information stored as project files can be loaded back into the GFX-8. In effect, this increases the memory capacity of the GFX-8 to an unlimited size.

(2) Visual editor

Using knobs, switches and other graphical elements appearing on the computer screen, patches contained in project files can be edited. Because the edited contents are sent immediately to the GFX-8 via the MIDI link, the effect of any editing operation can be checked immediately by listening to the sound. Edited patches can be stored on the computer and can also be sent to the GFX-8 via the MIDI link.

(3) DRIVE module custom setting editor

Using this software, you can edit additional parameters for the DRIVE module custom settings, to achieve even more detailed adjustments than are possible with the controls on the unit itself. There are virtually no limits to your creativity, as you can set numerous items such as balance for each frequency band, distortion circuit characteristics, etc. The editing results can be written back to the GFX-8.

• For information on software installation, please refer to the separate sheet. For information on how to use the software, please refer to the documentation included on the CD-ROM.
• The latest version of the software can be downloaded from the Zoom web site.

Other Functions

This section contains information about special functions such as how to return the GFX-8 to the factory default condition and how to readjust the expression pedal.

All Initialize/Factory Recall

The All Initialize/Factory Recall function is a special function that lets you reset the GFX-8 to the condition in which it was originally shipped. When All Initialize is performed, all settings of the unit including all user group patches are returned to the default condition. Factory Recall can be used to reset only specific user group patches group to the default settings.

1. Turn power to the GFX-8 on while keeping the STORE key depressed.

The display shows "ALL-INIT".

• To perform All Initialize
  Continue with the next step.

• To perform Factory Recall
  Use the BANK UP/DOWN foot switch and foot switches 1 - 4 to select the patch (from a user group) that you want to return to the factory default condition.

• Press the STORE key once more

All Initialize or Factory Recall is carried out. If All Initialize was carried out, the unit automatically returns to the play mode.

Note that when All Initialize is executed, the contents of all patches stored by the user will be overwritten (erased). When wishing to cancel All Initialize/Factory Recall, press the EDIT/CANCEL key before step 2.

Trying Out the Factory Default Patches (Self Introduction Function)

The GFX-8 also incorporates a so-called self introduction function that automatically switches patches to demonstrate the capabilities of the unit.

1. To activate the function, hold down the TOTAL key while turning on power to the unit.

The GFX-8 starts to automatically cycle through the factory-default patches.

The indication "SELF INTRODUCTION" and the currently selected patch name are scrolled on the display. You can play your guitar while checking out the various patches.

1. To stop the self introduction function, press the EDIT/CANCEL key.

Adjusting the Expression Pedal

The expression pedal of the GFX-8 uses a highly reliable optical sensor mechanism. The pedal is adjusted for optimum operation at the factory, but it can be readjusted as follows If required.

1. Hold down the GROUP key while turning on power to the unit.

The indication "MIN" appears on the display.

1. With the expression pedal fully raised, press the STORE key.

The display indication changes to "MAX".

1. Push the expression pedal down until it touches the stopper and then release the pedal. Press the STORE key at this point.

The adjustment is completed, and the unit returns to the play mode.

Disabling the Bypass/Mute Function

If desired, the setup of the unit can be changed so that the bypass/mute condition will not be activated also when the foot switch with the lit LED is pushed. This can help to prevent inadvertently switching to bypass/mute. To make the setting, proceed as follows.

1. Hold down the MIDI key while turning on power to the unit.

The display shows "BYP ENTR", and depending on the current setting, the indication "En" (bypass/mute function enabled) or "dS" (bypass/mute function disabled) is shown on the GROUP/BANK indicator.

1. Use the PARM VALUE knob to select the desired setting.
2. Press the STORE key.

The setting is stored and the GFX-8 switches to the play mode. If you press the CANCEL key instead of the STORE key, no change is made and the GFX-8 switches to the play mode.
