Frequently Asked Questions - V-4 ROLAND

How many video inputs does the Roland V-4 have and what types?

The V-4 has four video inputs: four composite (BNC) jacks and two S-Video (4-pin mini DIN) jacks. On channels 1 and 2, if both composite and S-Video are connected, the S-Video signal takes priority.

Can I synchronize video switching with music?

Yes. The V-4 offers BPM sync where you set the BPM (Beats Per Minute) numerically, or use the Tap button to tap along with the music. This allows automatic switching or effect application in time with the beat.

What is V-LINK and how do I use it?

V-LINK is a protocol that links musical instruments (e.g., Roland/Edirol synthesizers) with the V-4 for synchronized video control. Connect a V-LINK compatible device via MIDI, press the V-LINK button on the controlling device, and you can trigger video effects or switching from your instrument.

How do I composite two images using Picture in Picture?

Select the background image on channel A and the secondary image on channel B. Press the P in P button on channel B. Move the video fader to control the opacity of the secondary image. You can change the inset size and position via the menu settings.

What is the Memory dial and how many presets can I save?

The Memory dial stores up to eight panel states (effect assignments, transition types, etc.). Position 1 is a fixed factory preset; positions 2-8 are user-programmable. Turn the dial to recall a preset.

How do I perform a fade-to-black or fade-to-white?

Use the OUTPUT FADE dial on the front panel. Turning it toward BLACK fades the output to black; turning toward WHITE fades to white. The dial has an LED that turns red when away from center.

Can I control the V-4 with an external MIDI device?

Yes. Connect a MIDI controller to the MIDI IN port. You can assign MIDI Control Change messages to control parameters like video fader position, transition time, effects on/off, and more. Refer to the MIDI implementation chart in the manual for details.

What video formats does the V-4 support?

The V-4 supports both NTSC and PAL video formats. You can switch between them via the menu settings. It also accepts unstable signals (e.g., VHS) thanks to its frame synchronizers.

How do I clean and maintain the V-4?

For everyday cleaning, use a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water and a mild, non-abrasive detergent. Never use benzine, thinners, or alcohol as they may cause discoloration or deformation. Always unplug the unit before cleaning.

What should I do if the unit is not outputting video?

First, verify that source devices are correctly connected to the V-4 inputs and that the V-4 output is connected to the display. Check that the display's input selection matches the connected jack. Ensure the V-4 is powered on and that the selected input channel has a signal. If no signal is present, a blue screen appears (can be disabled in settings). If issues persist, consult the troubleshooting section of the manual.

Welcome

Thank you, and congratulations on your choice of the Edirol V-4. The V-4 is a video mixer/effects processor that delivers image quality rivaling professional equipment, and provides four channels of video input.

With a rich array of inputs and easy operation, the V-4 allows performances and presentations that include images to be made more expressive than ever before.

The V-4 can also be controlled from external MIDI devices. Images projected on the stage can be controlled while you play an instrument, adding impressive impact to a stage performance.

We hope you will enjoy the V-4's versatile video functionality in a wide range of applications.

Features of the V-4

Four-channels of video inputs

The V-4 provides two S-video inputs and four video (composite) inputs. Of the four channels 1 through 4, S-video can be used for inputs 1 and 2. If both S-video and video (composite) are input to channels 1/2, the S-video input will take priority and will be automatically selected.

Two independent frame synchronizers

Even when using unstable video input signals such as VHS and Hi-8, the frame synchronizers within the V-4 will correct the synchronization signal. This means you can use a wide range of image sources without worrying about noise produced by degradation of the synchronization signals.

High-quality digital effects

Effects are processed digitally. Diverse and high-quality effects such as Picture In Picture, Mirror, and Multi can be independently applied to both channels A and B.

Simple operation

Switching and mixing video sources is extremely easy. The T-bar type video fader can be installed in either the horizontal or vertical orientation, whichever you prefer.

Preview function

Before switching sources, you can use a preview TV screen to view the images being input on each channel without affecting the output image.

Switching and effects synchronized to music

The V-4 lets you tap BPM (Beats Per Minute) to switch images or control effects. This is particularly useful when music and video need to be synchronized, such as in a video jockey performance.

Control from external MIDI devices

The V-4 provides MIDI connectors. An external MIDI device can control effects and switching images. Setup is particularly easy if a Roland or Edirol product that supports V-LINK is connected—simply press the V-LINK button on the control device.

What is V-LINK?

V-LINK (V-Lanchot that links music and video performance, making it easy to create a variety of visual effects linked to the expressive elements of a performance.

By using V-LINK, musical instruments and music production equipment manufactured by Roland or Edirol can control video images without experiencing any loss in the quality of their inherent function (i.e., producing sound).

Connecting peripheral devices

This section explains how to connect your peripheral devices to the V-4. You can connect up to four video playback devices (sources). Here's how to connect sources such as a video camcorder, VCR, DVD player, or DV-7PR, and play them back to create an impressive video performance. To prevent malfunction and/or damage to other devices, always turn down the volume, and turn off the power on all devices before making any connections.

* The V4 does not have audio inputs so will not mix audio. Audio outputs can be connected directly to speakers or via an audio mixer if mixing of audio from multiple devices is necessary.

* No video cables come with this product. Please use appropriate video cables for connection with source devices or TV monitor/Projector.

* It is recommended to use composite cable rather than S-video cable where you need to connect devices long distances (unless using S-video amplifiers). If devices are installed closer to the V-4, it is recommended to use S-video cables so that you can obtain better image quality.

* If both video (composite) and S-video signals are input simultaneously to the same channel (channel 1 or 2 only), the S-video signal will take priority.

Connecting peripheral devices

Video signal flow

The video signals received from the four input jacks are assigned to channels A or B of the video mixer. (These assignments are made manually.) The signal of A and B channels are processed by the video mixer section, and sent via the output fader to the output jack.

Control the V-4 from an external device

Using V-LINK to control the V-4

You can connect the V-4 with a V-LINK compatible device made by Roland or Edirol, and control the V-4 remotely.

■ What is V-LINK?

V-LINK (V-LINK) on that allows images to be synchronized to music. V-LINK makes it easy to manipulate images in a variety of ways, while linking them to the expressive elements of a performance.

graph TD

    B --> C["MIDI OUT"]
    C --> D["V-LINK compatible device"]
    D --> E["EDIROL"]
    E --> F["In"]

(Example) When using a Roland MC-909 in conjunction with the V-4:

• You can make settings for controlling the V-4 from the MC-909 (remote settings).
• You can use the MC-909's sequencer to control video switching on the V-4 to create performances that link images with music.
• You can use the MC-909's velocity pads to control the V-4's input selectors and switch among images from various source devices.
• You can use the MC-909's knobs to adjust the time settings of transition effects (such as overlap or wipe).

(Example) When using an Edirol PCR-30/50 in conjunction with the V-4:

• You can make settings for controlling the V-4 from the PCR-30/50 (remote settings).
• You can use the PCR-30/50 to control the V-4's input selectors to switch between images from various source devices.
• You can use the PCR-30/50 to adjust the time settings of transition effects (such as overlap or wipe).

■ Using V-LINK

For details on how to turn V-LINK on/off, refer to the owner's manual of the V-LINK compatible device that you intend to connect to the V-4. When you turn V-LINK on, the indication "V-LINK" will appear in the preview monitor. When you turn V-LINK off, this indication will disappear.

When you turn on V-LINK on the connected device, the V-4 will switch to "Presentation mode." If the V-4 is operating in normal mode and receives a V-LINK "On" signal, the function of its buttons and other controls will change. (For details on Presentation mode, refer to p. 68.) When V-LINK is turned off, the V-4 will return to its previous settings.

For details on the functions that can be controlled from an external device via V-LINK, refer to MIDI Implementation (p. 89) and to the MIDI implementation of the device you have connected. The functions that can be controlled will differ depending on the device that is connected and on its settings.

Using MIDI to control the V-4

You can connect the V-4 with various MIDI devices for a wide range of remote control functionality.

■ What is MIDI?

MIDI stands for “Musical Instrument Digital Interface”—a worldwide standard that allows performance data and other information to be exchanged among musical instruments. MIDI-compatible devices can be connected together easily using MIDI cables. Once connected, performance data can readily be communicated between the two devices; or one can make settings for, as well as control the operation of the other device.

However, if you want to change the settings, you can use the following procedure. Although these settings can be made independently for channels A and B, they cannot be made independently for each input. You can also use the same procedure to change the output position of the image, or switch the video fader mode.

1. Press the menu button.

Press the menu button (MENU). The menu will appear in the preview screen.

Calibrating the video fader

With the factory settings, moving the V-4's video fader all the way to the A position will output 100% of channel A, and moving it all the way to the B position will output 100% of channel B. If for some reason, moving the video fader all the way to A or B does not output 100% of the image, you can use the following procedure to automatically calibrate the fader.

1. Move the video fader all the way to the A position.

First you will calibrate the channel A setting. Move the video fader all the way to the A position.

Using the V-4 in Presentation mode

The V-4 has two modes; Normal mode and Presentation mode. The preceding chapters have explained operation in Normal mode. This chapter explains how to use the V-4 in Presentation mode.

What is Presentation mode?

Presentation mode is ideal when using the V-4 in a presentation such as a meeting or exhibition. Using the V-4 in Presentation mode makes it easy to switch between inputs 1-4 or composite images using the Picture In Picture function.

Switching to Presentation mode

To switch from Normal mode to Presentation mode, turn off the power of the V-4. Then hold down channel A input select buttons 1 and 4, and press the power button.

Once you switch to Presentation mode, that setting will be preserved. The next time you start up the V-4, you can simply press the power button and the V-4 will start up in Presentation mode. If you want to start up in Normal mode, hold down the channel A input select buttons 1 and 4 while you press the power button.

■ The function of the input selector

Presentation mode assumes that you will be combining two screens. Use the channel A input selector to switch the background image. When you switch the background image in Presentation mode, the currently selected transition effect will automatically be applied.

Use the channel B input selector to switch the image of the secondary screen, the screen overlays on background.

■ The function of the BPM/CONTROL dial

Use the BPM/CONTROL dial to set the duration of the transition effect. If this dial is set to the far left, the transition effect will have a duration of 0 seconds. If set to the far right, the transition effect will have a duration of 4 seconds.

Presentations using two screens with Picture In Picture

Here's how you can composite two screens, a technique frequently used in presentations.

1. Switch the V-4 to Presentation mode.

Start up the V-4 in Presentation mode as described above.

If you want to start up in Normal mode and then switch to Presentation mode by making a menu setting, choose the "Utility" menu item "V-4 Mode" and then select "Presentation."

Using the V-4 in Presentation mode

2. Switch the background image.

Successively press the channel A input select buttons 1 through 4 to switch the image.

3. Apply the Picture In Picture function.

Set the memory dial to number 2. Picture In Picture will be applied.

4. Apply other effects to composite two images.

Turn the memory dial to other positions to try out other types of effects. Numbers 2 - 5 change the location of the secondary screen of the Picture In Picture function. Numbers 6-8 apply other effects (luminance key/chroma key).

5. Switch the secondary image.

Press the channel B input selector buttons to switch the secondary image.

Switching between NTSC and PAL

The V-4 can be switched to support either NTSC or PAL format signals. To start up in PAL mode, hold down preview select button 1 and "OUTPUT," and press the power button.

    M["INDIA: Redund Corporation, INCH. Germany"] --> N["Power Unit 1"]
    O["INCH. Germany"] --> P["Power Unit 2"]
    Q["N225 CE"] --> R["Output Comparison"]

The next time you start up, you can simply press the power button to start up in PAL mode. If you want to return to NTSC mode, once again hold down preview select button 1 and "OUTPUT", and press the power button.

When the V-4 starts up, an indication of whether it is starting up in NTSC mode or PAL mode will appear for several seconds in the preview screen.

Changing the video fader orientation

The V-4's T-bar style video fader may be installed in either the horizontal or vertical orientation depending on your preference. When shipped, the video fader is installed for vertical operation. If you prefer to operate the fader horizontally, you can turn the video fader 90 degrees.

1. Remove the screws.

Four screws fasten the video fader. Remove these four screws from the round video fader mounting plate, being careful not to lose them.

Pure mechanical component diagram without any text, numbers, or symbols

1. Reposition the video fader.

Turn the video fader 90 degrees. Align the triangle printed on the round mounting plate of the video fader with the triangle printed on the panel of the V-4.

Pure electrical circuit lines without any symbols

1. Fasten the screws.

Fasten the video fader to the panel, using the screws that you removed earlier. Firmly tighten all four screws.

The cable that connects the video fader to the V-4 may become disconnected if you pull strongly when unfastening the video fader panel. Please use caution when pulling the T-bar away from the panel.

If you attempt to rotate the vide fader panel further than 90 degrees, the internal cable may be damaged. Note the location of the triangle symbols, and do not rotate the video fader panel further than 90 degrees.

To remove the screws, use a screwdriver that matches the screw heads, and work carefully. If the screw heads become damaged, you will be unable to fasten the video fader in place.

Troubleshooting

If you suspect a malfunction, please check your system once again, taking note of the points listed below. If it still does not function correctly, contact an Edirol Service Center or the dealer where you purchased the unit.

Operating the video fader does not switch the image

If the same image is being input to channels A and B, operating the T-bar will not produce any change in the output image. You must input different images into channels A and B.

Operating the transformer buttons (TRANSFORMER) does not switch the image

With the factory settings, when the memory dial is set to 1, these buttons will "cut" between images. Check the position of the memory dial.

No image is output even though you play back the source device

Make sure that the output fade dial is set to the center position (green LED lit). With the factory settings, turning the dial toward the left will fade to black, and turning it toward the right will fade to white. If the dial is set all the way to left or right, no image will be output. Also make sure that the input select setting is correct.

Turning the control dial does not change the effect

Not all effects have parameters that can be modified by the control dial. If you have selected an effect whose parameter can be modified by the control dial, the channel A/B effect button will blink. If the button is only lit (not blinking), the control dial will not affect the parameter.

Image does not switch (effect not applied) in time with the BPM

Did you press the BPM sync button (BPM SYNC)? The BPM sync button (BPM SYNC) must be pressed if you want to switch the image or apply an effect in time with the BPM.

Image does not switch (effect does not apply) in time with TAP

Did you press the BPM sync button (BPM SYNC)? The BPM sync button (BPM SYNC) must be pressed if you want to use the TAP button to switch the image or apply an effect.

Operating the video fader does not switch the image in the expected direction

It is possible that if you detached the video fader to reposition it by 90 degrees, the internal connector may have been pulled out and re-inserted in the opposite orientation. Detach the video fader with its mounting plate, and try reinserting the connector in the opposite orientation.

    C["Video images"] --> B
    D["Large display (plasma)"] --> B
    E["Projector"] --> B
    B --> F["Preview"]
    B --> G["Video image"]

Advantages of using the V-4

• Two images (two live images, or live video + recorded video) can be mixed
• Use picture-in-picture to display two screens simultaneously

* For details on switching images, refer to p. 23.

* For details on using picture-in-picture, refer to p. 26.

Using the V-4 at a concert or VJ performance

You can project the output image on a large screen such as the stage backdrop, and create a video performance that follows the music. Images from the DV-7PR can be mixed with multiple live images.

graph TD
    A["Live source"] --> B["Preview"]
    C["DV-7PR Video output"] --> B
    B --> D["Projector (1)"]
    B --> E["Projector (2)"]

Advantages of using the V-4

• Use BPM/TAP to switch images in time with the music
• Use numerous effects such as mirror, strobe, or colorize

* For details on using BPM/TAP, refer to p. 37.
* For details on using strobe, refer to p. 34.
* For details on using colorize, refer to p. 32.

Using the V-4 at a presentation

You can use the V-4 to switch between live images and VTR/DVD output, or add images/text from a personal computer.

* If you are using a personal computer that does not have a video output, you will need to use a scan converter to convert the computer's VGA output into a video signal.

• Use luminance key to superimpose text or graphics on the image
• Easy operation in Presentation mode

* For details on using picture-in-picture, refer to p. 26.

* For details on using luminance key, refer to p. 28.

* For details on Presentation mode, refer to p. 68.

Using BGV output with a musical performance (example of using V-LINK)

Background video (BGV) can be controlled while you play a musical instrument. You can control images without affecting the normal capabilities of the instrument. In particular if you are using a device that supports Roland/Edirol V-LINK () V-LINVless a single button to quickly and easily make settings for controlling images.

    D["Preview"] --> B
    B --> E["Projector (1)"]
    B --> F["Projector (2)"]
    B --> G["MIDI control"]
    G --> H["Audio Player"]

Advantages of using the V-4

• When used in conjunction with the DV-7PR, a single instrument can control the live video and the video from the DV-7PR
  • Video effects can be turned on/off from the musical instrument
• If you are using a V-LINK compatible device, MIDI settings can be made very simply

* For details on controlling the V-4 from an external device, refer to p. 57.

■Decimal and hexadecimal conversion table

(The letter "II" follows numbers in hexadecimal notation.)

MIDI uses hexadecimal notation in 7-bit units to indicate data values and addresses and sizes within an exclusive message. Hexadecimal and decimal numbers correspond as follows.

Deci	Hexa	Deci	Hexa	Deci	Hexa	Deci	Hexa

* Decimal expressions used for MIDI channel, bank select, and program change are 1 greater than the decimal value shown in the above table.

* Hexadecimal values in 7-bit units can express a maximum of 128 levels in one byte of data. If the data requires greater resolution, two or more bytes are used. For example, a value indicated by a hexadecimal expression in two 7-bit bytes "aa bb" would be "aa x 128 + bb."

What is the decimal equivalent of 5AH?

From the above table, 5AH = 90.

What is the decimal expression of the hexadecimal

expression in two 7-bit bytes "12H 34H"?

From the above table, 12H = 18, and 34H = 52. Thus,

18 × 128 + 52 = 2356

■Examples of MIDI messages

92H 33H 5F

9n is the Note-on status, and n is the MIDI channel number.

2H = 2, 3EH = 62, and 5FH = 95. Thus, this is a Note-on message of MIDI CH= 3, note number 62 (note name D4), and velocity 95.

CEH 49H

CnH is the Program Change status, and n is the M1D1 channel number.

EH = 14, and 49H = 73. Thus, this is a Program Change message of MIDI CH= 15, program number 74 (in the GS sound map, Flute).

EAH 00H 28H

EnH is the Pitch Bend Change status, and n is the MIDI channel number.

The second byte (00H=0) is the lower byte of the pitch bend value, and the third byte (28H=40) is the upper byte. Since the pitch bend value is a signed value with 40H 00H (=64 x 128 + 0 = 8192) corresponding to 0, the pitch bend value in this case is:

28H 00H - 40H 00H = 40 x 128 + 0 - (64 x 128 + 0) = 5120 - 8182 - -3072

If the Pitch Bend Sensitivity is set to two semitones, a pitch change of -8192 (00II 00II) would change the pitch by -200 cents, so in this case, a pitch bend of -200 x (-3072) / (-8192)

= -75 cents is being designated on MIDI channel 11.

■Exclusive message examples and checksum calculation

Roland exclusive messages (RQ1, DT1) contain a checksum following the data (after F7), which can be used to check whether the message was received correctly. The checksum value is derived from the address and data (or size) of the transmitted exclusive message.

- Calculating the checksum ('H' is appended to hexadecimal numbers)

The checksum is a value that produces a lower 7 bits of zero when the address, size, and checksum itself are summed. If the exclusive message to be transmitted has an address of aaH bbH ccH and the data is ddH ccH, the actual calculation would be as follows:

aa + bb + cc + dd + ee = sum

sum / 128 = quotient ÅEremainder

128 - remainder = checksum

Assigning Modulation as the control change that controls the transition effect time for the Tx/Rx Setting

From the "Parameter address map," the Tx/Rx Setting transition effect time has a start address of 01H 10H 00H, and the Modulation control change has a parameter value 01H. Thus,

F0H 41H 10H 00H 5BH 12H 01H 10H 00H 01H ??H 7FH

(5) Command ID (DT1) (6) Address

(7) Data (8) Checksum

(9) EOX

Next, we calculate the checksum.

01H + 10H + 00H + 01H = 1 + 16 + 0 + 1 = 18 (sum)

18 (sum) / 128 = 0 (quotient) ÅE18 (remainder)

Checksum = 128 - 18 (remainder) = 110 = 6EH

Thus, the message to be transmitted is F0H 41H 10H 00H 5BH 12H 01H 10H 00H 01H 6EH 7FH
