Audio Equipment (Figure 2)

Connect the keyboard to a audio equipment using a commercially available connecting cord with a standard plug on one end and two PIN plugs on the other end. Note that the standard plug you connect to the keyboard must be a stereo plug, otherwise you will be able to output only one of stereo channels. In this configuration, you normally set the input selector of the audio equipment to the terminal (usually marked AUX IN or something similar) where the cord from the keyboard is connected. See the user documentation that comes with your audio equipment for full details.

Musical Instrument Amplifier (Figure 8)

Use a commercially available connecting cord to connect the keyboard to a musical instrument amplifier.

NOTE

Be sure to use a connecting cord that has a stereo standard plug on the end you connect to the keyboard, and a connector that provides dual channel (left and right) input to the amplifier to which you are connecting. The wrong type of connector at either end can cause one of the stereo channels to be lost.

When connected to a musical instrument amplifier, set the volume of the keyboard to a relatively low level and make output volume adjustments using the amplifier's controls.

[Connection Example]

NOTE

You can also connect the keyboard's MIDI terminal to a computer or sequencer. See "MIDI" on page E-30 for details.

Sustain jack Terminal

You can connect an optional sustain pedal (SP-2 or SP-10) to the SUS-TAIN JACK terminal to enable the capabilities described below.

This section provides information on performing basic keyboard operations.

To play the keyboard

1. Set the POWER/MODE switch to NORMAL.

2. Use the MAIN VOLUME buttons to lower the keyboard volume.

3. It's always a good idea to set the keyboard volume at a relatively low level before playing.

4. Pressing [] or [] causes the current volume setting to appear on the display. Press [] or [] again to change the setting.

5. Play something on the keyboard.

Selecting a Tone

This keyboard comes with 100 built-in tones. Use the following procedure to select the tone you want to use.

To select a tone

1. Find the tone you want to use in the keyboard's tone list and note its tone number.
2. Press the TONE button.

1. Use the number buttons to input the two digit tone number for the tone you want to select. Example: To select "26 WOOD BASS", input 2 and then 6.

• Now notes played on the keyboard will be played using an acoustical wood bass sound.

NOTES

• Always input both digits for the tone number, including a leading zero (if any). If you input one digit and stop, the display will automatically clear your input after a few seconds.
• You can also increment the displayed tone number by pressing [+] and decrement it by pressing [-] .
  Sound effect tones such as 77 VEHICLE sound best when you keep a keyboard key depressed.

Combination tones

The following describes the two types of combination tones that are available.

Layered Tones (Tone Numbers: 80 through 89)

Example: 80 STR PIANO

This tone layers a strings tone with a piano tone so they both sound when a keyboard key is pressed.

Split Tones (Tone Numbers: 90 through 96)

Example: 90 BASS/PIANO

This tone splits the keyboard so one range is assigned a bass tone and another range is assigned a piano tone.

Percussion sounds

Example: 99 PERCUSSION

This tone assigns various percussion sounds to the keyboard. See the Percussion Assignment List on page A-4 for full details.

Sound Effect Tones

With sound effect tones 77 through 79, the type of sound produced depends on the octave where the key you press is located. When 78 PHONE is selected available sound types are PUSH TONE 1, PUSH TONE 2, RING 1, RING 2, and BUSY SIGNAL.

Polyphony

The term polyphony refers to the maximum number of notes you can play at the same time. The keyboard has 12-note polyphony, which includes the notes you play as well as the rhythms and auto-accompanyment patterns that are played by the keyboard. This means that when a rhythm or auto-accompanyment pattern is being played by the keyboard, the number of notes (polyphony) available for keyboard play is reduced. Also note that some of the tones offer only 6- note polyphony.

• When rhythm or auto accompaniment is playing, the number of sounds simultaneously played is reduced.

Digital Sampling

A number of the tones that are available with this keyboard have been recorded and processed using a technique called digital sampling. To ensure a high level of tonal quality, samples are taken in the low, mid, and high ranges and then combined to provide you with sounds that are amazingly close to the originals. You may notice very slight differences in volume or sound quality for some tones when you play them at different positions on the keyboard. This is an unavoidable result of multiple sampling, and it is not a sign of malfunction.

622A-E-019A

This keyboard automatically plays bass and chord parts in accordance with the chords you finger. The bass and chord parts are played using sounds and tones that are automatically selected to select the rhythm you are using. All of this means that you get full, realistic accompaniments for the melody notes you play with your right hand, creating the mood of an one-person ensemble.

Selecting a Rhythm

This keyboard provides you with 100 exciting rhythms that you can select using the following procedure.

FINGERED

FINGERED provides you with a total of 15 different chord types. The following describes the FINGERED "Accompaniment keyboard" and "Melody keyboard", and tells you how to play a C-root chord using FINGERED.

FINGERED Accompaniment Keyboard and Melody Keyboard

NOTE

The accompaniment keyboard can be used for playing chords only. No sound will be produced if you try playing single melody notes on the accompaniment keyboard.

See the "Fingered Chord Chart" on page A-3 for details on playing chords with other roots.

1: Inverted fingerings cannot be used. The lowest note is the root.
2: The same chord can be played without pressing the 5th G.

NOTES

• Except for the chords specified in note ^11 above, inverted fingerings (i.e. playing E-G-C or G-C-E instead of C-E-G) will produce the same chords as the standard fingering.
• Except for the exception specified in note ^+2 above, all of the keys that make up a chord must be pressed. Failure to press even a single key will not play the desired FINGERED chord.

The Chord Book feature of this keyboard makes it possible for you to look up information about chords quickly and easily. Simply input the name of the chord and the keyboard keys you should press, the fingers you should use, and the notes that make up the chord appear on the display along with the chord name.

What is a chord?

A chord is made up of a root note, upon which is stacked a number of other notes. A variety of different chords can be created by changing the notes stacked onto a root.

Chord Names

Chords are named using upper-case letters from A through G, which indicate the root note of the chord. If the root note is a sharp or flat, the chord itself is sharp or flat. A chord name may also be followed by a degree number or other symbols that indicate certain characteristics about the chord.

C Root	Sharp F# Root	Flat B# Root	Minor Am Root	Sharp Diminished C# root
Seventh G7-Degree Root	Major seventh FM7 Root	Degree	Sus fourth Esus4 Root

Sharps and flats can be referred to using either of the names shown here. The names in the upper row of this illustration are used by this keyboard, because they are the names that are most commonly used in musical notation.

Inverted Forms

There are a number of different ways to play the same chord. A form that is different from the basic form but still produces the same chord is called an "inverted form."

All of the following are C chords.

To Look Up a Chord Using the Chord Book

1. Press the CHORD BOOK button to enter the Chord Book mode.

2. Press the CLEAR button.

• This step is necessary to clear any previously input chord name.

• If the chord name you plan to input is a non-major chord, use the chord specification buttons to specify the chord type.

• Chord types are indicated by the small letters above the chord specifications buttons.

• Non-major chords include minor, seventh, sustained, etc. chords.
• See page E-28 for details on the chord specification buttons.
• Skip step 3 if you want to input a major chord name.

1. Press the accompaniment keyboard key that corresponds to the root note of the chord.

2. A dash appears in place of the chord name if the chord cannot be recognized by the keyboard.
   To specify F^ , for example, press the F key.

3. The key you press is indicated on the graphic keyboard and the corresponding chord sounds.

622A-E-029A

1. Check to make sure that the chord name on the display is the one you want. If it isn't, repeat the above from step 2.
2. If the chord is correct, you can see its fingering on the graphic keyboard. Try playing the chord on the keyboard.

• The fingering that appears on the display is one standard fingering. You can also use other fingerings to match the size of your hands or to make it easier to progress from or to neighboring chords.
• You can also use the [+] and [-] buttons to change the displayed chord name.
• The tone used to sound chords you play on the accompaniment keyboard while using the Chord Book is the same tone used by the accompaniment part of the rhythm that was selected before you entered the Chord Book mode. Depending on the rhythm that was selected, some of the notes that make up a chord may be omitted when you play the chord on the accompaniment keyboard in the Chord Book Mode. This is due to the internal chord conversion function, arrangements, and polyphony limitations. Because of this, you should always play the chords indicated on the display on the melody keyboard (the range that does not have chord names printed above the keys).

NOTES

• Since the chord fingerings that appear on the display are selected to allow chord play within the accompaniment keyboard, inverted chord forms (page E-26) are often suggested. Inverted chord forms are useful to help you learn how to play chord variations that make it possible to move from one chord to another with minimal hand movement. These forms come in handy when using FINGERED Auto Accompaniment play.
• While a chord name is on the display, you can press keys on the accompaniment keyboard to find out the fingerings of the same chord with a different root.
• You can also scroll through chord names using the [+] and [-] buttons.
• Chord fingerings that appear on the display are formed using only the keys within the range of the accompaniment keyboard (leftmost 18 keys).
• Chords that cannot be formed using the keys within this range are not displayed.

Transposing the Keyboard

Transpose lets you raise and lower the overall key of the keyboard in semitone units. If you want to play an accompaniment for a vocalist who sings in a key that's different from the keyboard, for example, simply use transpose to change the key of the keyboard.

To transpose the keyboard

1. Press the TRANSPOSE/TUNE/MIDI button until the transpose screen appears on the display.

1. Use [+] and [-] to change the transpose setting of the keyboard.

Example: To transpose the keyboard five semitones upwards.

NOTES

• The default transpose setting is "0" when keyboard power is turned on.
• If you leave the transpose screen on the display for about five seconds without doing anything, the screen is automatically cleared.
• The transpose setting also affects Auto Accompaniment.
• Playing back a Song Bank tune automatically returns the transpose setting to its standard default of "0".

Tuning the Keyboard

The tuning feature lets you fine tune the keyboard to match the tuning of another musical instrument.

To tune the keyboard

1. Press the TRANSPOSE/TUNE/MIDI button twice to display the tuning screen.

1. Use [+] and [-] to change the tuning setting of the keyboard.

Example: To lower the tuning by 20.

NOTES

• The keyboard can be tuned within a range of -50 cents to +50 cents. *100 cents is equivalent to one semitone.
• The default tuning setting is "00" when keyboard power is turned on.
• If you leave the tuning screen on the display for about five seconds without doing anything, the screen is automatically cleared.
• The tuning setting also affects Auto Accompaniment.
• Playing back a Song Bank tune automatically returns the tuning setting to its standard default of "00".

What is MIDI?

The letters MIDI stand for Musical Instrument Digital Interface, which is the name of a worldwide standard for digital signals and connectors that makes it possible to exchange musical data between musical instruments and computers (machines) produced by different manufacturers. MIDI compatible equipment can exchange keyboard key press, key release, tone change, and other data as messages.

Though you do not need any special knowledge about MIDI to use this keyboard as a stand-alone unit, MIDI operations require a bit of specialized knowledge. This section provides you with an overview of MIDI that will help to get you going.

MIDI Connections

MIDI messages are send out through the MIDI OUT terminal of one machine to the MIDI IN terminal of another machine over a MIDI cable. To send a message from this keyboard to another machine, for example, you must use a MIDI cable to connect the MIDI OUT terminal of this keyboard to the MIDI IN terminal of the other machine. To send MIDI messages back to this keyboard, you need to use a MIDI cable to connect the other machine's MIDI OUT terminal to the MIDI IN terminal of this keyboard.

To use a computer or other MIDI device to record and playback the MIDI data produced by this keyboard, you must connect the MIDI IN and MIDI OUT terminals of both machines in order send and receive data.

MIDI Channels

MIDI allows you to send the data for multiple parts at the same time, with each part being sent over a separate MIDI channel. There are 16 MIDI channels, numbered 1 through 16, and MIDI channel data is always included whenever you exchange data (key press etc.) Both the sending machine and the receiving machine must be set to the same channel for the receiving unit to correctly receive and play data. If the receiving machine is set to Channel 2, for example, it receives only MIDI Channel 2 data, and all other channels are ignored. With this keyboard, messages received over MIDI Channels 1, 2, 3, 4, and 10 can be used for multi-timbre play of up to five different instrument parts. The tone and volume settings for these five channels must be controlled by messages sent from an external device. When sending operation of this keyboard to an external device, Channel 1 should be selected as the MIDI send channel.

General MIDI

General MIDI standardizes MIDI data for all sound source types, regardless of manufacturer. General MIDI specifies such factors as tone numbering, drum sounds, and available MIDI channels for all sound sources. This standard makes it possible for all MIDI equipment to reproduce the same nuances when playing General MIDI data, regardless of the manufacturer of the sound source.

Though the sound source of this keyboard is not General MIDI compatible, you can still connect the keyboard to a computer or other MIDI equipment to playback General MIDI data that is widely available in stores, over computer networks, and from other sources.

NOTES

• General MIDI data made up of a large number of parts may not play correctly on this keyboard.
• You will have most success playing back General MIDI data that has few parts and is made up of data on channels 1, 2, 3, 4, and 10.

Messages

There is a wide variety of messages defined under the MIDI standard, and this section details the particular messages that can be sent and received by this keyboard.

NOTE ON/OFF

This message sends data when a key is pressed (NOTE ON) or released (NOTE OFF).

A NOTE ON/OFF message include a note number (to indicate note whose key is being pressed or released) and velocity (keyboard pressure as a value from 1 to 127). NOTE ON velocity is always used to determine the relative volume of the note. This keyboard does not receive NOTE OFF velocity data.

Whenever you press or release a key on this keyboard, the corresponding NOTE ON or NOTE OFF message is sent by constant velocity from the MIDI OUT terminal.

NOTE

The pitch of a note depends on the tone that is being used, as shown in the Note Table on page A-1. Whenever this keyboard receives a note number that is outside its range for that tone, the same tone in the nearest available octave is substituted.

PROGRAM CHANGE

This is the tone selection message. PROGRAM CHANGE can contain tone data within the range of 0 to 127.

A PROGRAM CHANGE message (0 to 99) is sent out through this keyboard's MIDI OUT terminal whenever you manually change its tone number. Receipt of a PROGRAM CHANGE message from an external machine changes the tone setting of this keyboard (page E-31).

This keyboard can send tone data within the range of 00 to 99 and receive tone data within the range of 0 to 127.

PITCH BEND

This message carries pitch bend information for smoothly sliding the pitch upwards or downwards during keyboard play. This keyboard does not send pitch bend data, but is can receive such data.

CONTROL CHANGE

This message adds effects such as vibrato and volume changes applied during keyboard play. CONTROL CHANGE data includes a control number (to identify the effect type) and a control value (to specify the on/off status and depth of the effect).

The following is a list of data that can be received using CONTROL CHANGE.

Effect	Control Number
VOLUME	7
PAN	10
HOLD1*	64
MODULATION	1

• Pressing the foot pedal causes the sustain effect (HOLD1) to be sent (control number 64).

Changing MIDI Settings

This keyboard lets you change the settings of two MIDI parameters: TONE MAP and KEYBOARD CHANNEL.

To change MIDI parameters

1. Press the TRANSPOSE/TUNE/MIDI button either three or four times to select the parameter you want.

Press the TRANSPOSE/TUNE/MIDI button three times: KEYBOARD CHANNEL

Press the TRANSPOSE/TUNE/MIDI button four times: TONE MAP

Example: To select the TONE MAP parameter.

1. Use [+] and [-] to change the setting of the parameter.

Example: To change the TONE MAP parameter value to "G" (GM).

• If you accidentally go past parameter you want, keep pressing the TRANSPOSE/TUNE/MIDI button until parameter you want reappears on the display.
• If you leave the parameter selection screen on the display for about five seconds without doing anything, the parameter selection screen is automatically cleared.

Parameters and Their Displays

KEYBOARD CHANNEL (Basic Channel) (Default: 01)

This parameter specifies the keyboard MIDI message send channel.

TONE MAP G/N (Default: N)

N: This settings specifies the normal tone map, which allows receipt of a program change value in the range of 0 to 99. Only tones that correspond to the 100 built-in tones of this keyboard can be played, and tone numbers outside this range are ignored.

G: This setting specifies the General MIDI tone map, which allows receipt of a program change value in the range of 0 to 127. Each of the 128 General MIDI tones is automatically assigned to one of the keyboard's 100 built-in tones as shown on page A-1. Select this setting when you want to listen to General MIDI data from a computer or other external equipment.

NOTES

• Playing a Song Bank tune causes all MIDI parameters to revert to their default settings. Also, MIDI messages cannot be received while the keyboard is in the Song Bank Mode.
• Song Bank data cannot be sent as MIDI data.
