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 num- ber 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 con- tain tone data within the range of 0 to 127.

A PROGRAM CHANGE message is sent out through this keyboard’s MIDI OUT terminal whenever you manually change its tone num- ber. Receipt of a PROGRAM CHANGE message from an external ma- chine changes the tone setting of this keyboard.

NOTE

This keyboard supports 128 tones in the range 0 to 127. However, Chan- nel 10 is a percussion-only channel, and Channels 0, 8, 16, 24, 25, 32, 40, 48, and 62 correspond to the nine drum set sounds of this keyboard.

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 it can receive such data.

CONTROL CHANGE

This message adds effects such as vibrato and volume changes ap- plied 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 send or received using CON-

TROL CHANGE.

*RPN stands for Registered Parameter Number, which is a special control change number used when combining multiple control changes. The parameter being controlled is selected using the con- trol values of control numbers 100 and 101, and then settings are made using the control values of DATA ENTRY (control numbers 6 and 38).

This keyboard uses RPN to control this keyboard’s pitch bend sense (pitch change width in accordance with bend data) from another external MIDI device, transpose (this keyboard’s overall tuning adjusted in halftone units), and tune (this keyboard’s overall fine tuning).

NOTE

Sustain (control number 64), sostenuto (control number 66), and soft (con- trol number 67) effects applied using the foot pedal are also applied.

ALL SOUND OFF

This message forces all sound being produced over the current chan- nel to turn off, regardless of how the sound is being produced.

ALL NOTES OFF

This message turns off all note data sent from an external device and currently being sounded on the channel.

Any notes being sustained using a sustain pedal or sostenuto ped- al continue to sound until the next pedal off.

RESET ALL CONTROLLERS

This messages initializes pitch bend and all other control changes.

SYSTEM EXCLUSIVE*

This message is used to control system exclusives, which are tone fine adjustments that are unique to a particular machine. Originally, system exclusives were unique to a particular model, but now there are also universal system exclusives that are applicable to machines that are different models and even produced by different manufac- turers.

The following are the system exclusive messages supported by this keyboard.

GM SYSTEM ON ([F0][7E][7F][09][01][F7])

GM SYSTEM ON is used by an external machine to turn on this key- board’s GM system. GM stands for General MIDI.

GM SYSTEM ON takes more time to process than other messages, so when GM SYSTEM ON is stored in the sequencer it can take more than 100msec until the next message.

GM SYSTEM OFF ([F0][7E][7F][09][02][F7])

GM SYSTEM OFF is used by an external machine to turn off this key- board’s GM system.
