ENGLISH MIDI Functions Program Change ON/OFF Normally the P-70 will respond to MIDI program change numbers received from an external keyboard or other MIDI device, causing the same numbered voice to be selected on the corresponding channel (the keyboard voice does not change). The P-70 will normally also send a MIDI program change number whenever one of its voices is selected, causing the same numbered voice or program to be selected on the external MIDI device if the device is set up to receive and respond to MIDI program change numbers. This function makes it possible to cancel program change number reception and transmission so that voices can be selected on the P-70 without affecting the external MIDI device. While holding down the [DEMO/SONG] and [GRAND PIANO/VOICE] buttons, press the C#6 key. Pressing the C#6 key repeatedly toggles between Program Change On and Off. C#6 C7 NOTE For information on program change numbers for each of the P-70's voices, refer to MIDI Data Format on page 27. Default setting: ON Control Change ON/OFF Normally the P-70 will respond to MIDI control change data received from an external MIDI device or keyboard, causing the voice on the corresponding channel to be affected by pedal and other "control" settings received from the controlling device (the keyboard voice is not affected). The P70 also transmits MIDI control change information when the pedal or other appropriate controls are operated. This function makes it possible to cancel control change data reception and transmission so that, for example, the P-70's pedal and other controls can be operated without affecting an external MIDI device. While holding down the [DEMO/SONG] and [GRAND PIANO/VOICE] buttons, press the D6 key. Pressing the D6 key repeatedly toggles between Control Change On and Off. D6 C7 NOTE For information on control changes that can be used with the P-70, refer to MIDI Data Format on page 27. Default setting: ON P-70 Owner's Manual 23
