Yamaha P-105 Midi Reference - Page 3

MIDI Functions Program Change ON/OFF Normally the instrument will respond to MIDI program change numbers received from a computer, causing the same numbered voice to be selected on the corresponding channel (the keyboard voice does not change). The instrument 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 computer if the computer 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 instrument without affecting the computer. While holding down the [DEMO/SONG] button, press and hold the [METRONOME/RHYTHM] button, then press the D#6 key. Pressing the D#6 key repeatedly toggles between Program Change On and Off. NOTE For information on program change numbers for each of the Voices of the instrument, refer to page 5. NOTE D#6 Default setting: ON Control Change ON/OFF Normally the instrument will respond to MIDI control change data received from a computer, 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 instrument 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 pedal of the instrument and other controls can be operated without affecting a computer. While holding down the [DEMO/SONG] button, press and hold the [METRONOME/RHYTHM] button, then press the E6 key. Pressing the E6 key repeatedly toggles between Control Change On and Off.
