ENGLISH Program Change ON/OFF Normally this instrument will respond to MIDI program change numbers received from an external keyboard or other MIDI device, causing the correspondingly-numbered voice to be selected on the corresponding channel (the keyboard voice does not change). This instrument will normally also send a MIDI program change number whenever one of its voices is selected, causing the correspondingly-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 this instrument without affecting the external MIDI device. Procedure While holding down the [DEMO/SONG] and [PIANO/VOICE] buttons simultaneously, press the C 6 key. Pressing the C 6 key repeatedly toggles between Program Change On and Off. C 6 For information on program change numbers for each of this instrument's voices, refer to page 40 in the MIDI Data Format section. The highest key Control Change ON/OFF MIDI Control Change data refers to MIDI information related to performance expression (such as damper pedal information). You can transmit MIDI Control Change data from this instrument to control the operation of the connected MIDI device. (For example, if you operate this instrument's damper pedal, this instrument will transmit MIDI Control Change data.) On the other hand, MIDI performance data of this instrument will respond to MIDI Control Change data received from the connected MIDI device. (At this time, the voice you are playing on the keyboard will not be affected by the Control Change data.) The ability to transmit and receive MIDI Control Change data is sometimes very useful. Turn Control Change On if it is convenient for you to have this capability. Turn Control Change Off if you rather prefer not to have this capability. For information on control changes that can be used with this instrument, refer to the MIDI Data Format on page 40. Procedure While holding down the [DEMO/SONG] and [PIANO/VOICE] buttons simultaneously, press the D6 key. Pressing the D6 key repeatedly toggles between Control Change On and Off.
