Different Operations Depending on Part Mode

Each Part Mode (see 12.1 "About the Part Mode"), which is the sound source operational mode, has different
messages for performing operations upon receipt. Each message is explained in the applicable message sections of
this document.

Channel Message

Receive Channel

The channel number of Channel messages received by each part is in accordance with each part's receive channel
setting, which is configured on this Model. Turning off the setting disabled Channel message receipt for that part.
The MIDI Channel of messages that can change DSP settings is determined by the Global Channel, which is
described under "10.7 MIDI Channel Number".
6

Send Channel

Basically, the MIDI Channel of the Channel message that is sent when play data or parameter setting is changed
is the value that corresponds to the part that is playing or the parameter that was changed. When the performance
part or part for which the parameter setting is changed is Part 1, however, the value depends on the Transpose/
Function Keyboard Channel value.
The MIDI Channel of the message that is sent when the DSP setting is changed depends on the Global Channel,
which is described under "10.7 MIDI Channel Number".
