Setting the MIDI Transmit Channel

be matched for proper data transfer. You can specify the channel on which this instrument
transmits MIDI data. To do this, while holding down [GRAND PIANO/FUNCTION], press one
of the A6–B6 keys. The A6 key decreases the value by 1, the B6 key increases the value by
1, and the A#6 key restores the default value (channel 1).
Setting range: 1–16
Default value: 1

The MIDI settings other than the Transmit Channel are set as listed below, and cannot be
changed.
