P-115  MIDI Reference

MIDI Functions

You can make detailed adjustments to MIDI settings.

In Dual, Split or Duo, Voice 1 data is 
transmitted on its specified channel and 
Voice 2 data is transmitted on the next 
greater channel number relative to the 
specified channel. In this case, no data is 
transmitted if the transmit channel is set 
to “OFF.”

ALL:
“Multi-timbre” Receive. This allows 
simultaneous reception of different parts 
on all 16 MIDI channels, enabling the 
instrument to play multi-channel song 
data received from a computer.
1+2:
“1+2” Receive. This allows simultaneous 
reception on channels 1 and 2 only, 
enabling the instrument to play 1 and 2 
channel song data received from a com-
puter.

Program change and other like channel 
messages received will not affect the 
panel settings of the instrument  or the 
notes you play on the keyboard.

Data for the Demo Songs and Preset 
Songs cannot be transmitted via MIDI.

In any MIDI control setup, the MIDI channels of the transmitting and receiving devices must be matched 
for proper data transfer.
This parameter enables you to specify the channel on which the instrument transmits or receives MIDI 
data.

STYLE] button, then press one of the E0–G

#1 keys.

STYLE] button, then press one of the A

#1–D#3 keys.

“Local Control” refers to the fact that, normally, the keyboard of the instrument controls its internal tone generator, allowing the inter-
nal voices to be played directly from the keyboard. This situation is “Local Control On,” since the internal tone generator is controlled 
locally by its own keyboard. Local control can be turned OFF, however, so that the the keyboard of the instrument does not play the 
internal voices, but the appropriate MIDI information is still transmitted via the [USB TO HOST] terminal when notes are played on 
the keyboard. At the same time, the internal tone generator responds to MIDI information received via the [USB TO HOST] terminal.

Default setting: ON

While holding down the [METRONOME/RHYTHM] button, press and hold the [PIANIST 
STYLE] button, then press the D6 key. Pressing the D6 key repeatedly toggles between Local Con-
trol On and Off.
