You can make detailed adjustments to MIDI settings.
MIDI Transmit/Receive Channel Selection
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.
Setting the Transmit Channel
While holding down the [DEMO] button, press and hold the [METRONOME ON/OFF] button,
then press one of the C1–E2 keys.
Setting the Receive Channel
While holding down the [DEMO] button, press and hold the [METRONOME ON/OFF] button,
then press one of the C4–F5 keys.
NOTE
In Dual, 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.”
NOTE
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 music computer or
sequencer.
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 music
computer or sequencer.
NOTE
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.
NOTE
Data for the demo song and piano preset
songs cannot be transmitted via MIDI.
Local Control ON/OFF
“Local Control” refers to the fact that, normally, the keyboard of the instrument controls its internal tone generator, allowing the internal 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 MIDI OUT terminal when notes are played on the keyboard. At the same time, the internal tone generator responds to MIDI information received via the MIDI IN terminal.
While holding down the [DEMO] button, press and hold the [METRONOME ON/OFF] button,
then press one of the A#5 key. Pressing the A#5 key repeatedly toggles between Local Control On
and Off.

MIDI Functions
Program Change ON/OFF
Normally the instrument will respond to MIDI program change numbers received from an external keyboard or other MIDI device,
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 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 the
instrument without affecting the external MIDI device.
While holding down the [DEMO] button, press and hold the [METRONOME ON/OFF] button,
then press one of the B5 key. Pressing the B5 key repeatedly toggles between Program Change On
and Off.

For information on program change numbers for each of the Voices of the instrument, refer to page 4.

Default setting: ON
Control Change ON/OFF
Normally the instrument will respond to MIDI control change data received from an external MIDI device or keyboard, 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 an external MIDI device.
While holding down the [DEMO] button, press and hold the [METRONOME ON/OFF] button,
then press one of the C6 key. Pressing the C6 key repeatedly toggles between Control Change On
and Off.
