MIDI settings.

For more information about MIDI, see the

“About MIDI” section (page 48).

F7.1: MIDI Transmit 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 MIDI data.

Setting range: 1–16, OFF (not transmitted)

Default setting: 1

F7.2: MIDI 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 spec-

ify the channel on which the instrument receives MIDI

data.

Setting range: ALL, 1&2, 1–16

Default setting: ALL

F7.3: Local Control ON/OFF

“Local Control” refers to the fact that, normally, the

instrument keyboard 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

keyboard 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 key-

board. At the same time, the internal tone generator

responds to MIDI information received via the MIDI IN

terminal.

Setting range: ON/OFF

Default setting: ON

F7.4: 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 correspondingly num-

bered 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 corre-

spondingly 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 affect-

ing the external MIDI device.

Setting range: ON/OFF

Default setting: ON

SHORTCUT:

You can jump directly to the metronome functions by press-

ing the [TEMPO/FUNCTION] button while holding the [METRO-

NOME] button.

F7. MIDI Functions

• In Dual, Voice 1 data is transmitted on its speciﬁed channel. In

Split, right voice data is transmitted on its speciﬁed channel. In

Dual, Voice 2 data is transmitted on the next greater channel num-

ber relative to the speciﬁed channel. In Split, left voice data is

transmitted on the next greater channel number relative to the

speciﬁed channel. In either case, no data is transmitted if the

transmit channel is set to “OFF.”

• Song data is not transmitted via the MIDI connections. However,

channels 3–16 of External songs will be transmitted via the MIDI

connections depending on the Song Channel Selection setting

(page 43).

NOTE

• ALL:

“Multi-timbre” Receive. This allows simultaneous reception of dif-

ferent 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.

•Program change and other like channel messages received will

not affect the instrument’s panel settings or the notes you play on

the keyboard.

For information on program change numbers for each of the instru-

ment’s voices, refer to MIDI Data Format page 62.
