MIDI Functions

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 NP-

30/YNP-25 transmits or receives MIDI data.

Setting the Transmit Channel

While holding down the [SONG

] and [GRAND PIANO] buttons, press one

of the C1–E2 keys.

Setting the Receive Channel

While holding down the [SONG

] and [GRAND PIANO] buttons, press one

of the C4–F5 keys.

Local Control ON/OFF

“Local Control” refers to the fact that, normally, the NP-30/YNP-25 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 NP-30/YNP-25 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 keyboard. At the same time, the internal tone generator responds to

MIDI information received via the MIDI IN terminal.

While holding down the [SONG

] and [GRAND PIANO] buttons, press the

C6 key. Pressing the C6 key repeatedly toggles between Local Control On and

Off.

In Dual, Voice 1 data is transmit-

ted on its speciﬁed channel and

Voice 2 data is transmitted on the

next greater channel number rela-

tive 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 NP-30/

YNP-25 to play multi-channel

song data received from a music

computer or sequencer.

1+2:

“1+2” Receive. This allows simul-

taneous reception on channels 1

and 2 only, enabling the NP-30/

YNP-25 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 NP-30’s/YNP-25’s

panel settings or the notes you

play on the keyboard.

Data for the demo song and

piano preset songs cannot be

transmitted via MIDI.
