NP-31/NP-11 MIDI Reference

MIDI Functions

You can make detailed adjustments to MIDI settings.

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.”

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.

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 song and piano 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.

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.

“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 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.

Default setting: ON

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.

NP-31/NP-11 MIDI Reference 3

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.

For information on program change num-

bers for each of the Voices of the instru-

ment, refer to page 4.

Default setting: ON

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.

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 key-

board voice is not affected). The instrument also transmits MIDI control change information when the pedal or other appropriate con-

trols 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.

For information on control changes that

can be used with the instrument, refer to

page 4.

Default setting: ON

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.

• When Control Change is turned OFF, Control Change messages

will not be transmitted or received.

• Local on/off, OMNI on/off are not transmitted. (The appropriate note

off number is supplied with “All Note Off” transmission).

• When a voice bank MSB/LSB is received, the number is stored in

the internal buffer regardless of the received order, then the stored

value is used to select the appropriate voice when a program

change message is received.

• Poly mode is always active. This mode will not change when the

instrument receives a MONO/POLY mode message.

4. PROGRAM CHANGE

Data format: [CnH] -> [ppH]

CnH = Program event (n = channel number)

ppH = Program change number

• When program change reception is turned OFF, no program change

data is transmitted or received.

• When you specify a program change as a number in the range of

0–127, specify a number that is one less than the program change

number listed above. For example, to specify program change num-

ber 1, you would specify a value of 0.

• Simultaneously changes the volume of all channels.

• When a MIDI master volume message is received, the volume only

has affect on the MIDI receive channel, not the panel master vol-

ume.

F0H = Exclusive status

7FH = Universal Realtime

7FH = ID of target device

04H = Sub-ID #1=Device Control Message

01H = Sub-ID #2=Master Volume

X = irrelevant

09H = Sub-ID #1=General MIDI Message

01H = Sub-ID #2=General MIDI On

F7H = End of Exclusive

When the General MIDI mode ON message is received, the MIDI

system will be reset to its default settings.

This message requires approximately 50ms to execute, so suffi-

cient time should be allowed before the next message is sent.

8. SYSTEM EXCLUSIVE MESSAGES (XG Standard)

(1) XG Native Parameter Change

Data format: [F0H] -> [43H] -> [1nH] -> [4CH] -> [hhH] -> [mmH] ->

1nH = When received, n=0–F.

When transmitted, n=0.

4CH = Model ID of XG

hhH = Address High

mmH = Address Mid

llH = Address Low

ddH = Data

F7H = End of Exclusive

Data size must match parameter size (2 or 4 bytes).

When the XG System On message is received, the MIDI system

will be reset to its default settings.

The message requires approximately 50ms to execute, so suffi-

cient time should be allowed before the next message is sent.

(2) XG Native Bulk Data (reception only)

Data format: [F0H] -> [43H] -> [0nH] -> [4CH] -> [aaH] -> [bbH] ->

ccH = Check sum

F7H = End of Exclusive

• Receipt of the XG SYSTEM ON message causes reinitialization of

relevant parameters and Control Change values. Allow sufficient

time for processing to execute (about 50 msec) before sending the

NP-31 NP-11 another message.

• XG Native Parameter Change message may contain two or four

bytes of parameter data (depending on the parameter size).

• For information about the Address and Byte Count values, refer to

Table 1 below. Note that the table’s Total Size value gives the size of

a bulk block. Only the top address of the block (00H, 00H, 00H) is

valid as a bulk data address.
