2. Transmit data■Channel voice messages

In addition to the channel voice messages that can be transmitted in each mode, the PCR-30/50/80 lets you assign any channel voice message to any controller and transmit it.

●Note off

Status

2nd byte

3rd byte

9nH

kkH

00H

n = MIDI channel number:0H – FH (Ch.1 – 16) kk = note number: 00H – 7FH (0 – 127)

*Transmitted when you release a key in Play mode.

●Data transmission

The PCR-30/50/80 can use Bulk Dump (p. 177) to transfer its internal memory set data (p. 164).

❍Data Set 1 (DT1)

These messages transmit the actual data, and are used to transfer data settings to a device.

*The amount of data that can be transmitted at once is fixed for each type of data. Data that does not have the specified starting address and data size will not be received. Refer to the explanation in 3. Bulk Dump (p. 177).

*There must be an interval of at least 40 ms between each exclusive message that is sent.

*Also, you must leave an interval of at least 500 ms after transmitting one set of bulk dump data.
