1. Receive data
■System exclusive messages
●
Universal non-realtime system exclusive message
❍Identity request message
Status Data byte Status
F0H 7EH, dev, 06H, 01H F7H
Byte Explanation
F0H Exclusive status
7EH ID number (Universal non-realtime system exclusive message)
dev Device ID (10 or 7FH (Broadcast))
06H Sub ID #1 (PCR-30/50/80)
01H Sub ID #1 (PCR-30/50/80)
F7H EOX (End of Exclusive)
●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.
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.
●Note on
Status 2nd byte 3rd byte
9nH kkH vvH
n = MIDI channel number: 0H – FH (Ch.1 – 16)
kk = note number: 00H – 7FH (0 – 127)
vv = note on velocity: 01H – 7FH (1 – 127)
* Transmitted when you push a key in Play mode.
●Polyphonic key pressure
Status 2nd byte 3rd byte
AnH kkH vvH
n = MIDI channel number: 0H – FH (Ch.1 – 16)
kk = note number: 00H – 7FH (0 – 127)
vv = key pressure: 00H – 7FH (0 – 127)
●Control change
Status 2nd byte 3rd byte
BnH ccH vvH
n = MIDI channel number: 0H – FH (Ch.1 – 16)
cc = controller number: 00H – 77H
vv = control value: 00H – 7FH
❍Bank Select (Controller number 0, 32)
Status 2nd byte 3rd byte
BnH 00H mmH
BnH 20H llH
n = MIDI channel number: 0H – FH (Ch.1 – 16)
mm = Bank number MSB: 00H – 7FH
ll = Bank number LSB: 00H – 7FH
* Transmitted in Bank mode.
❍Modulation (Controller number 1)
Status 2nd byte 3rd byte
BnH 01H vvH
n = MIDI channel number:0H – FH (Ch.1 – 16)
vv = Modulation depth:00H – 7FH (0 – 127)
* Transmitted by upward/downward operation of the BENDER lever in Play
mode.
