Midi Implementation - Roland Edirol PCR-1 Owner's Manual

MIDI implementation

1. Receive data
■System exclusive messages
●Universal non-realtime system exclusive message
❍Identity request message
Status Data byte
F0H 7EH, dev, 06H, 01H
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-1)
01H Sub ID #1 (PCR-1)
F7H EOX (End of Exclusive)
●Data transmission
The PCR-1 can use Bulk Dump (p. 119) to transfer its internal Memory sets (p. 100).
❍Data Set 1 DT1 (12H)
These messages transmit the actual data, and are used to transfer data settings to a
device.
Status Data byte
F0H 41H, 10H, 00H, 62H, 12H,
aaH, ddH, ...eeH, sum
Byte Explanation
F0H Exclusive status
41H ID number (Roland)
10H Device ID (For the PCR-1, fixed at 10H)
00H Model ID #1 (PCR-1)
62H Model ID #1 (PCR-1)
12H Command ID (RQ1)
aaH Address
ddH Data

F7H EOX (End of Exclusive)
* 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. 119).
* 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-1 lets you assign any channel voice message to any controller and transmit it.
Status
●Note off
F7H
Status
9nH
n = MIDI channel number:
kk = note number:
* Transmitted when you release a key in Play mode.
●Note on
Status
9nH
n = MIDI channel number:
kk = note number:
vv = note on velocity:
* Transmitted when you push a key in Play mode.
Status
●Polyphonic key pressure
F7H
Status
AnH
n = MIDI channel number:
kk = note number:
vv = key pressure:
●Control change
Status
BnH
n = MIDI channel number:
cc = controller number:
vv = control value:
❍Bank Select (Controller number 0, 32)
Status
BnH
BnH
n = MIDI channel number:
mm = Bank number MSB:
ll = Bank number LSB:
* Transmitted in Bank mode.
❍Modulation (Controller number 1)
Status
BnH
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.
