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-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.
