[System Exclusive Message]
Status
F0H: System Exclusive
F7H: EOX (End Of Exclusive)
When using Exclusive Messages with the SPD-20, you can bulk dump Patch data, System
data, and Chain data.
For details refer to “Roland Exclusive Message” and paragraph “3. Exclusive
Communications.”
3.Exclusive Communications[General]
SPD-20 can do one-way communications to send and receive parameters for sequence and
setup.
Model ID included in the exclusive message should be 00H 0DH. The device ID code
should be BASIC CH of System. Note that the actual value that set in the device ID field is
smaller by one than the value set at parameter BASIC CH of System.

[Transmission]

The SPD-20 transmit exclusive messages only when MIDI Bulk dump is performed by
panel operation on menu of System function.

[Receive]

When the SPD-20 is using One Way Communication, parameters are received when Bulk
Dump is not executed.
The SPD-20 can receive SPD-11 Patch parameter System Exclusive messages. When this is
done, the SOUND INST Sound parameter is shifted and saved to the SPD-20 Instrument
Number having the same tone as the one received from the SPD-11.
