F7H EOX (End of System Exclusive message)
The MMP-2 can transfer and receive the internal parameters information using
system exclusive messages, and also can be controlled by the external devices using
system exclusive message.
The MMP-2 can transmit and receive Universal System Exclusive messages, Data
Request (RQ1) and Data set (DT1) as the System Exclusive Message.
❍About Model ID
The Model ID of the MMP-2 is 00H,4EH as for Data Request (RQ1) and Data set
(DT1).
❍About Device ID
System Exclusive messages are not assigned to any particular MIDI channel.
Instead, they have their own special control parameter called device ID.
The Roland system exclusive messages use device IDs to specify multiple
MMP-2 units.
The MMP-2 sends system exclusive messages with the device ID set with “MIDI
Device ID(*1)”, and receives the system exclusive messages whose device ID is
same as its device ID and 7FH.
(*1) See “Data Transfer Address Map” (p. 47) section.
