Roland MMP-2 MIDI Implementation, Transmitted Data And, Regognized Receive Data, Control Change

MIDI Implementation

Model: MMP-2	The Roland system exclusive messages use device IDs to specify multiple
Version: 1.00	MMP-2 units.
TRANSMITTED DATA AND	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
REGOGNIZED RECEIVE DATA	same as its device ID and 7FH.
	(*1) See “Data Transfer Address Map” (p. 47) section.

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).

The message is used to request the particular information of the MMP-2. The MMP-2 does not transmit the message.

If the MMP-2 received the message and the device ID of the message is same as its device ID or 7FH, the MMP-2 transmits the following Identity Reply message.

The message is used to request data to the MMP-2.

The MMP-2 does not transmit this message.

The MMP-2 transmits the requested data using Data Set(DT1) under following condition when it received the message.

1.The requested address correspond to the specified parameter base address of the MMP-2.

2.The requested size is over 1 byte.

❍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.
