■System realtime messages
●Active Sensing
Status
FEH
*Once an Active Sensing message is received, the system will begin monitoring the interval between all subsequent messages. If there is an interval of greater than approximately 400 ms between messages while monitoring is occurring, the system will perform reception error processing and will then stop monitoring the message interval.
●Timing Clock
Status
F8H
*Used to synchronize BPM SYNC.
●Start
Status
FAH
*Specifies the beginning of the beat for BPM SYNC.
●Continue
Status
FBH
*Specifies the beginning of the beat for BPM SYNC.
■System exclusive messages
Status | Data bytes | Status |
F0H | iiH, ddH,...,eeH | F7H |
F0H: System Exclusive Message status
ii= ID number: An ID number (manufacturer ID) that indicates the manufacturer to which the exclusive message belongs. Roland’s manufacturer ID is 41H. ID numbers 7EH and 7FH are used for Universal
dd, ... ee= data:
F7H: EOX (End Of Exclusive)
●Data Set 1 (DT1)
This is the message that transfers actual data, and is used to specify data for a device.

*For details on setting the address, size, and checksum, refer to “Example of exclusive message and checksum calculation” (p. 95).
*Data that exceeds 256 bytes must be divided into packets of 256 bytes or less for transmission. If a subsequent “Data Set 1” message is transmitted, an interval of at least 20 ms must be left between packets.
