System Realtime Message
Active Sensing
When FC-300 receives Active Sensing, it measures time intervals
between incoming messages. If the subsequent message will not come
within 400 msec after the previous one, FC-300 turns off Active
Sensing for a period and stops measuring message intervals.
System Exclusive Message
System Exclusive messages that the FC-300 can receive are Data
Request (RQ1) and Data Set (DT1).
For a detailed explanation about Data Request (RQ1) and Data Set
(DT1), refer to
“Roland System Exclusive Messages”
(p. 59) and
“3. Exclusive Communications”
(p. 64).

ii ID Number: The ID Number (manufacturer’s ID) is
used to distinguish one manufacturer’s System Exclu-
sive messages from another. Roland’s manufacturer ID
is 41H. ID Numbers 7EH and 7FH are used as Universal
Non-realtime messages (7EH), and Universal Realtime
message (7FH) for extending the MIDI standard.
