z
Active Sensing
Status
FEH
* When the unit receives active sensing, the unit status changes to observe the
message intervals. In this status, the unit executes receiving error process if a
message interval exceeds 400 msec. Then the unit returns to status of no interval
observation.
* These are not received when “MIDI Rx SOURCE” is set to “USB.”
z
Timing Clock
Status
F8H
* When “MIDI Rx TEMPO CLOCK” is set to “ON,” BPM SYNC synchronization is performed.
z
Start
Status
FAH
* When “MIDI Rx TEMPO CLOCK” is set to “ON,” the start of the BPM SYNC beat is set.
z
Continue
Status
FBH
* When “MIDI Rx TEMPO CLOCK” is set to “ON,” the start of the BPM SYNC beat is set.

F0H:
Status of the system exclusive message
ii= ID number:
This is to specify the manufacturer of the product that
generates the message. The manufacture ID of Roland is 41H.
The ID numbers of 7EH and 7EF are the expansion of MIDI
standard and used as universal non-realtime message (7EH) and
universal realtime message (7FH).

Data Request 1 (RQ1)
This is the message to request of “send data” to the connected device. Specify data
type and amount using address and size. When this is received, the unit sends the
requested data as “Data Set 1 (DT1)” message in case the unit is in status where the
sending of data is possible and requested address and size are appropriate. If not, the
unit sends nothing.
