■System Realtime Message
●Timing Clock
Status
F8H
* This message will be received if the Clock Source parameter (Edit:System Basic:Clock
Source) is MIDI.
●Active Sensing
Status
FEH
*When Active Sensing is received, the unit will begin monitoring the intervals of all
further messages. While monitoring, if the interval between messages exceeds 420 ms,
the same processing will be carried out as when All Sounds Off, All Notes Off and Reset
All Controllers are received, and message interval monitoring will be halted.
■System Exclusive Message
Status Data byte Status
F0H iiH, ddH, ......,eeH F7H
F0H: System Exclusive Message status
ii = ID number: an ID number (manufacturer ID) to indicate the manufacturer whose
Exclusive message this is. Roland’s manufacturer ID is 41H.
ID numbers 7EH and 7FH are extensions of the MIDI standard;
Universal Non-realtime Messages (7EH) and Universal Realtime
Messages (7FH).
dd,...,ee = data: 00H - 7FH (0 - 127)
F7H: EOX (End Of Exclusive)
Of the System Exclusive messages received by this device, the Universal Non-realtime
messages and the Universal Realtime messages and the Data Request (RQ1) messages and
the Data Set (DT1) messages will be set automatically.

●Data Transmission
This instrument can use exclusive messages to exchange many varieties of internal settings
with other devices.
The model ID of the exclusive messages used by this instrument is 00H 5FH.
❍Data Request 1 RQ1 (11H)
This message requests the other device to transmit data. The address and size indicate the
type and amount of data that is requested.
When a Data Request message is received, if the device is in a state in which it is able to
transmit data, and if the address and size are appropriate, the requested data is transmitted
as a Data Set 1 (DT1) message. If the conditions are not met, nothing is transmitted.

* The size of data that can be transmitted at one time is fixed for each type of data. And
data requests must be made with a fixed starting address and size. Refer to the address
and size given in “Parameter Address Map” (p. 109).
