When an Active Sensing message is received, the unit will begin monitoring the interval
at which MIDI messages are received. During monitoring, if more than 420 ms passes
without a message being received, the same processing will be done as when All Sound
Off, All Note Off, and Reset All Controllers messages are received. Then monitoring will
be halted.

This is the ID number (manufacturer ID) that specifies the
manufacturer whose exclusive message this is. Roland’s manufacturer
ID is 41H.ID numbers 7EH and 7FH are defined in an expansion of the
MIDI standard as Universal Non-realtime messages (7EH) and
Universal Realtime Messages (7FH).

Data Request 1 RQ1
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 model ID of the exclusive messages used by this instrument is 00 0BH.
