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)
The System Exclusive Messages received by this device are; Universal Non-
realtime System Exclusive Messages and Data Set 1 (DT1).
