The Model ID of the series to which the Instrument belongs is shown by two consecutive bytes (MSB, LSB).

(PX-200/PX-320/PX-800/AP-500/PX-120/PX-720/AP-200 Model ID MSB = 15H, LSB = 01H)

16.3.4 dev : MIDI Device ID 00H-7FH

The contents of this field in a received message are compared with the Model's MIDI Device ID, and receipt of the incoming

message is allowed only when the two IDs match. The default value for this field is 10H. When a message containing

7FH is received, receipt of the message is always allowed, regardless of the Instrument's ID setting.

ID of the MIDI System Exclusive Message must be set to 7FH before it is sent.
