43 MIDI Messages
Program Change
Selecting a sound causes the RE-220 to transmit a Program Change message, unless
transmission of program messages has been disabled (see Page 33). Similarly, the RE-220
recognizes these messages, unless the reception has been disabled. Refer to page 46 for
Program Numbers of the RE-220 sounds.
General MIDI On / Off Message
The RE-220 recognizes the General MIDI On/Off messages received at the MIDI In port, and
transmits the messages when GM On/Off parameter in the MIDI/Pref menu is changed. The
form of General MIDI On/Off messages is as follows
GM On
F0 7E nn 09 01 F7
nn = device ID ( 00 - 7F; 7F = Broadcast)
GM Off
F0 7E nn 09 02 F7
nn = device ID ( 00 - 7F; 7F = Broadcast)
** GM On/Off messages are System Exclusive Messages.
