Channel Mode Messages (See also Control Change, previous page)
Channel Mode Messages.
This the same code as the Control Change, but implements Mode control and special
message by using reserved controller numbers 120-127. The commands are:
All Sound Off.
When All Sound Off is received all oscillators will turn off, and their volume envelopes
are set to zero as soon as possible.
c = 120, v = 0: All Sound Off
Reset All Controllers. When Reset All Controllers is received, all controller values are
reset to their default values. (See specific Recommended Practices for defaults).
c = 121, v = x: Value must only be zero unless otherwise allowed in a specific
Recommended Practice.
Local Control. When Local Control is Off, all devices on a given channel will respond
only to data received over MIDI. Played data, etc. will be ignored. Local Control On
restores the functions of the normal controllers.
c = 122, v = 0: Local Control Off.
c = 122, v = 127: Local Control On
All Notes Off.
When an All Notes Off is received, all oscillators will turn off.
c = 123, v = 0: All Notes Off (See text for description of actual mode commands).
c = 124, v = 0: Omni Mode Off.
c = 125, v = 0: Omni Mode On
c = 126, v = M: Mono Mode On (Poly Off) where M is the number of channels (Omni
Off) or 0 (Omni On)
c = 127, v = 0: Poly Mode On (Mono Off) (Note: These four messages also cause All
Notes Off)
