Kurzweil Mark-Pro 3i Owner's Manual page 41

Volume: CC #7,39
The Mark Pro 3i recognizes Volume messages, which control the overall volume of the sound on
the MIDI channel on which they are sent. Controller 7 can be used by itself, or if a finer degree
of control is desired, controller 39 can be used in conjunction with it.
Pan: CC #10,42
The Mark Pro 3i recognizes Pan messages, which control the location of the sound in the stereo
field on the MIDI channel on which they are sent. Controller 10 can be used by itself (a value of
0 is hard left, 64 is centered, and 127 is hard right), or if a finer degree of control is desired,
controller 42 can be used in conjunction with it.
Expression: CC #11,43
The Mark Pro 3i recognizes Expression messages, which also regulate the volume of the sound
on the MIDI channel on which they are sent between a minimum of 0 and a maximum of the
current Volume setting. Controller 11 can be used by itself, or if a finer degree of control is
desired, controller 43 can be used in conjunction with it.
Sustain, Sostenuto, and Soft Pedals: CC #64, 66, 67
The right, center, and left pedals transmit MIDI controller message 64 (Sustain), 66 (Sostenuto),
67 (Soft), respectively. The Mark Pro 3i also recognizes these messages. A value of 0 is OFF and a
value of 127 is ON.
All Sound Off, Reset All Controllers: CC#120, #121
The Mark Pro 3i recognizes the All Sound Off message (CC #120) which silences the instrument
and the Reset All Controllers message (CC #121) which resets all controllers to their default
values.
