MIDI Channel Selection
The MP25's front panel controls are MIDI enabled. Changes to
front panel controls may be sent via MIDI to audio applications
on the computer. By default, the MP25 uses MIDI channel 1
to send MIDI messages. However, you can change the output
channel number using the MIDI Out control. Some MP25
features may be controlled via MIDI. By default, the MP25 does
not accept MIDI input. However, you can enable MIDI input to
the MP25 by setting the MIDI In channel number.
MIDI Out Controls
All MP25 front panel controls with the exception of the Main
Balance, Main Level, and Zone Level send MIDI output mes-
sages when changed.
• Buttons output a MIDI Note On message when pressed and a
MIDI Note Off message when released.
• Pots and faders output a MIDI control change message when-
ever they change value. The value is a number in the range 0
to 127 (counter-clockwise to clockwise, down to up, or left to
right).
• Switches produce control change messages when they change
value. The following table lists MP25 switches and their con-
trol values.
