this guy totally rewrote the Mackie Universal Control remote map that exists in Reason.
http://www.jaexx.com/blog/reason-custom ... ap-layout/The remote map, called MJ Enhanced Universal Control, fixes problems like buttons being mapped in the wrong areas, virtually eliminates clip LEDs getting triggered, functions missing entirely (like the EQ Q knobs) while adding enhancements and new features
This mapping is for: Mackie MCU, MCU Pro or Behringer X-Touch
and best of all it is for free.
