Re: Toggle Arm button On and Off in Ableton


I've used MIDI to control the ARM buttons for a long time on my UnO 1 FCB, and it works fine.  If you're using a Note message, Ableton will ignore the Note Off (Velocity zero), because if it didn't, using a keyboard key to control it would be impossible - it would just toggle off when you press the note, and back on again when you release it (or vice-versa).  However, it won't toggle by itself when you send two identical CC messages.  You have to do as EJ Sheldon describes and send a 127 to turn on, and a 0 to turn off.
