    Today we can control two parameters via MIDI CC that must be setup in advance. The assignment for expression 1 and expression 2 configure which parameter MIDI CC (and expression) can set a value for either of those.

    The AA needs a command to change which parameter is controlled by MIDI CC (for expression pedals 1 and 2).

    • Ideally this change also holds the last value set for the old parameter unless otherwise changed.
    • This is probably two commands to handle all 140+ assignable params (since CC params are limited to 128 values).
    • OK to limit the rate at which this can be called (e.g., ignore multiple requests received faster than 100ms).
    This really unlocks a lot of value for the AA allowing many deep params to be changed on the fly (more than you could have presets) or varied continuously from a variety of other devices that simply need to send a midi message.
