This is my first post here. I made my first useful abstraction and thought it worth sharing. It's a mixer with volume, pan and stereo width controls, mute/solo mode, pre/postfader and 'learn' triggers. Just turn on any 'learn' trigger and move any knob/slider on you MIDI controller, - corresponding slider will follow its movement.
MIDI-learnable mixer channel
Hey, thanks for the idea for "learn" triggers.
I just made an abstraction for this that also allows you to save the learned channel and note/control numbers to a text file (which you can then load later).
