Midi learn/CC assignment capability for various scalar settings

midi learn function to turn on and off or toggle various settings during performance/playback, and midirecording.

Midi cc 's for expression, program channel to select the expression

Yeah I think we need to go there but as everything is so complex we need to let the dust settle in terms of how exactly features, pages etc will interact and coexist according to user feedback over time. I am feeling Scaler 2.5 will have some Midi Learn and CC functions. Makes sense but not a main priority today. Thanks for feedback.
