There should be a MIDI-learn option to assign hardware controls either globally (default) or per selected track.

With this it would be possible to control more parameters with a limited number of knobs.

It would also make it possible to dedicate controls to specific functions.

For example, encoder 1 will always control the cutoff of the oscillator of a selected track.

Because of the changing values, this would be best suited for encoders.

This requires the implementation of MIDI feedback (see separate request) so that the encoder knows the value of the element.
