hello. i would like to open vst uis with midi CCs. here is a way things could work:
this would work by current selected track (track where the cursor is).
in the midi mappings you would have something like this:
first VSTfx - cc101
second VSTfx - cc102
third VSTfx - cc103
fourth VSTfx - cc104
32 of this would be enough
this would work a bit like the cc parameter automation per track that renoise already has.
the instruments would work a bit different. it wouldnt depend on the selected track. each intrument slot would have its own cc.
it would be also cool to have a midi cc that would open the ui of the current selected intrument.
