First off, Beatstep Pro is awesome! Its both changed the way I write music and the way I play live, all for the better.
As a feature request, it would be nice to have the ability to send Midi CCs from each sequencers' knobs as an alternate to their default behaviour. This would give the ability to control synth behavior via midi(oscillator wave shape, filter cutoff frequency, device volume, etc.) while at the same time controlling sequencer behaviour (note sequences, default looper behaviour, sequencer length). Can you imagine having an additional 16 CCs per instrument for a total of 64 CCs for the Beatstep pro?
