Hey guys,
I'm trying to create a patch that allows me to control a note's volume (so in essence its attack&velocity) with the modwhl, but use an envelope for the sustain/release stages so the note sustains for as long as the key is held (and gets an env-controlled release)
What I hope to get this way is fully hands-on control of a note's attack and volume --as you would with a theremin for instance-- but without sacrificing polyphony.
This explanation might get a bit hazy, so bear with me:
One possible way I've thought up is for the modwheel to control an oscillator's volume, but only upwards. The idea being that I could hit a note with the modwhl at 0, bring it up to the volume I want, then bring it down to zero again for the next note without the volume going down as well. Then hit another note with the modwhl at zero, bring it up...
I'm thinking this might just be possible with some mseg trickery, but I just can't figure it out.
Alternatively I'd love to use the sustain pedal to 'freeze' a note's volume, but I'm not sure that's currently possible. This way, I don't lose manual vibrato by limiting the modwhl's control to only upwards!
Polyphonic modwhl volume control... any thoughts?

Seems like a tough challenge ... I think velocity and aftertouch are the only per-note MIDI inputs, so to use anything else it would have to get 'frozen' into a particular voice. I can't think of what that something else would be, I tried a few things that didn't work ...
What sort of worked was using an MMap to control oscillator volume, and tweaking that in real-time with the mouse. The MMap's steps don't get captured by the host for automation, so it's definitely a bit of a hack.

Sadly polyphonic aftertouch is a pretty rare feature for midi keyboards to have, and mine (novation) only features the monophonic kind. Which is also a tad jumpy for what I intended, I'm afraid.
Anyway, I've accepted the limits of my controller, and now I'm looking to do this within those limits. Freezing a note at a certain point was what I was thinking as well, and sounds like a really nice solution, if only I could figure out how!
Unless I've missed a clever solution, though, I'm afraid this won't be possible without Urs' help.
