I personnally think that as soon as a uP is involved in a
schemo, the thing has to be MIDI compatible.
So why not switching between waveforms via MIDI events, use
controlers to cross-fade waveforms and trigger waveform
processing...

Don't get me wrong : this idea is not expanding beyond control.
It only takes a few components to make a digital module MIDI
compatible. And a few sub-routines allow to receive/send MIDI
data. Magazines and books are full of such ideas...
