I also thought that midi track parameters would be scene-assignable. when i first saw the scene/crossfader concept it seemed so natural that i just started mapping synth controls like crazy.. it kinda sucks now to find out my setup is garbage.
Concerning midi oveflow: somebody made a good point about 3 LFOs modulating parameters simultaneuosly..
there is definately room for SOME scene morph assignments...
maybe if you sacrifice a midi track you could make 6 parameters available for scene assignment...?
It is really the ONE thing that this damn feature monster doesnt have..
