MIDI-guitar (was: Touch Switches/TS instruments )

[Theo]

This was just one of my notorious wild ideas.
(like using a exor function to create a conctant gap bedween two overlapping
pulses, did not work due to jitter)
Have to learn to sit on them a while before yelling them out to the world.
That way I may put them in a form that could be actually usefull.

I'll come back on this one later.

Cheers Theo
