I like this one a lot, Kim (after the thousands of mails we exchanged, you
still surprise me ;-) :

I just would like to add, that interaction can happen on various levels:

- buttons, controllers
- a characteristic of the effect. For example a good distortion increases
expression, the player can "animate" it with various playing tecniques, so
it turns part of the instrument and does not just "sit there", although it
may just have a on/off control.
- algorithms: the instrument can analize the players expression and
automatically change its parameters. The thouch-wah is a rather primitive
example, at the universities, much more sophisticated ones are developped
(Buchla...). I think in the future, this technology will become much more
The user will have to study or even build the algorithm to learn to
interact with it, as if it was "the second part" of his instrument, still
completely controled by fingers on strings or mouthpiece or whatever.
A future looper may recognize the tempo of the player, maybe automatically
filter out things when the loop becomes overloaded, work out accents...
