[sdiy] Polyphonic AVRSYN?

[Tim Ressel]

Yo,

What I would do is have a main processor that takes in
midi and scans the knobs/switches, and passes commands
to voice processors downstream. The main proc would
keep track of notes a la the old Paia poly stuff. This
way you could add as many voice procs as you
wanted/needed/could afford.

This melds in with something I was wondering about: is
it feasable to string together AVRs to get more
processing power? One proc for oscillators, one for
filters/vcas?

Hmmm ... mayber its time I got back in the game ...
