[sdiy] quadraphonic panning (probably OT at this point)

[Amos]

OT: This sounds like a set-up for which Audiomulch (q.v:
http://www.audiomulch.com) might also be ideally suited.  Responds
very well to esoteric control schemes and can be run at quite a low
latency if you have the hardware for it.  Also very nice to set up for
multi-multi-channel I/O.
