Ezra,
I think I'm working toward something similar to your work. The key
thing I'm looking at is an algorithmic replacement for what you term
"linear piecewise phase distortions". I think!
I'm avoiding the emulation of Butterworth or Chebyshev filters (no
prejudice against them) for what I see as the more fundamental
waveshaping functions of the CZs, VZ's, Yamaha DX's, TX's, and Synergy
DXII's.
Adding filters would be great fun!
As you said, "probably the best thing is just to wait til it's done..."
I'm waiting, expectantly, and I hope you will.
