[sdiy] Poly 800 (was DSP MIDI Synth (was Re: 566 Functional Replacement))

[rsdio at audiobanshee.com]

When the Poly 800 was brand new, I was torn by the paraphonic aspect. I ended up passing on the product. It was one of the few keyboards I might have afforded in college, but I decided it was better to save up for a “real” poly.

However, I thought that only the VCF was monophonic. I got the impression that the digital envelopes were polyphonic. Weren’t there 8 of each of the 3 types of envelopes? I’d have to play one again to hear the answer.
