Subject: RE: More VCA blabbering

1. Re: ring mod as VCA - you will quite a bit more bleed through from the X
and Y channels than you will on the "real" VCA. The spec says only 40 db
separation, which is clearly audible. I use my RM as a VCA in a pinch, but
the real VCA performance is mucho superior because of the much higher
rejection ratio.

2. To paraphrase some long ago AH sarcasm:
EG linear outputs -> VCA linear inputs makes me SAD (very unnatural sounding
decay on audio signals). EG exp outputs -> VCA linear inputs makes me GLAD
(normal state of affairs for general purpose synthesis). But EG exp
outputs -> VCA exp inputs = WHOMP-ASS punch, for really dynamic short
percussive sounds. So it's good to have exp envelopes (800s are exp, BTW)
plus both exp and linear control voltage inputs on VCAs.
