Hi

Another suggestion: what about two Envelopes in the Moog-Rogue style
instead of one ADSR. For those who don't know the Rogue envelope:
It has two potentiometers, one for risetime (=Attack), one for falltime
(Decay or Release). You have a switch which selects two envelope modes.

- mode "AD" is like Attack variable, Decay variable, but Sustain at
zero, Release not relevant. The Decay-phase is not stopped by a gate-off.
- mode "AR" is like Attack variable, Decay not relevant, Sustain at 100%
Release variable.

It may depend on the individual style of music, but I use an ADSR
envelope 90% of the time in one of those two settings (percussive or
brass like AD-shape for VCF, percussive AD or organ/string like AR for VCA).
