My Chroma has an EG setup that is simple, but flexible enough to do
what you describe.
Basically, it has no ADSRs, but instead 4 ADRs. The Decay can be set
to infinite to give you an ASR. You apply 2 EGs to the same VCA or
VCF to get complex envelopes. The sustain level (if set to ASR) is
controlled by the CV amount applied to the target. I have some
effective analog piano patches which use 2 EGs with fast attack, one
with fast decay and no release to do the attack transient, the other
with slow decay and short release to do the body envelope. The
attack, decay, and release time are modulation destinations. There is
also a facility for a velocity switch level, which allows EGs to be
set to turn on or off above/below a threshold. Pretty advanced for
its day.
Instead of a big complex module, maybe this would be a more useful
model for a modular - a 1U VC ADR/ASR that you can gang for more
complex stuff.
Hey oldtimers - remember when we hashed out our 1U EG designs a year
or more ago? I still have 2 or 3 panel mockups of the results.
