That Chroma setup does sound pretty cool.

Maybe a VC AR in combination with the satnddard ADSR we have would do the
job, be a bit cheaper, and fit on a 1u panel.

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.
