Yes, I've often heard that from Matrix 12 owners, but I don't think I have
a keyboard that sends release velocity, or that I could play
well-enough to take advantage of it if it did.

Would you care too elaborate on that?? Do you find that
effect useful even when you can vary the gate time??
Anyway, I never heard of a MOTM-880, have no idea what kind of EG a
CS-80 has, or what Scott is doing. Has he posted anything about it??
Basically, what I was doing was trying to cook up a "performance
envelope", an expressive EG for playing leads from a MIDI keyboard
using velocity, entirely for my own purposes.

In trying to get "realistic" percussive sounds, I found that attack
level was as important, or even more important, than attack rate.
With a higher attack level, you get a naturally longer decay even if
the decay rate is fixed, as well as an overall increase in loudness when
used with a VCA.
Of course being able to control attack rate with velocity is very
important for playing pads and strings, and useful for percussion as
well.

I'm sure :)

That's more like the Encore UEG, which is an excellent module. Now
if you took that, and added CV for everything and standard MOTM-sized
knobs, even after shaving it down to only four stages (ADSR) it would
still be 4U!!
The Serge TSG/DSG modules are excellent designs as well, yet their VC
ADSR is a separate module. I'm all for multi-purpose modules, but I
think it might more efficient to have two or more different EG
modules that take up 1U or 2U than one enormous module that tries to
do everything.

I agree. It's better to have a swiss army knife _and_ a leatherman tool :)

That is a very good point. If someone were concerned with that, they
could use the note CV to modulate decay.

Although I've found that random doesn't sound human, I see your
point. VC delay could be modulated to change the feel of a sequence.

In addition to all those good ideas, there is attack level, hold,
voltage scaling, lin/exp, gate/trigger modes, etc. Which would make
it a 5U module!!
As much as I appreciate all of the ideas expressed in this thread, it
supports a massive amount of features. Imho, too many to fit into
one module. So I suggest the best approach would be a division of
labor over several different modules.
