have to say i prefer analog envelopes, for various reasons.

to start off,

for acoustic, snappy, from sound of hitting wood, to plinking on a porcelan vase, to a small
drum skin percussion, i love Maths. its slopes and the log/lin/exp control are just perfect.
i keep a narrow vca nearby if i want to automate slope change, by self patching (env out into
vca into maths cv ctrl inputs - rise,fall or both)

for classic Rolandish snap/twang in ADSR form, the FC has done well with his X-Envelope.
reportedly designed after the transistor env in SH101. i have a pair and its great they take
little space. however, if you need CV control, then you might look at Befaco or Instruo.
havent tried em tho.

also, in the AD/AR domain, i do like what i am hearing from Delta-V. very punchy. it has
that micro short hold phase, just like minimoog envs. i was looking into getting another
Maths for a while, but now im debating should i add this instead, for little variety sake.
