Re: A-141-2 envelope type
2015-01-30 by steve mantz
Most analogue envelopes are expo/log as they follow the standard RC charge/discharge curve. You may well be able to change the curve shapes by feeding back the envelope into the CV ins. It'll be less intuitive as the default is log/expo, won't be possible to change from convex to concave either.
The only CV'able full ADSR envelopes I know of are the Tiptop Z4000, the Circuit Abbey ADSR Jnr (needs the expander) and the Frequency Central Loopy ADSR. The latter has a log/lin slope switch. Basic version only has CV over total time. The RS-60 has control over decay. Of course if you're happy to work with 2 stage AD/AR envelopes there are plenty of Serge / Buchla type modules including the A171-2 VCS Serge copy.
