ENV with exponential curve shapes


I wonder if/how it could be realized to get an exponential curve shape for example on the release stage via the Modifier section?

Many thanks in advance

Perhaps it’s sufficient to multiply the env signal with itself via a modifier?

That´s the first thing I tried but not working.
Anyway thanks

This does work, I use it a lot for drum sounds. e.g

Modul.  1|srce mod1|dest osc1|amnt   32
Modif.  1|in1  env1|in2  env1|oper prod  (squaring the Env1 envelope)

Indeed exponential behavior works.
Me culpa, I was looking for a logarithmic curve to get an smooth release phase for envelopes.
