Title: envelope segments
Post by: matrix12x on April 26, 2021, 02:15:49 AM

Is there a way to make the segments of the envelopes logarithmic (maybe using the mod matrix)? Specifically the decay segment.

 I don't know exactly what you call "logarithmic". Any picture ?
The different segment are defined here in the code :

Oh, the Decay segment is exponential. I didn't realize that. I wrongly assumed it was linear based on the linear representation in the editor. I should have looked in the code.

A logarithmic function is the inverse of the exponential function. However, I think I actually meant exponential.

Thanks. :-)
