Is there a way to have VST notes play backwards? without converting them to samples…
Reverse ADSR curves?
No there isn’t. (And it’s not a logically possible feature unless you make an arbritrary decision on the duration of the sound in normal mode).
If your VSTi is a sampler then it might have a reverse play option onboard.
Converting to samples, or simply sampling on the fly?
“Backman” is a fun one-trick pony (win only)
