Hi,
I am having the same problem in both sculpto and spectro. I can edit envelopes fine, but for the life of me I cannot figure out how to play what I’ve edited. I am sure the solution is obvious, but I am not getting it…
using plogue bidule if that makes a difference.
Thnx,
Rich

In both cases, these are plugins that rely on a DAW having a timeline…that provides time/position information to the plugin. Some editors or hosts do not do that; for example, SoundForge won’t correctly handle Spectro or Sculpto because they don’t provide position information to the plugin.
I don’t use Bidule, so I can’t tell you for certain, but I suspect that is the problem. Schwa may have a more definitive answer.

THanks…I am sure that’s it…I’ll try hooking a sequencer up in bidule…I was giving it timing info from a metronome but no timeline.
