I have some SFZ patches that do exactly what OP was asking. But when importing these SFZ files into Redux that have different envelopes per group like this:
… Redux will create a single modulation set without ANY of the defined operators like envelopes, eqs etc. for all the samples.
Why is Redux not creating a modulation set per group with the corresponding envelope settings and fx chains? It seems to be supported when doing it manually, so the feature itself seems to be avilable.
I see. What about expanding SFZ import/export to the modulation set and fx chain presets? There are a lot of great Kontakt patches out there that are simple enough to be converted to Redux using SFZ.
