Hi,

Is it possible to use low-level reverb zones with high-level volume control like VCAs and busses?

It seems setting up the volume by using VCAs or busses does not affect the wet signal from core reverb zones. Or maybe there is another way to control reverb zones volume by high-level API?

Thanks!

Currently it is not possible to use low-level Reverb3D with any of the FMOD Studio bus or VCA features. It would be better to look into using reverb effects on return buses and controlling them using snapshots.
