FLstudio on macOS X and this functionality seems does not works here. It only works for native FLstudio plugins like 3x Osc, EQ etc. Do you have an idea how to set this things to work on the system ...
back in I can't control the volume knobs when it reappears I try uninstalling FLStudio and reinstalling it but it keeps doing the same thing I don't see any errors although it did do it when I was in version 12.4 ...
