I do not know if this is still an issue in newer versions, so maybe this is already fixed or updated. If so, consider this to be outdated please I am using Fmod 2.00.07.
When using a sidechain on a Bus I can either route that into a Compressor or into the Volume Knob Modulation.
For Compressor i can deselect “Link” to unlink all affected channels and only duck the channels on which audio is played. With this I can avoid e.g. ducking the rear speakers even so i only play voice on the center speaker.
I can not unlink the channels for the Volume Knob Modulation! Actually I would expect this to be the default behaviour…
Thanks so much
