Hi Richard!
I'm starting to work on a library for Dune and have stumbled upon this limitation when working on cinematic layered sounds.
For example, say I have a Braaam on FX1 layered on top of a kick that goes into FX2. Now I'd like to apply a compressor to everything... which AFAIK is not possible.
One quick solution could be adding a slot for a single effect in the master output like a compressor or limiter.
Ideally I'd love to have an FX3 global effects bus so that there could be multiple routing options similar to the routing options in the filters. Eg: FX1 > FX2 > FX3, or FX1 + FX2 in parallel into FX3, etc. Alas I imagine this would be pretty complex to implement.
