@amadeus Thats a huge list of request. I do agree on some fundamental requirement such as easy internal routing and buffer/sample rate bitdepth profile switching. But to extend it enabling a vst/clap plugin on a system-wide level pipewire config is kinda stretch too much (would burden to maintain, if its not compatible with some 3rd party plug in the future). Not to mention that would be prone to feature-creep.

I'd rather choose they or someone would provide a virtual audio device driver at a kernel level like virMIDI does or ARC Engine from Loopback App on Mac to provide the bus grouping and reroute it to them for the possibility of using realtime effects inside the virtual device. Surely this will need another app to manage that virtual audio device capability. As i see hellvum and qpwgraph is quite suffice to provide the patchbay graph for basic need.
