Any software that accepts MIDI as input will work with physical devices that output MIDI. That's the whole thing there.
I think what you're asking about is an input device that can map to whatever software you want to run, and this should be ALMOST and USB device that has uses a generic HID interface.
If you're talking specifically about a mixer built for purpose, that doesn't fall into either of the above categories if you want the sound processing to happen in software. You probably want something that does the DAC and then inputs to your machine maybe?
If not, check this out, then go looking for any device that will emit HID events as output, and you can turn anything into what you want. Numpads, extra mouse, touchpads, maybe a Korg device (well known to work under Linux).
an input device that can map to whatever software you want to run
Yes, this actually. What I should've asked then is about what software can adjust sound filters per program running on my pc. Like, if I want to compress someone's audio coming from discord while increasing the lows of the audio coming from vlc. The software would do that. It'd just be up to the its features available whether it'll take my HID's (human interface device) events. Ty
The very basic version only allowing for one filter would be EasyEffects. If you want to use different filters for different programs you can install some LV2-plugins or bundles and then configure LV2-Plugins directly in pipewire (which is a bit of a pain) or use a GUI plugin-host like Calf and probably some patchbay (qpwgraph, patchmatrix, ...)
Or even better: try Carla, it may be a exactly what you want and can be remote controlled via MIDI or OSC
Carla looks amazing, thanks for sharing.
