How to use several USB instruments without going insane?
Hi! Pipewire's features seem incredible but I have not been able to make it work for my setup so far.
I use an Arch-based distro, an ancient but rock-solid Edirol UA-25EX soundcard and Reaper as my DAW. Due to a poorly suppressed gear acquisition syndrome, I also have a SP-404 MKII and a CK-61 keyboard that I wish to use mostly via USB since it's more convenient than audio cables.
Normal use works without issue: Firefox, Spotify, etc. is played perfectly through my soundcard. I can see changes I make in pipewire.conf on my soundcard in pw-top and coppwr. However, my sampler and keyboard sound like a circuit-bent Atari 2600 whenever I play in my DAW.
When Reaper is open, pw-top shows that both instruments have a QUANT of zero and my guess is that it's the most likely cause of my problems. No matter what I try to modify, QUANT stays at zero for these devices.
Each device also have a different bitrate and samplerate combination, another possible problem (UA-25EX: 24bit/48000, SP: 16bit:48000, CK-61: 16bit/41000).
So...I'm not sure what to do next. Is there a way to make these three USB connexions work together with Pipewire? I'd be happy to sacrifice some audio quality for complete compatibility, like setting everything to 16bit 41000.
Thank you all for your help!
