At this moment in time I'll skip the rest of your msg since I don't know all that much about midi nor about switching back and forth between nouveau and nvidia. As the maintainer and author of the current linux-rt package both on aur and in the archaudio-production repo, I'd be interested in getting the midi performance tested and approved though One thing did catch my attention though. you have your rme audio card in a slot that shares irq with the nvidia and with several usb devices. Imo that is really asking for trouble and you need to at the very least get your soundcard to use another interrupt than the nvidia card... -- Joakim
