Bitwig knocked it out of the park coming out the gate with Linux support. Can't say I'm surprised though, it's made by the original team that made Ableton Live.
But they were not the original team that made Live, that is a bit misleading.
I was just thinking if there is a way to ask for features.. and there is! https://bitwish.top/c/features/5
I will add the request for ALSA sequencer devices, which I think should include Jack ones.. but I will investigate this further, as maybe I'm wrong. There is a bridge for sure.
Anyway just don't hijack the MIDI device and be nicer with the linux MIDI ecosystem is a must.
