@unfa Carla can run on HaikuOS! No MIDI, but audio works via SDL engine.
LMMS is there too by the way.

I try it from time to time, big fan <3
The stuff I need the most all works there, with the exception of docker (though that is kinda expected)

Once they have good USB streaming support (so sound cards work) I am considering changing, or at least trying it more seriously
