It's honestly a really well designed project. The engine and gui can run independently of each other so you can run the engine headless and interface with it via osc. This is what I do and works very well. The midi sync is very good and remains sync for days on end if your jack is stable. I make music with a friend who runs ableton and we both do live looping with a shared clock and never run into problems. Anyway, give it a spin!
