I started using it under Windows with REAPER. Probably the best driver for this combination, but it caused me quite a few annoying moments right at the beginning. The Mackie Control Universal goes solidly with it, but serves too little functionality. It took me all afternoon to find the Klinke add-on (here: https://bitbucket.org/Klinkenstecker/csurf_klinke_mcu/downloads), and with this one it's already usable... but I have no idea yet, either. It's no longer in active development. I thought about sending it back, but right now it's working pretty much as it should, so I don't know.
