Although not supported , anybody tried this yet. I run 8.5 ( not supported either ) and it runs flawlessly.
Yes, seem to work. But I got a quite significant performance drop regarding audio asio performance meter. Got much glitches/dropouts on projects that did not have problem in 8.5.20. Typically high load with playing the midikeyboard. This might be a 10.9.5 issue or a c9 issue (9.0.1).
