Ok seems i got it working a bit without crashing by changing the buffer size.
I have sound coming OUT of Reason and OUT of the computer trough the Scarlett 2i2, but recording sound seems a different story and that is exactly the reason why i purchased this audio interface.
I can't get this to work, as there is no audio signal incoming http://www.youtube.com/watch?v=7Vfu4n4KcAI
-. I can only select 44100, not 48000 or 96000
Result in no sound at all.
-. It only shows 16-bit while this is a 24-bit audio interface
