Excellent sound but routing software is complicated and not for the faint hearted. Once you understand it, it is ok but still kind of complicated. I would not choose this unit if I did not need all 32 I/O's. But I do, so I am happy. If you will use it with USB (rather than Thunderbolt), do not count on more than 24 I/O to your DAW if your computer is not very new and high specs. You can still use all the 32 physical I/O's though and then control everything in the infamous routing system....... You'll get there in the end.
