I've tried to record in Mac book pro i7 with 16 gigas Ram, system Mac Os 10.9.2. I've install Universal control 1.7.2 and studio One

The problem is that the process cut pieces of recording the song; I mean, when you play de recording You notice that the song is not complete; you lost some pieces.

I`ve done a lot ot tests and finally I think the problem is driver Universal Control; it doesn't work well, but I don't know why...
