I used a Delta 1010lt
8 outs and ins was fine. 10 ins recorded fine. As soon as I enable the 10th out and hit play I get access violations.. as mentioned previously I didn't listen to the recorded tracks play back, but they 'appeared' fine. Each wrote on its own designated track, none looked skewed in the waveforms..

I do not work here, but the benefits are still awesome
