I'm using windows 7, Intel core i5 processor with 4GB ram. I have 3 500 GB hard drives, the one with biab on has 200GB free.

Everything else sounds fine and i wasn't even stretching the tempo of the track, it was at 140 bpm.

I've tried testing with and without +/- files and disabled fast generation.

I think my system is up to the job and its only with the few real track soloists i mentioned, all the others sound fine.
