Right, I'm trialling Ableton. I was using 8.0.2 now I'm using 8.2.2.

I got the same issue in each version.

I get the same issue regardless of wether I route audio through my on board sound card or my USB NI Audio 2 sound card.

What happens is that when I preview a track it plays fine, the minute I put it in one of my audio channels and play it it seems to stutter very slightly almost like it misses part of the beat. I liken it most to that slightly irregular sound you get when doing a key correction with some CDJ1000s. Totally unacceptable, and its definitely an issue, theres no way that anyone wouldn't notice this. The flow of the track just feels wrong, and I have them playing at their 'native' BPM.

I don't know where to start, but if anyone can help, or point me towards a better place to look then I'd be very grateful. Pretty sure it has something to do with sample rate, but why, and where do. I go with it?

Cheers all.

PS I'm using an Alienware M15x with a 920xm CPU running all 4 cores @ 3.2ghz and 8gb RAM with an Intel SSD. This machine will eat most others for breakfast, basically all I'm saying is that it's up to the job of running Ableton.
