audio glitches...

Gents, im having some problems with recording/monitoring of audio... im getting weird glitching that sounds like buffer over loads on a daw... It happens when im monitoring and then and then at playback but then after a while it disappears?!?!?

i do like the box and especially the mpc style of sequencing (which im new too) but its pretty buggy in places, right? i might take it back and get a 1000, i fancied having more outs almost straight away any way.. any opinions?

I had some audio dropouts recently but I'm pretty sure it was because I was running out of memory. Other than that, I've not found it to be very buggy or unstable.
