MX-1 and Ableton Glitch

[enotide]

I have a Kick Drum loop playing back in Live, and the MX is in EXT mode.
Every so often the First kick drum (on the one) will glitch a little bit, not all the time though.
Don't know if i'm over looking a setting or what, any ideas?

Thanks in advance.

Figured it out, It was the Buffer size. On my computer it glitches every once in a while at 512, but smooth at 1024.

Dropping the sample rate to 44.1 helps as well. The default 96 is a drain on the processor.
