(resolved) overbridge glitch unable to use for recording

Finally I’ve had the time to test out overbridge and although not perfect its pretty wicked BUT im getting a huge digital glitch which seems quite random and definitely makes it non recordable atm. Anyone else experienced this and has a work around? Im running osx lion, ableton 9, latest OB beta, and a ua101 audio interface to record synths. Also why do I have to drop my buffer size and what does this do for my audio quality?

Turns out it was my audio interface causing the glitch. Dropping the sample rate to 44.1 has made it all usable. Overbridge is good and fairly solid on my old system.
