I had an issue last night with Abelton/ Jitter. I was generating visuals with jitter (made into a max4l patch) using audio from Abelton and sending the data via send and receive objects within Abelton. I had rehearsed the previous few days and not had any issues with digital clicks, but when I began implementing a homemade OSC controller (run through an external max patch) I began having terrible digital clips. The Abelton set was very light, only a small compressor and EQ to process the vocals and the CPU usage was topping out at 14%. I adjusted the buffer size to 1024 and still had the same problem. I removed the the OSC controller rebooted and ran the piece, and then everything was fine! This is where it gets weird. This clean run was 1.5 hours before the performance. 5 minutes before the performance I rebooted the computer, opened the patch, and then in the performance the digital clicks were so much worse than before!

Does anyone have any idea what this could come from? I am running Abelton 9 on a mac pro 10.10.5 Yosemite using a Motu ultralitemk3. Could it have something to do with the Motu drivers? I am 99.9% sure it is not in the Max patch... Could it be from the Motu being left on for a long time? (10 hours or so... build up was at 11 in the morning.. show at 21:00)

Any advice would be greatly appreciated!
