I am trying to sync my P12 with Ableton's clock but the BPM always fluctuates when I start the clock in Ableton, making it very difficult to get a good sounding recording. I've searched the forums a lot and have seen a lot of similar behavior with the REV models and different DAWs (especially Logic). I'm wondering if anyone has experienced similar behavior or has found a solution. I tried switching from a USB connection to a MIDI cable and still get the same behavior. Thank you for your help!
