This has been happening for the past month—
Every time i use the Stage, after some brief period of time (5-10 minutes?) it crashes. Sound stops, and at first the screen is normal, but then the screen goes to the KEMPER PROFILER readout, but then it hangs and doesn't reboot itself. I have to unplug, replug and that corrects the problem, until the next time. Today, it happened after just two minutes.
I didn't do anything. I was just playing a simple profile, not tweaking, not footswitching, nothing. Just playing. That's the same experience each time it crashes—not due to my interacting with the Stage or the editor.
I'm running RM 3.4.57 and firmware is current, 220.127.116.11833
