I have run into a new issue this week. Playback works fine until, after some period of time, playback does not always start at the beginning of a loop. If I repeatedly start and stop, sometimes playback starts on the loop seam and sometimes it doesn’t, causing a delay (playback starts when the loop seam is reached).
Rebooting the looper resolves the issue (playback always starts immediately on the loop seam). I had to do this during a show last night (the boot time takes forever, BTW).
I am using the looper in MIDI receiver mode with external MIDI clock. I suspect that the issue could be caused by the MIDI clock stopping for a period of time, but I am not certain.
