Hi
This has stated recently. I start a new project and record the first loop, when I stop record and the loop starts to play back there is loud click at the start of the first iteration of the loop. When I say loud click it is the sound you get when you switch the Aeros on or of when plugged in to speakers.
Only had it happen on the first loop of a new project and not every time.
Edit: Just happened again but this time on the second loop
