Click sounds from 5v sync? So I was jamming with a Monologue and a PO 12 and there was this click sound for each beat (both ways, meaning when either one of them was the slave), although only audible when the volume was down all the way. Could it be because I'm using a suposedly stereo cable as a patch that doesn't work properly so it's a mono now? (Sorry for my complete lack of knowledge, just starting now with all this, don't know shit. Also not English native).
