I was getting this as well. It seemed to me like it was usually a sound from one of the bounds of the loop that didnāt appear to get overwritten when record got turned on. So w/ a negative voltage plugged into THAT the rest of the sound was decaying in the loop but the blip on the edge would linger, and sometimes prove hard to remove even if I removed the loop. But like others have reported, i feel like these things would start to happen as other issues cropped up. Or could be a mixture of naĆÆvetĆ© and smaller bugs. So iām at a loss to really isolate what itās going on.
An issue which seemed related in my head was that Iād often get a little pop at the loop bounds when the loop went across the edge. This reminded me a lot of the op-1 tape which had this same issue for a while (i think largely fixed in the newest os) and recording on a looping tape track could accumulate pops at the loop points. Iām assuming the little pop is a discontinuity in the wave(?) as it could be tamed w/ certain sounds, but it made setting a short loop and using the device as a delay tricky as Iād often end up w/ a frequently recurring pop in the delay line. As both these issues seemed to be happening at the bounds of the loop it struck me they might be related.
Anyway, while my 4-5 hours messing around w/ this thing yesterday had some irksome moments which Iād round towards learning curve / bugs, I was on the whole utterly blown away by how cool this module is and how much potential it had.
