I had the aux in set to inst not line so that could be the problem. Ive promised my wife attention tonight so I won't be able to test until tomorrow.
Have you tried plugging the guitar directly into the aeros input (eliminating the stomp send)?
This works fine, I just really want the loops to have a delay/reverb tail at times when I stop or delete tracks ( great for ambient looping)
Ive had it for about a week now so haven't had too much time with it, ive had many loopers including software so im pretty savvy to the loop world. I find the midi maestro is kind of compulsory. So far I love it, its not perfect which I can explain more tomorrow but the developers are working on a new firmware to be out hopefully soon which will make to a better workflow, I do appreciate how they listen to the things I have suggested in regards to track locking and a few other things (loop decay and fades) etc...ask any questions you like and I will answer tomorrow ...
