Specific question for those with the new GTs and a foot switch. I thought I saw this on a demo video in passing, but can't seem to find it again. Does the looper allow you change patches after recording a loop? Meaning, lay a couple chords down with patch 1 and then switch to patch 2 for a lead tone while leaving the chords running in patch 1? This seems like a really useful feature, if it works that way. Thanks for the info!
