Took the HX (which I haven't been using much) to a friends house tonight to see what we can do with some kind of weird busking ambient / prog thing. I hadn't used the looper on this before, and I am not good with loopers, but how good is the looper on it? Answer, very good. I guess I couldn't use one before because they are all hard to use, one button doing multiple things make them useless to me. But you can start looping, go back to the patch and apply effects, and loop with effects etc.
