So far, so good on my 3rd try to get 3.6 to not be buggy. This time completely uninstalled and cleaned out via Revo all HX software and re-installed latest. Then ran the update from HX Edit. Typically I was using Line 6 Updater for all FW updates. I did have one weird thing happen a few minutes ago where the wah in my chain turned itself on when I switched back to the patch but saved it again in the off state so we shall see.
Havent really tried any of the new stuff other the first day I tried the 3.6 update I messed around with the Grammatico and the Elmsley a little but they aren't my cup of tea really. Not the kind of circuit I'd dig IRL either.
