My misunderstanding then. I bought the stomp io as I wanted something that let me tweak the sounds at home before going out and playing live (if we ever can again). I didn’t realize that whilst it advertises as coming with AmpliTube delux what I really needed was a more extensive version of the iOS version of amplitube to get benefit of the fuller sounds live, or buy stomp boxes Twice (like acoustic sim) to use with Laptop for recording and live via phone/iPad.
Just feels “wrong” to buy a bit of software from same company twice, given the intention of the stomp io is to integrate studio/live. In future I will make sure any additions I buy are on iOS version, then I know I can use at a gig. Or I’ll just revert to taking the old real Marshall stack (if my back can take it!)
