No, I'm not fucking kidding.
I still have a couple of things to try, but I CANNOT get the new Axe-Fx firmware to take using Soop's Firestudio. From people with an Axe-Fx... I'd really like to basically borrow a MidiSport 2x2 or something similar that works for you.
Obviously I'd pay shipping both ways and theoretically would just need it for a night or two.
I could help you out there dude. My midisport 2X2 worked very easily.
