I had issues mating my Studio Max with my Icon Qcon control surfaces, which worked absolutely fine with my previous Intel Mac but were a nightmare with my Studio Max. However I wouldn't take my example as being representative across the board, because the issues I experienced were because Icon have their head in the sand about the very well publicised incompatibility problems between their devices' firmware and Pro/Max/Ultra chips. Unless you have the same control surfaces as me, it seems unlikely you will run into the same issues.Wow, no, hadn’t heard about it. Is there a thread/official info?
