Nope: it’s still exactly the same as Push 1 - a rich controller for a piece of desktop software, and the desktop software is powering the UI on Push. There’s no audio whatsoever inside it, and you can’t do anything with it without a computer. (It can still, I believe, act as a plain old USB MIDI controller, sans Live, if you’d like).
Most of the new features also work on Push 1 (as I confirmed this morning), with very few exceptions, and Ableton seem keen to continue developing for Push 1 where possible. Essentially, it’s a sensibly rejigged layout of the P1, with That Screen.
Although: P2 is made by Ableton themselves - compared to P1, which was a collaboration with Akai. For me, that’s the most interesting thing - a software company really doubling down on becoming a hardware company too.
