instead of choosing the old Apc40 - i've decided to try this new mk2 (a complete remake version)
first impression:
*robust construction, steady knobs and faders.
*slim size (nicer format)
*bigger buttons in the launchgrid.
*led in buttons give a better visual feedback of clips and where selection in the clip-launcher is located
*knobs feels steady and more robust.
*faders feels improved, movement and durability
*layout and other buttons feels better places and more for "live" use (subjective of course)
over all feeling:
i've only used it for a week, but the feeling is that it suits me better in how i wanna use it. and how to select and control ableton in a live-situation, without having the need to look at the screen and/or use mouse to select and navigate.
positive
+ rigid construction
+ knobs and faders feels more robust
+ multicolored LED-feedback in launchgrid
negative
- missing a 4 by 2 knobs layout for assignable knobs (my subjective opinion)
-crossfader / A-B fader is no longer easy to switch when worn out (old apc had an easy mount from backside of the controller)
-kind of expensive in my opinion
*this is first impression - still working with it, and still find new stuff i like with it
overall - a really nice controller for Ableton Live (best so far)
