Some of you already noticed that the APC controller mappings I’ve provided somehow don’t 100% correctly work on your APC40 with Traktor Pro. Most errors appear on the red/blue/green button sections, but also some people seem to have strange behaviour on the track selection buttons.

While I was checking out what could be the reason, I found a possible reason for all these strange behaviours; the APC40 notes-overviews are different per country and/or production batch and/or ?. Until now I’ve seen various notes-overviews, in total I’ve already noticed 3 different ones so far. I’ve no idea whether this can be set manually but nobody on any forum, nor on the Ableton or AKAI website, has any information about this. Some of you might not even care :) , but this makes sharing TSI and controller mappings for i.e. Ableton quite hard.
