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.

Like said before, I’ve noticed 3 different notes-overviews so far. Please let me know if you have another one than these 3 below? Feel free to share that image in the comments, I will add it to this list and give you a big ‘hooray!’ :)

This is the notes-overview that matches my APC40, bought in The Netherlands:

Another mapping that pops up quite often, is this one which seems to come from the USA, but I’m not 100% sure of that:

The last one that I’ve noticed in a post on DJTT by just one guy is this one, from which I’ve also no clue where the original APC40 is coming from (UK?)


So already 3 versions which of course make it impossible to create a worldwide TSI. But of course what I can do is share my TSI’s including a screenshot of the APC with all functions on it, to help you a bit with how to program the TSI, how to use the modifiers, what kind of functions, fx and faders to use, etc. So regularly check out the controller mappings section for some new stuff in there!

Let me know your thoughts on this and if possible share some image/pdf on how your controllers’ notes are setup, maybe there are even more versions. Hopefully suddenly AKAI pop’s up with some intel on this, for now we are just one in music, not in sharing TSI’s…
