2 APC40's on one computer


I have 2 APC 40 plugged in my MacBook Pro. I want to map specific controls to specific knobs but when I do so, it assigns the control to the knob on both APC at the same time.
Exemple: I assign the volume fader of track 1 in Ableton to the fader 1 on one APC. The fader 1 of the second APC is automatically assigned to the volume fader of track 1 in Ableton.
Want I want to do: Assign vol of track 1 to fader 1 of the first APC and assign vol. of track 9 to fader 1 of the second APC.
Also, is it normal that when I move the APC grid down for on APC, it brings the grid down for both APC's at the same time? The grid can't be separated vertically?
Thanks for your help!!

    Just to make sure; did you assign both apc40 controllers to a different channel in the midi settings?

    Hi Henry!

    We followed your instructions but it didn't work for us. Any ideas why? We're still trying to figure out how to configure ableton so that it doesn't combien our two APCs.

    Thank you!

    Here is how to do it!

    Me and my buddy did this for a performance we did together, follow us here!


    Step 1:
    Open text editor (Mac, for PC's anything that generates a .txt file) and then go to format/ Make Plain Text. This will save the file as a .txt

    Step 2:
    In the text write this exactly: -DontCombineAPCs

    (This is a preprogrammed message that ableton will read upon startup)

    Step 3:

    Safe this file, and place it in this location:


    Step 4:

    Open live and enjoy!
    If It gives you an error, make sure it is not "rich text" in your .txt file, it must be plain text. Cheers!

    Thx the .txt programmed Message ( Don t combine...) bring's the APC 40's Buttons and faders CC's or note messages not on a other or different midi channel !
    Only the session navigation box colored Frame is now separates for both APC 40's .
    I dont know is Your Mac with the intern midi feature your solution ?
    Or use you Bome midi translator to change the message from one APC 40 to a different midi channel...
    I use Win 7.
