If your MIDI controller does not provide a native Control Surface Script (e.g. Korg nanoKONTROL2), you can create an own script to control at least the eight dials of the custom bank. It might sound a bit like a nerdy task for a programmer or computer specialist, but actually it is very simple and you can even connect the pitch bend or modulation wheel of your keyboard in that way.
Open the path of Ableton’s preferences in the File Explorer or Finder (1) . You have to activate hidden items to see the folder “AppData”. Create a new folder (2) and give it for example the name myScript (3). Finally, copy the file UserConfiguration.txt in your new created folder (4). The name of the file needs to remain unchanged!!!
Mac: HD:/Users/[Username]/Library/Preferences/Ableton/Live x.x.x/User Remote Scripts
Open the script with an editor. On windows for example Notepad or Textedit on a Mac. Alternatively, you can also install the open source software Notepad++.
Let’s have a look to the script and edit three parts of it:
The quickest way to find out these information is probably to switch on the MIDI assignment in Ableton and to map by way of trial the dials which you want to use to a parameter in Ableton. Do not forget to delete your mappings afterwards!!!
Copy the values to the script. Attention, there is one little trap you can run into: The script counts the MIDI channels from 0-15, but the interface of Ableton displays them from 1-16. Therefore, you have to reduce the number by minus 1.
Save the script and reopen Ableton and choose in the settings your script as Control Surface and your MIDI controller as input and output. Do not forget to activate the MIDI port for Track and Remote.
