Hi!
Is there any midi editor available for your controllers (or for one of them)? Many companies give a small utility with which you can change the midi-notes coming out of your controller? If so you could easily change the midi-notes of one device to another channel so there shouldn't be any interference anymore.
However I'm not sure if it's possible with those two controllers as they were made specifically for Ableton in the first place. For example with the Launchcontrol and the Akai MPD32 I was able to do this.
Or you take another software midi translator to change the notes from one device to something else.
Like bomes:

Another easy way would be to upgrade to Resolume 7, here you can choose your midi-devices when mapping:

Hope this helps,
