Reply to Combining midi maps?

Hello, just got my midi fighter pro super knob and i love it only problem is when I enable the midi map for the midi fighter my denon dns-3700 no longer are functional, and vice versa. So my question is how can I get the midi mapping to work on my denons and midi fighter? Im using SSL with a SL3, the Denon Dn-s3700s and the midi fighter of course. Thanks for any help!
