Triaxis switch and preamp/distortion pedal.

[nexus]

Is there anyway to use that triaxis switching for footpedal??

I use 2 for 2:90 modes, and there is two more.
I liked to have bb preamp or something like that (not decided yet)for some sounds, but i don´t want it to my pedalboard. Just inside rack.

anyway to do this without something switching rackunit??

I use Rocktron All Access midi controller.

Thanks
