I have that identical rig. Here is my configuration: (Assuming mono operation) Triaxis out to 2:90 in, put the Replifex in the Triaxis loop, attach the phantom powered midi pedal (7 pin) out of the Triaxis. Every time you switch or bank up and down on the floor pedal, a signal is sent to the Triaxis to change patches. Since the Replifex is in the loop, it will switch simultaneously. Note: you MUST turn the FX loop on the triaxis and save it for it to switch the processor patch on every processor patch used, if not, you will get the Triaxis only! Once you've settled on a sound out of the Triaxis, simply write the processor patch and hit save. I know there are several different ways to configure (triaxis to Replifex to 2:90, etc.) but this seemed the most no-nonsense set up for me. I encourage you to experiment!
