Midi Loop Switch recommendations

Does anyone use a midi loop switch to incorporate analog fx pedals into their midi chain of MIDI Maestro-Beat Buddy? Right now I have MM–>BB–>Boss VE500 all working well together to link my setlist. Now I hope to incorporate my guitar pedals into the mix. I’ve had no luck with retail shops near or far. I cannot imagine this is unrealistic. Any recommendations would be much appreciated.
