Mark V 35 and mini amp gizmo

Hey, proud owner of my first mark V combo amp and first post here. It is a beautiful sounding amp. I couldn't really find any info on this throughout the web. I just got a mini amp gizmo and connected it with the correct cable purchased. It works great standalone as it should. I have a rocktron midi mate which I plugged in and it does work at changing channels but it makes loud pop sounds when changing channels. Any one experience this? I would hate to have to return the mini amp gizmo. When I plugged in my rocktron xpression in the fx loop that came with another set of problems. So anyone ever experience this loud pop sound? :?:

I'm running a similar setup: Mark V:35 Head - tc g-sharp - mini amp gizmo.
I discovered that it only pops when I switch away from a delay setting. So Iguess it is the multi fx that makes the pops.
Try out and please give a feedback!
