ML5 in HX Stomp loop

So i’m a pretty greedy nerd and want all of the options. I thought putting the ML5 in the Loop of my HX Stomp would solve a lot of problems as I’d be able to “move” the pedals in the ML5 anywhere I wanted in the Stomp’s signal chain. This is completely doable however…

There is an INSANE amount of cross talk digital noise when some digital pedals are in the loops of the ML5. The noise is even worse when midi is plugged in. This happens even when the external loop block is disabled, so it’s not signal noise.

Signal path:

  • Tuner
  • Stomp
  • ML5 in Stomp Loop
  • amp

NB: it doesn’t happen when I use analogue / drive pedals

I have no clue why this is happening. Any ideas?
