So I did find a workaround for this tonight. I’ve got a loop selector switch. Basically an in and an out with two mono effects loop. The foot switch just switches between loop A and loop B.

So I routed fx loop L from the HX Stomp to input and output 1 on the H90. Then I took fx loop R and sent it into the loop selector pedal. Loop A goes to in and out 2 on the H90 and loop B goes to input and output 3. So now I can do both dual and insert routing with rewiring everything just one footswitch click on the loop selector.

Ideally I’d love to lose this pedal and just have this functionality built in to the H90 but it will work for now.
