Two mono pedals in send return

If the loop is after the stack it is mon send stereo return. For your scenario I would try an A/B/Y box on the send to split the signal and feed both pedals simultaneously then send the out of each pedal to one side of the stereo return. I haven’t tried this but logic suggests it would work.

fyi

The PROFILER Stage supports two loops.

yes, but us I'll school Toaster dudes only have one ?
