Yes. If you put the H90 in duel mode you essentially have two EXs channel. The H90 has two sets of performances one set for single mode and the other for duel mode. The stage EXs inserts are mono in stereo out… the H90 can be run stereo in/out… but the stage only has mono in/stereo out for it's EXs loop inserts
I also set my H90 to run in line mode, not instrument.
Thanks for all the info GL! What's the benefit of running in line mode rather than instrument?
