Did you even actually have MIDI dropout due to 1/4″ connections? That turned out not to be real, right? Just you being confused?
The USB vs 5-pin thing is not a malfunction. It is normal operation. It is in the manual.
Oh it’s very real, I assure you. At least with the H9 Max. Go ahead try it. Put you H9 max 3rd down from a daisy chain of MIDI devices ( no USB or editors). I bet it won’t respond to MIDI…Pull out the 1/4″ inch cables and the MIDI data will flow.
Confused?… You’re damn right I’m confused. That an modern, 700$ pedal can’t do something my 80’s, 30$ Quadraverb can.
