My Zoia and the two Chase Bliss pedals I own have TRS MIDI but i’ve only used the Zoia MIDI functions - just connecting a keyboard to play synth patches.
Sounds like factory just got Trash80/DirtyWave’s order/specs wrong on the TRS part, unless I misread something. I’m personally fine with Trash80’s call to go ahead with dropping the Type B jack to avoid holding up production, although I respect the right of other customers to feel differently.
