Hello sharshbarger,
This may be a case of an incompatible MIDI cable. Are you using the Strymon MIDI EXP cable by chance? In my setup at home, I confirmed there aren’t any issues sending MIDI out of the H90 5-pin DIN to another regular pedal, and then I tried going from H90 5-pin to TRS to an Eventide UltraTap without any issues. Of course, the UltraTap had to be set to receive on the MIDI TRS on the EXP input. The cable I use for my builds is this one from Disaster Area: https://www.disasterareadesigns.com/shop/p/5p-trs-pro-midi-cableThese have Pins 2, 4, 5 wired through and are compatible with MIDI.org TRS type-A.
Some time ago I researched this and came upon a thread in a gear forum that said:
“I emailed Strymon support about the Strymon MIDI Cable and asked them about the cable trying to find out if they adopted the MIDI DIN5 to TRS A OR B standard which basically flips the pins 2&3’s polarity on the TRS Tip and Sleeve respectively. What I got back was neither! Strymon uses a proprietary cable.”
