Reply To: H90 MIDI issues – Not receiving or sending any MIDI messages

[wlcmtthmchn]

Hey!

Thanks so much for this.

I’ve isolated the H90 and the problem is still persisting but with a strange detail.

When connected through MIDI only – no jacks plugged into the IO panel – Clock/CC/PC messages work perfectly.

As soon as a 1/4″ jack is connected to any input or output, it loses the ability to connect. But this only happens when connected to a pedal sending the MIDI signal.

I have tried this through the ES8, Microcosm and EHX 45000 and the problem is consistent with all of them individually (also tried many different cables etc). I’ve also tried separate power supplies and sockets for everything to see if that was an issue but the problem remains the same.

Thanks for your help and hopefully that helps diagnose it a little more.
