Thanks so much for the tips @NothanUmber. I tried the MPE vs MPE+, that didn’t fix it. I ordered the dongles I need to try the computer solution. Maybe it will turn out to be the MIDI Host? .
I don’t think I have the channels wrong. When I first connected this setup I had the channels wrong but that created a pattern where some notes would sound and some notes would not sound, but in a regular pattern.
