Here’s the setup I’d suggest for getting MIDI to work nicely:
- update to 2021-10-09 Update (or later) - there’s a couple of MIDI fixes here that might help
- With your Prophet X as controller, go to Sync / Control Settings and setup the port (USB H) and channel. Echo is fine ON.
- With this setup, you DON’T need to enable Notes, Velocity or CC In under the Sync / USB Host Jack menu unless you want to control Audio Tracks with the Prophet.
- On your MIDI Track, you also DON’T need to enable In From USB Host in the Track Settings / MIDI Ports menu.
- You DO need to set the output Port and Channel to match your ESQ-1.
- Now, when you’re ready to play/record, press the A button on your MIDI Track. This will enable ‘MIDI Focus’ and allow you to play and record to that Track for as long as the A button is lit. This will work for any MIDI Track(s).
tl:dr - the Control Settings menu in Sync allows you to set up your master controller keyboard which can be used with any MIDI track with ‘MIDI focus’.
