I'm having an issue with the MIDI clock on the H9. Every time I load a new preset via MIDI PC or Left Footswitch, the MIDI clock doesn't seem to work. It start the synchronization only when I tap a tempo.
I just tried this out with the latest H9 firmware, and it worked fine when changing the MIDI clock tempo being output when a preset was loaded either via MIDI PC or the left footswitch. I can upload a video showing this if you'd like. What makes you think this isn't working? What do you have connected together?
You'll want to check and make sure that your H9 is configured to output MIDI Clock, and you can't have a USB cable and a MIDI cable connected to it simultaneously.
