I tested this just after my last post.
When the MIDI clock isn’t connected I can get it to keep time correctly with a metronome. I set the metronome to 120 bpm and the bpm on the harpeggiator to 120 and it worked as it should. I then connected the H9 to MIDI clock (also on 120bpm) and left all settings in the harpeggiator the same but the rhythms were different.
