How are you connecting to the H9? Over MIDI or Bluetooth? And from what kind of device are you connecting to the H9? iOS, Mac OS X or Windows?
Is this a new H9? Had it been working properly previously? If so, have you changed anything recently? For example have you updated the H9 software?
I’m using my iPhone to connect to it. I ran a couple of the updates last night after messing with the presets already on it. I bought it used and it was working fine until I updated it.
