During my trials I noticed that it’s not really much flexible (Well… maybe the correct description is “not flexing well”)
Even if I disable Bluetooth, I still can hear the steps while I slowly turn my external expression knob. These audible steps are in sync with the changing numbers on the H9 display. Maybe this is not a bug and it’s working how it’s supposed to be. Nevertheless, that make it useless for whammyish smooth pitch bending. Are you people sure that non-bluetooth operation solved that issue for you?
