Please excuse my lapse in terms as I confused Presets with Programs; my fault. You are correct, there is no way to switch PRESETS via MIDI. It is best practice to create Programs with different presets as these will change seamlessly with spillover. But the work has to be done in advance of using MIDI.
On the other hand, it is possible to changes presets using the front panel controls in real time or with H90 Control on iPad or your computer.
