You can set-up the H9 to send out program changes whenever its preset changes by enabling the PGM.XMT setting in the H9's system settings. This option doesn't come up a lot, and I just noticed that the configuration setting you need to enable isn't in H9 Control. You'll want to press the HotKnob switch and the right footswitch simultaneously to get into system mode, scroll with the wheel to MIDI, press the HotKnob switch to go into the MIDI settings, scroll with the wheel to PGM.XMT, press the HotKnob to go into the PGM.XMT (Program Transmit) setting, scroll with the wheel to turn it ON, and then exit system mode again by pressing the HotKnob and right footswitch.
