From the H9 Owner's Manual:
[XMT.MAP] – Create a MIDI Program Change Transmit Map
When the Left Footswitch loads a Preset, a MIDI Program Change message can be
transmitted from the MIDI Out jack or USB to control an external device – e.g.,
another Eventide Stompbox, an Eventide Eclipse, an Eventide H8000FW, etc.
[PGM.XMT] – MIDI Program Change Transmit Enable (ON, OFF)
Press the HOTKNOB button to select. Turn the Knob to set MIDI Program Change
transmit ON or OFF. If ON, a MIDI Program change message is transmitted
whenever a Footswitch is pressed for Preset load.
