Hi there,

Please try the following:

• Press SETUP twice to go to page 2 of the setup menu.
• Confirm that the Eclipse MIDI channel is correct (or select OMNI)
• Press the MIDIMODE soft key and confirm Prog Change is ON
• This should be enough settings for the Eclipse to receive PC messages and you should see a dialog on the screen when it is loading a new preset
• You can go to SETUP page 3 > Maps to edit the PC maps, and try Map 1 and reset to default if you still have issues
