For what you describe, it appears that you effectively want to turn
'local control' of the Polaris off.

Assuming your 'MIDI out' and 'MIDI in' are otherwise OK and you just
want to essentially turn 'local off'.

The main area of interest will be the settings achieved from "Lower
Function, Interface". Specifically, turn off:

Lower Function, Interface, 1 (Main Local control)
Lower Function, Interface, 2 (Link Local control)
Lower Function, Interface, 3 (Sequencer Local control)
