Rhodes Chroma Polaris

hi folks,
I just passed a Ploaris for a lump sum of EURO 600.-.
I'm thinkin' about gettin' this beauty but since I have not the room 
for 3 keyboards, I need to know if I can get rid of my NORDLEAD 2
in order to place a POLARIS on that particular stand.
I used the nord as a master, since my prophet reponds to every midi 
message, no matter what channel (when keyboard is on Midi out!)
So, is it possible to switch Local on/off for using polaris as a midi 
master keyboard (without responding to notes played on other midi 
instruments when connected to Midi out).
thanx out there in advance.
