Ross what kind of Nord do you have? There's a file in the Apps / Templates section
here that might allow you to do just what you want. Sez:
"
PolyMonomachine-patch for the Nord Modular G2 - This is a patch for the Nord Modular G2 that makes it possible to play the Monomachine "polyphonically" when not in poly-mode (e.g. use 3 channels on the Mono, get a 3 note polyphonic synth and still have 3 tracks for mono-synths or FX left). Read the textpad in the patch for more info"
