Rhodes Chroma Polaris

Hi there.  I have had the polaris for a couple of years and didn't 
have the factory patches.  I saw the demo on youtube and was very 
excited to hear them finally.  I was looking for an easy way to 
transfer factory patches from the computer to the polaris via midi and 
bypassing the cassette.  Is there an easy way to do this?  After all 
that I've been researching there doesn't seem to be an easy way.

Cheers
