Bc2000 (for the BCF2000 & BCR2000)

Hello,
I was wondering if anybody knew how to connect the BCR2000 directly to a synthesizer...What i mean is No computer interface. So the out goes from the BCR2000 to the IN on the synthesizer and the In goes from the BCR2000 to the synth.
Right now I am working on mapping some of the more "useful" parameters in the Korg Prophecy. I guess I am a little confused by the "so-called" "Manual".
Which "modes" should use for this, and is this the best way to utilize the "Learn" function?
Thanks in advance,
David
