Hi Craig!
You may wish to try my frequency shifter instrument, archived at:
 http://media.dr.rhbnc.ac.uk/csound/list/msg01775.html 
You will have to replace the variables kfrqshf, ko1frq and ko2frq by a-rate
variables, say afrqshf, ao1frq and ao2frq. Then afrqshf is the modulator
input, awvin the carrier input.
