Combining third and fundamental, at AF, should not produce a rough note. 
  It should produce a string-like tone rather than the flute-like done 
from just the fundamental.

If you are getting any low frequency beat, it means the signals are not 
harmonically related.

(I think you would need an awful lot of third harmonic to shift much 
from flute to string.)
