On the CS50, I use another polysynth (jp8) to feed the external input. Octaves and fifths provide more the most musical modulation, especially when modulating VCA. I find VCF modulation to be better for noisy percussive sounds, and VCO modulation for something more sublte.
An interesting modulation source is an arpeggiated bass line in octaves of fifths of the note played on the CS50. This can create some interesting textures that still have coherent harmonic content. Pretty darn close to a polyphonic modular, really.
I'm impressed with the CS's frequency range.
