LFO voltage?

This is very true. If you think how pitch modulation is applied to stringed
instruments in the real world, the pitch is only modulated up from its
non-modulated pitch. I'd imagine that a rectified sine wave as the modulator
would sound most "familiar" in terms of real-world pitch modulation. So
positive uni-polar modulation makes sense here. But then we don't always
want sense...
