Mmm, none that I've seen do ;-)

What you'd get is a very aliased sinewave depending on the frequency of te sine and the LFO rate. It's a useful if strange effect, good for cyclic patterns. Feeding a squarewave in will give you a variable pulse width pulse output, and a sawtooth wave will give you a "staircase" wave. A mixture of sinewaves (think Hammond organ waves) would give you very complex patterns.

Right, must go and build an outboard S&H now...
