if you need a quick and dirty hack to this end, you could always run 
your cv source into a vco, the oscillator into your soundcard, and the 
signal into fiddle~, tweaking things from there to clean up and map the 
results.  it helps to make a quick "device driver" abstraction to this 
end.
in the long run, however, i wouldn't stick with this.  it's flaky and 
very cpu-inefficient for what it does.  i just mention it because it 
can be thrown together in a few minutes if you just need a 
proof-of-concept demo of something.
