Frequency shifting (adding each partial's frequency by an offset) isn't
the same as pitch shifting (multiplying each partial's frequency by a
ratio).

The objects hilbert~ and complex-mod~ will help you, as they helped me
when I tried to make a snare drum following that tutorial, I'll see if I
can find the patches sometime later today.
