The point is making the jack labeled "Sine" on your oscillators to
actually produce something that sounds and looks like a sine wave.

There is way too much distortion in those dome-shaped Doepfer waves
to use them in additive patches and that dome-shape usually sounds
too synthetic as general modulators (real sine function behaviors
are *very* common in nature).

I don't have any use for yet another triangle sounding wave on my
oscillators ;-)
