[sdiy] Waveshaper update

[harrybissell]

hmmm let me take my shoes off (counts toes) and do the math  :^P

but seriously folks... the overall effect of the pulser is similar to a
resonant
filter... as you sweep upward, the resonant er... bumps ??? get closer
together.

So there is a law of diminishing returns with the pulser... the more
pulses the more
it starts to sound like a resonant filter with the center frequency all
the way up.
