[sdiy] Better waveforms of our nature

[Richie Burnett]

Parabolic waveform sounds like a sawtooth passed through a gentle (1-pole) lowpass filter with its cutoff frequency turned down, right down, well below the fundamental of the note.

The Parabolic is the integral of the sawtooth, as the triangle is the integral of square.
