And while we’re at it, we might as well turn the triangle wave into a sawtooth for that nice buzzy-bass sound. Then we can turn the fat sawtooth into a much brighter sounding pulse wave ...

See: COMPLEX TONE, FOURIER THEOREM, HARMONIC SERIES, SINE WAVE. Compare: GRANULAR SYNTHESIS, SOUND SYNTHESIS. Successive approximations of a sawtooth wave by addition of harmonics with amplitude ...
