Saw (Sawtooth)

The Saw (sawtooth) wave derives its name from its shape, and is used to create a

trumpet or violin sound. Since it contains all harmonics in the spectrum, it produces a

full, rich sound. When used with the

Pulse Width

function, increasing the even harmon-

ics can raise the pitch to a maximum of a full octave.

Pulse

The Pulse wave is used to make woodwind (clarinet-type) sounds. Its spectrum is sim-

ilar to a sawtooth wave, but since every second (even-numbered) harmonic is missing,

the waveform contains only odd-numbered harmonics when

Pulse Width

is set to "64".

Saw2 (Sawtooth2)

The spectrum of the Saw2 wave is created by a sawtooth wave combined with a pulse

wave, and therefore is slightly different than the Saw wave. When the

Pulse Width

set to 64, the shape of the wave is the same as Saw. Even if you increase the even-

numbered harmonics by the Pulse Width, the basic pitch remains the same.
