The PWM (top) and the Square (bottom) waveforms and their respective harmonic spectrums
• The PWM (Pulse Width Modulation) is a setting that allows you to modify the
waveform cycle (or wave length). This can be done manually with the help of a knob
“PW” or by modulation (with an envelope or LFO). Pulse width variation creates a
spectrum modification that cannot be duplicated with subtractive filtering.
• The triangle wave can be considered as a very filtered (and soft) square signal. It is
very low in harmonics (odd only) and can be very useful for creating sub basses, flute
sounds, etc.…
The Triangle waveform and its harmonic spectrum
• The sine wave is the purest waveform of all. It produces only a single harmonic,
referred to as “the fundamental”. It can be used to reinforce the low frequencies of a
bass sound or as a modulation of the frequency in order to create harmonic
waveforms. This wave form is available on VCO2.
