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). Again in this case, pulse width variation creates a spectrum modification that
cannot be duplicated with subtractive filtering.

• 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.
The
synchronization
of an oscillator with another creates more complex waveforms. If for example,
you synchronize oscillator2 with oscillator1, oscillator2 will restart a new period every time the first
oscillator completes its period, even if oscillator2 has not fully completed its current cycle (this
signifies that it is not tuned to the same tonality!) The more you tune oscillator2 upwards, the more
you will encounter composite waveforms.
In the image above, osc1 is synchronized with osc2 and tuned to with double the tonality..
