The sinusoid waveform
-
The
noise
signal spectrum has all frequencies at an equal volume level, often referred to
as “white noise”. For this reason, the noise module is used to create different noises like
the imitation of wind or special effects. White noise is the richest of noises. Pink noise is
also regularly present on synthesizers. It is less rich in the high frequencies than white
noise. The audio output of noise can also be used as a modulation signal (especially when
strongly filtered) to create random cyclic variations.On hard-wired synthesizers, the noise
module is either integrated into the oscillator (its audio output being placed to
compliment the waveform outputs), or within the mixer directing the signals towards the
filter.

Synchronization
The
synchronization
of an oscillator with another creates more complex waveforms. If for example,
you synchronize oscillator2 with oscillator1, oscillator2 restarts 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 can encounter composite waveforms.
