58 ARTURIA – ARP2600 V – USER’S MANUAL
In the above image, oscillator2 is synchronized with the first and tuned to twice its frequency. The resulting
waveform is unique in that it cannot be created by standard synthesis techniques such as layering or filtering.
A frequency modulation ( FM ) can be created between 2 oscillators by connecting the audio output
from a first sinusoidal oscillator to the modulation input of a second oscillator. On the ARP2600 V, if
you turn the modulation rate ring, you will obtain a sound richer in harmonics.
If you introduce a
square or saw tooth signal, the result can be quickly distorted… but interesting for inharmonic so-
norities like bell sounds or special effects for example.
The noise module
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.
Also note that the audio output of noise can also be used as a modulation signal (especially when
strongly filtered) to create random cyclic variations.
