Origin oscillator
This oscillator is a special “low CPU cost” Origin oscillator. This module offers very good sound
characteristics for a low CPU charge. You can use it for a very “big” preset including lots of audio
modules.
The Origin oscillator
•
The Pitch:
The pitch is defined by the oscillator frequency. You can set the frequency with 3 controllers:
-
The |
Range
] selector determines the fundamental frequency expressed in feet. 32’ brings
the lowest audible frequencies; 2’ brings the highest audible frequencies. The “LO”
setting lets you use the oscillator as a low frequency oscillator (LFO) to modulate other
parameters.
-
The [
Fine
] knob allows you to tune the oscillator more precisely. This can be used to
create detuning effects.
-
The [
Coarse
] knob adjusts the frequency of the oscillator in semi-tones. This knob ranges
from minus 2, to 2 octaves above the fundamental frequency.
•
The waveforms:
The waveforms define the sonic characteristic of the oscillators sound.
-
The [
sawtooth
] presents the richest audio signal of the waveforms. It contains all of the
harmonics at decreasing volume levels in high frequencies. Its sound is ideal for brass
sounds, bass sounds or rich lead and pads.
-
The [
square
] possesses a more «hollow» sound that the sawtooth. It only contains odd
harmonics with lower amplitudes for higher harmonics. This waveform can be used for
sub-bass sounds that comes out well in the mix (the square oscillator is often set an
octave below that of the sawtooth), wood sounds (clarinet, if the square signal is a little
filtered), etc.
-
The [
triangle
] can be considered as a filtered (and soft) square signal. It contains only odd
harmonics at very low amplitudes. Use this waveform for example for sub basses and flute
sounds.
-
The [
sine
] is the purest available waveform. It contains only one harmonic referred to as
the “fundamental”. Use it for example to reinforce the low end of a bass sound or as a
modulation source in FM routings.
-
The [
white no
] (“white noise”) waveform produces acoustic energy across a broad
spectrum of frequencies with no discernible “fundamental” or harmonic signature. For
this reason, the noise module is used to create different noises like the imitation of wind
or special effects.
-
The [
Width
] knob allows you to manually modify the waveform cycle of the square wave.
This feature is only available when the square waveform is selected.
