11.1.1.1 The Pitch

The pitch is determined by the oscillation frequency. You can set the frequency of the oscillator

with 2 controllers:

The tuning parameter ([FREQUENCY]), which allows you to tune the oscillator by semi-

tones in a range of 5 octaves.

The fine tuning parameter ([FINE]), which finely tunes the oscillator upwards by a semi-

tone. This parameter gives a bit more life to your sound when you use several oscillators

simultaneously, due to difference in frequencies between the oscillators.

It is the waveform which determines the harmonic richness of the audio signal.

On Origin, 5 waveforms are available:

The sawtooth presents the richest audio signal of the 3 waveforms (it contains all of the

harmonics at decreasing volume levels in high frequencies). Its sound is ideal for brass

sounds, percussive bass sounds or rich accompaniments.

The square possesses a more "hollow" sound than the sawtooth (it only contains odd

harmonics) but none the less, its rich sound (notably in low frequencies) can be used for

sub-bass sounds that comes out well in the mix (the square oscillator is often set an

octave below the sawtooth), wood sounds (clarinet, if the square signal is a little

filtered), etc.

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). This pulse width variation translates to a spectrum

modification, resembling a waveform change.
