• Odd/Even knob: Set the balance between odd or even harmonics. Low values
increase the level of odd-numbered partials (1, 3, 5, 7, and so on), making the
sound more hollow. High values increase the level of even harmonics (retaining
the fundamental tone: harmonic/partial 1) to make the sound brighter and
sweeter.
• Fifths knob: Set the level of the fundamental tone and all partials at fifth intervals
(7 semitones) above it. Higher values boost harmonics 1, 3, 9, 27, and so on, with
a corresponding reduction in the levels of other harmonics. Low values have the
reverse effect and can make the sound more cutting and edgy.
• Pulse/Saw: Scales partial levels to make higher partials softer than low partials.
Loaded by default when no sample has been imported into the additive element of
the source.
• Pulse/Saw knob: Set the mix ratio between a pulse wave and a sawtooth wave,
created by summing sine wave partials tuned to a harmonic series. Turn toward
Pulse to mute even harmonics. Note that if one of the complex waveforms is
used, the Pulse/Saw knob behaves differently.
• Sync knob: Enable oscillator sync and set the pitch that the main oscillator is
synchronized with.
• Odd/Even knob: Set the balance between odd or even harmonics. Low values
increase the level of odd-numbered partials 1, 3, 5, 7, and so on, making the
sound more hollow. High values increase the level of even harmonics (retaining
the fundamental tone: harmonic/partial 1) to make the sound brighter and
sweeter.
• Tone knob: Tilt the overall spectrum from flat to steeply angled, affecting the
tonal color.
• Saw+Noise: Saw wave with noise applied to the amplitude of harmonics.
• Noise knob: Set the amount of noise applied to amplitudes of harmonics.
• Rate knob: Set the rate at which the noise value is changed.
• Smooth knob: Set a response that varies between an instant change at each new
value through to a gradual ramp over the entire time period.
• Tone knob: Tilt the overall spectrum from flat to steeply angled, affecting the
tonal color.
Additive effect 2 (pitch) parameters
• Additive effect on/off button: Enable or disable the additive effect unit.
• Additive effect 2 pop-up menu and field: Choose an effect type that is used to adjust
the tuning of different partial groups. Your choice determines the controls that are
shown.
• Beating: Allows a group of partials to be detuned to create beating effects as they
move in and out of phase with adjacent partials or to add a clangorous, atonal
character to a sound. The group of partials affected is defined by the Partial knob.
• Amount knob: Set the amount of detuning for selected partials. The range of this
knob is determined by the position of the Tuned knob.
