Shepard
: this wave has only octave separated partials, perfect for organ or clear
sounds.
•
Alien
: a spectrum halfway between noise and metal with a slight pulsation.
Partial Modifiers
The partials produced by the oscillator can then be transformed by a stack of up to five
modifiers A, B, C, D and E. The modifiers are applied in sequence and can modify the
levels of the partials, their pitch or both. Each modifier can operate on a subset of partials.
Here is the list of available modifiers:
•
Level – Equalizer
: this is the basic modifier as it lets you boost or cut partials as a
classic parametric equalizer but with the added possibility of modifying only even or
odd harmonics.
•
Level – Harmonic Mix
: remove harmonic or inharmonic partials.
•
Level – Noise
: add a time varying randomness to the existing partial levels.
•
Level – Low Pass 12dB
: apply a low pass filter with a 12 dB/octave slope to the
selected partials.
•
Level – High Pass 12dB
: apply a high pass filter with a 12 dB/octave slope to the
selected partials.
•
Level – Feedback
: apply a feedback comb filter to the selected partials.
•
Level – Limiter
: limit the level of the partials to a certain level by applying a soft
clip to their level.
•
Pitch – Tune
: tune the partials to a different fundamental frequency.
•
Pitch – Scale
: scale the partial pitch away or towards a center frequency.
•
Pitch – Harmonize
: detune the partial pitch away or towards the nearest harmonic
frequency. Very handy to transform an inharmonic wave form into an harmonic one.
•
Pitch – Noise
: add a time varying randomness to the existing partial pitch.
•
Combined – Repeat
: Repeat the low frequency partials across the spectrum.
•
Combined – Mirror
: Mirror Repeat the low frequency partials across the spectrum.
•
Combined – Randomize
: Shuffle both levels and pitches.
•
Combined – Duplicate
: Create detuned copies of the partials.
A more thorough description and documentation on the partial modifiers is available in a
dedicated chapter.
Filters
After the partial modifiers, the wave form can be modified furthermore with two multi-state
filters in series featuring resonance. This is classical territory if you know subtractive
synthesis but the filters operate directly on the partials without touching the phase. Here is
the list of filter modes:
