• Comb -
This simulates a comb filter with a positive feedback loop - but without feed forward - ideal for flanger and phaser
types of effects. Set the cutoff frequency of the second peak with the Freq knob and the resonance amount with
the Reso knob. The difference between “Comb +” (see above) and “Comb –” is in the position of the peaks in the
spectrum. The main audible difference is that the “Comb –” version causes a bass cut.
• Resonator 1,2 and 3
The three Resonator algorithms contain formant filter tables that simulate various body resonances (multi-
peak+notch filters). Set the position in the formant tables with the Freq knob and the resonance with the Reso
knob.
• Envelope 4
This is a special mode where you can manually draw your own filter curve in the Envelope 4 window. You then con-
trol the cutoff/center frequency with the Freq knob and the resonance with the Reso knob. See “Using the Enve-
lope 4 curve as a Spectral Filter curve” for information on how to draw your own filter curves.
•User Wave
This utilizes a filter generated from FFT analyses of the external sample you have loaded in the User Wave section
(see “The User Wave and Mixer section”). Transpose the formant up/down in the frequency spectrum with the
Freq knob and change the filter’s position in the sample with the Reso knob.
q To create a classic “vocoder” effect, load a vocal/speech sample in the User Wave section. Then, set the Freq
knob to 50%, the Reso knob to 0% and the KBD knob to 0%. Then, have one of the Envelopes modulate the
Reso parameter using the Modulation Bus (see “The Modulation Bus section”). Create a positive ramp (in-
verted sawtooth) envelope and set the Reso modulation amount to 100%.
Freq
D Set the cutoff/center frequency of the currently selected Spectral Filter type.
Reso
D Set the resonance amount of the currently selected Spectral Filter type.
Frequency Modulation
D Turn the Kbd knob to set the keyboard tracking amount.
At 0% the filter is static and doesn’t track the keyboard at all. At 100% the filter tracks the keyboard 1 semitone
per note. At values above 0% you can also see the filter curve move sideways in the Spectral Filter Display
depending on where on the keyboard you play.
D Click the Frequency Modulation Source box to bring up a menu of the available modulation sources.
The “Inverted” sub-menu contains inverted variations of all modulation sources.
D Set the modulation amount with the Frequency Modulation Amount knob.
D Turn the Velo knob to control the Frequency Modulation Amount from Keyboard Velocity.
q If you want other modulation sources or scaling options, use the Mod Bus, see “The Modulation Bus section”.
The Harmonics section
The Harmonics section offers extensive modulation possibilities of the partials of the signal. For most algorithms the
partials’ characteristics is displayed in the Spectral Filter display, see “Spectral Filter display”.
