Scanner Vibrato Effect
Scanner Vibrato simulates the scanner vibrato section of a Hammond organ. The Scanner
Vibrato is based on an analog delay line, consisting of several lowpass filters. The delay
line is scanned by a multipole capacitor, which has a rotating pickup. It is a unique effect
that cannot be simulated with simple LFOs.

Modulation Effects
You can choose between three different vibrato and chorus types. The stereo version of
the effect features two additional parameters—Stereo Phase and Rate Right. These allow
you to set the modulation speed independently for the left and right channels.
The stereo parameters of
the mono version of the
Scanner Vibrato are
hidden behind a
transparent cover.
• Vibrato knob: Use to choose from three Vibrato positions (V1, V2, and V3) or three
Chorus positions (C1, C2, and C3).
• In the Vibrato positions, only the delay line signal is heard, each with different
intensities.
• The three Chorus positions (C1, C2, and C3) mix the signal of the delay line with the
original signal. Mixing a vibrato signal with an original, statically pitched signal results
in a chorus effect. This organ-style chorus sounds different from the Final Cut Pro
Chorus plug-in.
• If the C0 setting is chosen, neither the chorus nor vibrato is enabled.
• Chorus Int knob: Sets the intensity of a chosen chorus effect type. If a vibrato effect
type is chosen, this parameter has no effect.
• Stereo Phase knob: When set to a value between 0° and 360°, Stereo Phase determines
the phase relationship between left and right channel modulations, thus enabling
synchronized stereo effects.
If you set the knob to “free,” you can set the modulation speed of the left and right
channel independently.
• Rate Left knob: Sets the modulation speed of the left channel when Stereo Phase is set
to “free.” If Stereo Phase is set to a value between 0° and 360°, Rate Left sets the
modulation speed for both the left and right channels. Rate Right has no function when
in this mode.
• Rate Right knob: Sets the modulation speed of the right channel when Stereo Phase is
set to “free.”
