Chapter 10 Modulation eects 216
Scanner Vibrato eect
Scanner Vibrato simulates the scanner vibrato section of a Hammond organ. Scanner Vibrato is
based on an analog delay line consisting of several lowpass lters. The delay line is scanned by a
multipole capacitor that has a rotating pickup. It is a unique eect that cannot be simulated with
simple LFOs.
You can choose between three dierent vibrato and chorus types. The stereo version of the eect
features two additional parameters—Stereo Phase and Rate Right. These allow you to set the
modulation speed independently for the left and right channels.
Scanner Vibrato parameters
•
Type knob: Rotate to choose from three Vibrato positions (V1, V2, and V3) or three Chorus
positions (C1, C2, and C3).
•
In each of the Vibrato positions, only the delay line signal is heard. Each vibrato type has a
dierent intensity.
•
In the three Chorus positions (C1, C2, and C3), the signal of the delay line is mixed with the
original signal. Mixing a vibrato signal with an original, statically pitched signal results in a
chorus eect. This organ-style chorus sounds dierent from the Chorus plug-in.
•
In the C0 setting, neither the chorus nor the vibrato is enabled.
•
Depth knob: Rotate to set the intensity of the chosen chorus eect type. If a vibrato eect type
is chosen, this parameter has no eect.
•
Stereo Phase knob: Rotate to determine the phase relationship between left and right channel
modulations. If you set the knob to free, you can set the modulation speed of the left and right
channels independently.
•
Rate Left knob: Rotate to set 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. The Rate Right knob has no function when in
this mode.
•
Rate Right knob: Rotate to set the modulation speed of the right channel when Stereo Phase is
set to free.
