Scanner Vibrato

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.

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.

  • 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 Soundtrack 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.”
