Logic Pro X: Scanner Vibrato effect
Scanner Vibrato simulates the scanner vibrato section of a Hammond organ. Scanner Vibrato is based on an analog delay line consisting of several lowpass filters. The delay line is scanned by a multipole capacitor that 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 set the modulation speed independently for the left and right channels.
Scanner Vibrato parameters
Type knob: 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 different 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 effect. This organ-style chorus sounds different from the Chorus plug-in.
In the C0 setting, neither the chorus nor the vibrato is enabled.
Depth knob and field: Set the intensity of the chosen chorus effect type. If a vibrato effect type is chosen, this parameter has no effect.
Stereo Phase knob and field: 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 and field: 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 and field: Set the modulation speed of the right channel when Stereo Phase is set to free.
