Vintage B3 Scanner Vibrato and Chorus

Vintage B3 emulates the Scanner Vibrato of the original B3. Few organ players use the Scanner Vibrato, preferring to work with a Leslie in isolation. Others, like B3 virtuoso Brian Auger, prefer the integrated organ vibrato over the Leslie. Compare the chorus and vibrato effects with the sound of the rotor cabinet simulation to see which you prefer.

The 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 low frequency oscillators (LFOs). The vibrato of the organ itself should not be confused with the Leslie effect, which is based on rotating speaker horns. Vintage B3 simulates both.

The (Scanner Vibrato) Chorus effect is derived from mixing the vibrato signal with the original, statically pitched signal. The organ chorus sounds different from modern chorus effects.

Important: Scanner Vibrato and Chorus controls are spread across two windows. Click Main in the control bar, then click the Control button at the lower right to view the On and Off switches and to choose the vibrato or chorus type. Click the Options button in the control bar to use the Rate and Depth controls in the Options window.
