SO, what is the VIBRATO/CHORUS section and what is the difference between the two modes?
This section of the Reface YC can apply a variety of undulating effects to the sound. This feature is often utilized to create subtle to prominent wavering and wobbling effects. It could also be used to create a sound with a vibrating motion effect for electric organs that did not have a rotary speaker device.
For switching between vibrato and chorus to apply different types of undulating effects. Simply press down the side corresponding to the effect you wish to use.
The Difference Between Vibrato and Chorus...it's subtle.
VIBRATO is an effect in which the pitch is raised and lowered. In an American tonewheel organ the traditional parameter setting options were either V1, V2, or V3.
In an American tonewheel organ, the "CHORUS" effect is created by mixing the "VIBRATO" (pitch shifted) signal with the straight (non-pitch shifted) or "dry" signal. The amount of Vibrato signal included in this combination is known as the CHORUS depth. The traditional parameter setting options were either C1, C2, or C3.
The Reface YC actually gives you 4 Depth settings when either CHORUS or VIBRATO is selected, controlled by using the VIBRATO/CHORUS [DEPTH] slider. Moving this slider all the way down turns off the effect.
Below are two recording of a brief musical example. ROTARY SPEED is set to OFF. The WAVE selection is set to H, Footage settings are full out for 8' and 4' PERCUSSION is set ON is set to type B and LENGTH is set to the third notch, and also a little REVERB is added. Notice how the percussion is accentuated by theVIBRATO effect too. It has more effect on it, the longer you set the LENGTH.
The first recording is without VIBRATO, the second one with VIBRATO, set to the third notch.
Below are two recording of a brief musical example. ROTARY SPEED is set to OFF. The WAVE selection is set to F, Footage settings are set about half way for all drawbars, PERCUSSION is set to OFF, and a little REVERB is added.
The first recording is without CHORUS, the second one with CHORUS, set to the third notch.
