This document details the various effect controls available on the Yamaha E-10AR Electone, including Upper Sustain, Manual Balance, and the Upper 8', 4' Sustain selector. It describes how these controls modify the sound of the upper and lower manuals to create specific musical textures.
This continuous control allows you to set the reverberatory effect to any degree of strength as the music requires.
It works with bass voices (except Bass Guitar) to provide cutoff effects from lingering to pizzicato.
The sustain effect is called forth for only 8' and 4' tones, with length set by the upper manual sustain control.
