The Vocoder Plus contains three tone-generating sections: Vocoder, Human Voice and Strings, which may be independently assigned to cover the whole keyboard, or either the upper or lower half.

The String section produces orchestral string sounds that are silky and warm feeling, and most importantly, consistent throughout the entire length of the keyboard. The Tone and Attack Time of the String section can be controlled inependently, and the Release Time is hared with the two other sections.

The Human Voice section literally defies description with its uncanny resemblance to a chorus of human voices. The upper half of the keyboard contains one female and one male chorus, while the lower half contains two male choruses. There is also an ensemble effect which increases the dimension of the vocal chorus.

The Vocoder section, like our rack-mounting Vocoder (SVC-350), processes the spoken or sung human voice (program), analyzing its character and using this information to modify another musical signal (carrier). The Vocoder section uses ten analysis filters for vowel sounds, and there is also an additional filter that is used for consonants. The Vocoder section uses as a carrier signal the combined components of the Human Voice and String section
