“Vocal Designer” is a further evolution of the “vocoder.” This function was featured on the VP-550,
and is also provided on the V-Synth GT.

Vocal Designer uses cutting-edge model-
ing technology to attain a revolutionary
leap in synthesis precision, succeeding in
producing “human voice” that is incom-
parably more natural and realistic than
conventional vocoders. Vocal Designer uses
the audio from the mic to express elements
of the sound other than pitch. The pitch is
controlled from the keyboard.

Simply playing the keyboard or simply vocalizing into the mic will not make Vocal Designer pro-
duce sound. The important thing about learning to take advantage of Vocal Designer is the timing
at which you play the keyboard and vocalize into the mic. For phrases involving rapid passages,
it’s best to hold down the notes on the keyboard, and mark the rhythm using your voice.

Unlike conventional synthesizers, you’ll use the mic to control the volume. In other words, you’re
using your voice to describe the volume curve. Try using your voice to add expression to an extent
you might consider excessive.

The vocoder was invented by the physicist H. Dudley
in 1939 as a method of compressing vocal signals.
Taking advantage of this technology, the “vocoder”
was born as an instrument that let you perform melo-
dies or harmonies using a human voice. Of course,
you’re not limited to using a human voice as the audio

Taking advantage of this technology, the “vocoder”

you’re not limited to using a human voice as the audio
source—any audio source can be used. Still, since the vocoder was developed with the human
vocal apparatus as its starting point, we’ll explain how the human voice works.
vocal apparatus as its starting point, we’ll explain how the human voice works.
The human voice starts from the “vocal cords.” Except for diff erences in
the force and the pitch of the voice, and diff erences between individuals,
the vibrational waveform produced by the vocal cords does not change
signifi cantly even when diff erent sounds (such as “aah” or “ooh”) are being
produced. These sounds become intelligible as spoken words because of
various resonances produced by the vocal tract (i.e., changes in the shape
and structure of the throat and movements of the mouth) and time-varying
sounds known as “sibilants,” “fricatives,” and “nasals.” The eff ect of the wave-
form produced by the vocal cords is relatively small.

A vocoder analyzes these time-variant changes in the sound, electrically syn-
thesizes the changes in the shape of the throat and mouth (formant move-
ments), and produces sound by using these formants to modulate a signal from a musical instru-
ment (the carrier) instead of the signal from the vocal cords. “Voices” produced by a vocoder in this
way are typically closer to a robot in a science fi ction movie than to any actual human voice.
