< Formants >
A formant is an important element which determine the
character of a vocal sound. It is a fixed overtone whose
location is determined by the size of the vocal chords.
Conventional pitch shifters modify the pitch in a way that
changes even the location of the formants (which by
nature do not change). For example when a conventional
pitch shifter raises the pitch, a Òduck voiceÓ is produced
as if the vocal chords had shrunk, and when the pitch is
lowered a Ògiant voiceÓ is produced as if the vocal chords
had expanded.
The Voice Transformer modifies the basic pitch and the
formant separately, allowing a variety of voice characters
to be created.

Adjust the balance between the voice character volume and
the normal voice volume.

This switch allows you to use the channel faders of the top
panel to modify the various settings of the Voice
Transformer. If this is on, channel faders 1Ð5 will control the
following settings.
* Fader Edit is valid only when you are in Effect Edit condi-
tion. In other conditions, the faders will control the vol-
ume level of each channel as usual. Also, it will fail to
operate in Auto Mix (p.17).

Channel 2:
Channel 3: C.Formant+F.Formant
Channel 4: MixBal
Channel 5: RevLevel
