Vocal Transformer Parameters
The Vocal Transformer offers the following parameters.
• Pitch knob and field: Determines the amount of transposition applied to the input signal.
• Robotize button: Enables Robotize mode, which is used to augment, diminish, or mirror
the melody. See Using Vocal Transformer’s Robotize Mode.
• Pitch Base slider and field (available only in Robotize mode): Use to transpose the note
that the Tracking parameter (see below) is following.
• Tracking slider and buttons (available only in Robotize mode): Control how the melody
is changed in Robotize mode.
• Mix slider and field: Defines the level ratio between the original (dry) and effect signals.
• Formant knob and field: Shifts the formants of the input signal.
Setting Vocal Transformer Pitch and Formant Parameters
Use the Vocal Transformer’s Pitch parameter to transpose the pitch of the signal upward
or downward. Adjustments are made in semitone steps. Incoming pitches are indicated
by a vertical line below the Pitch Base field. Transpositions of a fifth upward (Pitch = +7),
a fourth downward (Pitch = -5), or by an octave (Pitch = ±12) are the most useful
harmonically.
As you alter the Pitch parameter, you might notice that the formants don’t change.
Formants are characteristic emphases of certain frequency ranges. They are static and do
not change with pitch. Formants are responsible for the specific timbre of a given human
voice.
