VOCAL
RANGE
Use this
control to
select the
range of the
track you
will be processing. Choices include soprano
voice, alto/tenor voice, baritone/bass voice and
instrument (a general setting for anything that
isn’t actually a vocal).
Matching the appropriate algorithm to the
input results in faster and more accurate pitch
detection and more accurate pitch shifting and
modeling.
To select vocal range, click on the Vocal Range
pop-up and then select the desired range from
the pop-up list.
NOTE: Choosing the wrong Vocal
Range (or just forgetting to set it
at all) can result in compromised
performance. Pay attention.
VOICE DESIGN SECTION
The following three controls allow you to
create the basic vocal characteristics of your
voice.
Shift Pitch
As its name
suggests, this
control is used
to shift the
pitch of the
input voice
either up or
down.
MUTATOR
Evo’s pitch shifting automatically includes
formant correction (i.e., it preserves the
resonant characteristics of the original voice),
however you can further modify the vocal
characteristics using the Throat Length and
Throat Width controls described below.
The range of the control is four octaves — two
octaves up and two octaves down. The control
is calibrated in 48 discrete steps of a semitone
each.
Since an octave is equal to twelve semitones,
the values of this control are equivalent to the
following musical intervals:
1 = minor 2nd
2 = major 2nd
3 = minor 3rd
4 = major 3rd
5 = perfect 4th
6 = aug 4th/dim 5th
7 = perfect 5th
8 = aug 5th/min 6th
9 = major 6th
10 = minor 7th
11 = major 7th
12 = octave
13 = minor 9th
14 = major 9th
15 = minor 10th
16 = major 10th
17 = perfect 11th
18 = aug 11th
19 = perfect 12th
20 = minor 13th
21 = major 13th
22 = minor 14th (rarely used)
23 = major 14th (rarely used)
24 = 2 octaves
To adjust pitch shift, click on the knob and
move the cursor up to turn the knob clockwise,
or down to turn it counterclockwise. The
numeric display will indicate the number of
semitones shifted.
Command (Mac)/Control (PC)/Option (Pro
Tools) clicking on the knob will reset it to its
default value of 0.
Throat Length
This control uses the vocal tract modeling
technology from THROAT to modify the vocal
characteristics of the input voice by actually
