f HUMANIZE AMOUNT
You can vary the amount of humanization for
the harmony voices. All the styles except for the
last one: TIME & PITCH were designed at middle
values to allow you to add or remove effects as
you see fit. TIME & PITCH was designed so you
can create wild special effects as you experiment
with high values.
f VIBRATO STYLE
This simulates the regular human pitch variations
we call Vibrato. There are 7 styles available in
progressively more intensity as you browse down
the list.
Like the HUMANIZE effects, each voice is treated
slightly differently by the VIBRATO algorithm so
the voices don’t all sound exactly the same.
f VIBRATO AMOUNT
You can vary the amount of vibrato intensity for
the overall style with this parameter. All the styles
were designed to be useful at middle values but
you can add or remove vibrato as you like.
f V1 to V4 PORTA
Each voice has its own Portamento time. Porta-
mento is a delayed response to the pitch move-
ment of your singing voice. It is also referred to as
“Glide” in synthesizers. The range of values equals
approximately how long the upwards or down-
wards slide will take to reach each new note. Set-
ting each voice to different values greatly assists
the illusion of other singers singing with you.
f V1 to V5 SMOOTHING
At low values, Smoothing acts like pitch correc-
tion for the harmony voices. With the voices
corrected like this, some Portamento is usually
activates the style and level set by the CHOIR
STYLE and CHOIR LEV parameters respectively.
To create a convincing choir performance, it helps
to sing legato (sustained) phrases as opposed to
staccato or melismatic riffs.
f HUMANIZE STYLE
The term “humanize” simply means the applica-
tion of processes designed to increase realism.
All harmony modes usually benefit from care-
ful application of humanization styles that make
each harmony voice respond with small pitch and
timing variations different from your voice. Each
Humanize Style configures each of the four voices
differently; Voice 1 has slightly different parameter
values than say Voice 4 in the same style but all
four voices will work together to produce a use-
ful overall effect.
The various Humanization styles consist of vari-
ous amounts of the following modifiers:
• Onset pitch events - This is also known as
“scooping” which adds a generated pitch tra-
jectory for each new note that is different than
the sung note.
• Pitch modulation - a random wave genera-
tor wobbles the pitch in non-periodic ways to
simulate even the finest singers’ pitch variation.
• Timing delay and modulation - Singers are
unable to start notes at the same time with
the exactness of a machine so this algorithm
applies slight delays to the onset of notes and
then adds modulated time variation to sus-
tained portions of notes.
• Level (volume) modulation - This effect is like
a subtle tremolo with a non-periodic or semi
random waveform that simulates the way
different singers change note volumes as they
sing.
