VOICEDOUBLER V1.20 ADDENDUM
Introduction:
This document is an addendum to the existing
VoiceDoubler v1.00 manual detailing the new features and
factory presets available in software version 1.20.
Overview
1. Introduction to new features
2. New presets list and descriptions
New Features
VoiceDoubler’s edit menu is divided into groups indicated
by the characters in the LED window. The following
parameters have been inserted into the Pitch edit group P
and the System edit group S.
P6
Portamento Time
0-500ms in 10ms increments
Preset parameter
Those familiar with synthesizers will be familiar with the
term Portamento. Also known as Glide, this is a feature
that slows down the time it takes to change pitch from note
to note. This feature can add realism to VoiceDoubler’s
overdub voices by introducing subtle pitch differences
between the dry singers’s voice and the overdub voices. As
the singer moves through sustained note transitions, the
pitch will glide gently from note to note. No effect is heard
between sung notes that stop and start.
Many factory presets in version 1.20 use Portamento. The
Portamento setting is controlled along with the other pitch-
based parameters by the PITCH edit knob in Preset mode.
This allows you to adjust it without having to enter Edit
mode if you prefer.
In the edit menu, Portamento is expressed in milliseconds.
On sung melodies with fast tempo and wide intervals, lower
values (<100ms) work fine but on slow tempo, narrow
intervals you can use higher values.
All four overdub voices are controlled by the one
Portamento parameter value so they all will reach notes at
the same rate.
S0
Gate Threshold
Off, -60 to 0dB in 1dB increments
System parameter
The Gate parameter was added to help silence
VoiceDoubler’s overdub voices during times when the band
is playing but the singer is not singing. At these times,
VoiceDoubler searches for pitches to lock onto in order to
create the overdub effect which can cause low level
chattering. If this is noticeable in your performance
environment, the Gate can be utilized to minimize it.
This parameter will not mute the Dry Voice signal path
through VoiceDoubler if it is enabled. Also, the path from the
dry voice through the µMod effect is never muted by the
Gate.
The value of this parameter sets the threshold level
required to allow audio to pass through VoiceDoubler. At
values from say, -60 to -15dB, very quiet sounds will open
the gate. Between -15dB and 0dB, increasingly strong
signals will be required. Note that “ess” sounds and voiced
sounds are sensed differently by the gate. Higher threshold
settings that work for sung melodies may actually mute
esses so you may need to lower the threshold a few dB to
allow them to be heard.
As with most noise gate products, its effect is not perfect.
Some noises will slip through and some low level sung
passages may be muted. Gate Threshold should be re-
checked at every sound check and during performance to
ensure that every word and syllable is heard.
