Overview
Introduction
The Vocalist®Live 3 Desktop (VL3D) is a powerful but easy to use intelligent
vocal harmony processor. Armed with the musIQ®harmony generation tech-
nology, the VL3D combines studio-quality audio performance, state of the art
vocal processing and an easy to use control interface.
The VL3D provides the flexibility to allow musIQ technology to automatically
generate two HarmonyVoices, to manually produce up to four HarmonyVoices
in MIDI Notes mode, or to manually define the key and scale for the Harmony
Voices in instrument-free Acappella mode. In addition, the VL3D offers Pitch
Correction, Gender Shifting, and Humanize functions too.
With 5 available patches to save harmony configurations, four vocal Pre-Effects,
pitch correction, three room sizes of reverb and a guitar tuner all packed into
a sleek and stylish die cast metal desktop form factor, the VL3D ensures an
enjoyable and streamlined harmony and vocal processing experience for a wide
range of applications.
musIQ®Technology
musIQ is a revolutionary technology that eliminates the need to program key
and scale information to generate Harmony Voices. In real time musIQ tech-
nology analyzes the Lead Voice as well as the notes, chords and key signatures
played on a guitar or MIDI keyboard and automatically generates accurate and
musically correct vocal harmonies that both complement the LeadVoice and fit
the music being played.With musIQ technology, you can focus on your singing
and playing performance and eliminate song programming once and for all.

1 2 3 4 5 6 L R
You will need to select the musIQ®Guitar mode using the
Mode button.
The VL3D must be first in the guitar signal chain to ensure proper musIQ
analysis and harmony generation. Connect the guitar directly to the Guitar In.
The Guitar Thru output can then be connected to any effects pedals before the
amp.

11
Guitar Sensitivity
While playing the guitar, the Guitar Signal Strength indicator should be green
or amber. If the Guitar Signal Strength indicator does not light when you play,
the guitar signal level may be too low and the Guitar Sensitivity should be
changed to Hi. If the Guitar Signal Strength indicator lights red, then the Guitar
Sensitivity should be changed to Lo.
To set the Guitar Sensitivity hold the Tuner button
until the new Guitar Sensitivity setting of Hi or Lo
is displayed.The most common setting is Lo Guitar
Sensitivity.
Tuner
It is important for your guitar to be properly tuned in order for the musIQ®
technology to generate the best sounding harmonies.Alternate tunings (for ex-
ample, DADGAD or tuning down) are fine, as long as the built-in tuner shows
each string as in tune. If you are using an external tuner, make sure that the
reference is set to 440 Hz.
To use the built-in tuner, press the Tuner button to
start the Guitar Tuner.The Tuner button will flash
while the Tuner mode is active. Note that for the
Tuner to work properly it needs to receive adequate
guitar signal strength, which is indicated by the Guitar
Signal Strength indicator.
As each string is individually played, the closest note to that played will appear
on the Display and the Tuner Bars will show the deviation in pitch from the
target note. If the string is in tune with the target note, the green center Tuner
Bar will be lit. Bars to the left will light if the string is flat and bars to the right
if the string is sharp.
When all strings are in tune, press the Tuner button to exit the Guitar Tuner.

12
Using the VL3D with a Computer
There are two options when using the VL3D with a computer:
The VL3D can be connected directly to a computer via its USB port and1.
used as a MIDI interface.
The VL3D can be connected to a a separate MIDI interface already con-2.
nected to a computer.
VL3D used as a MIDI Interface
When the VL3D is connected directly to the computer via USB, it acts as a
MIDI interface. Data sent into the MIDI In of the VL3D is passed on to the
computer through the USB port. Similarly, all data sent from the computer to
the VL3D is passed through the VL3D and appears at the MIDI Thru jack.
Note: When USB is connected, the VL3D's MIDI In does not pass data to the
MIDI Thru Jack

13
VL3D connected to a MIDI Interface
When the VL3D is not connected to a computer using the USB port, all MIDI
data sent to the MIDI In of the VL3D is passed on to the MIDI Thru jack.This
allows you to chain other MIDI devices, such as sound modules, to the VL3D.

14
Pre-Effects
The VL3D contains a variety of Pre-Effects to enhance your vocal sound.
Warmth
This controls the amount of warm subtle distortion from the
tube preamp amp model, adding a degree of vintage tone.
Compressor
The Compressor gives the ability to tighten up the dynamic
range of the Lead Voice. The Compressor threshold, ratio, at-
tack and release are all adjusted automatically to provide the
right amount of overall compression.
De Esser
This adjusts the aggressiveness of the De Esser suppression
of sibilant sounds that may be over-emphasized by the micro-
phone.
Noise Gate
This control defines the Noise Gate threshold for the micro-
phone input. Below the defined threshold, low level unwanted
background noise is muted and will not pass through to the
main outputs.
To collectively enable and disable all Pre Effects, press the Pre
Effects button.When lit, all Pre Effects are enabled.

15
Pitch Correct
This corrects the Lead Voice to a 12-note chromatic scale.
Use the Amount knob to set the aggressiveness of the pitch cor-
rection.
When the Pitch Correct button is lit red, Pitch Correct is enabled.
When the button is not lit, Pitch Correct is disabled.
Reverb
There are three selectable room sizes for the Reverb effect.The active reverb
type is indicated by the lit button.
Studio Reverb simulates a studio plate reverb. Room Reverb
simulates the natural reverb of a medium sized room. Hall
Reverb simulates the reverb of a large concert hall.
The Reverb Level knob adjusts the amount of overall reverb
applied to the mix.
When the Reverb button is lit, the Reverb is enabled.When
the button is not lit, Reverb is disabled.

16
Harmony Patches and Parts
Singers need a way to configure different Harmony
Voicings for use in different songs. To accommo-
date this, the VL3D provides Harmony Patches. This
allows the singer to specify the Harmony Mode,
Voicing, and Gender Settings in advance and recall
them when needed during a performance. There are five harmony patches.
Each harmony patch also has an A Part and a B Part. Typically this will be used
to specify one harmony setting for, say, the verse and a separate setting for the
chorus. During the song it is easy to toggle back and forth between the A Part
and the B Part with the simple press of a button either on the front panel or
on the optional footswitch.
Each Harmony Patch stores the Harmony Mode, HarmonyVoicing and Har-
mony Gender settings. Harmony Patches do not store the Pre Effects, Pitch
Correct, Reverb, Harmony Mix, Humanize or Harmony On/Off parameters.
Store and Recall a Patch
To recall a patch, simply select it using the Harmony Patch button to cycle
through the saved Patches of stored Harmony settings.
Once you have made changes to a harmony patch, you can store the changes
to the selected Patch by pressing and holding the Harmony Patch button until
the lit Harmony Patch Number flashes twice.
Note:You must make changes to the Patch location you wish to save them to
as there is no way to save changes made in Patch 1 to Patch 5.
Harmony A/B Parts
Each patch contains two independent harmony settings: Part A and
Part B. You can select between these two Parts using the A/B but-
ton on the face of the VL3D or with an optional 3-button Foot-
switch. The active Part is indicated by the bi-color LED on the Part
button. Green indicates Part A. Red indicates Part B.
Note:You must store each part individually. For example, if you store Part A to
a harmony patch, Part B will not be saved unless you select it and store it also.
