•Before using this unit, make sure to read the
instructions below, and the Owner’s Manual.
•Do not open (or modify in any way) the unit or its
AC adaptor.
•Do not attempt to repair the unit, or replace parts
within it (except when this manual provides
specific instructions directing you to do so). Refer
all servicing to your dealer, or qualified Roland
service personnel.
•Never use or store the unit in places that are:
•Subject to temperature extremes (e.g., direct
sunlight in an enclosed vehicle, near a heating
duct, on top of heat-generating equipment); or
are
•Damp (e.g., baths, washrooms, on wet floors);
or are
•Humid; or are
•Dusty; or are
•Subject to high levels of vibration.
•This unit should be used only with a rack or stand
that is recommended by Roland.
•When using the unit with a rack or stand
recommended by Roland, the rack or stand must
be carefully placed so it is level and sure to remain
stable. If not using a rack or stand, you still need
to make sure that any location you choose for
placing the unit provides a level surface that will
properly support the unit, and keep it from
wobbling.
•Avoid damaging the power cord. Do not bend it
excessively, step on it, place heavy objects on it,
etc. A damaged cord can easily become a shock or
fire hazard. Never use a power cord after it has
been damaged.
•Be sure to use only the AC adaptor supplied with
the unit. Also, make sure the line voltage at the
installation matches the input voltage specified on
the AC adaptor’s body. Other AC adaptors may
use a different polarity, or be designed for a
different voltage, so their use could result in
damage, malfunction, or electric shock.
•This unit, either alone or in combination with an
amplifier and headphones or speakers, may be
capable of producing sound levels that could
cause permanent hearing loss. Do not operate for
a long period of time at a high volume level, or at
a level that is uncomfortable. If you experience
any hearing loss or ringing in the ears, you should
immediately stop using the unit, and consult an
audiologist.
•Do not allow any objects (e.g., flammable material,
coins, pins); or liquids of any kind (water, soft
drinks, etc.) to penetrate the unit.
•Immediately turn the power off, remove the AC
adaptor from the outlet, and request servicing by
your dealer or qualified Roland service personnel
when:
•The AC adaptor or the power-supply cord has
been damaged; or
•Objects have fallen into, or liquid has been
spilled onto the unit; or
•The unit has been exposed to rain (or
otherwise has become wet); or
•The unit does not appear to operate normally
or exhibits a marked change in performance.
•In households with small children, an adult should
provide supervision until the child is capable of
following all the rules essential for the safe
operation of the unit.
•Protect the unit from strong impact.
(Do not drop it!)
•Do not force the unit’s power-supply cord to share
an outlet with an unreasonable number of other
devices. Be especially careful when using
extension cords–the total power used by all
devices you have connected to the extension cord’s
outlet must never exceed the power rating
(watts/amperes) for the extension cord. Excessive
loads can cause the insulation on the cord to heat
up and eventually melt through.
•Before using the unit in a foreign country, consult
with your dealer, or qualified Roland service
personnel.
Before using this unit, carefully read the sections entitled: “USING THE UNIT SAFELY”and “IMPORTANT NOTES.”These sections
provide important information concerning the proper operation of the unit. Additionally, in order to feel assured that you have gained a
good grasp of every feature provided by your new unit, this manual should be read in its entirety. The manual should be saved and kept
on hand as a convenient reference.

starting the Write procedure.
FORMANT Slider
Formants are fixed frequency regions of
emphasis that are an important element
in determining how a voice sounds. This
slider adjusts the formants. Raising the
slider produces a voice character that
soundsas if the vocal cords havebecome
‘smaller.’Lowering the slider produces
a voice character that sounds as if the
vocal cords have become ‘larger.’
PITCH Slider
This slider adjusts the pitch of
the voice character. The pitch
can be adjusted over a range of
+/- one octave.
MIX BALANCE Slider
This slider adjusts the volume
balance between the generated
voice character and the original
input sound. As the slider is
raised (toward the EFFECT end
of the scale), the generated voice
character will become louder.
Bank Buttons / Bank Indicators
These buttons are used to select memory banks; they switch between the
Preset bank and the User bank.
Preset bank: Thisbankcontains preset voice characters. It is not possible
to re-write the contents of these memories.
User bank: Voice characters that you create using the sliders and the
ROBOT button can be stored in these memories.
PEAK Indicator
This indicator lets you check the
microphone input level. If the
indicatorlightsfrequently,lower
the input level by adjusting the
INPUT LEVEL knob located on
the rear panel.
* The PEAK indicator will light 6
dB below the clipping point (the
level at which distortion will
begin).
* If the PEAK indicator lights too
frequently, the proper effect will
not be obtained.
BYPASS Button / Bypass Indicator
This button switches the bypass function
on/off.
When bypass is on, the BYPASS indicator
willlight, and the voice character and reverb
will be turned off so that the input sound is
output without change.
If you use the REMOTE jack to turn off the
voice character (while leaving the reverb
unaffected), the Bypass indicator will blink.
REVERB Slider
This slider adjusts the
volume of the reverbera-
tion sound.
Selecting Preset Memories
You can choose from five voice character types as appro-
priate for your musical or performance situation. The voice
character memories will be given settings of the selected
type. At this time, the contents of the USER bank will also
be re-written.
If All Memory Type is selected, you will be able to freely
modify the settings of the PRESET bank just as with the
USER bank.
(Procedure)
1. Turn the power off.
2. While holding down the button for the desired type,
turn the power on again.
3. While the Preset indicator and the User indicator are lit,
press the WRITE button.
The voice character memories will be given settings of
the selected type:
{ [BANK]: Standard Settings }
{ [1]: Vocal Applications with reverb }
{ [2]: Vocal Applications with non-reverb }
{ [3]: Narrations / DJ Performance Settings }
{ [4]: Animation Character Settings }
{ [ROBOT]: All memory types }
Main Features
A vocal effector that independently controls
basic pitch and formants
When pitch is shifted using a conventional pitch shifter, the
formants (regions of spectral emphasis determined by the
size of the vocal cords) are also shifted. This means that
raising the pitch produces a “chipmunk voice,”as if the
vocal cords had become smaller. Conversely, lowering the
pitch produces a “giant voice,”as if the vocal cords had
become larger.
The VT-1 controls basic pitch and formants independently,
allowing a variety of voice characters (characteristic types
of voice) to be created.
Special effects using the ROBOT button
The ROBOT button fixes the vocal pitch to produce a
special effect like that of a robot speaking.
Memory Function
Voice character settings can be stored in memory. At the
touch of a button, you can select User voice characters or
Presetvoicecharacterstoswitch between a variety of sounds.
High-Quality Reverb
The on-board reverb is of a quality that rivals dedicated
reverb processors; the ideal reverb for your vocal part is
always be available.
REMOTE Jack
A REMOTE jack is provided, allowing you to turn the voice
character function on/off with a foot switch, without
affecting the reverb.
Hints for voice input
–Input only a single voice. If several voices are input, the
VT-1 will not operate properly.
–Be sure that sound from a speaker does not enter the
microphone you are using. This will have the same
effect as if several voices were input to the unit (i.e. the
VT-1 will not function properly).
–We recommend that you use a unidirectional micro-
phone; speak or sing as close to the microphone as
possible.
