Getting Ready
Connecting the Equipment
* To prevent malfunction and equipment failure, always turn down the volume, and turn o all
the units before making any connections.
* Before turning the unit on/o, always be sure to turn the volume down. Even with the volume
turned down, you might hear some sound when switching the unit on/o. However, this is
normal and does not indicate a malfunction.
* To prevent the inadvertent disruption of power to your unit (should the plug be pulled out
accidentally), and to avoid applying undue stress to the jack, anchor the power cord using the
cord hook, as shown in the illustration.
DC IN jack
Connect the included AC adaptor here.
* Place the AC
adaptor so the side
with the indicator
(see illustration) faces
upwards and the side with textual
information faces downwards. The
indicator will light when you plug the
AC adaptor into an AC outlet.

Editing: Eects
Switching patches without interrupting the sound
The GT-1000 is equipped with a new type of high-speed patch
switching system, allowing you to switch patches with minimal
interruption of the sound. The fastest possible switching is
automatically performed for each patch, and switching without
interrupting the sound is also possible.
Tips for preventing interruptions in the sound
To prevent interruptions in the sound, observe the following points
when you create the patches that are used before and after the switch.
5Avoid changing the position of blocks within the chain.
5Use multiple blocks when placing the eects (don’t change the
TYPE within the same block).
5Use parallel positioning, and switch the channel.
Example:
Switching from a clean sound that uses chorus and deep delay, to a
crunch sound that uses phaser and shallow delay.

Looper
You can record up to 38 seconds (MONO) of a performance and play back the recorded section over and over. You can also layer additional
performances with the recording as it plays back (overdubbing).
This lets you create real-time backing performances on the y.
When the play screen (p. 4) is shown, pressing the [1]–[5] switch of the currently selected patch number (example: for U01-1, switch [1]; for U01-5, switch
[5]) turns the looper on. The same switch is used for all looper operations.
Record
Recording will start immediately
when you press the switch.
At the point where you want to
loop, press the pedal to switch to
playback.
Loop Playback

Pressing the switch will switch to

To clear the phrase, hold down the
switch for at least two seconds while
stopped.
Press Twice
Loop Playback Level Setting
If you set the playback level at 100 (default value), the volume of the
performance and that of the loop playback will be identical.
If you set the playback level to a value lower than 100, the volume of
the playback will be lower than that of the performance. As a result,
the sound of the performance won’t get buried by the loop playback
sound, even if you record a multiple number of times.
1. Press the [EFFECT] button.
2. Turn knob [6] to select LOOPER.
3. Turn knob [1] to specify the “PLAY LEVEL” value.

USING THE UNIT SAFELY
WARNING
Concerning the Auto O function
The power to this unit will be turned o automatically after
a predetermined amount of time has passed since it was last
used for playing music, or its buttons or controls were operated
(Auto O function). If you do not want the power to be turned
o automatically, disengage the Auto O function (p. 7).
Use only the supplied AC adaptor and the correct voltage
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 specied on the AC adaptor’s body. Other AC adaptors
may use a dierent polarity, or be designed for a dierent
voltage, so their use could result in damage, malfunction, or electric shock.
Use only the supplied power cord
Use only the attached power cord. Also, the supplied power
cord must not be used with any other device.
CAUTION
Take care so as not to get ngers pinched
When handling the following moving parts, take care so as not
to get ngers, toes, etc., pinched. Whenever a child uses the
unit, an adult should be on hand to provide supervision and
guidance.
• Expression pedal (p. 11)
Handle the ground terminal carefully
If you remove the screw from the ground terminal, be sure to
replace it; don’t leave it lying around where it could accidentally
be swallowed by small children. When refastening the screw,
make that it is rmly fastened, so it won’t come loose.
IMPORTANT NOTES
Placement
• Depending on the material and temperature of the surface on which you
place the unit, its rubber feet may discolor or mar the surface.
Repairs and Data
• Before sending the unit away for repairs, be sure to make a backup of
the data stored within it; or you may prefer to write down the needed
information. Although we will do our utmost to preserve the data stored
in your unit when we carry out repairs, in some cases, such as when
the memory section is physically damaged, restoration of the stored
content may be impossible. Roland assumes no liability concerning the
restoration of any stored content that has been lost.
About the Ground Terminal
• If you are using the ground terminal, connect it with an external ground.
When the unit is grounded, a slight hum may occur, depending on
the particulars of your installation. If you are unsure of the connection
method, contact the nearest Roland Service Center, or an authorized
Roland distributor, as listed on the “Information” page.
• Unsuitable places for connection
• Water pipes (may result in shock or electrocution)
• Gas pipes (may result in re or explosion)
• Telephone-line ground or lightning rod (may be dangerous in the
event of lightning)
Additional Precautions
• Any data stored within the unit can be lost as the result of equipment
failure, incorrect operation, etc. To protect yourself against the
irretrievable loss of data, try to make a habit of creating regular backups
of the data you’ve stored in the unit.
• Roland assumes no liability concerning the restoration of any stored
content that has been lost.
• Never strike or apply strong pressure to the display.
• Use only the specied expression pedal. By connecting any other
expression pedals, you risk causing malfunction and/or damage to the
unit.
