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.
• Avoid changing the position of blocks within the chain.
• Use multiple blocks when placing the effects (don’t change the TYPE within the same block).
• Use 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.

The same chain is used for both patches, both before and after switching. The settings of the effect used before switching are placed in parallel with the settings used after switching.

Using STOMPBOX

Your preferred settings for each effect can be saved as a “STOMPBOX.” You can select these saved settings and use them to create your sound just as though you were connecting compact pedal effects. The STOMPBOX data is common to all patches; this means that all patches using the same STOMPBOX can be edited simultaneously.

USING THE UNIT SAFELY

Concerning the Auto Off function

The power to this unit will be turned off 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 Off function). If you do not want the power to be turned off automatically, disengage the Auto Off function (p. 9).

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 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.

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 fingers pinched

When handling the following moving parts, take care so as not to get fingers, toes, etc., pinched. Whenever a child uses the unit, an adult should be on hand to provide supervision and guidance.
• Expression pedal (p. 12)

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 firmly 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.

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 fire or explosion)
  • Telephone-line ground or lightning rod (may be dangerous in the event of lightning)

Additional Precautions
