Data Backup and Restore Operations

The Tone Setting saved in CH1, CH2 on the panel can be saved by
following procedures.

The PANEL Settings cannot be backed up. Therefore, in case the Main
Board is replaced or the Factory Reset is performed, the PANEL Settings
will be lost.

Items Required

•Computer

•USB cable

• MIDI sequence program (Cakewalk Sonar LE or etc.)

* Install this to the computer above.

• Driver for KATANA.

* Obtain this from the following web page, and install it on the computer just

described.
http://www.roland.com/global/

System Update Procedure

Items Required

•Computer

•USB cable

• Update file (obtained via Service Net)

Procedure

1. Hold down CH1 and PANEL and switch on the power.

CH1 and CH2 flash.

2. Connect the computer to the USB connector.
The buttons that flashed in Step 1 light up constantly, and the computer
screen shows BOSS_KATANA drive.

3. Copy the update file (*.BIN, ROMINFO.TXT) to the root folder on the
BOSS_KATANA drive.

4. Unmount the BOSS_KATANA drive and disconnect the USB cable.

PANEL flashes.

5. Press PANEL.

BOOSTER/MOD, DELAY/FX, and REVERB light up in green, and the

update starts.

While updating is in progress, BOOSTER/MOD, DELAY/FX, and
REVERB light up in order of red, green, and orange.

* Never switch off the power while the update is in progress. Doing so might make

the unit impossible to start.

Data Backup

1. Connect the computer to the USB connector.

2. Launch the MIDI sequence software on the computer, and set the MIDI

input and output device to KATANA.

3. Create two MIDI tracks (Track 1, Track 2) and input the following SysEx

data to the Track 1.

F0 41 00 00 00 00 33 11 00 00 00 00 20 00 00 00 60 F7

4. Set the Track 2 to standby for recording, and start the recording and the

playback.
The SysEx of the Step 3 is transmitted to the amp, and the amp that
received it transmits all the user data to the MIDI sequencer.

The transmission of the user data completes in several seconds.

* There are no change on the amp’s display.

5. Stop the MIDI sequencer, mute or delete the Track 1, set the Track 2 to

playback, and save the file.

The backup procedure is finished now.

6. Disconnect the USB cable.

Data Restore Operations

1. Connect the computer to the USB connector.

2. Launch the MIDI sequence software on the computer, and set the MIDI

input device to KATANA.

3. Load the backed-up file and transmit it to the amp.

The transmission of the user data completes in several seconds.

* There are no change on the amp’s display.

4. Stop the MIDI sequencer.

The restore procedure is finished now.

5. Disconnect the USB cable.

If BOOSTER/MOD, DELAY/FX, and REVERB turn green, and slowly
flash simultaneously, then the updating is completed.

* If the update did not finish correctly, then these three buttons flash in fast cycle.

6. Switch off the power.

Performing a Factory Reset

1. Hold down PANEL and switch on the power.

2. If any of the buttons light up or flash, then release your finger.

The Factory Reset starts, and BOOSTER/MOD, DELAY/FX and REVERB
light up and turn dark in sequence.

When PANEL flashes, the factory reset has finished.

3. Switch off the power.
