Caution when performing the update
  • Never apply this update data to any product other than the KATANA. This update data may destroy the data or system program of other products.

  • We regret that we are unable to answer questions regarding the update procedure using this system program. Please perform the update responsibly, following the directions given in this document.

Getting the update file
Please open/extract the downloaded "katana_sys_v102.zip" file on your computer to get the two update files named "ROMINFO.TXT" and "KATANARM.BIN" in the "katana_sys_v102" folder.

Procedure for the update
  • You must not rename the extracted files.
  • Never turn off the KATANA's power while the update is in progress. Otherwise the system program or the KATANA itself may be destroyed.
Please install the extracted system program files into your KATANA according to the following procedure.
  1. Adjust the [ MASTER ] knob to minimum.
    * Do not connect the KATANA and the computer yet.
  2. Turn the POWER switch on while holding down both the [ CH1 ] and [ PANEL ] Tone Setting buttons.
    The indicators for the [CH1] ~ [CH4] buttons flash.
  3. Connect the computer to the KATANA's USB port by a USB cable.
    The indicators for the [CH1] through [CH2]/[CH4] buttons stop flashing and stay lighted, and a "BOSS_KATANA" drive appears on the computer screen.
  4. Open the BOSS_KATANA icon.
    "Removable Disk (*:)" may appear instead of the BOSS_KATANA icon.
  5. Copy (drag and drop) all the files included in the "katana_sys_v102" folder into the "BOSS_KATANA" icon.
    * Do not copy the "katana_sys_v102" folder.
  6. Disconnect the BOSS_KATANA from the computer.
    With Windows 10 / Windows 8 / Windows 7
    Right-click on the "BOSS_KATANA" icon in My Computer (or the "Removable Disk (*:)" icon) and execute "Eject."
    With Mac OS
    Drag the "BOSS_KATANA" icon to the Trush icon in the Dock.
  7. Disconnect the USB cable.
    The [PANEL] button flashes.
  8. Press [ PANEL ] button to start the update process.
    While the update is in progress, the "EFFECTS" indicators light up.
  9. When the update has finished, the "EFFECTS" indicators slowly flash simultaneously.

    This completes the update operation. The new system program runs at the next startup.
