Firmware Update v1.1

Firmware Update v1.1

This is the release of firmware update v1.1. This update improves the sensitivity of the neck sensors. To install the update, a Windows operating system is required. For Mac, see below. Please follow these instructions:

  1. Download the firmware update here: and unzip the contents.
  2. Turn on the Misa Tri-bass (ensure the blue USB cable is NOT connected).
  3. Now connect the blue USB cable (plug marked #2) to your computer. Windows may install some drivers automatically.
  4. Connect the other end of the blue USB cable to the Tri-bass.
  5. Once you can see the blue screen on the Tri-bass touchpad, run the "install.bat" file.
  6. A "New Connection" window will appear. Select the "Serial" option and press OK.
  7. Once the transfer is complete, wait 30 seconds. Disconnect the blue USB cable.

Note: Do not turn on the Misa Tri-bass while the blue USB cable is connected to it. Doing this starts a different programming mode that is not relevant to this update. If you accidentally start this mode, then it may appear as though the Misa Tri-bass is unresponsive, stuck at the logo screen, or "off". To fix this:

  1. Disconnect the power cable and the USB cable.
  2. Unscrew the small black cover on the back of the Misa Tri-bass.
  3. See the battery plug? It has a red and black wire and a white connector. Disconnect it from the board for about 10 seconds.
  4. Reconnect it and re-assemble.

Restore / Reset Firmware

If you want to go back to the original firmware version, run the "revert.bat" file included in the firmware update package described above.
