To download the firmware:
1. Go to https://www.redpandalab.com/downloads/#tensor
Note: There are multiple versions of firmware for the Tensor. Pedals that were made since 2019 will use the same version regardless of your operating system--prior to that, there are different packages for Mac and PC. Check your serial number to determine which file to use.
2. Download the firmware (.zip) file to your computer.
3. Unzip the downloaded file to extract the binary firmware file (.bin).
Caution:
• Do not rename the extracted file.
• Never disconnect the pedal’s power while an update is in progress. Otherwise the system software or the pedal itself may be destroyed.
Update procedure
1. Hold down the left footswitch and connect power.
2. The right LED will blink blue.
3. Continue holding the footswitch for 2 seconds.
4. The LED will turn solid blue. The pedal is now in USB Mass Storage mode.
5. Connect the pedal to the computer using a mini USB cable.
6. Open the TENSOR drive on your computer.
7. Drag and drop the firmware binary (.bin) file to the TENSOR drive.
8. After the firmware update is complete, the LED will turn solid green. If an error occurred, the LED will blink red instead.
NOTE: If the firmware update seems to stall with both LEDs still lit, eject the TENSOR drive from your computer and it should resume (move ahead to step 11). If not, retry the procedure.
10. Once you have a solid green LED, eject the TENSOR drive from your computer:
Mac: click the eject button or drag the TENSOR icon to the trash
Windows: right-click on the TENSOR icon in My Computer and select “Eject”
11. Disconnect power.
Troubleshooting
If the left LED blinks red, disconnect power and try again. If you continue to have problems, please email support@redpandalab.com.
Please tell us which LEDs are on, what type of computer, and which operating system you are using.
