This page contains instructions and links to the latest firmwares. Please be aware that not all firmwares are compatible with all board revisions. To determine which board you have you can remove the backplate of the pedal and on the main circuit board you will find the text "xyz rev ###", where ### will be h, i, j, k or l (all lower case letters, the 'l' is not the numeral one '1').
- A windows based computer.
- A usb A to usb mini B cable
- A count to five pedal.
- STM Dfuse software available (free) here .
The latest for Rev h/i (0.931h).
The latest for Rev j (0.931j).
The most current firmware for rev k and l (0.963k). It fixes a bug in mode 1 that was introduced in 0.962k. See this post for details.
Outdated firmware for rev k and l boards (0.962k). This firmware adds one new feature, see this post for details.
Outdated firmware for rev k and l boards (0.96k). This firmware adds some new features, see this post for details.
What shipped with rev k and l boards up to July 1, 2016 (0.95k). This firmware adds volume control to each head in mode 3. You can access it by holding the q switch down and turning the respective DIR knob. This firmware shipped with the most recent run, but is newer than what shipped on teh September 2015 run.
An alternative firmware for rev k and l. (0.941k). This firmware does not have the volume controls for DIR knobs in mode 3 that were added in 0.95 but does change the way the soft footswitch works. Instead of holding the footswitch to record in modes 2 and 3, you press and release it, and recording will start when the button is released. You can stop recording and initiate playback by holding and releasing the button again. Tapping will reset/erase the recording as usual. No change to footswitch behavior in mode 1.
The firmwares are only for the boards specified above and at this moment not all boards support the latest firmware so please make sure you download the correct firmware for your board revision, you can identify your board revision by taking off the backplate and reading the silkscreen label on the main pcb.
- A Philips head screwdriver.
- Unzip and Install the STM Dfuse software and restart your computer if necessary.
- Locate and load the program "Dfuse Demo (v3.0.4)". It should have the following path by default "Program Files (x86)\STMicroelectronics\
- Disconnect power from your count to five.
- Remove the back plate by removing the 4 screws.
- Locate the mini USB jack which is beside the large IDC header close to the bottom of the pedal.
- Connect the usb cable to your computer and the pedal.
- Apply 9V power to the count to five. The usb cable must already be in place before powering up in order to communicate with the computer. Ie make sure steps 6 and 7 are done in the correct order.
- Windows should now detect the device. Allow windows to automatically find the driver online, it may take several minutes the first time you connect the pedal to your computer.
- Once the device is properly initialized go back to Dfuse Demo and click on the "Choose" button that is under the "Upgrade or Verify Action" section of the window (lower right). A window opens and you must select the firmware. Locate the firmware you downloaded with the .dfu extension from step 5 of the prerequisite.
- Click on the "Upgrade" button just beside the "Choose" button you used in step 9. A warning will come up about how the device is plugged in in dfu mode and it is impossible to know if the file is correct for the device... Click yes to continue anyway. Two things should happen in the progress bar now, first an erase, then an upgrade. Once the upgrade completes, disconnect the USB cable and power, exit Dfuse, then replace the backplate. The unit is now updated.
