Gamechanger Audio posts Mac firmware update instructions for AUTO pedals

March 24, 2025 · 2 sources

Gamechanger Audio published a README PDF with the full firmware update instructions for Mac for its AUTO series pedals, dated 27th March 2025, on its Auto Pedals Firmware updater - MacOs page. The page also carries a separate driver installation guide, "How_to_Install_Driver-Mac-MARCH-2025.pdf"¹.

The Mac page states a special procedure for pedals with serial numbers below 415, which it says were manufactured until February 2025 (02/25). Those units require the AUTO M-Type USB MIDI driver for firmware updates and for macOS USB-MIDI detection, according to the page. It says pedals from later batches need no driver on macOS: "Pedals from later batches (manufactured from 03/25) do not need this driver on macOS."¹ The page offers separate driver downloads for Macs with M processors and with Intel processors¹.

The update runs in a web browser. The page lists Google Chrome and Mozilla Firefox as supported and says the update cannot be executed in Safari, Microsoft Edge, Brave or Opera because they do not support Web MIDI¹. Before starting, the page asks users to "prepare a suitable 9V DC center-negative power supply with at least 250 mA or higher," advises against daisy-chain power, and says to close applications that may be using MIDI, such as DAWs or other MIDI controllers¹. It also says to "have a USB-C cable ready to connect your AUTO M-Type pedal to your computer"¹.

To enter update mode, the pedal is connected to power while both footswitches are held; the dynamic LED bar shows a rolling animation to confirm the mode, and the pedal is then connected to the computer by USB-C¹. The page notes the operating system may notify that a new MIDI device has been connected, and that browser pop-ups may ask to enable MIDI sysex messages¹.

The Windows version of the page links to a separate README, "AUTO-PEDAL-FIRMWARE-UPDATE-FOR-WIN-24th-MARCH-2025.pdf," dated 24th March 2025². No price or release date for a firmware version is given on either page.
