No updatable firmware on the Walrus Audio ARP-87
It is analog or fixed-function hardware, so there is nothing to update.
You can still add it to your rig to keep an inventory and track its used market price.
Connect the pedal to a Mac or Windows PC using a USB-C data cable while also powering it with a 9VDC supply. Open Google Chrome and navigate to walrusaudio.io. Log in or create a Walrus Audio account. Select the ARP-87, go to Firmware, choose the available firmware version, and follow on-screen instructions. Windows users may need to install the DFU driver available on the firmware update screen.
