How to update the Vongon Polyphrase

Download the latest firmware zip from the Polyphrase section of the Vongon support page and unzip it. Power on Polyphrase while holding down both footswitches: the TRIG and ECHO LEDs blink slowly when the pedal is ready to load firmware. Play the firmware .WAV file into the IN L jack from a phone, computer or audio interface, with all notification sounds silenced. While loading, the TRIG LED blinks quickly for 5-10 seconds, then the ECHO LED blinks once, repeating until the load is complete. If both LEDs blink quickly the file could not be read: power off, lower the playback volume and try again. Polyphrase restarts automatically when done; count the TRIG LED blinks at power-up to confirm the installed version.

Just for reference. For complete and up-to-date instructions, always refer to the manufacturer's official firmware page.
