How to update the Klavis Quadigy

Download the firmware ZIP from the Klavis Quadigy product page and extract the WAV file. Connect an audio cable from your playback device to the Quadigy's CV A input. While holding the Preset and CV Matrix buttons simultaneously, power on your case — the display enters update mode. Play the WAV file at approximately two-thirds volume. A progress bar fills on screen; when complete, all green LEDs flash. Press any button to restart. If red LEDs appear, reduce playback volume and retry.

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