How to update the Faderfox PC4

Install a SysEx tool (SysEx Librarian on Mac, Bome Send SX on Windows) and download the PC4 .SYX firmware file from the Updates section of the PC4 page. Hold down the right SHIFT key while plugging in the USB cable and release it when the yellow LED blinks: the PC4 is ready to receive. In the SysEx tool select the 'Faderfox PC4' MIDI output, load the .SYX file and send it. The red LED is lit while data is received; when the transfer is complete the new firmware starts automatically and all LEDs go off. If the yellow LED is still blinking, send the file again.
