 New 1 November 2021

press the reset twice with USB connected, copy the firmware file to the folder that pops up, it will confirm and the window will close automatically.

The firmware is now unified for F8R and XVI, to identify the device as XVI, DIP switch #4 must be switched to ON

THIS REQUIRES OPENING THE UNIT TO ACCESS THE DIP SWITCH, please contact Michigan Synth Works if you need assistance with opening the device.

THE DIP SWITCH IS NOW DEPRCIATED, ALL FUNCTIONS IT SERVED ARE NOW DONE VIA WEB EDITOR.  The ONLY function is serves now is to identify the unit as 16 channel instead of 8: if only 8 channels are showing up in the editor that means you did not switch DIP channel #4 to on.  Mid 2021+ Devices do NOT have this switch



Firmware update procedure:  Connect the Mini USB to your computer and press the blue reset button on the back of the module twice (quickly), it is accessible through a small hole in the desktop version.  A new drive will appear on your computer, simply copy the firmware file to that drive (it will give you a warning about copying a file without properties).  The drive will disappear once the file is copied and the module will reboot with the new firmware.
