I think korg does not support the OW/1FD any more. so here is two suggestions.

-Get a new Korg.

-if you really want a O1/wFd so much. check this site for a used one. www.ebay.com

please correct me if they still support it as I tried to fix something on my 2 weeks Old O1/WFD and they said it is not supported. so I Sold it.
