Hello everyone. I just purchased a Korg O5R/W. But it still contains the previous owner programmed sounds. Well how can I reset the module so I have the Factory Settings back?

Do you have the O5RW manual? If so, go to page 107
5A Preset Data Load. this is a Global Mode function. Memory protect must be OFF. The page is 05A Preset Data Load OK? Move cursor to OK and press the ^ key. All factory settings will be loaded. Hope this helps. mrjazzy
