Dave, if you haven't already set up some patches of your own then you can simply restore the factory settings by carrying out the initialising procedure: press the Store button when the Blue Nebula is powering up. This will copy the factory presets into the user patches. Be aware that this does clear the user patch memory so you would lose any patches you've created.
If you have patches you want to keep then you can use the Librarian software to just reset the Kon Tiki patch: run the Librarian, connect to your Blue Nebula, select the Kon Tiki patch and click the Send This Patch button. This will reset just the Kon Tiki patch.
In case you don't have the USB cable to connect the BN, you could just run the Librarian and read the settings from the Kon Tiki patch then set them on the BN using the patch edit procedure as shown in the a user Manual.
I could have simply given you the settings but, in the words of the proverb "give a man a fish and you feed him for a day, teach a man to fish and you feed him for a lifetime."
