Preset data can be managed on your PC with TF Editor software.
In TF Editor which is online with your console, you can drag and drop a preset item to your desktop to download a preset file. This is a good way to backup your original preset data one by one.
File name: Its default name is taken from the title of the preset on the console. Because file name and title on the console UI are independent, renaming the file does not affect to the title shown on the console.
You can also drag a preset file to the Editor and drop it to upload the file.
Two or more files can be handled at once.
Yamaha is preparing to provide new preset files from the TF web site.
