You can use it to back up the settings of the TD-17, as well as to save the songs you want to play or record with the song player, and also to save files you want to import with the user sample function.
- Before using an SD card for the first time with the TD-17, you must format the SD card.
- Files that you want to play using the song player (WAV, MP3) must be placed in the SD card's root folder (the top level).
