Hi. There is only one sound font with the Lite version and it is permanent. That is the same as is on the v3 Obsidian sound board. Is called the Obsidian Default. With the v3 you could load another sound font on to replace the original or use the silent font, but not both at the same time. If you want sound and mute on your saber, you will need to purchase the v4. If you can, it's well worth the extra cost as it has 7 different sound fonts plus the silent one.
