My Song Specific Patch has some keys that don't make sounds

Sunday Sounds Song Specific Patches are designed differently than generic patches. Not every note on your keyboard will make a sound, each patch is programmed very intentionally with certain sounds on particular keys. 

We program these Song Specific Patches with chord triggers and various sound layers across the keyboard as well as inside the mod wheel. One keyboardist is now able to play many parts with just one patch, easily switching between sections of the song by just using the mod wheel.  

Watch the demo video and free full length tutorial on the song patch's web page to learn where the layers and parts are so you can play it quickly live without guesswork.
