Donny,
What I would before doing the save on Songbook go to STS#2 Piano and be sure it's the chosen voice you want for STS#2
Then in Songbook go to the 2nd tab that's labeled "book edit 1" then in the middle of the screen you will see "Keyboard Set" . Usally the so called radio button is set to "All" and is colored green. At this point you need to choose the radio button under all. You should then see Piano on the screen then simply save it to whatever location you want, you could actually choose 1, 2, 3 or 4. depending on where you'd like that voice saved. Hope that helps.
Steve I have no problem assigning sounds to my STS styles etc ....... what I need is when I select a style in song book I want a certain STS sound to be already to go....hope thats clear?
