one more thing to check.....
If you started out in a performance and then hit the program button to select a catagory of sounds to try out, you might find that you have funny effects like echo on every sound. This is because the effect used in the performance is now on every sound you try. I would suggest changing the mode from style play to program at the top left of the keyboard. This way you can try out all the sounds with the correct effect. Or, you could pick a performance that sounds ok with it's effects and then select the program button, as Manuel has suggested while in the style play mode and just change the right hand voice.
