Wow Kenny, I tried to duplicate your problem and just couldn't quite do it. First I went into Technichord and switched Right 1 to block then on to the mixer, page 5, and ran the key shift down to a -12. Then I went back to the keyboard and listened to the nasty sound it produced, but it was awful through the three octave range I use for my right hand playing, and not just a one octave range in the middle. Tell ya what, if the advice Alex gave you doesn't help, you may need to go over your keyboard step by step, page by page to find out what isn't working. I would imagine a reset to default settings would do the trick, but apparently that isn't working. Try contacting whoever you got the keyboard from and see if they had the same problem. Maybe they just got rid of a lemon. One thing you may want to try out is to load in a style from a disk and see if it plays okay. If it does, then contact the forum again and your problem will probably get resolved. This place is good for that!
