Psr s 670 multipad snag

[MaltaMystery]

Hi.. I have owned  the psr s 670 for approx 18 months. I have just ventured into programming a multipad using a preset voice... It's a simple single notes piano phrase.... But when I save and playback. It plays fine but only in every other measure.. So the first bar is good but second bar is silence... Third bar is good etc..... I researched and found that this can be corrected using the EDIT function on some models.. However the edit function on the 670's multipad creator does not seem to allow this kind of editing.... If so then does anyone know how to solve this problem..... Thanks
