I do appreciate your time on this. I hear the same shrill type of tones. No body, etc. I'm sure this can be "user error". I'm a little puzzled the presets sound this bad. Could the previous owner have done something? There are blocks where there is nothing there. I would've guess there would be many, many presets made by the company. But, the way it sounds now, I wouldn't buy this unit had I known. But, I could be doing something wrong. Is there a way to download the factory presets where I can start from square one?
