I can't punish Yamaha. This company is so big that anything I would or could do would be totally insignificant. But neither do I have to support or promote them, or use their products, if they do not act to rectify the situation.
The reason the Harmonizer issue is so important to me is that I am working with the guy who did "I Like Bread and Butter". The guy who did the high part is not a part of our act, so I must do it, using the Karaoke Girl setting. Now I have to take the old PSR8000 instead of my brand new 2000 if I want to perform this song.
There are other remedies, such as external harmonizer, but that shouldn't be necessary since the keyboard I bought is supposed to have this feature. It probably is not that important to anybody else in the world.
