<html> <body> Hi Danny, I'm with you on exploring any and all voicing possibilities before doing something radical like changing string scale. The Yamaha GH-1 is a particularly problematic piano, and I have yet to hear one that "works" at the tenor break. I think it is a weak spot in the scale design. There may be other design flaws as well, which I would be interested to hear about, if anyone has thoughts about it.
