I just heard from Yamaha again, in response to another email I sent them (they always respond the same or next day). The USA people do not know why it is taking so long, but I was told the only bug that I have that will be corrected on the new chip is remembering the fingering mode.
They will not admit that the Karaoke Girl and Speedy Mouse settings are bugs. Instead they gave a work-around that must be saved to a User Memory. This is not satisfactory because you must manually set the Vocal/Harmony balance, so you can't simply toggle the effect on and off. If you do, the Main vocal won't be heard.
