The only reason this topic goes around in circles with no seeming end to it, is that some people refuse to believe Yamaha has legitimate reasons not to make a 76 note mid-range or top-of-the-line arranger.
Even when some people were told by a well respected Yamaha person, Steve Deming, that the reason was that the demand was not big enough, they refused to believe it.
Clearly, the bottom line is that Yamaha will not make a 76 note mid or top range arranger until the company decides it's a workable proposition, which obviously, up to now, they have not.
