Actually, the Tyros4 was very well received, and I have read or heard very little negativity about it. The percentage of totally satisfied users is very high, indeed.

The Tyros3 was criticized much more, and perhaps it had as much to do with the way the instrument was launched, as well as the issues that early users found (that were completely eradicated with OS updates).

The "negativity" about the PA3Xpro is mostly due to Korg's seeming reluctance to produce a professional grade demo...I'm sure they must be able to find an arranger player at least nearly as good to demo as Martin Harris with the great number of PA-series that we are told were sold.

The PA3Xpro may be a much finer arranger than we are seeing...so why the hesitancy(?) on the part of Korg to showcase this allegedly impressive instrument?

It does not make sense.
