The fact that AFG has to even ASK whether Ketron or Yamaha can play ON Bass chords pretty much exposes his ignorance about arrangers in general...

ALL arrangers for pretty much the last ten years or so have been able to play ON bass chords (slash chords, Bass Inversion, whatever you want to call them). Especially MOTL and TOTL arrangers. They are an integral part of music, absolutely essential to performing many different types of songs, and also to having true 'pianostyle' chord triggering. The fact that this BASIC function has been left off the MS since its' inception, and appears to not work correctly even on the third party software style players, relegates its' usefulness as an arranger to the same level as a toy Casio.

It's all well and good to gush about the advanced things it CAN do, but perhaps we ought to be paying more attention to the basic things it CAN'T?

This was Dom's mistake from the beginning. Rather than START with a fully functional arranger, and ADD the VSTi capability, he started with a VSTi player, and tried to shoehorn it INTO an arranger. And failed miserably, I hate to say. If you can't play simple chords like C/E, what's the POINT?
