I think the 'Big Mac' analogy would only work IF people were still buying TOTL arrangers like they used to. Frank and George have both alluded to low high end arranger sales being the norm, right now (despite what you would infer from this place! ). Watch McDonald's drop the Big Mac like cancer the minute it fails to make money...

And sorry, but a line is a line... If it can be recorded to a sequencer (that's how they made the demo's, right?) it can be recorded to a style track. But when Yamaha basically NEVER add new features by upgrade (unlike most everybody else), don't hold your breath
