Danny I hope you don't mind a different perspective.
I think this demo.. Yamaha picked on the wrong Ketron
The Tyros is thin sounding, that is why is swimming in effects..
Audya is fatter, with more clarity and definition, Unlike the Tyros it sounds live.
I think the Ketron samples are better than Yamaha.
Especially drums and bass, easily better on Audya.
I think folks would be surprised if they heard these two stripped of all effects, and listen to the quality of the samples.. Yamaha would be embarrassed.
