I doubt you need to defend the Yamaha Ian, or use your subtle "marketing spin" that does seem to appear in posts that MAY be actually criticising an aspect of a Yamaha Arranger, as I seriously do NOT think you will lose one sale because it
"Marketing spins" even subtle ones, certainly aren't needed to sell Yamaha products...I never use them myself.

I am truly looking forward to my demo
YAMAHA S950 just to play around with that
cool vocal canceling feature.
