Hi everyone, I know this question will bring different opinions. For those that have had the pleasure of owning or spending time with all three of these synth manufactures offerings on the arranger end, which one from first to last do you think has the most realistic sounds and why. Obviously I'm refering to the most recent models offered ex: Korg PA80-PA1x, Roland VA7-G7, Yamaha 9000Pro-Tyros etc. Ease of use is not a factor.
