Thanks Steve for researching this further.

Agreed, Yamaha has produced and sold more Pianos and Keyboards than ANY other Manufacturer. That being said; The reason they have done this is not because you have stuck to a 'standard' Key size of 160mm to the Octave but because your Keyboards and Pianos are a step ahead of the competition IMO in quality of sound and giving the customer a boat load of features at a reasonable price. As you know, the Korg PA 80's individual Key width size is roughly 2mm wider than, let's say, the Tyros's are. In fact that holds true for all of Yamaha's Arranger Keyboards. I have played the PA80 and I can tell you from personal experience that I felt more comfortable playing on the PA80 than on my PSR 2000. First off you don't have to be so concerned and worried about where your fingers are going to land on the Keys. There is more freedom of movement because of the wider keys, and a more relaxed playing style because of it. And like Fran said, even his Roland G1000's Keybed is 1" inch longer overall in length; which again translates to about 2mm's wider per Key. So there are other Japanese Keyboard Manufacturers that ARE providing their customers with these wider Keys, not just Korg. All kidding aside about the Italian 'connection' regarding Korg, let's take Korg as an example. The Korg Triton does have these wider Keys and of course we all know that the Triton/Pro/Studio flies off the shelves. Could it be that one of the reasons many Musicians purchase the Triton over lets say the Motif series is because of the larger Key size? I would tend to believe they do.

The reason I keep coming back to Yamaha is because of their superior acoustic sounds. But I would have bought a Korg Triton in a heartbeat if their acoustic sounds were better or as good as my new Motif ES7 and one of my major deciding factors in doing so would have been the wider Key size that the Triton has. I can live with smaller Keys but I would prefer not to. That's all I'm saying to Yamaha, is that increasing the width size of your Keyboard's Keys would draw an even larger portion of potential customers into your fold IMHO. Besides, 'standards' are made to be broke if in doing so they benefit not only the end user but also improve and increase Yamaha's customer base (in satisfied customers and MORE customers), and an even greater share of the Keyboard and Piano Market.

Best regards,
