[qupte]It's a piece of cake to remain the market leader when you have capabilities that no other arranger has. Basic, fundamental features. But that barricade has been broached. The walls are starting to crumble. And Yamaha, without a dominant technological edge, may have to reconsider the process of only making improvements in new models, when their competitors are doing it for FREE.[/quote]

Having owned the Korg I certainly cannot claim the Korg has caught up with the Tyros 3 on any appreciable level. They are DIFFERENT. IF you prefer the Korg sounds you like the Korg. If phantom power on a keyboard is a plus you like the Korg,(personally I would not trust a keyboard pre amp to be very good). If a dumbed down early generation TC HElicon harmonizer engine is your cup of tea you like the Korg, 76 keys....again Korg. Upgrades are great for Korg users. It keeps Korg from having to design a new keyboard, Updates are far less expensive, Especially if they do not have enough technology ready to create a whole new keyboard,

On the other Hand Yamaha HAD to create a new board simply because of the physical additions. Even SA2 required two new buttons.
How can Korg claim SA2 type voices when they have not added the samples necessary to create them (400 SPECIFIC to the voice) samples per SA2 voice)

But the bottom line ultimately is what comes OUT of a keyboard. What the end user hears, That's why I decided on the Yamaha. But sounds are subjective and features are not. The keyboard with the most features does NOT win if the ultimate sound is not acceptable to the creative musician generating their ideas.
