Well, here's one more. . .
Tonight my friend Dean and I played a nursing home Octoberfest. He normally plays a Korg or Ensoniq keyboard but tonight he went off and left his "wall wart" power supply for the Korg at home. He only plays piano sounds (plus live fiddle) when we play together, so we borrowed a PSR2000 from my other friend, Hank. Everything sounded great and went great.
On the trip home I asked how he liked the Yamaha. Dean commented that the keys were too small and that he kept hitting the cracks and hitting two notes at once.
He does not read this forum (doesn't have a computer) and I had never mentioned this subject to him.
I thought it was pretty ironic that he noticed the difference. I supposed having played pianos, Korgs, etc., for 40-some years, and never having played a Yamaha much he could FEEL the difference.
He did remark that the key size would keep him from considering buying a Yamaha, although he didn't mind the touch and loved the sounds.
