Good post, problem with the 3000 is so little memory, the sx900 is the way to go now unless the S975 is considerably cheaper in your country, if you had the 900 then probably no need to load voices from other instruments, my experience with older Keyboards is that you can only load some ‘sweet, cool or live voices.’
Why not sample your own voices, I’ve just done a violin, wish I had more time to make many more of my own voices, I think it’s the way to go cos the PSR,s have come full circle, what else can they add to the next model, the styles are excellent, just need some new voices now and again,
