Topic: What a difference a keyboard makes!
I bought a Korg SP-170 about a year ago to replace the unweighted keyboard I'd been teaching myself on, Pretty decent action, but definitely entry level. Sounded pretty nice, until I tried Pianoteq. Even through my $20 computer speakers, Pianoteq just blew the built-in piano sounds away. I bought some decent speakers, and ended up only using the Korg as a midi controller for Pianoteq. I just sold the Korg and got a Studiologic SL-990xp. It's ugly as sin, and the controls are nearly useless, but the keyboard is a quantum leap up in quality from the Korg, and it cost a lot less. I knew I would get a better piano feel with the Fatar keyboard, but I didn't realize how much difference it would make in the sound I get out of Pianoteq. So much more control, it's like I upgraded Pianoteq along with my keyboard.
