Well you can go on but I had the GW 8 and now I own a Korg PA50 which is 200 Euro cheaper to begin with. The keybed of the korg is much better and the korg have normal size keys. The Roland keys are smaller. The mp 3.If you plug a mp3 player in the Korg you have the same. Then what have the Korg. Speakers. Better and more styles. Totally editable styles and sounds. Bigger screen. Better and more effects. Sounds of the Triton synthesizer. Need I to go on?
Look I like the Roland GW8 but the Korg is much more keyboard for the money.
