A 17 minute video demonstrating comparative sounds and styles on the 'Yamaha Tyros 5' and 'Korg PA3X' keyboards. The closest selection of sounds and styles were used in order to make a fair comparison of both keyboards.

Oops I don't know what happened there but I was going to say they both sound very good and not much to choose between them in some areas but I would probably choose the T5. Even so it still wouldn't cause me to rush out and change from what I already own.
