If you were using the matching Yamaha speaker system for the Tyros then that is why it sounded crap, this Yamaha speaker system has always made every Tyros sound crap, and who ever let these speakers get out to market should have got a serious reprimand a long time ago.
Use a quality speaker system and you will hear the Tyros 3 sing.
Hope this helps
