Wait untill you hear the SD9PRO,and yes the Tyros is good,but the Ketron gives you the live feeling what an musician will hear,Tyros is better when you play smf,but i want play live and than the Ketron is top,the arrangements are the best,the audiodrums sounds as a real live drummer with all his breaks.And the basline is superb.And offcourse the live audioguitars.
