"Conclusion
I really can not fit in all the features, sound, styles and everything that is going on in the Tyros 4 as it really is simply so powerful. I think the are a few simple ways to sum it up. I believe anyone who hears this keyboard and questions if it is better than a Tyros 3 can not hear what everyone else can hear. It simply blows the Tyros 3 away. After 2 years of development I would not have thought such changes could have happened but Yamaha have done it again. My advice is to get your wallet ready as you will struggle not to want one"
