Ive had my used Tyros 4 for five months now having always wanted a Tyros. So I purchased one with some of my inheritance following the loss of my Father last year. I know the Tyros has been superseded by the Tyros 5 and Genos. I can say the Tyros is a great arranger now I'm getting to grips with it. And combined with my other new keyboard the Korg Pa700 they make a great combination.
