Mark, I fully agree with you have put a great deal of effort into your Kn7.
I just received my Tyros 3 today - I will give a report for those who are interested. This is by no means putting down the Kn7, that is not my purpose. But I must say, and I say this politely those of you who may have interest are not receiving the correct information about Yamaha.
When understood, and that means binding all thoughts you have from working a keyboard like the Kn7000, and renewing your mind to a new concept the Tyros 3 is fantastic. If there were a KN8000 I would have bought that instead. If I could turn the clock back and stay with my KN7000 I would most likely stay with the KN7 because of the learning curve. After working with the Technics operating system for over ten years it came second nature to me. There was very I did not understand.
The Tyros 3 is a tool and it can not be mastered without a commitment. That is why I sold my KN7, I needed to get away from the KN7 operating system. If I did not I could not begin to master the Yamaha. In my battle I have owned two Tyros keyboards and a S900 -- and two different KN7. I found that I could not be successful working two different systems. Again, not for everyone!
Now that I have made the move I am happy I made it although the effort and commitment was steep. It is not for everyone. If anyone would like to know more about the Tyros 3 I will respond. If not this is my last post on this subject.
