Hi Jose,
As a Tyros 4 owner that upgraded from Tyros 2 to Tyros 4 over six months ago, I fully echo Al and Randy's sentiments.
I continue to be blown away by theTyros 4's awesome live sound and still love playing it "more than ever".
have I mentioned that I am now a T4 owner?
That's great news !
and If you're like me, you're gonna love and appreciate your Tyros 4 "even more" over time.
Tyros 4 is truly an amazing instrument !
Congratulations Randy!
