Shakil,
I don't have a TYROS to post a sample of it's sounds. I only had one at my store for a few hours several weeks ago. The information I post is from information I get in my conversations with product managers that work at Yamaha US. As I read these posts and see questions or opinions, I contact my friends at Yamaha to get answers to as many questions as I can.
