I have owned a S910, a Tyros 3, and a Tyros 4 all at the same time so I was able to do a side by side comparison of the three. First and foremost, the S910 did not sound anything like the Tyros 4 as has been suggested. Nor did the Tyros 3 compare well to the Tyros 4. I sold the S910 and my Tyros 3 and have not once had any remorse about that.

I gig with my Tyros 4 daily and all my audiences just love the new sounds. It has been a good investment for me.
