Wow ..what an eye opener in this comparison..
I think I prefer the Tyros4 in this sound comparison..
Clearly..you can tell the samples for the most part are similar, but the Tyros5 is swamped with effects..to a point they are over done..
Initially, when I heard the first demos, the overall sound was better on the Tyros5...thanks in part to mastering and new effects..
This gave the guitars a great sound (amp similators)..
The Tyros4 is clearer..the Tyros5 lost it's clarity..Clarity was not a strong point with Yamaha to start with...
Listening to other demos of the Tyros5, the effects on the "ensemble" drove me crazy with the pulsating volume and attack...virtually useless in any music application ..live..
You folks with Tyros4's better rethink your "upgrade" to the Tyros5.
This comparison can only hurt sales for that company..they must have a lot of Tyros4 to move out.
