If you listen to a Yamaha Tyros 2 and a Tyros 4 I hear a Yamaha.
Actually, you are correct...I find the Tyros2 and Tyros4 have the same
overall sound. The Tyros3 sounded quite a bit different to me (and many other Yamaha players).
However, the Tyros4 has a lot more features, and many more new sounds (including SA2-which are not on the Tyros2) when compared to the earlier instruments. Plus, it has a faster processor than T2 and T3.
Hopefully the
PA2Xpro to PA3Xpro will prove to be as substantial an upgrade as the
Tyros3 to Tyros4.
More demos will tell the tale soon enough...let's just hope they are more professionally done, and they feature more new DNC voices.
