Lee,

I have had no problems at all since upgrading.

Perhaps Scott Yee could share his experience, as he also has a Tyros4.

How's it going with you Lee...getting a PA3X, or are you discouraged like the rest who have heard the demos so far?

The price seems good, but what good is a decent price, if the instrument is not sounding how you'd want it to sound?

What about a Tyros4...any closer with a decision?

I am simply loving mine...it's the best Yamaha has made, by far...superb sound, and a real joy to play.
