Hi Gary,
Yamaha may be good at sending out surveys, but do they take note of what the people have said?

Just consider the "Wish Lists" on most of the keyboard forums (one of them, at least, was being monitored by Yamaha). I have made many suggestions myself on these but can't recall any of these requests being acted upon except one (Yes, they finally produced a 76 note Tyros after many years of begging).

I don't have time to go through these requests but the same things have been requested by many Yamaha users and have still not been implemented.

My Tyros 4 was an expensive keyboard, the Tyros 5 even more so and I would expect more then a few very small improvements for that kind of money.

Just my personal view but I know there are many other T4 owners who share it.
Best wishes,
Tony
