That's both a great detailed review and just plain sad!

Here's hoping Steve or someone at da big Y can help you get to the bottom of these things. It may be the OS and then again it may be something else. As I recall didn't the T1 and T3 have some of these roll out problems.

I have also wondered how Y does its beta testing. It seems like many times its the simple stuff that we see that they don't for whatever reason; lack of knowledge or lack of giging experience, cultural differences, etc.

In looking at the specs I was surprized that the T4 did not offer more over the T3. Also with the economy these days its time some of these OEMs woke up and realized their price points are way to high... that or just let the product sit on the F ing shelf until they have to discount it. When one looks at something like the Motif for LESS money...

All that said... Yamaha IS a great company and in the 25 years of on the road work using their products they have _ALWAYS_ taken care of me. IF what you say is accurrate >with repeatable steps that lead to the problem< I think that Y will come out with a OS software update in short order. Make sure you send them this report.

Great JOB and please keep us informed of what happens next.... there is strength in numbers and sharing of info!
