Sorry Guys. It seems I "may" have hooked up to the Yamaha site whihc referred to the Tyros "3". But it had me in a panic.

Here's the link for what I saw:

http://usa.yamaha.com/products/musical-instruments/keyboards/arranger_workstations/tyros/?mode=model

What caught my eye the most were the words "Tyros" and "Discontinued".

I sent an email to Yamaha about it, and they replied back that the Tyros 4 was a "current" model.

My Bad......
