some comment on Audrey's message, useful for others too.
W.r.t 5): Also on Tyros2 you can directly record to the hard disk and even do audio dubbing. Then when all is OK you can export it as WAV to an USB-stick for whoch is also a USB port on the front. Big difference will be: speed. T3 is USB-2 so more than ten times faster. And Tyros has a second USB on the back and there is USB-to-host. SO you can connect directly to the PC and make a full backup of Tyros HD to the PC.
The biggest change: not one but 5 DSP’s in parallel in the styles, several Superarticulation_2 and the number of Superarticulation voices have grown.
If you can arrange good speakers or a decent head phone to the PC you can listen to 45 minutes Tyros 3 music on the website I made for my dealer:
www.keyboard-centrum.nl/T3/specs.htm Now that Tyros3 comes on the market, the Tyros2 will be cheaper and many nice T2 occasions will come on the market.
