I came accross this guy before... (The Solitair)...but now he is demoing a LOT of unbeleivable sounds on his T4.
This is just one of MANY and I mean many great sounds and song playing. If you get this one up...then you can go to his others.
He really knows this thing and is VERY talented is an understatement. If you listen to a bunch of these demo's he calls them....I think you will be happy you did. Very inspiring to us arranger players. What more could one ask for?
I will build one of these some day, and maybe buy some of his samples if they are for sale..

Steve is, I think the best keyboad player I have ever seen/heard.

There is many in his samples demo series...all are great.

Is this really a T4? (Yes, I know it has a lower manual too)
