There is an another version of this presentation with better quality sound and video:

I am convinced, the top down keyboard view of your video gives truely insight in the players capabillities..
He truely shows the quallity of the T5 , not only does it sound nifty and lean in the hands of a good demonstrator. But this man brings out a mean and gritty live sound.
It confirms that the T5 truely is the allrounder thats great in all aspects of music... This comes so close to why i love certain aspects of Korg instruments.
