Sure that's fine if you feel that way, but I don't think you would have a good understanding of the ergonomics because you don't know the function of all the buttons and their locations on the keyboard.

That's why I said he's playing the keyboard his way and it's his choice. Every mediastation user looking at that video would know he's not using the dedicated buttons for switching sounds. This very subject of how he changes sounds has come up on this forum before actually.

It's purly his choice of how he likes to work.

From an ergonomics point of view the program up and down buttons are the two closest buttons to your right hand, so there's nothing really wrong with the layout. It's just how he's using the keyboard.
