Having switched from T2 to PA800 last November I have found that one of the better features of the Korg is the ability, at the touch of a button, to silence all of a style except drums and bass. This enables one to be creative when you want to be and idle when you don't. I use a midi controller board to play left hand sounds and styles. It never quite worked with the Tyros as the left hand sounds always seemed weak and not the same as the identical sound selected for right hand. Not so with the PA800. Whether selected for right or left hand use the voices sound the same and with them used across the full width of both keyboards I find I can get a much richer variety of tone. Particularly in the lower registers.
