Before the knocker box came into being, (Or style engine as it�s called today) players used to be able to play any song anybody wanted with no problems, whether on piano or organ, so to say you need masses of styles to play a large repertoire of songs is poppycock.

If you do use multiple track styles, make them sound like you, as otherwise you will sound the same as everyone else out there. (Remember great players are known for THEIR style of playing, not the keyboards style)

Also remember that styles are there to enhance YOUR playing not the keyboard manufacture, which is why they are secondary (And some would even say irrelevant) to the performance.
