A good player will get the best out of their instrument no matter what it is; however there is no reason for a keyboard player to emulate the same as a Sax player etc. as its palette is much greater, (Unless all you want to do is recreate a specific instrument) so you can create your own sound and be individual, (Rather than sounding the same as every other Tom, Dick & Harry out there) so make your own sound (That’s what professional keyboard players do) and become unique rather than trying to make your keyboard sound like something it isn’t. (In the old days you could recognise a player by his style (No matter what keyboard he was playing) but these days with arrangers those that know a small amount about arrangers just say oh that’s a Yamaha or that’s a Korg, with the player being an irrelevance)
