but those demos have actuially done the Korg PA damage. You cant go head to head with the Tyros at the same venue and sound as mediocre as they have and hope to build up interest at a later date. This was veru bad marketing if it was intentional. I actually dont think the Korg will sound any better when compared to the Tyros 4. I have heard enough for me to come to the conclusion that Korg lost this round to yamaha in terms of sound and realism.
