Well, it really wasn't a lemon, it was technically the FIRST one in the U.S. I got it directly from a Korg rep, who didn't know anything about it. He had only had it for a couple of days and it had not been taken out of the box.
I had it for about a month, and it sounded really bad. I sold it, and THEN they issued a complete OS update that supposedly addressed most of the issues I had with it.
I use midi files on two or three songs when they are requested, which isn't often. Sometimes I do NY, NY, that way, but sometimes do it with styles. I generally do Suspicious Minds with a midi file. I'm too lazy to set up styles for most songs with tempo changes. Actually I had a great Suspicious Minds style, but I don't remember if it was for a Yamaha or Ketron kb.
