Hey SMachine thanks for the info. I was convinced that the comparison between these two great synths doesn't really have big difference. I like my CS1X. It is usable for some applications but again it still has some limitations. As I compared with Korg N5/EX the Korg has more features than both CS1x/CS2x combined for almost the same amount if I go upgrade my CS1x to CS2x. I just bought my CS1x and I cannot get a full refund of the amount that I paid for it. The store wants to take it as trade-in for the value of $100.00 (no way!!!) Anyway thanks for your reply. -Dan
