Thanks to you all, for your responses. They were what I anticipated. I agree with you totally. The Tyros is an improvement over the 2100. I know, I went out and picked one up last night! NICE BOARD! Two things I noticed immediately...(1)The feel of the keyboard is MUCH better. (2) The quality of sound - of even the same voices that were on the 2100 - sound even more natural. Now I need to find a buyer for a 4 month old 2100.
