Uncle Dave,

I played the 2100 and I thought maybe it had a slightly stiffer key feel than my 2000 does, but I also considered the possibility that the key feel on my 2k gets looser as it ages and gets played.

Either way, if there is a difference, it certainly isn't significant enough that I like it much better. It's even harder for me to get into the 2k key feel when I play it right after I've played my Motif or PA80.. For me, the key feel of the 2k is the absolute worst thing about the board. When I play it as a solo instrument ( which I do sometimes ), I control it with the Motif or the PA880 keys. Sometimes I just use it along with the PA80, and via midi I mix the sounds of the two boards to get a fatter or modified sound..
