Wow, 30 of them! :-) I just need one :-) but I'll check them out. I'll likely start with the one with the newest date, as it's more likely to be made on a newer keyboard (the 2015 one vs. using the 2001 one, which was probably on a Tyros 1?!)
Thanks again - it'll be fun to see if one of these works out well . . .
