Another game in Konami's Bemani series. Cancelled at 3rd Mix. The controller used is a two-octave Yamaha keyboard for each player, witch a pitch lever on the left or right side. Not as hard as Beatmania IIDX, but still a lot of fun. Links to Guitar Freaks and Drummania up through Guitar Freaks 6/Drummania 5.
"Keyboardmania is a fun game."
