And as the EZ 250i is still very expensive, I wonder which cheaper midi kb would work both also with ps2 and usb converter, just like it seems to be shown in this video: http://www.youtube.com/watch?v=MQ2pH...elated&search=
For some reason I'm thinking Keyboardmania 1 doesn't have support for random MIDI keyboards, only the Konami controller.
Keyboardmania II does, though.
