Keyboardmania

Keyboardmania (alternately KEYBOARD MANIA, and abbreviated KBM) is a rhythm video game created by the Bemani division of Konami. In this game up to two players use 24-key keyboards to play the piano or keyboard part of a selected song. Notes are represented on-screen by small bars that scroll downward above an image of the keyboard itself. The goal is to play the matching key when a note bar descends to the red play point line. The arcade cabinet has two screens - one for each player.

There is also a simulator called DoReMi Mania, which uses *.pms files. However, players can use a MIDI-to-pms converter to simplify editing.
