Kb7

Keyboard 7 (kb7 for short) is a game mode exclusive to SM5. It is meant to simulate O2Jam and other 7-key rhythm games. It can only be played with one player.

Many noteskins made for this mode are either in orbular or bar form. A few arrow noteskins have been made for this mode, though.

Keyboard 7 (kb7-single)
This game mode uses seven keys: three on the left, three on the right, and a middle key (usually the space bar).
