Keyboardmania 2ndMix is the second arcade release in the Keyboardmania series. Unlike KEYBOARDMANIA, all the songs in KEYBOARDMANIA 2ndMIX have song comments on the official website for the game. LIGHT difficulty is introduced, which is a more simple difficulty that only uses 13 keys instead of 24. NORMAL is renamed LIGHT+. PRESSURE mode is introduced, which consists of four song courses. The gauge starts at 100%, but does not recover from any MISSes, even between songs. Videos for returning KEYBOARDMANIA songs were changed to generic videos that use various KEYBOARMANIA song clips.
