Amplitude

Amplitude is a music/rhythm game and is the sequel to 2001's Frequency. Like it's predecessor, players play songs by hitting notes on multiple tracks representing each instrument found in the song.

In Amplitude, the player controls a ship (referred to as a "Beat Blaster") moving down a path of varying shapes and lengths, containing up to six tracks. Each color-coded track corresponds to a different aspect of the song, such as percussion, synth, bass, or vocals, and contains a sequence of notes.
