For this game, I chose not to take advantage of DirectMusic's adaptive harmonic abilities, such as ChordMaps or Chord Tracks. The simple harmonic structure of the music did not merit the extra production time that it would have taken to make it function well within the design. Frequent or complex harmonic and chordal shifts did not fit the aesthetic of electronica music. I created the music's harmonic or chordal changes directly in the pattern editor. Harmonic changes occur when moving from one groove level to the next, which correlates to a row being cleared or added.
