A somewhat fixed version of Central City from Sonic Chronicles: The Dark Brotherhood (A poorly made midi port of 3D Blast's Diamond Dust Zone Act 1).
The original used a poorly made midi that frequently got notes wrong or missed notes in general. This version somewhat fixes these while staying somewhat true to the original by avoiding simultaneous notes in the same channel. The drums have been cut down to 3 simultaneous sounds. The backing chords from the original are excluded.
