This track uses the Namco N163 expansion chip, which allows up to eight additional channels of customizable waveforms, in addition to the standard 2A03 set.
This track also bypasses the channel hiss that is problematic with six or greater channels, as it was written before knowledge of the hiss was known, or at least implemented into FamiTracker.
The instrumentation in this album is almost indescribable, it's so different and feels like a breath of fresh air. The melodies are beautiful. ethbloom
