/*
Schemawound track for Waxen Wing's "Give Me A Sine" compilation.

Compilation Description: All songs written using ONLY sine waves in their creation. All oscillations, modulations, lfo's, envelopes, etc, use only sine waves. No samples or outside source audio were permitted on this releases, unless of course the samples were of pure sine waves. Download includes full 8 panel artwork and extensive liner notes on each piece written by each artist.
