e^(ix)

The equation

eix = cos x + i sin x

What the equation decides

Where the tumbi stands. It circles you: left-right is cos, front-back is sin, and it turns faster as the track builds. Headphones help.

This is the notation of what the code plays. Stereo copies and octave layers share one staff, empty staves are hidden, and timing is rounded to values you can read. Pitch bends, filter moves and the rest of what the equation does to the sound can't be written here. That part you have to hear.
