A 24-track album where Indian classical ragas collide with trap beats, singing bowls ring over 808 sub bass, and a mellotron flute recorded on magnetic tape in 1967 plays alongside wavefolded oscillators that didn't exist until last week. Sitar arps shred at 140 BPM. A string quartet gets ambushed by drum & bass. Five vocal synths simulate auditory hallucinations. A piano tells the story of a psychotic break — from stability through spiritual seeking into chaos, despair, a hymn, and recovery.

The tuning systems span equal temperament, just intonation, and shruti (22 microtonal divisions per octave). Reference pitches range from standard 440 Hz to 432 Hz. Keys range from G major to Eb minor. Tempos from 40 BPM ambient drone to 140 BPM trap.

Every sound is generated from code. Each track is a .py file — a Python script that defines instruments, notes, rhythms, effects, and structure using pytheory. There are no samples, no DAW, no pre-recorded audio. The music is the source code. Run it and it renders to audio in real time — sine waves, saw waves, FM synthesis, physical modeling of sitars and mellotrons and singing bowls, all computed from math and played through your speakers.

Usage

uv sync
uv run play

On first run, you'll be prompted to render all tracks to WAV (parallel, ~3-4 min). After that, playback is instant.

Interactive player — animated track picker with album order:

uv run play
uv run play tracks/the_temple.py

Picker controls:

Key	Action
↑/↓	Navigate (wraps around)
Enter	Play track (from WAV cache if available)
r	Render selected track to WAV
a	Play all tracks in album order
R	Render all tracks (4 parallel workers)
q	Quit

Playback options:

uv run play tracks/acid_reign.py --from 17 --to 32                   # measure range
uv run play tracks/the_temple.py --from-time 3:30                     # seek to time
uv run play tracks/ghost_protocol.py --solo arp,kick                  # solo parts
