Instructions
Create an acid house arrangement — TB-303 squelch bassline.
Acid house is a subgenre of house music born in Chicago (1985-87) defined by the Roland TB-303 bass synthesizer with its distinctive squelchy, resonant filter sweeps. Key characteristics:
TB-303 bassline: monophonic, sequenced 16th notes with filter cutoff sweeps (open↔closed), accent and glide (slide) between notes. The signature "squelch" sound.
909 drum machine: 4-on-floor kick, open hat on offbeats, clap on 2&4, ride cymbal
125 BPM, 4/4 time
Minimal, hypnotic, repetitive structure with gradual evolution
Often in minor key with chromatic bassline movement
Creates 3 tracks:
Drums (track_index): 909-style — kick on every beat, clap on 2&4, open hat on offbeats, closed hat on 16ths, ride on quarter notes
Bass (track_index+1): TB-303-style 16th note pattern with chromatic movement, octave jumps, and accent patterns. Notes have varied velocity to simulate filter envelope.
Lead (track_index+2): Sparse, hypnotic stab on beat 1 of every 4 bars, minor key pad-like sustained note
Default key: A minor (classic acid key).
