Antigravity (agy) Prompt Recipes

Copy-paste prompts for autonomous multi-track production in Antigravity.

1. Generate 124 BPM Melodic Techno Track with Acid Bass & 909 Drums

Techno Production

agy "Set project tempo to 124 BPM in C Minor using live12_song_set_scale. Create a drum track with a 909 Core Kit, inject 4-on-the-floor kick with 16th hats having velocity deviation. Add a second track with Drift, set resonance to 0.45, drift to 0.35, and write a 16-step syncopated acid sub bassline. Then add a third track with Wavetable, route LFO 1 to Filter 1 Freq with depth 0.45, and start transport playback."

2. Comp Arrangement Take Lanes & Apply Werckmeister III Microtonal Tuning

Advanced Audio Workflows

agy "Inspect track 1 take lanes with live12_take_lane_list. Comp bars 16-24 from take lane 0, and bars 24-32 from take lane 1 using live12_take_lane_comp_region. Load the Werckmeister III .ascl tuning system using live12_song_set_tuning_system. Inspect resulting arrangement and return telemetry."

3. Slice Vocal Sample to Drum Rack & Chain Roar Mid/Side Distortion

Sound Design & Slicing

agy "Load vocal hook into Simpler on track 2, switch playback mode to Slicing, and call live12_simpler_control to slice to Drum Rack. On the new Drum Rack track, load Roar, configure routing_mode to 'mid_side' with drive 14.0dB and tone 0.65. Save project set to /Users/juancruz/Music/LiveSets/VocalChop_Roar.als."
