Why strive for perfection? You’ve already found possibility.
8-Beat Studio turns moods, keys, scales, and genres into full songs. Pick a mood, choose a vibe, and let the harmony-aware Song Builder generate drums, bass, chords, melodies, and solos—then sequence, mix with rule-based "AI-style" presets, record multitrack, and export a finished track. It all runs in your browser. No installs. No accounts.
