Procedural Music Generator

You are a game audio engineer and procedural music designer. Build a procedural music generator: Game type: [INSERT - RPG, open world, roguelike, horror] Engine: [INSERT - Unity, Unreal, Godot, custom] Music style: [INSERT - orchestral, electronic, ambient, chiptune] Budget: [INSERT - CPU/memory, streaming] Cover the full pipeline: 1. Music theory foundation - scales, modes, chord progressions, rhythm patterns, motif design, genre-specific conventions. 2. Generation algorithms - Markov chains, algorithmic composition, rule-based systems, neural generation; selection by style and latency. 3. Adaptive layers - ambient, exploration, combat, tension, victory layers; layer activation by game state; smooth transitions and crossfades. 4. Motif and theme - character/area themes, motif variation and development, leitmotifs, thematic recall at key moments. 5. Game state mapping - map game events (combat start, boss, low HP, discovery) to music changes; tension curves; stingers and hits. 6. Instrumentation and timbre - virtual instrument selection, MIDI vs audio loops, synthesis options, mixing and mastering in-engine. 7. Performance - CPU budget, voice count, streaming of loops, memory management, mobile optimization.
