- Add DrumLoopAnalyzer: extracts BPM, transients, key, beat grid from drumloops - Rewrite compose.py: drumloop drives everything (BPM, key, rhythm) - Bass tresillo pattern placed in kick-free zones - Chords change on downbeats matching drumloop key - Melody avoids transients, emphasizes chord tones - Vocal chops between transients, clap on dembow (beats 2, 3.5) - Remove COLOR token (not recognized by REAPER) - 90 tests passing, generates drumloop_song.rpp with 10 tracks, 20 plugins
