Root cause: build_bass_track() never received the kick_cache in main(). Second issue: kick times were WAV-relative (0-12 beats) but bass expects absolute positions (16+ beats). Added loop-duration projection to convert relative → absolute positions across clip duration. 285 CC11 events now generated in output. 302/302 tests pass.
