  // This test focuses on the logic of tracker_update, not the full audio generation pipeline.

  // Each pattern has multiple events which trigger voices.

  // For this test, we assume voices triggered at 0.0f are still active for a short duration.
  // A more robust test would check for specific spectrograms or mock synth.
  // For now, we expect voices to still be somewhat active or new ones to be triggered if there's overlap
