🚧 Known Issues

None currently - implementation just started.

🔗 Dependencies

Completed: - C++17 standard library - No external dependencies (header-only)

Future: - JSON library (for preset system) - considering nlohmann/json - XML library (optional, for DAW compatibility)

👥 Team

Current: 1 developer active Needed: 2 developers for parallel work on TIER 2-3

📝 Notes

  • Base infrastructure is solid and RT-safe
  • Parameter smoothing is production-ready
  • State management needs DAW integration testing
  • Focus next on completing state management before moving to oversampling
