PROFILE
Roger B. Dannenberg
Worked extensively on the music-computing/amads repository, delivering robust features for music notation analysis, score comparison, and cross-format I/O. Focused on Python and JavaScript, the work included modernizing MIDI and MusicXML import/export, enhancing timing accuracy, and implementing browser-based and notebook score visualization. Emphasized code quality through comprehensive testing, CI/CD improvements, and detailed documentation. Integrated libraries such as MIDO, music21, and prettymidi to expand compatibility and reliability. Refactored APIs for clarity and maintainability, improved error handling, and streamlined contributor workflows. The engineering approach prioritized data fidelity, extensibility, and reproducibility, enabling researchers and developers to build reliable, scalable music analytics pipelines.

Jun 1, 2026June 2026: Delivered core improvements in MIDI I/O, score timing accuracy, and documentation stability for music-computing/amads. The work tightened cross-format interoperability, expanded test coverage, and reduced reliance on a single MIDI backend, enabling safer extensibility and faster onboarding. Key outcomes include a default shift to MIDO for MIDI import/export, support for zero-duration notes in exports, enhanced time-unit handling across formats, improved measure timing for multi-staff scores, and a more stable docs site.

May 1, 2026May 2026 (2026-05) monthly summary for music-computing/amads: Implemented notebook-based music score visualization with integrated I/O workflows, restructured IO to dispatch at high-level by format and preferences and expose low-level conversions, enabling clean, notebook-friendly score displays and image generations. Delivered comprehensive notation import/export enhancements including improved handling of clefs and ornaments, grace notes export, and clarified pitch naming; refactored the Clef module and expanded tests to cover ornament behavior (with caveats for Partitura). Fixed critical MusicXML input issues (tied notes resolution) and introduced notes_compare() to facilitate score-difference analysis, plus remove_overlap() to eliminate unison overlaps across voices. Improved score timing fidelity with better duration calculations, padding of pickup measures, and corrected time maps; added tests for time signatures and maps. Completed documentation updates for event handling and external references. These changes contribute to higher data fidelity, more reliable notebook visualization, and stronger test coverage, enabling researchers to reproduce musical analyses and streamline data pipelines.

Feb 1, 2026February 2026: Delivered key features and reliability improvements for the AMADS project. Implemented display and I/O enhancements for musical scores with cross-format support (PDF and MuseScore), and performed substantial cleanup of the read_score/write_score utilities. Strengthened CI and testing reliability by conditioning test runs on available dependencies (R, LilyPond), suppressing GUI apps during tests, and updating configuration to skip tests when dependencies are missing, resulting in more stable CI across environments. Expanded tonal analysis capabilities and R scripting utilities, including improved pitch-class distribution handling, integration of self-organizing maps for tonal analysis, and new R script helpers with better module organization. Outcome: clearer, more usable score I/O, faster-safe CI cycles, and enhanced analysis capabilities enabling more robust music analytics.

Jan 1, 2026January 2026 performance summary for music-computing/amads: Delivered a new Musical score comparison module with enhanced IO for MIDI/XML import/export, boosting interoperability and data handling. Established default readers/writers (pretty_midi for MIDI, music21 for XML) and hardened IO with broader test coverage and configurable IO warnings, increasing reliability of data pipelines. Also stabilized cross-version compatibility and test reliability across Python versions. Addressed Python 3.10-related test issues by converting numpy floats to Python floats, fixed a merge-induced demo break (amads.utils/core.utils integration) that affected 334 tests, and implemented robust key number validation to avoid floating-point edge-case issues. Enhanced documentation, CI/CD workflows, and code quality checks. Added typing_extensions, improved mkdocs build stability, and updated test infrastructure to run with temporary test files. These changes improve maintainability, accelerate onboarding for contributors, and reduce risk for users relying on accurate score IO and cross-version demos.
