PROFILE
Mikekirin
Over six months, contributed to the musescore/MuseScore repository by developing and refining features focused on guitar notation and import fidelity. Built enhancements for Guitar Pro import, including robust handling of string tunings and capo transpositions, using C++ and XML to ensure accurate representation of non-standard tunings and improved data integrity. Refactored core import pipelines and stabilized test suites, addressing edge cases in pitch, transposition, and guitar bends. Applied algorithm design and data validation skills to expand compatibility across Guitar Pro formats, reduce manual editing, and streamline CI workflows, resulting in more reliable score conversion and improved user experience for music software.

Feb 1, 2026February 2026: Stabilized guitar bends test data in musescore/MuseScore by removing anchor elements across multiple test files, resolving conflicts and inaccuracies in the test suite. This fix reduces flaky tests, strengthens CI reliability, and speeds up feedback for code changes (commit 816b93a6a2294633449f52647b37eeebc88cf662). Skills demonstrated include test data management, cross-file coordination, and Git-based QA workflows.

Jun 1, 2025June 2025 performance summary for musescore/MuseScore: Delivered significant enhancements to Guitar Pro (GP) import and tuning handling across GP4/GP5 and newer GP formats, with refactors to string tuning processing for robustness and correctness. Implemented standard and non-standard tunings detection and handling, enabling accurate instrument representation and smoother imports. Fixed critical GPConverter tuning and pitch handling issues, including transposition bugs and GP6 pitches import, improving import fidelity and TPC calculation accuracy. Improved MIDI program recognition during GP5 imports to ensure correct instrument mapping. These changes increased cross-version compatibility, reduced need for manual adjustments, and strengthened end-user value by expanding GP compatibility and accuracy for score conversion and playback. Business value: higher import fidelity, broader format support, fewer support tickets, and a more reliable conversion workflow for guitar/pro content. Key focus areas: tuning parsing accuracy, cross-version GP compatibility, and robust pitch/transposition handling.
