MuScriptor: Open-Source Multi-Instrument Transcription

kyutai · hf · 2026-07-15

MuScriptor is an open-weight model designed for **multi-instrument music transcription**, aiming to solve the issue where existing methods only work well on single instruments and generalize poorly to real-world, complex mixes. The authors' approach includes: - Pre-training on **synthetic data**, followed by fine-tuning with **real-world music audio**. - Conducting **reinforcement learning-style post-training** to enhance real-world applicability. - Introducing **instrument presence conditioning**, allowing transcription results to be customized by specific instruments. The paper/project claims that MuScriptor performs effectively on real-world recordings across various musical genres.
