WeaveMuse: An Open Agentic System for Multimodal Music Understanding and Generation
Abstract
Agentic AI has been standardized in industry as a practical paradigm for coordinating specialized models and tools to solve complex multimodal tasks. In this work, we present WeaveMuse, a multi-agent system for music understanding, symbolic composition, and audio synthesis. Each specialist agent interprets user requests, derives machine-actionable requirements (modalities, formats, constraints), and validates its own outputs, while a manager agent selects and sequences tools, mediates user interaction, and maintains state across turns. The system is extendable and deployable either locally, using quantization and inference strategies to fit diverse hardware budgets, or via the HFApi to preserve free community access to open models. Beyond out-of-the-box use, the system emphasizes controllability and adaptation through constraint schemas, structured decoding, policy-based inference, and parameter-efficient adapters or distilled variants that tailor models to MIR tasks. A central design goal is to facilitate intermodal interaction across text, symbolic notation and visualization, and audio, enabling analysis-synthesis-render loops and addressing cross-format constraints. The framework aims to democratize, implement, and make accessible MIR tools by supporting interchangeable open-source models of various sizes, flexible memory management, and reproducible deployment paths.

Research summary
WeaveMuse presents a novel multi-agent system for music understanding and generation, emphasizing controllability and accessibility in MIR tasks. The paper's technical contributions are significant, but further empirical validation and methodological details are needed to fully realize its potential impact in the field.
Methodology
The methodology presented in WeaveMuse is innovative in its approach to creating a multi-agent system for music understanding and generation. The architecture effectively combines various specialized agents that handle different aspects of music processing, such as symbolic composition and audio synthesis. The use of a manager agent to orchestrate these interactions is a significant contribution, allowing for a seamless user experience across modalities. The emphasis on controllability through structured decoding and parameter-efficient adapters is commendable, as it addresses a critical need for flexibility in music information retrieval (MIR) tasks. However, the paper could benefit from a more detailed explanation of the specific algorithms employed within the agents and how they interact with one another.
Results & evaluation
The paper provides a conceptual framework and initial behaviors under constrained settings, but lacks extensive experimental validation. While it outlines the deployment modes and resource management strategies, concrete results demonstrating the performance of the system in real-world scenarios are limited. The authors mention using various models and tools, but without empirical data or comparative analysis, it is challenging to assess the effectiveness of WeaveMuse against existing systems. Future work should include rigorous experiments with quantitative metrics to substantiate the claims made.
Reproducibility
The authors have made efforts to ensure reproducibility by providing an open-source framework and a public repository. The identical planner and prompt templates for local and hosted configurations are a positive aspect for users looking to replicate the results. However, the paper could improve by including more detailed instructions on setting up the environment and running experiments, as well as providing sample datasets for testing.
Limitations
The paper acknowledges several limitations, such as the dependency on the underlying large language model's capabilities and potential performance degradation with smaller models. Additionally, the orchestration of tools and agentic prompting may not always yield the expected results, which could hinder user experience. The authors also note that the system is still a work in progress, indicating that further refinements are necessary.
Broader impact
WeaveMuse has the potential to significantly impact the field of music information retrieval and generation by democratizing access to advanced music processing tools. Its open-source nature and support for various models could foster community engagement and innovation. The framework's ability to facilitate intermodal interaction across text, symbolic notation, and audio could lead to new applications in music education, composition, and analysis. WeaveMuse presents a novel multi-agent system for music understanding and generation, emphasizing controllability and accessibility in MIR tasks. The paper's technical contributions are significant, but further empirical validation and methodological details are needed to fully realize its potential impact in the field.
