MusGU+: Musician-Centered Evaluation Framework

The Music-Generative Usable+ AI (MusGU+) framework is a musician-centered evaluation framework designed to assess how generative music models can be adapted, used, and controlled in real-world creative contexts. The framework evaluates models along three complementary dimensions, with each dimension addressing a key question from the musician's perspective:

This website accompanies the paper MusGU+: Toward a Musician-Centered Evaluation Framework and Discovery Tool for Generative Music AI, authored by Laura Ibáñez-Martínez, Roser Batlle-Roca, Xavier Serra, and Martín Rocamora, and accepted for presentation at the 7th Conference on AI Music Creativity (AIMC 2026). It is a living resource that continues to expand through community contributions.

How to navigate this table?

The MusGU+ framework evaluates models across 15 criteria distributed among three dimensions: Adaptability (5 criteria), Usability (6 criteria), and Controllability (4 criteria). Each criterion is evaluated on a three-level scale: ✔︎ fully supported, ~ partially supported, or ✘ not supported.

The table includes interactive elements:

Relationship to MusGO

MusGU+ builds on the MusGO framework (Music-Generative Open AI), adopting its composite and graded evaluation approach while shifting the emphasis from openness toward practical suitability for musicians. While MusGO focuses on openness and responsible research practices, MusGU+ focuses on whether generative music systems can be adapted, used, and controlled in real-world creative contexts. The two frameworks provide complementary perspectives on generative music AI.
