Conditional Generation

MAJEPPA generates expressive performances conditioned on a musical score and a target style. Each example below shows the same score realized under four different conditions — from virtuoso concert performance to novice practice.

🎹 Try it yourself: pick a score, choose a performer / recording condition, and generate live on our interactive demo. (First call after the Space wakes takes ~60–90s.)
