A 25 Oct 2026 arXiv paper trains 26 language models on MusicXML, MIDI and ABC and reports that the MusicXML models do better at both understanding and generating music. For producers who work in MIDI, here is what that means and what it doesn't.

A piano roll is the grid in a DAW where you write and edit MIDI notes: pitch runs bottom to top, time runs left to right, and each note is a bar you can draw, move, stretch or delete. It means you can write music without playing an instrument. AI now writes into the same grid, so a part an AI composes is notes you can still edit by hand.

A new arXiv paper from Jakub Poćwiardowski and Mateusz Modrzejewski looks inside two text-to-MIDI models, finds internal features linked to musical traits, and tests whether nudging them changes the MIDI that comes out. One synth-lead feature held up; most effects were small.
