Quality Labeled MIDI Music Loops

MIDI Loops is a collection of quality-labeled MIDI music loops, each precisely 32 beats or 8 bars long. The dataset was compiled by asigalov61 from the LAKH MIDI dataset and the Annotated MIDI dataset, with loops numbered in order of composition. It was last updated in November 2025.

Use Cases

• Train sequence models to generate 8-bar MIDI loops using the 32-beat structure as a target output.
• Develop classifiers for musical style or genre using the quality labels associated with each loop.
• Build music continuation models by leveraging the ordered composition numbering of loops.
• Create music similarity search systems using the structured, non-overlapping loop data.

Strengths

• All loops have a consistent, uniform length of 32 beats or 8 bars, simplifying model input design.
• Loops are quality-labeled and sourced from two established MIDI datasets (LAKH and Annotated MIDI).

Limitations

• The exact number of loops, rows, and total dataset size is unknown, making it difficult to assess scale.
• The specific license terms are unclear, only indicated by a platform tag.
