Giant Searchable Raw MIDI Dataset for Music AI

Monster MIDI Dataset is a large collection of raw MIDI files intended for music information retrieval and AI music generation. The dataset includes a stand-alone Python module for GPU/CPU-powered search and filtering. It is hosted by projectlosangeles and was last updated in November 2025.

Use Cases

• Train music generation models on raw MIDI note sequences and instrument data.
• Develop music classification systems using MIDI metadata and musical features extracted via the search module.
• Benchmark music information retrieval algorithms on a large corpus of symbolic music files.
• Filter and search for specific musical patterns or instrumentation using the provided GPU-accelerated Python module.

Strengths

• Described as a 'giant' dataset, implying a large scale of MIDI files.
• Includes a dedicated GPU/CPU search and filter tool for efficient data exploration.

Limitations

• Specific size, row count, and file format details are unknown.
• No information provided on data quality, licensing, or potential class imbalances.
