🎵 Lakh MIDI to MMM-Style Text Dataset

This dataset converts the Lakh MIDI Dataset into a structured text format inspired by the Multitrack Music Machine (MMM) paper. It includes 344,900 samples, each representing an 8-bar symbolic music fragment, tokenized into a language-model-friendly format.

Each line in the dataset is a music fragment composed of tokens like:

PIECE_START COMPOSER=JOHN_FARNHAM PERIOD= GENRE=TIME_SIG=4/4 TRACK_START INST=122 DENSITY=0 BAR_START TIME_DELTA=48 BAR_END ...

🔍 Metadata

• Modality: Text (converted from MIDI)
• Format: One tokenized sequence per line (plain text)
• Size: 344,900 rows
• Source: Derived from the Lakh MIDI Dataset
• Structure: Each row represents an 8-bar segment tokenized to match MMM syntax

🤖 Use Cases

• Pretraining or finetuning symbolic music models
• Sequence modeling research for music
• Input for generative transformer models
• Creative AI applications in music composition

🧠 Why this dataset?

Symbolic music datasets in tokenized, language-model-ready formats are rare. This dataset bridges audio-derived symbolic data and the world of NLP modeling, saving hours of preprocessing and formatting work for researchers and ML developers.
