I am thrilled to share that MidiCaps - A Large-scale Dataset of Caption-annotated MIDI Files, has been accepted at ISMIR Conference. The MidiCaps dataset is a large-scale dataset of 168,385 midi music files with descriptive text captions, and a set of extracted musical features. The captions have been produced through a captioning pipeline incorporating MIR feature extraction and LLM Claude 3 to caption the data from extracted features with an in-context learning task. The framework used to extract the captions is available open source on github.
