The Expanded Groove MIDI Dataset (E-GMD), a large dataset of human drum performances, with audio recordings annotated in MIDI. E-GMD contains 444 hours of audio from 43 drum kits and is an order of magnitude larger than similar datasets. It is also the first human-performed drum dataset with annotations of velocity. Additional information is available on the Magenta website: The Expanded Groove MIDI Dataset If you use the E-GMD dataset in your work, please cite the paper where it was introduced: Lee Callender, Curtis Hawthorne, and Jesse Engel.
