The Lakh Pianoroll Dataset (LPD) is a collection of 174,154 multitrack pianorolls derived from the Lakh MIDI Dataset (LMD).
We provide multiple subsets and versions of the dataset (see here). The dataset is available here.
The multitrack pianorolls in LPD are stored in a special format for efficient I/O and to save space. We recommend to load the data with Pypianoroll (The dataset is created using Pypianoroll v0.3.0.). See here to learn how the data is stored and how to load the data properly.
