Thanks for downloading Slakh2100! The Synthesized Lakh (Slakh) Dataset is a dataset for that is synthesized from the Lakh MIDI Dataset v0.1 using professional-grade sample-based virtual instruments. This release of Slakh, called Slakh2100, contains 2100 automatically mixed tracks and accompanying MIDI files synthesized using a professional-grade sampling engine. For more information, see www.slakh.com. *** IMPORTANT: Splits *** The original release of Slakh2100 was found to have many duplicate MIDI files. Some MIDI duplicates that are present in more than one of the train/test/validation splits. Even though each song is rendered with a random set of synthesizers, the same versions of the songs appear more than once. Same MIDI, different audio files. This can be an issue for some uses of Slakh2100, e.g., automatic transcription. The version of Slakh that you have downloaded contains a directory called `omitted`, where the tracks that have duplicated MIDI files have been moved. This version of Slakh is called Slakh2100-redux. For information about how to create other splits from your downloaded version, see https://github.com/ethman/slakh-utils/tree/master/splits *** CITING THIS WORK *** If you use this in a scientific publication, we ask that you cite the following: @inproceedings{manilow2019cutting, title={Cutting Music Source Separation Some {Slakh}: A Dataset to Study the Impact of Training Data Quality and Quantity}, author={Manilow, Ethan and Wichern, Gordon and Seetharaman, Prem and Le Roux, Jonathan}, booktitle={Proc.
