Groove2Groove MIDI Dataset: synthetic accompaniments in 3k styles

The <em>Groove2Groove MIDI Dataset</em> is a parallel corpus of synthetic MIDI accompaniments in almost 3000 different styles, created as described in the paper <em>Groove2Groove: One-Shot Accompaniment Style Transfer with Supervision from Synthetic Data</em> [pdf]. See the <code>README.md</code> file or the <em>Groove2Groove website</em> for more information. The dataset is split into the following sections: <code>train</code> contains 5744 MIDI files in 2872 styles (exactly 2 files per style). Each file contains 252 measures following a 2 measure count-in. <code>val</code> and <code>test</code> each contain 1200 files in 40 styles (exactly 30 files per style, 16 bars per file after the count-in). The sets of styles are disjoint from each other and from those in <code>train</code>. <code>itest</code> is generated from the same chord charts as <code>test</code>, but in 40 styles from the training set. Chord charts for all MIDI files are provided in the ABC format and the Band-in-a-Box (MGU) format. Each chord chart corresponds to at least 2 MIDI files in different styles. The code used to automate Band-in-a-Box is available in the pybiab package.
