 In osu!, a beatmapset is a '''packed archive''' with <code>.osz</code> extension that contains a '''song''' in <code>MP3</code> or <code>Ogg</code> format, a set of '''game levels (difficulties)''', and other audio and visual materials. Each game level is stored in a '''text file''' with <code>.osu</code> extension, which includes 7 sections: General, Editor, Metadata, Difficulty, Events, Timing Points, and Hit Objects. This year, we specify the task as predicting '''hit objects (mandatory)''' and '''inherited timing points (optional)''' based on the '''audio''', '''difficulty level''', and '''ground truth uninherited timing points'''. While existing research mostly focuses on hit objects, inherited timing points are also critical factors to carry musical meanings and make a chart feel human-like. Consequently, we include the generation of inherited timing points as an optional task to encourage participants to push the boundaries of current research. To ensure consistency, we restrict the difficulty levels to be Kantan, Futsuu, Muzukashii, Oni, and Inner Oni (Ura Oni).

 To define the task within the scope of MIREX challenge, we specifically choose the task of generating '''osu!taiko''' beatmaps this year. osu!taiko is a game mode in osu! inspired by Taiko no Tatsujin, which features a horizontal conveyor belt of drum notes moving towards a judgment circle. In this game mode, players typically use a keyboard to strike different types of notes with precise timing. A high-quality mapping in osu!taiko involves many different aspects of music, including rhythmic perception, musical structure awareness, pitch awareness, musical instrument awareness, and so on.
