-In this stage, we will manually pick 3 songs for evaluation. First, we will use [https://pypi.org/project/osu-sr-calculator/ osu! star rating calculator] to calculate the star ratings of the generated beatmaps. This allows us to assess whether the model's difficulty conditioning is functioning correctly. Then, we will follow [https://osu.ppy.sh/wiki/en/Client/Beatmap_editor/AiMod AiMod] and [https://github.com/Naxesss/MapsetVerifier MapsetVerifier] to detect unplayable placements of objects algorithmically. Models passing this evaluation phase will move on to human evaluation.

-Rhythm game is a genre of video games that require players to '''physically react in sync with music'''. A rhythm game chart consists of '''a sequence of timed note events synchronized with an audio track''', defining what actions players should perform and when players should perform these actions during gameplay. Rhythm game charting is a difficult and time-consuming task that requires musical expertise, and it is a common case where players want to play a song that does not have an existing chart. While increasing number of work has been done on automatic rhythm game chart generation in recent years, generating '''high-quality''' rhythm game charts that people enjoy playing remains a challenge.

 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.

-In this stage, a single showcase song will be selected for community evaluation. Participants will choose a difficulty level aligned with their skill level and playtest charts generated by each model alongside a human-authored chart. Players will vote on musical representation, creativity, gameplay, and they will be asked to identify which chart is authored by human.

 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).
