HOYO-MiX
HOYO-MiX is a musical group and music studio under miHoYo, primarily responsible for producing songs and soundtracks for various miHoYo games, including the Honkai series, Tears of Themis, and Genshin Impact. The studio is headed by Cai Jinhan, miHoYo's music director.
It was founded after Cai Jinhan and his collaborators had their work using vocaloid songs acquired by miHoYo. Since officially forming in the early 2010s, the studio has produced soundtracks for miHoYo's games, releasing its first OST in 2014. While key figures like composer Chen Yupeng initially shaped the project's musical identity, HOYO-MiX evolved into a flexible team-based system even after Chen's departure. Beyond game music, the studio has collaborated with singers and orchestras worldwide such as the London Philharmonic and Tokyo Philharmonic Orchestra
Although HOYO-MiX consists of several groups of people working on different game projects, they are mostly credited as "HOYO-MiX" as a whole in their works on streaming platforms.
History
In an interview with Shanghai Morning Post, Cai Jinhan mentioned that the name "HOYO-MiX" is actually "miHoYo" spelled backward, and "MiX" refers to audio mixing. In "HOYO-MiX," only the letter "i" is lowercase, symbolizing the individual, as "we both respect the individual and serve the collective, which is because we are the music department of miHoYo, and serving the product is essential."In 2011, a Vocaloid music group called Hatsune Squadron, consisting of Cai Jinhan, Zheng Xiaoyu, and Xia Yihan, composed the theme song "Gradually Collapsing Hatsune Miku" for the manga Gradually Collapsing World. The copyright for this song was later acquired by miHoYo, thus the three joined miHoYo to establish the "HOYO-MiX" studio. Cai Jinhan took on the role of HOYO-MiX leader while also serving as the music director for miHoYo.
The first OST album released by HOYO-MiX was Honkai World Diva - Guns Girl Z OST on November 11, 2014. Since then, they have produced numerous albums and singles, including over 20 albums for Genshin Impact alone. These albums feature a variety of tracks, such as regional music, boss themes, battle themes, character trailers, and event-specific tracks.
The members of each game's music team, including the producer, are not unchanged. After the establishment of the Genshin Impact project, Cai Jinhan invited Chen Yupeng to produce the original soundtrack for Genshin Impact. In June 2020, Chen Yupeng officially joined HOYO-MiX as the music producer for Genshin Impact. In the early stages of music production for Genshin Impact, Chen Yupeng was primarily responsible. As the game's world expanded to include the Inazuma region, other music composers such as Yuan Dimeng joined the creative process. For the Sumeru region, music production involved Zhao Xin, Jiang Yijun, and other music composers. By the time of the Fontaine region, HOYO-MiX had established a comprehensive creative system and completed music production in the absence of Chen Yupeng's involvement. On September 12, 2023, Chen Yupeng announced his departure from miHoYo and the HOYO-MiX team to continue pursuing his musical dreams; the music producer role is succeeded by Yuan Dimeng, who also came from Chen's studio.
On December 12, 2021, miHoYo's HOYO-MiX and the Shanghai Conservatory of Music jointly hosted the 2021 Shanghai Conservatory of Music International Digital Music Festival. The event included activities such as a summit forum on game music creation and the finals of a game music competition, leading to the establishment of the "Digital Music Professional Alliance." Professor An Dong from the Shanghai Conservatory of Music, the artistic director of the Shanghai Conservatory of Music International Digital Music Festival, and a well-known composer, served as the director of the alliance. Cai Jinhan, the music director of miHoYo, served as the deputy director and deputy secretary-general. In March 2023, HOYO-MiX continued to host the second Shanghai Conservatory of Music International Digital Music Festival, upgrading the "Digital Music Professional Alliance" to the "Digital Music Audio Professional Committee."

Musical style and influences
Musical style
Former music producer of HOYO-MiX's Genshin Impact soundtrack, Chen Yupeng, expressed in an interview that the aim of the music is to touch the players and fully immerse them in the game world. "The music needs to have beautiful melodies, and it always sounds full of hope and passion. It brings out the poetic, beautiful and humanistic feelings within the listeners." The music producer of HOYO-MiX's Honkai: Star Rail soundtrack, Gong Qi, mentioned that the creation team places great emphasis on the combination of music and storyline. The purpose of the soundtrack's production is to enhance the narrative experience, making the gameplay more immersive, "like doing music design for an animated film." Manager of HOYO-MiX, Cai Jinhan, stated that each player's encounters and emotions during their journey are unique. "Making the music and the storyline complement each other, and accompany Trailblazers with just enough presence to witness this adventure into the stars, is our top priority in composition." In terms of character music, Cai Jinhan remarked that music is a new interpretation of characters, a process of re-creation, "to put it most simply, it is about 'purpose' and 'function.'" Additionally, to avoid auditory fatigue for players, the rhythm of most outdoor exploration music is very soothing and peaceful, and the duration is relatively short.Genshin Impact chooses traditional orchestral music as its base, incorporating elements of world music on top of this foundation, and the music also adopts regional and cultural influences according to different areas in the game. Honkai: Star Rail selects a small orchestral ensemble to highlight the intricacy of melodies and the details in performance, while appropriately integrating electronic synthesizers and electronic percussion elements.
