Taiko no Tatsujin Sorairo Version Arcade Machine is from the music and rhythm series and the second major update to happen to the 2011 Taiko rebrand release.
All the songs and gameplay features that were gradually added are carried forward to this upgrade, including DonChare, the Dojo Ranking mode and all the song folder options. The name 'Sorairo' is added to the official title logo instead of being a mere codename like Katsu-Don, and the interface gets a fresh blue color in contrast to the warm tones used in the previous firmwares.
Not many new features are introduced in this installment, however the biggest shuffle in the songlist is the relocation of all Vocaloid songs in all genres to their own designated Vocaloid genre, a move which promotes even more proliferation of the voice synthesizers in Taiko. All online player data is also moved from 0.5 to Sorairo.
There are a total of 19 secret songs, 50 Ura (1 pl) songs, and 35 songs added through updates post release with a grand total of 318 playable songs. Song genres include J-Pop, Anime, Children/Folk, Vocaloid, Classic, Gam Music, and Namco Originals
