Kosuke Saito (born December 17th, 1983) is a commissioned artist for BEMANI who made his debut in beatmania IIDX 4th style, winning a Musicianship Trial to be in beatmania IIDX. (Ryu☆ won this same contest.) Kosuke returned in beatmania IIDX 9th style by request of dj TAKA, and has been a regular contributor to beatmania IIDX since, being one of the only commissioned artists (alongside Ryu☆) considered part of the "core" beatmania IIDX sound team.
Kosuke is, by far, one of the most variated music artists inside BEMANI. While his earlier style was more trance and hardcore based under his teranoid alias, he also composes a lot of reggae and R&B. With the years passing he's also done a lot of happy hardcore/makina under the CANDY RAVE series which started with SigSig, as well as some notorious psy-trance songs under his Programmed series.
Lately, his style incorporates elements of EDM, happy hardcore, trap, and future bass, positioning him as one of the big names in Japanese dance music, inside and outside of BEMANI. Also, under his Eagle alias, he does drum'n bass, drumstep, glitch hop and wobble bass based genres, including a handful of songs for beatmania IIDX.
As of 2017, Kosuke is now a producer for EXIT TUNES Dance Production. With the decision to take on the responsibility of a commercial label, he also announced later that S2TB Recording would be put on hold for an indefinite period of time at the end of the year.
- Outside of BEMANI, Kosuke Saito has also composed songs for Pentavision's DJMAX series, under the alias Oriental ST8.
- As of 2018, he is in charge of the BGM for グラフィティスマッシュ (Graffiti Smash), a game by BANDAI NAMCO.
- Kosuke has admitted to being a big fan of the cartoon show The Simpsons. He did a remix of the opening theme once for MC NATSACK's radio show, and ay carumba!!!! was named specifically after character Bart Simpson's catchphrase.
- Poochie is also named after a Simpsons character.
