Aleksi Eeben

During this period, he returned to composing music for the Commodore 64 and developed tracker software for the computer named John Player, feeling that other music tools for the system were unintuitive. He also developed Polly Tracker in 2004, a 4 channel MOD tracker for the Commodore 64 and Sid Vicious in 2006, a software emulator of the Commodore 64's SID chip for the VIC-20. He has also returned to developing Game Boy software, including the monophonic synthesizer Carina in 2022; funding was supported by Arts Promotion Centre Finland.

Following his work as a freelance game composer, Eeben joined Nokia as a principal sound designer in 2002, although continued to work on demoscene and chiptune-related projects in his own time. During his time at the company he composed ringtones, alerts and other sounds, as well as being responsible for creating DLS sound banks for phones and managing projects. He later served as the creative director of ringtone sets on Lumia models, which included a selection of ringtones performed by the Bratislava Symphony Orchestra and conducted by David Hernando Rico. The team collaborated with Asbjoern Andersen of the music company Epic Sound, who was another former demoscene musician. He also developed a Windows Phone app in 2014 named Nokia Tones, which includes 1000 Nokia ringtones. The team also worked with a jazz band to create ringtones.

In 2001, he composed for the Game Boy Color game Project S-11, with fellow demoscene musician Jonne Valtonen. Paul Bragiel, the founder of Paragon 5 which developed this game, recruited both composers to write music using the company's own tracker, Game Boy Tracker. The music in this game has been considered by critics to be rather complex for the system. Additional titles he composed for include Tom and Jerry: Mouse Hunt and an unreleased game, as well as a track for the homebrew game Mean Mr. Mustard and the Game Boy Advance game Hardcore Pinball. He also developed a music tracker for the Game Boy Color titled Carillon Editor, as well as demos for the system.

Eeben has also released a large number of solo albums and EPs, as well as participating in collaborative albums by CNCD. The first EP he released was Please Annihilate Oulu in 2000, through the net label Monotonik. The label later released Music Box and The White Box in 2002 and 2004 respectively, two collections of SID modules he composed. He later released non-chiptune albums through the label, and has also released albums through the Kahvi net label. His albums are currently self-published on his Bandcamp.

Eeben joined the demoscene group Rebels in 1990, and later formed his own group Carillon, which merged with Cyberiad to form the group CNCD. He composed hundreds of tracks for demos and competitions, as well as the soundtrack for the Amiga game Elfmania. He later became inactive in the demoscene, although continued to compose music, while his younger brother continued being active composing music in the demoscene.
