Born in Turku, Finland, Jonne Valtonen has been involved in several different music projects including for the PC demoscene, video games, theater plays, films, concerts, bands, and a solo album.

His first formal musical training was learning to play the classical piano at age nine. For several years, he appeared to continue his formation autodidactically. However, during his late 20's and early 30's, Valtonen studied classical composition at the Pirkanmaa Polytechic and Sibelius Academy in Finland. The primary instrument he studied is the piano and he took the harp as his second choice.

Like many European composers, Valtonen was introduced to the world of computer and video game music through the Commodore 64. After experimenting on this system, he became involved in the PC demoscene for a period between 1991 and 1996. Under the alias "Purple Motion", he was part of the popular Finnish group Future Crew as one of the two musicians (the other one was Skaven (Peter Hajba)). The group won several awards at events such as Assembly and The Party. Valtonen's most popular demoscene compositions include "UnreaL II (Second Reality)", "Satellite One", and "Starshine".

Death Rally was the first game he worked on, developed by Remedy Entertainment (a company formed by ex-members of Future Crew) and released on PC. The soundtrack was highly influenced by his demoscene experience, the principal relation being the tracker format. He worked on many other games, having notably scored several titles on portable systems (Game Boy Color/Advance, Symbian, Zodiac, Windows Mobile) for companies such as Paragon 5, Ninai Games, Fathammer, and Housemarque, plus a number of low budget PC games by PopCap Games.

Valtonen co-founded Valtone Oy in 1998, a company dedicated to music production for the entertainment industry. Contracts have been made in the video game industry, but also for theater and film projects, including House by the Sea for which he won the Best Soundtrack Award at the International Fest of Cinema & Technology.

He was a participant on the two Merregnon Soundtrack volumes, which are fantasy concept albums collectively composed by VGM artists. Valtonen also appeared on Number Nine, a Chris Hülsbeck album, as arranger of the Turrican 3 Piano Suite. Since the beginning of 2008, he has also been music director of Merregnon Studios.

In 2004, he released Musicdisk under his Purple Motion handle, an album featuring mostly electronic music. It was created in the spirit of the old demoscene days, actually featuring three remakes from his Future Crew repertoire.

Valtonen's classical background has granted him the ability to work as arranger and orchestrator for video game concerts since 2005. Projects he worked on so far include the Leipzig Symphonic Game Music Concerts, PLAY! A Video Game Symphony, and Symphonic Shades - Hülsbeck in Concert. He contributed a few arrangements for each of them, touching to series such as Super Mario Bros., The Elder Scrolls, Metal Gear Solid, The Legend of Zelda, and Castlevania. However, the Symphonic Shades concert will see him as main arranger for almost all music, with Yuzo Koshiro and Takenobu Mitsuyoshi contributing one piece each.

• The "Purple" from his demoscene handle (Purple Motion) comes from the rock band Deep Purple.
• He played keyboards for Finnish bands Decoryah and House of Mirrors.
• Timo Haanpää is a close collaborator, doing production and mixing work and playing guitar in many of Valtonen's projects.
