[1][2] Wiggen was head of the Fylkingen in Sweden (1959–69)[3] and director of EMS - Elektronmusikstudion [sv] (1964-75).
Wiggen started trying to create new connections between art, music and technology, including in collaboration with Moderna Museet, where Pontus Hultén just had become leader.
[citation needed] In 1963 he started a small electroacoustic studio in ABF's premises in Stockholm[4] where among others Gottfried Michael Koenig, György Ligeti and Iannis Xenakis came to hold courses in composition, where for example Lars-Gunnar Bodin and Bengt Emil Johnson attended.
Along with the American David Fahrland, Wiggen created the audio control program MUSICBOX which is used in the composition of electronic music.
Due to the conflict, Wiggen left EMS in 1975 and moved back to Norway, where he removed all the documentation of MUSICBOX.
