Electronic Music Produced In Aarhus

Cover notes: The electronic music facilities in Aarhus consist of a first generation studio, a third generation digital system, and an advanced digital synthesizer, all of which are operated by the Department of Musical Acoustics, Institute of Musicology, University of Aarhus. There is also a recording studio with some first generation facilities at det Jydske Musikkonservatorium (the State Academy of Music in Aarhus) The first generation studios have been in use since about 1970, and many seminars and courses on electronic music have been held here. In addition, a large number of electronic compositions produced by danish composers, from which some of the more outstanding have been selected for this record. The equipment of the studios is the traditional kind: full and dual track 1/4/1, 7112/15 ips tape 1 decks, an 8 track 1/1 tape deck, mixing console, reverberation unit, filters, tone generators, pulse generators, noise generators, ring modulators, microphone equipment etc. The third generation system is a non real-time system running on a TI960A minicomputer system for A/D- and D/A-conversion and for remote access to the university's CDC 6400 system to do the actual processing. This system was constructed not only for producing electronic music but espeicially for performing research into musical acoustics. The digital synthesizer is a real time system consisting of a three manual touch sensitive keyboard, the TI960A system, a multi-channel digital sound generator unit, and an analogue amplifier and loudspeaker system. The synthesizer has been under development for two and a half years, and will be finished during the summer of 1975.
