[Elektronmusikstudion] (Swed.: ‘electronic music studio’)

The Swedish national centre for electronic music and sound art, in Stockholm. It was preceded by a smaller studio run by the Worker’s Society of Education from 1960. EMS was established by Swedish Radio in 1964 under music director and composer Karl Birger Blomdahl (1916–68), who hired the composer and performer Knut Wiggen (b 1927) to take charge of creating the studios. In 1965 an old radio theatre studio called the klangverstan (‘sound workshop’) opened for composers. Construction of a new facility was begun, but after Blomdahl’s death EMS became independent, funded only in small part by Swedish Radio, and otherwise by Fylkingen (a society for experimental music and arts) and the Swedish Royal Academy of Music.

Wiggen envisioned EMS as both a place to produce electro-acoustic music and a research institution that would give the composer ‘the possibility of describing sounds in psychological terms’. The studio was equipped accordingly. The sound sculpture ...

Unique MIDI synthesizer controlled by a gamma-ray spectrometer designed and built by Jerry Chamkis (b Los Angeles, CA, 1942). He studied physics at the University of California, Santa Barbara, but disillusioned by the emphasis on military applications, he left and became chief engineer at a radio station in Houston, Texas. In 1975, he formed AERCO (Acme Electric Robot Company), where he initially produced peripheral devices and memory expansions for small computers and then moved on to computer-controlled hot wire cutting systems, broadcast equipment, and microphone preamplifiers. Since about 2000 he has concentrated on various art projects such as the Kosmophone.

The gamma-ray spectrometer used for the Kosmophone operates at 3–7 million electron volts, the energy coming primarily from very high-energy cosmic radiation. Although mostly stopped by the atmosphere, gamma rays produce secondary energy emissions that the Kosmophone detects, sending the information to a synthesizer MIDI control port. The radiation pulses are processed and digitized to 12 bits, 7 of which are sent as the MIDI pitch value and 4 as the MIDI velocity value. The first Kosmophone was built from standard nuclear instrumentation modules and custom circuit boards. The second version is a self-contained portable unit with an integral detector, a self-contained nuclear analyser, an Alesis QSR synthesizer, and a 100-watt-per-channel amplifier. It was first shown publicly at the Electricity and Me show at Gallery Lombardi in Austin, Texas, in ...

Elizabeth Hinkle-Turner and Anne Beetem Acker

American firm specializing in digital audio workstations (DAW) featuring sound design applications and environments for music, film, advertising, television, audio research, computer games, and other virtual environments. Founded as Kymatics in 1989 by the musician and inventor Carla Scaletti and Kurt J. Hebel of the Computer-Based Education Research Laboratory (CERL) at the University of Illinois at Urbana-Champaign, the company was incorporated in 1990 as Symbolic Sound Corporation and is based in Champaign.

Scaletti, president of the firm and formerly a professional harpist, studied composition at the University of Illinois at Urbana-Champaign (DMA 1984); she also took the degree of Master of Computer Science at Illinois (1988) and the MM at Texas Tech University (1979). The Kyma system (see below) features almost exclusively in her later works, the interaction between performer, composer, and machine remaining a primary motivation. In 1995 Scaletti received an International Computer Music Association award for her interactive online installation ...
