Siemens Synthesizer

Among others, Mauricio Kagel, Henri Pousseur, Herbert Brün and Ernst Krenek completed important electronic works there.

[1] In 1955, Siemens established an audio laboratory, the Siemens Studio für Elektronische Musik, in its Munich facilities to produce electronic music for its publicity films.

Siemens engineers Helmut Klein and Alexander Schaaf were charged with assembling the components for the studio and providing a means for controlling the composition, synthesis, and recording of music.

Equipment found in the studio included a bank of 20 oscillators, a white noise generator, a Hohnerola (a hybrid electronically amplified reed instrument marketed by Hohner) and an impulse generator.

[5] The Siemens Synthesizer offered a method for controlling its tone-generating facilities, modification and modulation of the sounds in real time, and the manipulation of recorded material into finished works.
