Participants in the meeting, amongst others, were Werner Meyer-Eppler, Robert Beyer (de), Fritz Enkel and Herbert Eimert (Morawska-Büngeler 1988, 3, 7). Robert Beyer had been speaking of timbre-oriented music since as early as the 1920s. He thought the time was ripe to bring this idea to fruition. Fritz Enkel was the technician who conceptualized the first establishment of the studio. Herbert Eimert was a composer, musicologist, and journalist. In the 1920s he had published a book on the theory of atonal music, which had gotten him expelled from Franz Bölsche (de)'s composition class at the Cologne Musikhochschule (Anon. n.d.). Ever since his youth, he had stood on the side of radical musical progress and organized concerts with noise instruments.

At the end of the above-mentioned report the availability of the men Trautwein (Düsseldorf) and Meyer-Eppler (Bonn) was pointed out. Cologne lies between Düsseldorf and Bonn. In the early 1930s Friedrich Trautwein (de) had developed the Trautonium, one of the earliest electronic musical instruments. A version of the Trautonium, called the Monochord, was created for the studio. Meyer-Eppler carried out his experiments in Bonn with a Melochord. Harald Bode had constructed this instrument and modified it according to Meyer-Eppler's wishes. A Melochord was therefore also purchased for the Cologne studio. The Monochord and, especially, the Melochord can be understood as precursors to or an early form of the synthesizer. Synthesizers played an important role in the subsequent history of the studio.
