Ken Stone/1973 classic Serge

Ken Stone's observations of his 1973 classic Serge led him to conclude that there were not as many module designs to choose from at this time as there were later, as there is significant repetition on this unit, and some "standard" modules are conspicuous by their absence.[1]


This Serge synthesizer was assembled by Warren Burt, originally for the Center for Music Experiment (CME) at the University of California, San Diego, and was imported into Australia to be used at the Clifton Hill Community Music Centre. It was later acquired by Rainer Linz, and used in a number of performances of Stelarc.[1]

As is typical of these early Serges, this one is "cased" in a simple wooden frame. In fact, when he first received it, the panels were held into the frames by washers clamped under screws, at least one panel was no longer secure. A feature of this synthesizer that separates it from most Serge synthesizers is that it is equipped with 3.5 mm jacks instead of banana jacks. The 3.5 mm jacks were used because Roger Reynolds at CME felt that banana plugs would be too flimsy and prone to bad connections. By the time Ken received this instrument, barely any of the 3.5 mm jacks were still operational due to bending of their contacts, and corrosion build-up. Being open-frame jacks, they were repairable.[1]
