Buchla 200 Modular Synth

The Buchla Electric Music Box, Series 200, is a comprehensive collection of electronic modules for generating and processing sound. The Buchla 200 is a system designed for those who desire simultaneous control of many aspects of sound.

The system features high functional density, extended dynamic range, self-contained monitoring (preview) facilities, and expandability. Interesting new techniques for polyphonic signal generation, dynamic spectral and timbral modification, complex pattern generation, and control of spatial location and movement are also characteristic of the Buchla 200 modular synthesizer.

Connections within the system are made with color-coded patchcords. A clear and consistent distinction is maintained, both in modular function and in interconnection, between signals (the raw material of electronic music), control voltages (defining parametric structure, e.g. pitch, timbre, intensity, location), and timing pulses (defining event times and durations).

Components of the Electric Music Box are designed to interface readily with digital computers. All musical parameters are voltage (and therefore computer) controllable.

The Electric Music Box can be configured to serve a variety of applications, including electronic music composition and performance, music education, psychoacoustic studies, environmental control, special effects generation, bio-feedback research, and video synthesis.
