Buchla Touché (Late 1970s)
An early digital synthesizer developed with musician David Rosenboom, known for its unique sound generation and use on the Shasta Cults LP.
Overview
The Buchla Touché is an early digital synthesizer created in the late 1970s through a collaboration between Don Buchla and experimental musician David Rosenboom. Designed as a response to Buchla's interest in digital oscillators and non-traditional control methods, it was tailored for use by pianist-composers despite Buchla’s skepticism of the conventional keyboard. The instrument was built to explore new timbral possibilities using advanced algorithmic synthesis techniques.
Design
The Touché is an early digital instrument that uses non-linear waveshaping algorithms for timbre generation, differing from standard additive synthesis approaches. It was programmed by David Rosenboom using FOIL (Far Out Instrument Language), a custom software language he developed specifically for the instrument. Buchla’s goal during its creation included advancing digital oscillator design, and the resulting system emphasized expressive, evolving sounds through algorithmic control.
Context
Don Buchla collaborated with David Rosenboom, a pianist and academic, to develop the Touché—bridging Buchla’s aversion to traditional keyboards with the needs of classically trained performers. Rosenboom performed and recorded extensively with the instrument, integrating it into hundreds of live shows and studio works. The Touché stands as a unique artifact of experimental music research from the late 1970s, reflecting both technical innovation and artistic collaboration.
Reception & Use
The Touché has been described as sounding "gorgeous," with rich and complex tonal characteristics. It was the sole instrument used on Richard Smith’s self-titled album under the name Shasta Cults, highlighting its capability as a complete compositional tool. Its distinctive sonic footprint and extensive use in performances and recordings make it a notable piece in the history of electronic music.
Market
The Touché can be cranky in operation and is prone to freezing during use. User manuals provided limited guidance on the FOIL programming language, requiring extensive trial and error, logical deduction, and hands-on troubleshooting to master. Richard Smith, a recognized Buchla technician who learned repair through apprenticeship, is a primary resource for maintaining and restoring these instruments.
