Buchla Touché (Late 1970s)

An early digital synthesizer developed with musician David Rosenboom. It is known for its sound generation and for its use on the Shasta Cults LP.

Overview

The Buchla Touché is an early digital synthesizer. Don Buchla and experimental musician David Rosenboom built it in the late 1970s. It came out of Buchla's interest in digital oscillators and non-traditional control methods. It was tailored for pianist-composers, even though Buchla was skeptical of the conventional keyboard. The idea was to explore new timbral possibilities with advanced algorithmic synthesis techniques.

Design

The Touché makes its timbres with non-linear waveshaping algorithms, which is a different approach from standard additive synthesis. David Rosenboom programmed it in FOIL (Far Out Instrument Language), a custom software language he developed for the instrument. Buchla wanted to advance digital oscillator design, and the finished system favored expressive, evolving sounds under 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 on Richard Smith's self-titled album under the name Shasta Cults.

Market

The Touché can be cranky in operation and is prone to freezing during use. The user manuals gave limited guidance on the FOIL programming language, so mastering it took extensive trial and error, logical deduction, and hands-on troubleshooting. Richard Smith is a recognized Buchla technician who learned repair through apprenticeship. He is a primary resource for maintaining and restoring these instruments.
