Yesterday’s Future: Don Buchla’s Legacy and The MEMS Project
September 19, 2026
The MEMS Project
The opening afternoon will feature two different lecture-demonstrations by the MEMS Project showcasing their work with two of Don Buchla’s most unusual modules. The first presentation will focus on the 276 EEG Conditioner, a module designed to hook up to electrodes attached to the user’s head that allow the user to control a synthesizer with their brainwaves. MEMS traveled to EMEAPP/MMT to study and reproduce Buchla’s original 276 prototype, which is part of our permanent collection. This first lecture will focus on the evolution of brainwave controllers and how Buchla was inspired to create one. This lecture will also feature a demonstration of the 276 module using volunteers from the audience.
The second presentation will focus on the slideshow controller module, which Buchla developed in the 1970s as part of the psychedelic house lighting equipment in NYC’s Electric Circus. The slideshow controller takes input from a synthesizer and uses it to control old-school slide projectors, allowing the musician to create an immersive audio-visual experience. MEMS will discuss how this module works and how and why Buchla created it. Slideshows created using the module will be demonstrated for the audience.
The Instrument That Started It All: Exploring the Buchla 100
September 19, 2026
Steve Horelick, The MEMS Project
The evening will feature a special presentation by The MEMS Project, highlighting their groundbreaking work restoring the legendary Buchla 100 synthesizer for the Library of Congress. This is the very instrument used by Morton Subotnick to create Silver Apples of the Moon, one of the most influential works in the history of electronic music. In the 1980s, the same Buchla system spent several years at the Aspen Music Festival and School, where composer Steve Horelick worked extensively with the instrument while studying and performing under the direction of Michael Czajkowski.
The MEMS Project will discuss the provenance and configuration changes of the system as it changed hands over the years and share highlights and stories from their experiences working deep within the Library of Congress vaults.
Steve—who later composed the Reading Rainbow theme—will reflect on his time working with the Buchla at Aspen and share how Michael Czajkowski’s original patching ideas continue to influence his approach today. His presentation will draw inspiration from those patching concepts, offering a personal, contemporary response to the instrument rather than a literal recreation.
We hope to have the original Subotnick Buchla 100 on site for demonstration (details are still being coordinated with the Library of Congress). If that is not possible, the presentation will feature The MEMS Project’s exceptionally accurate Buchla 100 reproduction system.
Afternoon at the Movies: SUBOTNICK: Portrait of an Electronic Pioneer
October 3, 2026
Join us in the afternoon for a screening of Waveshaper Media’s documentary film SUBOTNICK: Portrait of an Electronic Pioneer. This film explores the life of electronic music pioneer Morton Subotnick, who worked closely with Don Buchla at the San Francisco Tape Music Center to develop the first Buchla Modular Electronic Music System – the system Subotnick then used to create his landmark 1967 album Silver Apples of the Moon and many other subsequent works. At 90 years of age, Subotnick has become a cult figure for a whole new generation that have come to recognize him as “The Father of Techno.” Featuring live performances captured in surround sound and augmented with innovative liquid-light psychedelic effects, SUBOTNICK is a multimedia experience that highlights and celebrates one of the world’s most influential living composers. This movie makes a great lead-up to our evening lecture on Don Buchla’s place in the cybernetics moment. The exhibit will be open for viewing before and after the film screening.

Magic Wands and Morphing Mallets: A Day with Mark Goldstein featuring the Lightning Wands and Marimba Lumina
TBD
Mark Goldstein
Mark Goldstein began working and touring with Don Buchla in 1991, the year that Buchla’s Lightning Wands were introduced, and played a key role in the development of the Marimba Lumina, which first appeared in 2000.
Mark will lead a day-long experience focused on the development and use of the Lightning Wands and the Marimba Lumina. In two lecture/demonstrations Mark will discuss the genesis of each controller: how each one came to be and evolved over time.The first session will cover the Lightning and include a discussion of the iconic piece En Plein Vol (a.k.a. Thief) that Mark co-created and premiered with Buchla. Mark will discuss how his playing technique evolved as he started using Lightning to accompany silent movies live with organ and how this led to the idea of “gestural coherence,” a concept that has guided Mark’s exploration of electronic musical expression ever since. The second session will center on the Marimba Lumina. Mark will explain the history of the Lumina (originally called the Chromaphone) including how he envisioned and prototyped it, and then spent a year convincing Buchla to build it. Both sessions will include short performances by Mark demonstrating the capabilities of the instruments and attendees will be invited to come up and try playing them as well. A few volunteers from these sessions who are willing to stay and rehearse over the dinner break will be offered the opportunity to perform with Mark in the evening event.
The evening event will be an interactive workshop/performance featuring recreations of several historic pieces for Lightning that Mark and Don performed back in the 1990s, along with some of Mark’s own compositions for the Lightning and Marimba Lumina. Volunteers from the afternoon sessions will be featured in some of the pieces and additional participants will be selected on-the-spot from the evening audience. It will be a fun and relaxed event – and if you’ve ever dreamed of playing a Buchla instrument on stage in front of an audience, this is your once-in-a-lifetime chance!
