Coupland Synthesizer & Clara Rockmore's Theremin at the Musical Instrument Museum in Arizona



Some pics in via Greg of Le Shat Noir and The Cripples [they are playing Slim's Last Chance in Seattle this Friday!], from a recent visit to the Musical Instrument Museum in Arizona.

These are the first pics of the Coupland in the flesh to be featured on the site. Previously, the Coupland has only be featured in various brochures. Be sure to see them for additional info.

From the MIM website:

"At MIM, you can see several synthesizers, including the Coupland Digital Synthesizer, which was invented by Rick Coupland in Phoenix in the 1970s. Coupland grew up playing the piano and dreamed of a keyboard instrument that could play any sound he imagined. In the early 1970s, he developed one of the first fully digital synthesizers. It offered touch-sensitive controls that could modify dozens of parameters of sound, in real time, while the player was playing. Though the Coupland Digital Synthesizer never went into production, many of its fundamental technologies and concepts later became standard features of popular, affordable synths from major manufacturers. The original prototype, now on display at MIM’s Electronic Music exhibit in the United States / Canada Gallery, was a fascinating prediction of music’s digital future."

You can find an image of Clara Rockmore's theremin from the museum further below, however there's no additional info on it on their website.

There was also an Indonesian Yamaha PSR-A1000, pictured below, for those interested! :)

P.S. Click on the panel pics to zoom in for the parameters. Note the Harmonic Number section with Phase Angle and FOURIER button.

Touché: Don Buchla’s Rare Polyphonic Keyboard Instrument


video upload by Sarah Belle Reid

Follow-up to Sarah Belle Reid plays the Buchla Touché

"In this video, I explore an extremely rare electronic instrument called the Touché, created by Buchla and Associates in 1980. Filmed at the Buchla Archives in Vancouver, this is a rare opportunity to hear and see an instrument that very few people have ever encountered firsthand. Only around five Touchés are known to have been built, and very few remain functional today. Because of this, the instrument has remained largely absent from public performance and documentation. This video helps bridge that gap by sharing the Touché’s sound, design, and historical context.

While Don Buchla is best known for his modular synthesizers such as the 100 and 200 Series, he also created a number of non-modular, computer-based instruments that explored new relationships between performance, software, and sound. The Touché is one such instrument. Conceived by Don Buchla in collaboration with composer David Rosenboom, it is a bi-timbral, eight-voice polyphonic keyboard instrument that combines digital sound generation, analog processing, and computer-mediated control.

The video begins with a historical overview of how the Touché grew out of Buchla’s computer-controlled instruments of the 1970s, including the 300 Series systems. From there, the video moves into a detailed walkthrough of Touché’s sound architecture, including many musical demos.
This video was created in collaboration with the Buchla Archives, an organization dedicated to the thorough and thoughtful documentation and preservation of Donald Buchla’s work.

Special thank you to Ryan Gaston and David Rosenboom for research assistance."

Nova Wind (1983)

video upload by David Rosenboom

"This video, shot informally in the Ensemble Room at Mills College in 1983, contains the only footage known of David Rosenboom playing his 1981 composition Nova Wind from Future Travel. In it, he plays the legendary Touché—digital/analog keyboard instrument produced in collaboration with Donald Buchla in 1979-1980—, violin, piano, and ancillary electronics. A complete studio recording of Future Travel was released first on a vinyl LP by Street Records in 1981 and later on a double-CD from New World Records in 2007."
