Industrial Music Electronics

IME was founded in 2007 by Scott Jaeger (b. 1981, Redmond, WA, USA) and is the exclusive outlet for his music instrument design work. The IRON CURTAIN ELECTRONICS series is created in collaboration with Vladimir Kuzmin (b. 1953, Vladivostok, RSFSR), and consists of modular releases of his work on the famous Polivoks synthesizer and more.


IME instruments are suitable for realtime low art enforcement. They provide immediate access to a musically useful way of sonic control, and they directly react to physical displacement in the form of control voltages. They don’t use narrow, menu-driven user interfaces or organ keyboards, and the arrangement of the controls is memorable. Preference is given to extreme and corrupt sonic character, but the devices are naturally able to produce most sounds due to their modular, analog/digital hybrid design.


IME formerly operated as The Harvestman Digital Audio Electronics until 2015. Products are manufactured in Portland, Oregon at Darkplace Manufacturing.

Make Noise

Make Noise was founded in 2008 by Tony Rolando, a self-taught electronic musical instrument designer who got started by obsessively reading amateur radio books at the public library, building electronics for artists, such as the light controlled mixer for Simon Lee's "Bus Obscura," working for Moog Music, and playing in bands for many years. After 3 years of isolation on a mountain top he founded Make Noise.


What started as a re-visioning of jettisoned music technology has grown into a crew of folks working together in Asheville, NC, to design and build some pretty strange, but thoughtful modular synthesizers. We see our instruments as a collaboration with musicians who create once in a lifetime performances that push boundaries and play the notes between the notes to discover the unfound sounds. We want our instruments to be an experience, one that will require us to change our trajectories and thereby impact the way we understand and imagine sound. Also, we think what we do is fun and we hope you like it, too.
