SIGMA's Sleep of the Shadow Featuring Buchla Inspired Electronic Music Box

You might remember the Buchla Inspired Electronic Music Box DIY-pages first posted here back in August of 2012. Sleep of the Shadow is a release featuring the system pictured below.

"Seed to this new Sigma-record came from my Electronic Music Box (EMB) project that was DIY-project for compact modular synthesizer. EMB has strong connection to Buchla’s Music Easel synthesizer and “Source of Uncertainty” (SOU) concept. Source of uncertainty is something that affects everything. SOU can occur at any point in music creation process, and it always varies from day to day. Because of this SOU is very strong tool in music and particularly in composition process where this random touch can lead to some interesting places. EMB has one implementation of SOU and can generate quantized random voltages. This means that you can choose from linear or geometric access to the number of random voltages. These voltages can be converted to musical pitches so that you can generate random sequences where randomnes is controlled by voltage. Examples of this technique can be heard on “Touch of Uncertainty”, “Strange Attractor” and “Decomposition”. “Electronic Druid” and “Orbital Maneuvers” where composed for “Ambient Laboratory” concert in 2011. “Sleep of the Shadow” and “Greener Grass” are harvest from “Greener Grass” art and documentary project by Mari Keski-Korsu.

Snip for the archives:
"Electronic Music Box (or just EMB) is my Buchla-inspired performance synthesizer. This project started when I wanted to give a new life to my old trusted Oakley VCO's. They are a kind of MOOGish design so here MOOG shakes hand with Buchla. Here below is a diagram of EMB's sound-generation arrangement. VCO1's triangle output is routed to Ian Fritz's Double Pulse Generator (DPG). DPG gives the usual PW and PWM but also Pulse Timbre and Pulse Timbre Modulation. VCO1 triangle and square outputs are routed to Bergfotron's Complex VCO Waveshaper that creates SIN, TRI, 2F SAW, EVEN and SPIKE waveforms. Oakley VCO's sine-output was not so perfect (these are older versions). It was more like filtered triangle-wave. Complex VCO Waveshaper gives a perfect sine-wave. Electric Druid's Noise Source generates white and pink noise. Noise outputs are also on frontpanel jacks so it is possible to modulate something with noise..."
