Roland_Kuit_Buchla_200_EMS_Stockholm_7On February 25, composer/synthesis-researcher Roland Kuit will be broadcasting live and in stereo from EMS in Stockholm for the Dutch Concertzender Radio, demonstrating his work with Kyma and the Buchla 200 interacting with each other in EMS Studio 4.

At the heart of these compositions are the Kyma algorithms that Kuit uses to frequency-modulate the Buchla Complex Waveform Generator Model 259 which, in turn, is used as trigger function for the Sequential Voltage Source Model 243, thus exploring the intriguing area that lies between note triggers and wavetables. This sequential control voltage is controlling a second Complex Waveform Generator Model 259. And the audio of this Waveform Generator is used as the carrier for the 285e Frequency Shifter / Balanced Modulator. The 266e Source of Uncertainty modulates a third Complex Waveform Generator Model 259 and is used as modulation signal for the Balanced Modulator which is fed through 296e Spectral Processor for filtering. Finally the loop is closed by routing these algorithmic audio ‘sentences’ back to Kyma for Ring Modulation and quadraphonic placement.

Kuit is a frequent guest on the Concertzender where he’s often called in as a modular synthesis expert to explain various synthesis algorithms or to discuss music by some of the pioneers of electronic music.

EMS#1 will stream live on 25 February after which it will be available as a podcast from the Concertzender archive.
