follow-up to the One Knob to Rule Them All post. "The LCO is an instrument I assembled when I was creating the score for "The Conduit". I used it as a starting point to create a variety of bass sounds, ambiences and strange noises.
The pitch of an optical theremin responds to the intensity of external light, which makes playing specific notes difficult. I wanted to find a better way to control not just the pitch but also the trigger of the sound in order to create rhythmic patterns. I used the chassis of an old device to host the circuit, connected a dimmer to control the intensity of a light bulb and a push-button switch to break the circuit, so I could control the note on/off. To fatten up the sound I connected it to a spring reverb, an hi-fi amp and two old speakers, recorded with a stereo microphone. The instrument needs to be be played in semi obscurity.
In this particular session I was also post-processing the sound of the LCO with modulated chains of comb-filtered delays and reverbs.
P.S. Careful with the volume, the sound gets pretty intense in the second half of the video."
YouTube via bigcitymusic "Made by Malekko and designed by Wiard, the Boogie is a great sounding filter module. A resonant low pass, the Boogie has two audio ins, two cv inputs(one key in and one with attenuator). and outputs for 6dB, 12dB, 18dB and 24dB. There are two user-friendly jumpers on the back of the module that control the phase of the 12 and 24dB outputs. The Boogie ships with the jumpers in the out of phase position. If you mix all the outputs together you can get some great variations happening. We're using the Analogue Systems rs165 Signal Mixer, the Cwejman VCO-2RM saw wave and the Analogue Solutions Vostok sequencer."
