Lumanoise V4 is a compact drone synthesizer based on four Trautonium-style sub oscillators plus filter. Photocells are used for controlling the instrument.
Lumanoise V4 is a drone synthesizer inspired by the Oskar Sala Trautonium synth oscillator section. It features one master oscillator and four sub-oscillators.
Each sub-oscillator provides an individual volume potentiometer as well as a frequency knob to adjust the division factor.
The T. Master photoresistance allows to control the pitch of the master oscillator. Addtionally there is a switch which allows to select the pitch range (High, Med, Low). Furthermore a mini jack input allows to connect an external LDR, a potentiometer or a variable resistance to control the pitch.
The oscillators are fed into a resonant low pass filter with a slope of -12dB. The filter cutoff is controlled by the dedicated knob or using the LDR CUT photoresistance, depending on the position of the LDR/POT switch. The RES potentiometer adjusts the resonance of the filter.
Finally, the XXX controller enables transposition.
There is no power supply included in the delivery. It is possible to operate Lumanoise with 9V and with 12V. At 9V the whole device, but especially the filter behaves more smoothly and at 12V the aggresive sound comes out.
Tony Light and Peppo Lasagne have been behind the Milan-based Laboratorio Elettronico Popolare for quite a while now. Not only their small wooden boxes and unusual percussion modules are quite popular, the unusual LepLoop desktop synth has become part of Surgeon's sonic arsenal as of late.
