The Lumanoise V4 heve 4 trautonium like sub oscillator. We were inspired by the Oskar Sala Trautonium synth oscillator section. We use a T. master oscillator under LDR control and 4 sub divider oscillator, where you can set the division frequency of the T. master, divider n°4 divide the n°3. Each oscillator have a volume pot, it is possible to connect an external LDR or a variable resistor, a high\mid\low switch for the T. master oscillator range.
A 12 db low pass resonant filter, the filter cut-off can be controlled by the potentiometer or the photo resistor.
Lumanoise works with voltage between 9 and 12 volt
