Lumanoise v3

Eurorack version of the Lumanoise v3 desktop synth

The different Lumanoise models have different oscillator setups but all use the same 12dB/octave resonant LPF.

The Version 3 module has two saw oscillators (3-bit bass frequency and 7-bit high frequency) and a white noise generator. The pitch of the oscillators is controlled by a vactrol with offset and CV amount (range 0-10V, not 1V/Oct). A High/Med/Low switch selects the pitch range of the oscillators. The oscillators and the white noise have separate volume potentiometers which saturate after half the range. The mixed Audio out is available on a mini-jack connector.

The LPF is a simple discrete transistor design created specifically for the Lumanoise family by L.E.P. The filter cut-off frequency is controlled by a vactrol with offset and CV amount (range 0-10V). The resonance frequency can also be adjusted with a potentiometer.
