Lunar Modulation Center Mk.2

2016-2017 Mk.2 Triangle Core VCO

Oscillator, VCO & LFO
Depth: 1.5 inches

Core Type: Triangle. Uses discrete transistor core design.
The transistors are all on the same IC, very stable design. Surface Mount parts.

Influenced from the Bergfotron Advanced VCO circuit, which is influenced from an old Buchla VCO.

What does this do?
This module is used to generate 1v/octave wave shapes: sine, triange, saw, even harmonic wave, square wave, and ramp wave. It is the bread and butter module for your system. Use this to get some audio sound generated. There is a toggle switch on the top to turn the vco into an LFO. In LFO mode the module has very fine control over the lfo speed.

The most common waves have there own level output knobs. I did this because this module compliments another Blue Lantern VCO called the PTC VCO. By having level control on the waves it gives you finer control for FM duties.

Since this is Triangle core the sync is to die for. It sounds very quantizer like and incredible. I have yet to hear this on other Euro Format vco's out their. The sync knob is used to adjust how strong of a sync effect you want.

PCV jacks are used for the pitch CV control (1v/octave).

The Lunar Modulation Center MK2 has a step wave generator. You patch a wave signal into it and it will reduce it into steps. There is a control the width and you can CV control that. The sound is better then traditional pulse width modulation.

The MK2 version also has level attenuation of the square wave output.
