Chain Reactor
Quadraphonic Voltage Influenced LFO

The Chain Reactor combines two of our classic VILFO modules with two additional free running LFOs to create an endless supply of chaotic fluctuations. VILFO1 and VILFO2 feature our unique voltage influence control. Voltage influence works differently than standard voltage control, it allows the incoming CV to mingle with the LFO waveforms in interesting ways, creating unique modulations and patterns. The output of each VILFO is a voltage controlled variable waveform that shifts from a triangle to square wave.

The Voltage Influence Circuit
A typical Voltage controlled oscillator works by using a CV input to directly control the oscillation frequency. The more voltage sent to the CV input, the higher the frequency of the oscillator. The lower the voltage, the lower the frequency of the oscillator. Voltage Influence works by using the CV input to attenuate the frequency of the oscillator while at the same time injecting some of the voltage from influence CV input to the feedback loop of the oscillator. Results can vary from subtle to chaotic. Subtle results can be similar to tremolo, shuffle, or soft reset while more extreme settings produce glitchy, rhythmic, chaotic fluctuations in the frequency of the oscillator.

A Chain Reaction
Three of the modulation sources within the Chain Reactor are patched together using switched jacks to ceate complex modulations without needing to use patch cables. The output of LFO3 is patched to the influence CV input of VILFO2 and the output of VILFO2 is internally patched to the influence CV input of VILFO1. The fourth LFO is not prepatched but can be used to modulate the waveshape of VILFO1 or VILFO2. The internal routing between modulation sources within the Chain Reactor can be defeated by patching an external CV souce into the module.

Chain Reactor Controls:

VILFO1 Frequency Knob - Frequency control of VILFO1.
VILFO1 Influence CV Knob - Influence CV input (INF CV 1) attenuator.
VILFO1 Waveshape Knob - Output waveform control shifts from triangle (left) to square (right). Also functions as the Waveshape CV input (WS CV 1) attenuator.
VILFO1 INF CV 1 Jack - Influence CV input. Normaled to the VILFO 2 output. Internal routing is bypassed when a patch cable is used.
VILFO1 WS CV 1 Jack - VILFO1 ouput waveshape CV input.
VILFO1 OUT 1 Jack - VILFO1 waveform output.
VILFO2 Frequency Knob - Frequency control of VILFO2.
VILFO2 Influence CV Knob - Influence CV input attenuator.
VILFO2 Waveshape Knob - Output waveform control shifts from triangle (left) to square (right). Also functions as the Waveshape CV input (WS CV 1) attenuator.
VILFO2 INF CV 1 Jack - Influence CV input. Normaled to the LFO3 output. Internal routing is bypassed when a patch cable is used.
VILFO2 WS CV 1 Jack - VILFO2 ouput waveshape CV input.
VILFO2 OUT 1 Jack - VILFO2 waveform output.
LFO3 Frequency Knob - Frequency control of LFO3.
LFO3 Shape 3 Switch - Waveform shape selector switch. Switch between triangle and square wave.
LFO3 Range 3 Switch - LFO3 course frequency range switch. Switch between low frequency oscillator range and audio rate oscillator range.
LFO3 Out 3 Jack - LFO3 waveform output.
LFO4 Frequency Knob - Frequency control of LFO4.
LFO4 Shape 4 Switch - Waveform shape selector switch. Switch between triangle and square wave.
LFO4 Range 4 Switch - LFO4 course frequency range switch. Switch between low frequency oscillator range and audio rate oscillator range.
LFO4 Out 4 Jack - LFO4 waveform output.
