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.\u003c\/p\u003e  \u003ch3\u003eThe Voltage Influence Circuit\u003c\/h3\u003e  \u003cp\u003eA 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.\u003c\/p\u003e  \u003ch3\u003eA Chain Reaction\u003c\/h3\u003e  \u003cp\u003eThree 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.\u003c\/p\u003e  \u003ch3\u003eChain Reactor Controls:\u003c\/h3\u003e  \u003cul\u003e \u003cli\u003eVILFO1 Frequency Knob- Frequency control of VILFO1.\u003c\/li\u003e \u003cli\u003eVILFO1 Influence CV Knob - Influence CV input (INF CV 1) attenuator.\u003c\/li\u003e \u003cli\u003eVILFO1 Waveshape Knob - Output waveform control shifts from triangle (left) to square (right).
