Description

This tutorial explores how to use both the VCO and XCO modules by Bogaudio.

Learn about VCOs

A VCO is a Voltage Controlled Oscillator. An oscillator creates cycles in a medium. The medium we use in Modular Synthesis is voltage. In the case of the two oscillators we are examining here, the oscillating voltage is interpreted as sound.

Learn how to choose waveforms

Both the VCO and XCO provide pure waveforms in types: sine, triangle, saw and square. We can further manipulate and combine these waveforms to create unique sounds using the modules.

Learn how to switch VCO and XCO to LFO-mode

Both oscillators here can function as either a VCO or as an LFO. As a VCO both will produce audible sound. As an LFO the output is control voltage and is intended to control other modules.

Learn how to control the module with voltage

There are several inputs on both the VCO and XCO modules. In the video we examine how these inputs can use control voltage to manipulate the module.

Learn the purpose of Hard Sync

After an oscillator has operated for a period of time the waveform can drift. This means that the cycle produced by the module is no longer exactly in sync with other modules. This drift can be a millisecond, but can cause the audio signal to distort. Sync resets the waveform to its original position at the zero start point.

Learn how to independently manipulate each waveform

XCO provides us with controls to manipulate each of the four waveforms. Each has its own unique effect which are explored in the video tutorial.

Each waveform also has a Phase control, which allows us to change the phase of each wave with respect to the other three.

I hope you enjoy this tutorial. If you have any specific questions for me feel free to leave it in the comments of this post and I will do my best to get back to you with an answer.
