In this article, we will explore how modular synthesis works and how you can use it to create your own electronic music. Whether you’re a seasoned producer or just starting out, this guide will provide you with a solid understanding of the basics of modular synthesis and how to get the most out of your setup. So, let’s dive in and discover the world of modular synthesis!

What is modular synthesis?

A brief history of modular synthesis

Modular synthesis is a method of synthesizing sound that involves the use of interconnected modules to create complex sounds. These modules can be anything from simple filters to complex wave generators, and they can be connected in any configuration to create a wide range of sounds.

The concept of modular synthesis has been around since the 1960s, when electronic music was first starting to gain popularity. Early modular synthesizers were large, complex machines that were expensive and difficult to use. However, as technology has advanced, modular synthesizers have become more accessible and affordable, and they have become a popular choice for musicians and producers who want to create unique and custom sounds.

One of the first modular synthesizers was the R.A. Moog Co. Modular Synthesizer, which was introduced in 1964. This synthesizer was a large, complex machine that consisted of a series of modules that could be connected to create different sounds. The Moog synthesizer was used by many famous musicians and composers, including Wendy Carlos, who used it to create the soundtrack for the film “A Clockwork Orange.”

In the 1970s, modular synthesizers became more popular, and a number of companies began producing them. One of the most famous of these was the Roland Corporation, which introduced the Roland System 100 in 1975. This synthesizer was a more affordable and user-friendly alternative to the Moog synthesizer, and it helped to popularize modular synthesis among a wider audience.

Since then, modular synthesis has continued to evolve, and there are now a wide variety of modular synthesizers available, ranging from small, portable systems to large, complex machines. Many of these synthesizers are now available as software, making it possible to create and manipulate sounds using a computer.

Components of a modular synthesizer

Analog oscillators

Analog oscillators are the foundation of a modular synthesizer. They generate sound waves through the use of a simple electronic circuit, which can be modified and shaped by the user. The oscillator is the starting point for all sound generation in a modular synthesizer.

Filters

Filters are another essential component of a modular synthesizer. They process the sound waves generated by the oscillators, shaping and altering them in various ways. There are many different types of filters, each with its own unique sound and characteristics. Some common types of filters include low-pass, high-pass, and band-pass filters.

Amplifiers

Amplifiers are used to boost the volume of the sound waves generated by the oscillators. They are an important part of the signal chain, as they help to shape and define the overall sound of the synthesizer. Amplifiers can be used to add gain, distortion, and other effects to the sound.

Effects modules

Effects modules are used to add various sonic effects to the sound waves generated by the oscillators. They can be used to add reverb, delay, chorus, flanger, and other effects to the sound. Effects modules can be used in a variety of ways, depending on the desired effect.

Control voltage sources

Control voltage sources are used to control the parameters of the various modules in a modular synthesizer. They allow the user to control the frequency, amplitude, and other parameters of the oscillators, filters, and other modules. Control voltage sources can be used to create complex and dynamic sounds.

Modulation and CV connections

Modulation and CV connections are used to connect the various modules in a modular synthesizer. They allow the user to control the parameters of one module with another. For example, the frequency of an oscillator can be controlled by a control voltage source, creating a dynamic and evolving sound.

Understanding the basics of synthesis

Modular synthesis is a powerful technique used to create and manipulate sound. It involves breaking down the sound creation process into several key components: waveforms, timbre, envelope shaping, and modulation. Understanding these components is essential to creating the desired sound.

Waveforms and sound generation

Waveforms are the basic building blocks of sound. They are the patterns of vibration that create sound waves. In synthesis, waveforms can be created electronically using oscillators. These oscillators generate waveforms that can be shaped and modified to create different sounds. The most common waveforms used in synthesis are sine, square, triangle, and sawtooth. Each waveform has its own unique characteristics, and they can be combined to create complex sounds.

Timbre and envelope shaping

Timbre is the unique quality of a sound that allows us to distinguish between different instruments playing the same note. It is the combination of harmonic frequencies that gives a sound its distinctive character. In synthesis, timbre is created by filtering and modifying the waveforms.

Envelope shaping is the process of controlling the volume of a sound over time. It is typically achieved using envelope generators, which are similar to oscillators but shape the volume of the sound rather than the pitch. Envelopes can be used to create a wide range of sounds, from gentle fades to dramatic sweeps.

Modulation and parameter control

Modulation is the process of changing a parameter over time. In synthesis, modulation is used to create movement and interest in a sound. Common types of modulation include LFO (low-frequency oscillation) and ADSR (attack, decay, sustain, release).

Parameter control allows the user to adjust the various settings of the synthesizer. This includes adjusting the frequency and shape of the waveforms, controlling the envelopes, and modifying the modulation parameters. By controlling these parameters, the user can shape the sound to their desired specification.

In summary, understanding the basics of synthesis is essential for creating the desired sound. Waveforms, timbre, envelope shaping, and modulation are the key components of synthesis, and they work together to create the rich and complex sounds that are the hallmark of modular synthesis.

Building a basic modular synthesizer

Choosing a case and modules

Choosing the right case and modules is an essential step in building a basic modular synthesizer. The case is where all the modules will be housed, and it should be big enough to accommodate all the modules that you plan to use. There are various types of cases available, ranging from small desktop cases to large rack-mountable cases. The type of case you choose will depend on your needs and the size of your synthesizer.

When choosing modules, it is important to consider the type of synthesis you want to achieve. For example, if you want to create analog-style sounds, you will need different modules than if you want to create digital-style sounds. It is also important to consider the number of inputs and outputs that each module has, as this will determine how they can be connected to other modules.

Assembling the synthesizer

Once you have chosen your case and modules, it is time to assemble your synthesizer. This involves mounting the modules into the case and connecting them together.

Advanced modular synthesis techniques

Multiple voice and polyphonic synthesis

Multiple voice and polyphonic synthesis are advanced modular synthesis techniques that allow for the creation of complex, multi-layered sounds. In traditional monophonic synthesis, a single voice is generated, which can be played at different pitches. In contrast, multiple voice synthesis generates multiple voices simultaneously, each with its own unique timbre and envelope.

One common technique for generating multiple voices is to use multiple oscillators with different waveforms, and then assign different envelopes to each oscillator. This allows for the creation of complex, layered sounds that can have a wide range of timbres and textures. Another technique is to use sample-and-hold circuits to sample the output of each oscillator and then play back the sampled waveform at a different pitch, creating a new voice.

Polyphonic synthesis is similar to multiple voice synthesis, but instead of generating multiple voices at once, it generates multiple notes simultaneously. This allows for the creation of complex, chordal sounds that can have a wide range of harmonic structures. Polyphonic synthesis can be achieved using a variety of techniques, including adding more oscillators, adding more envelopes, or using more complex modulation schemes.

Overall, multiple voice and polyphonic synthesis techniques allow for the creation of complex, multi-layered sounds that can have a wide range of timbres and textures. These techniques are often used in electronic music production, but they can also be used in other fields, such as film scoring and sound design.
