Modular Synthesis, The Modular Seed
Modular Synthesis. A sound creating set of tools that’s been around since the 50’s is starting to trend amongst musicians and artists today.
Myself falling deep into what you could say is an obsessive compulsive bank breaking hobby, but its totally worth it.
This powerful technique allows you to create intricate and complex pieces of music without needing to use any samples or DAW’s. In this article, we’ll introduce you to modular synthesis and discuss the best modules for creating synthesized music. Let us tune your ears so you can start patching!
What is Modular Synthesis?
A synthesizer module is simply a piece of hardware or software that helps you create sounds. They come in all shapes and sizes, but the most common type are that of Euro rack. The majority of the Modular Synthesis Market has adopted Euro rack to be at the forefront of modular synthesis.
Modular synthesizer systems were first developed in the 50’s by people like Harry Partch and Robert Moog. These early modular systems used sequencer modules to control voltage controlled oscillators (VCOs), waveform generators (WG), filters, and vocoders. These days modular synthesizers are much more complex and allow you to control a wider range of sounds than the early systems could.
One of the best features of a modular synthesizer is that you can create music without any samples or Computer connection.
This makes it perfect for creating synthesized soundtracks, ambient music, experimental electronic music, ultimately a infinite sound creating realm of creative possibilities!
The downside to modular synthesizers is that they’re often expensive and require some understanding of electronics in order to use them effectively. However with comprehensive tutorials online like this one from Eartuned.com, you’ll be patching like a boss in no time!
Control Voltage and Audio Signal
Today there is a staggering number of modules available in various formats, with different styles of sound creation and modulation. There are a few standard module functions that you can see in most keyboard synthesizers and VST’s. Lets run down all the basic functions of your standard modules. Keep in mind on a modular synth there’s only one of two things traveling through those cables connected on the front.
- Control voltage CV– Control voltage (CV) is the voltage that travels between module terminals to modulate audio signals. You can use CV’s to control parameters
- audio signal – Audio signal refers to the analog audio signals that are actually being synthesized and modulated, then output by the modules in your modular setup.
Heres an example of normalised signal path, a map if you will of where the sound travels to and from before finally your ears to hear. this is the signal path for a Behringer Neutron which i own and love!
The audio signal will either be connected directly from an instrument or keyboard into a module input socket on the synthesizer system. Or created from an Oscillator module, or another analog or digital sound source within your modular synth. synthesizer modules have specialized output sockets for sending out audio waveform data along with CV control voltages and other signals generated during synthesis processing to create and modulate your sound.
a list of the basic types of modules.
- VCO – voltage Controlled oscillator module, these will either be an analog or digital Sine, Triangle, Square, Saw,
- VCA – Voltage Controlled Amplifier
- VCF – Voltage controlled Filter module, there are several different kinds of voltage controlled filters which ill cover in another article
- LFO – Low Frequency oscillator module
- ADSR Attack Decay Sustain Release, Envelope generators – ADSR Envelope generator modules let you modulate the amplitude, frequency and/or decay of audio signals over a range of time. envelope generators are used to create effects like vibrato and flanging. There can also be modulation inputs for control voltages or keyboard messages which will affect the ADSR parameters of an envelope module e.g Filter cutoff frequency, resonance etc…
- multiplier module– A multiplier provides a multiplying function between two waveform data streams – e.g., audio and CV modulation signals from different sources within your modular synthesizer setup can be multiplied together by the multiplier to create even more complex modulations and sounds.
- Sample and Hold – This analog modular synthesizer module allows you to control the speed of a sample and hold oscillator by alternatively selecting one of two voltage outputs.
- Sequencer Module – refer to my article on Euro rack Sequencers
- Noise – self explanatory
- mixer module – used for combining multiple signals into one output
Getting Started on a Budget with Your First Modular Synthesizer: The Best Modules & Cases
If you are looking to get started with modular synthesis and save some money in the process, you’ve come to the right place. Whether you are a beginner or a seasoned veteran, this guide will help you get the most out of your modular setup, without breaking the bank.
We’ll be covering all the basics – from the best modules and cases to DIY options and budget-friendly starter synths. So, let’s dive right in and get started!
Introduction to Modular Synthesizers
A modular synthesizer is an electronic music instrument that is composed of interconnected modules that allow users to create sounds by patching them together. The modules are usually housed in a case and are connected with cables. Each module performs a specific function, such as oscillators, filters, and envelope generators.
Using a modular synthesizer, you can create sounds that range from subtle and nuanced to wild and chaotic. The possibilities are truly endless, and the best way to explore them is to dive in and start patching.
Modular synthesis has become increasingly popular over the past few years, thanks to the proliferation of Eurorack cases and modules. Eurorack cases are the most popular type of modular synth case, and they come in a wide variety of sizes and configurations.
Benefits of Using Modular Synthesizers
Using a modular synthesizer offers a number of benefits.
First, it allows you to create sounds that are unique and complex. With a modular synthesizer, you can explore the depths of sound design, and create sounds that are both organic and synthetic.
Second, modular synthesizers are highly customizable. You can mix and match modules to create your own unique setup, and you can also add or remove modules as needed. This flexibility allows you to create a system that works for your workflow and budget.
Third, modular synthesizers are highly portable. Most Eurorack cases are relatively small and can be easily transported to gigs or recording sessions. This makes them ideal for those who need a system that can be easily moved around.
Finally, modular synthesizers are highly affordable. Even if you’re on a tight budget, you can still build a great sounding system. There are a number of budget-friendly modules and cases available, so you can get started without breaking the bank.
Best Modules for Beginners
When it comes to modules, there are a few that are especially well suited for beginners. These include oscillators, filters, envelope generators, and VCAs (voltage controlled amplifiers).
Oscillators are the core of any modular system. They generate the basic waveforms that are used to create sounds. The best oscillators for beginners are those with simple, easy to understand controls. The Doepfer A-110-2 and the Intellijel uFold II are two great options for those just starting out.
Filters are used to shape the sound of oscillators and create unique timbres. The best filters for beginners are those with lowpass, bandpass, and highpass modes, as well as flexibility in terms of cutoff and resonance. The Doepfer A-125 and the Intellijel Shapeshifter are two great filters for beginners.
Envelope generators are used to control the amplitude of a sound over time. The best envelope generators for beginners have simple controls and a range of attack and decay times. The Doepfer A-140 and the Intellijel Plaits are two great options for those just starting out.
VCAs are used to control the volume of a sound. The best VCAs for beginners are those with simple controls and the ability to control multiple signals simultaneously. The Doepfer A-132-4 and the Intellijel Quad VCA are two great options for those just starting out.
