This instrument can be a little intimidating for those who are new to the world of electronic music production, but don’t worry, we are here to help! This article will explain what modular synthesizers are, provide tips on how to use them, and answer frequently asked questions.
What Is a Modular Synthesizer?
A modular synthesizer is a type of electronic music device that allows the user to create their own unique sounds by patching together various modules. These modules can include oscillators, filters, envelopes, and more. Modular synthesizers differ from other types of synthesizers in that they are not limited to any one specific sound or function. Instead, they offer the user a wide range of possibilities for sound creation.
If you are new to the world of modular synthesizers, don’t worry, there are plenty of resources available to help you get started. In addition to this article, we recommend checking out some of the following resources:

Now that we’ve answered some common questions about modular synthesizers, let’s take a look at some tips on how to get started using them. [1]
Types Of Modules
Modular synthesizers come in all shapes and sizes, with each module having a specific function. The most common types of modules are:
- VCO: Generates audio signals of different frequencies
Voltage-controlled oscillators are the heart of any modular synth. They generate audio signals of different frequencies, which can be manipulated by other modules in the system. The frequency of a VCO is determined by the voltage applied to its control input.
- VCF: filters sound frequencies to change the waveform
Voltage-controlled filter modules are used to alter the sound waveform by filtering out certain frequencies. The cutoff frequency is the voltage-controlled point at which the filter begins to take effect, making it possible to create filters that change sound over time.
- VCA: controls the amplitude (loudness) of the signal
Voltage-controlled amplifier modules are used to control the amplitude (loudness) of the signal. The level of the output signal can be controlled by a voltage, which makes it possible to create fading or gating effects.
- LFO: produces low-frequency sound waves, typically below 20Hz
Low-frequency oscillator modules are used to produce modulations at low frequencies, typically below 20Hz. These modulations can be used to create vibrato or tremolo effects, or to modulate other parameters of the synth such as the cutoff frequency of a filter.
- Envelope generator: the module creates envelope shapes that can be applied to other aspects of the audio, like the VCA
Envelope generator modules are used to create envelope shapes that can be applied to other modules, such as the VCA. Envelopes typically have four stages: attack, decay, sustain, and release. The time taken for each stage can be controlled, which makes it possible to create a wide range of different envelope shapes.
- Keyboard: used to play notes and send pitch voltages to other modules
Keyboard modules are used to play notes and send pitch voltages to other modules. Some keyboards can also generate gate signals, which can be used to trigger envelope generators or other modules.
- Sequencer: generates a series of voltage steps that can be used to control other modules
Sequencer modules are used to generate a series of voltage steps that can be used to control other modules. This makes it possible to create repeating patterns or melodies.
- Arpeggiator: generates a series of notes based on the notes played on the keyboard
Arpeggiator modules are used to generate a series of notes based on the notes played on the keyboard. This can be used to create arpeggio effects or complex chord progressions.
- Noise generator: produces random voltages that can be used to create noise effects
Noise generator modules are used to produce random voltages that can be used to create noise effects. White noise generators produce a uniform distribution of frequencies, while pink noise generators have a distribution that is weighted towards lower frequencies.
- MIDI interface: the modular synth can be MIDI-controlled, meaning that devices like keyboards and computers can send data to it
MIDI interface modules are used to allow the modular synth to be controlled by MIDI devices such as keyboards and computers. This makes it possible to use the synth as a controller for other MIDI devices, or to record and playback MIDI sequences. [2]

Technical specifications
Modular synthesizers are an electronic musical instrument that can be used to create any sound from simple basslines, textures and pads. Connecting modules together with patch cords creates the variety of sounds this synth offers.
Form Factors
Most modular synthesizers come in one of three form factors: desktop, Eurorack, and large-format. Desktop modules are self-contained units, often with their own power supply, keyboard, and other controls built in. Eurorack modules are standardized units that fit into a larger chassis (called a rack) and share a common power supply. Large-format modules are similar to Eurorack modules, but are much larger in size.
Electrical
Electrical engineering has come a long way since the days of vacuum tubes and electromechanical relays. In the early 20th century, these were state of the art technologies that powered everything from radios to computers. But by the end of the century, they had been replaced by semiconductor-based devices such as transistors and integrated circuits. Today, electrical engineers continue to push the boundaries of what is possible, making ever smaller and more powerful devices. One area of recent interest is in modular synthesizers. [3]
Semi-Modular Synthesizers
A semi-modular synthesizer is an electronic musical instrument that consists of multiple modules, each with a specific function. These modules are usually connected together with patch cords, and the arrangement of these connections determines the sound produced by the synth. Modular synths can be used to create any number of sounds, from simple basslines to complex textures and pads.
Matrix Systems
A matrix system is a type of modular synthesizer that uses a grid or matrix to connect different modules together. The most common type of matrix system is the 16×16 matrix, which has 16 inputs and 16 outputs. Matrix systems are very flexible, as they allow you to connect any input to any output. This means that you can route any signal to any module, which gives you a lot of control over the sound. Matrix systems are often used in live performance, as they allow you to quickly change the routing of signals on the fly. This flexibility comes at a price, however, as matrix systems can be very expensive.
Patch Override Systems
One of the systems that you’ll encounter while shopping for a modular synthesizer is a patch override system. This type of system is designed to give you more control over your sound by allowing you to “patch” or route different signal sources to different destinations within the synth. While this may seem like a relatively simple concept, it can have a profound impact on the way your modular synthesizer sounds.In a typical patch override system, you’ll have a series of input jacks (typically located on the front panel of the synth) that you can use to route any signal source into the synth. Once the signal is inside the synth, you can then use the patchbay to route it to any of the destinations within the synth. This gives you a tremendous amount of flexibility in terms of how you use your modular synthesizer.
Electronically Reconfigurable Systems
The term modular synthesizer can be used to describe any type of electronic system that is capable of being reconfigured by the user. This includes both analog and digital systems, as well as hybrid systems that combine elements of both. Modular synthesizers are often created by manufacturers as kits that can be assembled by the user, or they may be assembled from individual components that the user purchases separately. The advantage of modular synthesizers over other types of electronic musical instruments is that they can be customized to meet the specific needs of the user. This allows the user to create sounds that are not possible with other types of instruments. There are two main types of modular synthesizers: analog and digital. Analog modular synthesizers use analog signal processors to generate and process sound. These types of synthesizers are often preferred by musicians who want to create vintage-sounding music. Digital modular synthesizers, on the other hand, use digital signal processors to generate and process sound. Musicians who want to produce modern sounding music typically prefer these types of synthesizers. Hybrid modular synthesizers are also available, which combine elements of both analog and digital synthesizers. There are several factors to consider when choosing a modular synthesizer. The first is the type of sound that you want to create. If you’re looking to create music that sounds like it’s from a bygone era, an analog modular synthesizer is probably your best bet. If you want to create more modern sounding music, then a digital modular synthesizer is likely to be the best choice. With prices ranging from a few hundred dollars to several thousand, modular synthesizers offer an amazing variety of sounds for any budget. The next point to think about is how big the unit is. Some modular synthesizers are very small, while others are quite large. The fourth factor to consider is the power requirements. Some modular synthesizers require a lot of power, while others do not.The fifth and final factor to consider is the level of complexity. Some modular synthesizers are very simple and easy to use, while others are more complex and difficult to use. If you are a beginner, it is probably best to choose a modular synthesizer that is relatively simple to use.Once you have considered all of these factors, you should be able to narrow down your choices and choose the best modular synthesizer for your needs. [4]
Hybrid Modular Synthesizers
In recent years, a new breed of modular synthesizer has been gaining in popularity: the hybrid modular. As the name suggests, these devices combine features of both Eurorack-style and desktop modules, giving users the best of both worlds.
One of the most notable hybrid mods on the market is the Make Noise 0-Coast. This unique instrument combines a traditional analog synth voice with a digital sound engine, allowing users to create rich, complex timbres that would be difficult to achieve with either type of synth on its own.
If you’re looking for a modular synth that offers the best of both worlds, a hybrid modular is an excellent choice. [5]
