On this page you can find various information on modular synthesizers, what are they, how do they work and what kind of modular synthesizer is a eurorack module. Also some nice tips on how to work with modular synths, where to start and some help on choosing your modules.
What is a modular synthesizer
According to Wikipedia:
"The modular synthesizer is a type of synthesizer, which exists in both physical and virtual forms, consisting of separate specialized modules. The specialization is usually in the module being designed to allow the modification or processing of one parameter of a signal, such as the frequency (oscillator), spectrum (filter), or amplitude (amplifier). The modules are not hardwired together but are connected together with patch cords, a matrix patching system, or switches to create a patch. The voltages from the modules may function as (audio) signals, control voltages, or logic conditions."
You could say that a modular synthesizer is a musical instrument which you can create yourself. It's like a synthesizer, but instead of heaving a pre-defined setup of possibilities you can now fully create your own flow, sounds, brands, modules and most of all; it is unlimited! You can connect almost everything to anyting you want via (mono) mini-jack cables (3.5mm) also called patch cables.
There is a variation in the format of the modules that can be used. On Eurorackworld we of course focus on the Eurorack format of the modular synths. One of the most common, versatile and amazingly useable formats. Below a picture of various sizes of other formats as well.
