Eurorack & Modular Synthesizers

About Eurorack & Modular Synths

Modular synthesizers allow you to create a custom synthesizer, piece by piece, then patch those elements together in different ways to create unique sounds. Compared with a typical keyboard synthesizer or synth module, which offer a fixed number of oscillators, filters, modulation sources, and other elements, a Eurorack modular synth rig can be created using whatever synthesizer elements you want. Depending on which modules you choose, you can create sounds with a modular synth that you can’t create any other way.

Euroack Modular Synthesizers

So how do you enter the world of Eurorack modular synthesis? It all starts with a Eurorack case, which provides mounting and power for your modules. You’ll notice that cases list their available space in “HP” (horizontal pitch), and modules list their width in HP, too. As long as your case has more HP than all your modules combined, everything will fit fine. Different Eurorack cases offer different power supplies, and you’ll want to make sure the total mA available is greater than the mA draw of all your modules combined. Once you’ve decided which modules you want, and you’ve chosen an appropriate case for them, you’ll just need some patch cables to begin creating sounds.

Semi-modular Synths

The joy of modular synthesis is in experimenting with different combinations of modules and the ability to re-patch your signal chain on the fly. If you aren’t experienced with patching modules together to create sounds, consider a semi-modular synthesizer module that doesn’t require patching to operate. This way, you can start creating sounds right away, and you’ll also have the patch points needed to connect to a larger modular rig.

Modular Synths at Sweetwater

Not all modular synthesizers are Eurorack format; any synth module that offers patch points for CV and gate signals can be integrated into a modular synth rig. For new synthesists that are just starting out, Sweetwater often recommends a modular synth that you can not only play on its own, but can also use within a larger modular rig. That allows you to start on an instrument that’s highly playable on its own and won’t become obsolete as you start to grow your modular rig. We’ve helped countless musicians begin with modular synthesis, and a little forethought about the sounds you want to achieve will go a long way. If you’re unsure whether or not you’re headed in the right direction, give us a call anytime, and we’ll be happy to talk modular synthesis with you.

Gear Trends: The Explosion of Eurorack

With Eurorack, you decide how your signal is going to flow, and you can reconfigure that signal flow in real time by repatching your modules. And as your creative needs grow and change, you’ll be able to add new modules accordingly instead of buying an entirely new synthesizer.

Must-have Modules for Filling Your Empty Eurorack Synth Slots

When building your dream Eurorack system, you’ll often find that you have empty spaces that are just begging to be filled. Sure, you could put blank panels into those gaps, but here are some slim (8HP or smaller), lower-cost modules that will dramatically increase your modular synth system’s sonic possibilities.
