Which modular synthesizer is best?

Modular synthesizers are one of the more elusive instruments in the modern music world, largely basing their sound on combinations of electrical signals and oscillations. While the best modular synthesizer will largely depend on the user’s needs, most modular synths can, at least, offer thousands of hours of interesting electrical and sonic experiments.

The Moog Grandmother Analog Modular Synthesizer is an excellent modular synth that’s versatile and user-friendly enough to make it suitable for both beginners and experts, and it’s easily a top pick as far as modular synths go.

What to know before you buy a modular synthesizer

Modular vs. semi-modular synthesizer

While modular synthesizers in the past included separate electrical modules, hence the name, most modern synthesizers include multiple modules built into one single keyboard or synthesizer housing. As such, most modular synths today are considered semi-modular synths, even if they can patch in and out like classic modular synthesizers. 

Regular analog synthesizers vs. modular synths

Regular analog synthesizers tend to be enough synth for the average newcomer. Still, many synth enthusiasts love the look, feel and play style of classic modular synths — which explains in part why they’re so pricey. Depending on what you’re looking for in a synthesizer, you may be able to get away with a regular analog synthesizer, although models with modular patching capabilities are the real deal and offer some of the strangest sounds available out there.

Keyboard type

You can find many of the best digital keyboards offering classic piano sounds and fantastic features by simply checking the BestReviews buying guide. However, keyboards on a synthesizer can be a little more confusing to the average consumer. Many modular synthesizers don’t even need a keyboard, especially if they have a strong sequencer, since they’re simply pulsating electrical signals and technically have no “default note” like on a piano. So, depending on how many keys you want or if you need your modular synthesizer to have a keyboard at all, the synth you end up with could vary quite widely.

What to look for in a quality modular synthesizer

Preferred interface

Besides choosing modular synthesizers based on their obvious significance — their sound — many users elect to choose modular synths that feature their preferred interface. While some users can get away with a strong sequencer and no keys on their synth, most prefer a modular synthesizer with a keyboard and the right amount of keys.

Versatile use cases

Modular synthesizers have become less common today, not because they don’t create good sounds, but because their very nature tends to make them a little less versatile than the average synth. Still, most modular synths are useful in their own way, especially if the user knows how to use them. It’s important to find a synthesizer that suits your personal needs and is versatile enough to actually get some use out of them.

Strong sequencer

On modular synthesizers, especially those without built-in keyboards, a strong sequencer is almost essential. The sequencer in a synth creates a series of noises or notes in a loop, and it can be used for a wide range of applications. For example, the sequencer on a modular synth will determine the tempo of the notes being played in series and the number of notes available in a given series.

How much you can expect to spend on a modular synthesizer

The price of modular synthesizers is no joke, with many models costing several hundreds of dollars. While you can find simplified modular synthesizers for as low as $200 and digital synth sounds for even more affordable prices, many modular synthesizers will land somewhere between $500-$2,000.

Modular synthesizer FAQ

Are modular synthesizers obsolete?

A. Modular synthesizers are not obsolete. While most today are considered semi-modular due to their built-in patching to simplify the playing process, you can still find plenty of models that offer just patch cables and no keyboard that feel like the original modular synthesizers.

How are modular synthesizers played?

A. While most synthesizers today are played with the use of a traditional piano keyboard, some modular synthesizers are played by simply using a sequencer of some sort and ⅛-inch patch cables as well as other modules and the many knobs that come with a single synthesizer.
