But why is it so hard to find a decent synth plugin?

No doubt, synthesizers have continued to evolve in recent years, perhaps beyond everyone’s expectations.

Granted, synths have become must-have providers of breathtaking sonic possibilities for so many musical genres.

But with all the old and new arrivals, one thing is for sure- all available synths aren't the same. While some give so much control and sound-shaping possibilities, others are somehow limiting.

So maybe you’ve already been thinking about getting one or two useful synth plugins but can’t figure where to start?

Fortunately for you, here you‘ll find some great options for out of the box music production.

Want to know more? Stay with me…

The 10 Best Synth VST Plugins of 2021 include:

1. Native Instruments Massive

Native Instruments Massive

If you've been in the business of music production, then the Native Instruments label needs no introduction.


It’s merely one of the most popular of quality VST plugins producers around.

Back to this- Massive is NI’s hybrid synth anchored on ideas and inspirations from wide-ranging sources.


You must be wondering what its most exceptional offerings are.

Well, it features an extensive collection of wavetable oscillators, which makes it possible to generate different sounds.

Think of anything from plain analog-style to more complex and evolutionary sounds and everything thereabout.

With the wave oscillators, you can gradually adjust waveforms using a dedicated knob to match your needs.

What else?

Eight intuitive macro controls you can connect to your midi controller.

You have an ingenious modulation mechanism that makes everything easy to program.

And considering Massive comes with about 600 presets, you won’t have to sweat it out to enjoy the full potential.

2. Lennar Digital Sylenth1

Lennar Digital Sylenth 1

If you’ve ever thought of investing in a virtual analog VSTi synthesizer, maybe this could be it.

On the face of it, one can quickly rule it out.


There are so many alternative analog synths in the market (perhaps with a better visual appeal).

So why should anyone pay attention to the Lennar Digital Sylenth1?

To begin with, the Sylenth1 is built from the producer’s perspective.

It only means you can expect far better performance.

And it does so producing superior quality sound with clarity and realism second to none.

How cool?

I should mention- the drivers behind the impressive functionality include four unison oscillators, two innovative filters, and multiple modulation options.

And that’s not all.

The puzzle is completed by the Master FX section, which features up to seven pro-grade sound effects and an arpeggiator.

If you are bothered about getting your hands dirty, not by any chance.

The interface makes interaction seamless, so nothing hinders your creativity.
