6 Better Serum Alternatives (Free Synths Included)

While there aren’t many synths that are better than the fan favourite, beloved Serum, there are a few good picks (that are free) that match the quality of it. We personally use Serum in everything, and would never replace it, but if you don’t have the budget for it, we understand. In this article, we’ll cover some great Serum alternatives that are free and paid. We’ve tested all of these and chosen them based on merit, using our 8 years of background in music production and sound design.

What is Serum?

In Serum you’ll find a great range of tools to help you design sound, with the possibility to modulate any source, have access to a huge library of wavetables (with the ability to create your own), a huge selection of filters (some unique to Serum that make sound design incredibly intriguing) and a whole lot more.

Although it only has 3 oscillators, it is extremely versatile and has the potential to make anything. With the great sound, light CPU and brilliant design, it’s why it’s loved by so many people.

Is Serum Really That Good?

We have personally used Serum to create entire sample packs from scratch, using layering sound design techniques.

It is extremely versatile if you learn how to use it fully, and is very easy for a beginner to learn and pick up quickly compared to more advanced synths. We personally recommend learning sound design in Serum first before moving on to other synths.

The reason is that Serum has a vast amount of tutorials online, free packs and resources you can use to pick apart sounds and learn what makes them sound that way. Not many other synths have this big library of tutorials available.

You can make real-sounding violins, guitars, deep gritty basses, lush pads, 80s synth wave, and pretty much any genre under the sun, just by utilizing Serum’s fantastic synthesis engine and sampling.

Additionally, inside Serum, you get an in-depth modulation matrix, a huge suite of professional effects, and filters that are unique which I haven’t found in many other synths. These filters are fundamental in creating sounds that make you stand out and sound different.

One downfall is that it can become limited when you progress in your sound design journey, so this is why many look for alternatives.

Anyway, I’ll stop touting the benefits of Serum and leave some sound examples of what we’ve personally made using Serum only:

All patches made in Serum – Purple Slush Lofi Pack

All synths made in Serum – Redd Velvet Hyperpop Pack

I would highly recommend trying the 3-day free trial. However, if you want som

How Can I Get Serum Cheaper?

Some people may look for alternatives due to the high price tag of Serum and don’t know of the RTO plan available on Splice.

Serum Alternatives List

KiloHearts Phase Plant (Best Serum Alternative)

KiloHearts’ Phase Plant synthesizer is a dynamic and robust wavetable synthesizer that grants an innovative means of tailoring sounds. Its varied selection of tools encompasses a hybrid synthesis engine, drag-and-drop modulation, and comprehensive routing selections, rendering it a compelling substitute for Serum.

Phase Plant stands apart from Serum because of its modular construction, giving users the freedom to craft unique signal flows. You start from a blank canvas and are able to load Oscillators, effects, modulation, enveloping modules and more. It is free for you to route the synth however you like, whereas Serum is more robust and doesn’t allow as much creativity.

The Hybrid synthesis engine also sets Phase Plant apart, using a mix of FM, wavetable, subtractive, and sample-based synthesis techniques to provide limitless potential for sound design. You can blend all these types of synthesis together for a truly unique sound design.

However, this makes Phase Plant much harder to learn than Serum. Although the possibilities for sound design are greater, for beginners, this synth is extremely hard to wrap your head around. And, often, less is more (especially when learning).

Additionally, Serum has FM, subtractive capabilities in filter types and oscillators, being able to modulate FM from OSC B to A for instance. This is more stripped back, but don’t be fooled into thinking that more is always better. The possibilities for the sound design you have with Serum are incredibly big, and learning how to use it properly and to its max ability will take a lot of time.

Phase Plant doesn’t allow you to create your own waveforms from samples, and also has fewer online resources for learning. It is more CPU intensive and falls back on the filtering and effects suite when compared with Serum.

Serum comes with some great, unique filters like flanging, phases, and misc filters like all passes that are some of the best I’ve ever used for unique sound design that sets you apart. Additionally, the FX suite is far more in-depth, giving you a better workflow and professional sound.

Phase Plant offers a drag-and-drop modulation system, which simplifies the creation of intricate modulation routings. Its user interface is user-friendly, with an intuitive layout and colour-coded signal flow, making it easy to comprehend.
