I’ve been a devoted fan of Serum synth plugin for a long time. Serum 1 was always in my top choice when making music. It was perfect for creating all kinds of sounds, whether smooth background pads, strong basslines, or sharp, quick notes.
The Serum soft synthesizer was always reliable. I appreciated how straightforward it was to use: you could easily drag and drop to modify sounds, it provided obvious audio, and offered countless synthesis possibilities with the wavetable editor.
So, when Xfer Records introduced Serum 2, I felt a mix of excitement and skepticism, but I knew I had to upgrade and give it a chance. Could Xfer truly enhance something already so impressive?
After spending many hours exploring Serum 2, experimenting with factory presets, and crafting drum sounds, lead melodies, and various textures, as well as testing its new routing and synthesis features, I feel confident in saying that this version is a significant improvement.
It’s more than just a simple update; it’s a true evolution! Let me guide you through the changes, highlight what’s truly important, and explain why I believe Serum 2 is one of the most powerful software synthesizers I’ve ever used.
A Fresh Look
While Serum 2’s engine under the hood is packed with new power, one of the first things you’ll notice immediately is how much cleaner, sharper, and more modern the interface feels.
Xfer Records didn’t completely redesign the GUI. They respected the familiar layout loyal users love, but they polished it to feel much more modern, visually refined, and easier to navigate.
Visual transitions feel more fluid, and animated meters look noticeably smoother, particularly on higher refresh rate displays (such as 180Hz in my case). Serum 2’s GUI scales better across high-resolution (HiDPI/Retina) displays without any issues.
The Oscillator Revolution
Serum’s iconic wavetable engine is still very much the heart of its sound design capabilities, but in Serum 2, the oscillator section has expanded dramatically. Instead of simply building sounds from wavetable morphing, you now have five distinct oscillator modes to choose from, each unlocking new dimensions of sonic creativity.
- Wavetable: still the best in the business, now with even smoother interpolation.
- Multisample: load full SFZ instruments and map realistic sounds across the keyboard.
- Sample: here you can drag and drop audio samples and manipulate start/end points, loops, and slices.
- Granular: break audio into tiny grains and reshape soundscapes in ways that rival dedicated granular synths.
- Spectral: manipulate sounds at the frequency level for stunningly unique results.
Each mode is deeply integrated, meaning you can modulate, layer, and route them as easily as traditional wavetables.
The New Mixer
Serum 2’s brand-new Mixer Tab is one of the most significant and most exciting upgrades, and it honestly feels like unlocking a full mini-DAW right inside the synth itself.
In Serum first version, signal routing was pretty straightforward: oscillators could be routed to filters and FX with some basic control. Now, in Serum 2, the Mixer tab makes everything change.
It introduces individual channels for each oscillator, noise, and sub, complete with independent level, pan, and bus send controls.
Now you can:
- Independently pan, level, and route each oscillator
- Send sounds to multiple FX busses simultaneously
- Create punch/crunch layering techniques
- Adjust direct-to-main and filtered signal balances
This is a game-changer for advanced sound designers who want to sculpt exactly how every element flows through effects and outputs.
FX Section Overhaul
Serum 2 introduces two fully independent FX busses (FX1 and FX2), as well as a Main FX chain. The FX section has evolved into a whole, professional-grade audio processing rack, offering flexibility comparable to mixing and mastering plugins.
You can now route different oscillators or layers to separate FX chains. Some of the new FX highlights:
- 13 effects modules, including new stars like Convolve, Bode Shifter, and three new lush Reverb types (Vintage, Nitrous, Basin).
- Multiple FX Buses for complex parallel chains.
- Splitter modules for mid/side and multiband processing.
Now, I can design a full sound, including complex spatial FX, multiband distortion, and stereo widening, without leaving the Serum interface at all.
More Modulation, More Creativity
Modulation has always been one of Serum’s biggest strengths, allowing producers to create lively, animated patches without complicated setups. In Serum 2, modulation is taken to a whole new level: It’s more powerful, flexible, and intuitive than ever before.
Serum 2 now supports up to 10 Low-Frequency Oscillators (LFOs). Each LFO features independent X and Y grids, letting you fine-tune curves and resolution with incredible detail. LFOs can now follow swing settings, meaning rhythmic modulation can groove with your project’s timing!
The result? Ridiculous freedom. I found myself quickly patching complex modulations without feeling overwhelmed. It’s still drag, drop, and done.
Faster and Smarter
One of the smartest aspects of Serum 2 is how much smoother and more intuitive it feels to use. Serum 2 isn’t just bigger, it’s faster, and cleaner, making it an absolute joy to create with, even during complex sessions.
Serum 2 finally introduces comprehensive Undo and Redo across almost all parameters. Whether you tweak an envelope curve, change a routing path, adjust a filter setting, or randomize a wavetable, you can safely revert or reapply your changes.
The new Preset Browser in Serum 2 is much more powerful and user-friendly. Presets are now categorized by type (Bass, Pad, Lead, Keys, etc.) and feel (Soft, Aggressive, Ambient, etc.), making it easy to find what you need.
The good news: every Serum 1 preset, including third-party banks, loads seamlessly into Serum 2. That’s over a decade of sound design legacy, ready to go. On top of that, you get: 626 brand-new factory presets.
The Competition
Today’s synthesizer market is busier and more competitive than ever before. Big names like Arturia Pigments 5, Vital, or Nexus 5 are offering fresh and innovative features. Each of these software synthesizers has its standout qualities.
Arturia Pigments 5 is known for its colorful modulation environment, while Vital offers unique spectral warping capabilities. Nexus 5 comes with sounds that are immediately ready to become hits, and Spire is celebrated for its rich, fat supersaws.
Then there’s Serum 2, which not only competes with these modern synthesizers but also raises the standard to a new level. It comes with enhanced oscillator engines, multi-bus effects processing, and an in-depth approach to modulation.
Serum 2 isn’t about following current trends! It’s about setting trends for what can be achieved in sound design!

Final Thoughts
If you’ve loved Serum 1 like I have, Serum 2 will feel like your old friend leveled up in every way possible. It’s richer, deeper, more flexible, and somehow even more fun.
With its expanded oscillator options, groundbreaking Mixer and FX sections, modular modulation system, and sampling and granular engines, Serum 2 is easily the most comprehensive and creative synthesizer available in 2025.
I can already tell that it will dominate my productions this year, and if you’re serious about sound design, it will dominate yours too!
