Xfer Serum 2 Review: Is It Worth the Price?

Serum's intentionally crafted, high-quality sounds and room for nearly limitless customization have made it an industry-leading synth engine for 10+ years. Massive artists from many genres use Serum but particularly those that create EDM music like Skrillex, Marshmello, and Deadmau5.

11 years after the release of the original Serum, Xfer Records has officially released Serum 2 as of May 2025–and it's everything producers had hoped for and more. The long-awaited update brings significant new features while maintaining the intuitive workflow that made the original so great. Whether you're a bedroom producer or a chart-topping artist, chances are, Serum 2 deserves a place in your music arsenal.

What Is Xfer Serum 2?

Serum 2 is an advanced hybrid synthesizer that combines the original's acclaimed wavetable synthesis with new oscillator types, flexible effect routing, and enhanced modulation capabilities. The main feature is a new Oscillator Section that allows for multi-samples, samples, granular oscillators, and spectral synthesis, further enhancing Serum's sonic palette.

Serum 2 has a wide range of tones with a main focus on synth, bass, pad, and lead patches. While Serum 2 still finds room for vox, brass, piano, keyboard, string, woodwind and more tones (outside of synths), Serum 2 puts most of its focus on synth presets.

Key Specifications:

• Price: $250
• Upgrade: Free for existing Serum 1 owners
• Platform: Windows & macOS
• Formats: VST, AU, AAX
• System Requirements: Modern multi-core processor, 4GB RAM minimum

Serum 2 New Features

Enhanced Oscillator Section

The new Oscillator section allows users to experiment with new sound synthesis methods, including:

• Granular Synthesis: Perfect for creating evolving textures and atmospheric sounds
• Spectral Synthesis: Advanced harmonic manipulation for complex timbres
• Multi-sampling: Import and manipulate your own samples with wavetable precision
• Sample Oscillators: Traditional sampling with modern wavetable processing

Large Built-in Library

Serum 2 starts with 626 presets, 288 wavetables, and a large collection of samples. Serum is also incredible well supported with thousands of official and 3rd party preset packs for every genre and music style.

Improved User Interface

UI changes reduce tabbing and streamline workflow, making sound design more intuitive than ever. The visual feedback system that made Serum so popular has also been refined for even better real-time visualization.

Advanced Modulation System

Changes to the modulation system provide more routing options and deeper control over your sound design. The expanded modulation matrix offers unprecedented creative possibilities.

One of Serum 2's most welcome additions is the integrated arpeggiator, eliminating the need for external MIDI plugins or DAW-specific arpeggiators. The arpeggiator features comprehensive pattern control with up to 32 steps, allowing for complex rhythmic sequences that go far beyond simple up-down patterns.

The arpeggiator includes multiple playback modes (up, down, up-down, random, and custom patterns) with adjustable gate times, swing, and velocity controls. What sets it apart is the ability to create custom step patterns where each step can have different velocities, gate lengths, and even pitch transpositions. This makes it particularly powerful for creating evolving basslines, plucked sequences, and rhythmic lead patterns that are essential in modern electronic music production.

Clip Sequencer Integration

Serum 2 introduces a clip sequencer that allows users to create and trigger musical phrases directly within the synthesizer. This feature bridges the gap between synthesis and composition, enabling producers to craft complete musical ideas without leaving the plugin interface.

The clip sequencer supports both note and automation data, meaning you can sequence not just melodies but also parameter changes, filter sweeps, and modulation movements. Each clip can be up to 64 steps long with variable step lengths, and multiple clips can be chained together for longer compositions. The sequencer integrates seamlessly with the arpeggiator, allowing users to arpeggiate sequenced clips or sequence arpeggiated patterns.

This workflow is particularly valuable for electronic music producers who want to quickly sketch ideas or create self-contained musical loops. The sequencer can sync to your DAW's tempo or run at its own independent rate, making it versatile for both studio production and live performance scenarios.

This makes it particularly powerful for creating evolving basslines, plucked sequences, and rhythmic lead patterns that are essential in modern electronic music production.

Enhanced Filter Section

More filters have been added, giving producers additional sonic shaping tools. Each filter type maintains Serum's signature clean, musical character while adding new creative possibilities.

Sound Quality Analysis

Serum is widely regarded as a modern classic in wavetable synthesis, with its visual workflow making sound design accessible even for beginners, while advanced users can dive into endless modulation possibilities. The sound quality remains pristine, with the new oscillator types expanding the sonic palette dramatically.

Frequency Response: Crystal clear across the entire spectrum

Dynamic Range: Excellent headroom and dynamic response

CPU Efficiency: Optimized for modern systems while maintaining high quality

Aliasing: Minimal thanks to advanced anti-aliasing algorithms

Who Should Buy Serum 2?

Perfect For:
