Undulae Legato Strings for Serum 2: is this $24.99 stack worth it for Music & Sound Design?
Legato strings for Serum 2: the $24.99 pack for producers tired of stiff sample libraries
If you have ever tried to program a cello line in Serum and ended up with a sound that feels like a robot is playing a violin through a tin can, you know the frustration. Standard string sample libraries often lack the fluid, expressive legato that makes a string section feel alive, while purely synthetic patches can sound cold and disconnected. (Undulae Legato Strings for Serum 2)
Undulae Legato Strings for Serum 2 is a compact, $24.99 preset pack from Undulae Music designed specifically to solve that expressiveness gap. It doesn’t just give you static sounds; it provides a framework for automation that mimics how a real performer breathes into a phrase. If you are working in Ableton Live 12 with Serum 2 and want your string lines to feel human without hiring a session player, this is a sharp, low-cost tool to add to your workflow.

| One-line take | A focused, automation-heavy pack that prioritizes realistic legato performance over static sample switching. |
What you’re actually buying
At $24.99, you are not buying a massive library of static samples. You are buying a specific solution to a specific problem: making synthetic strings sound like they are being played by a human with a bow. The core of the Undulae Legato Strings pack consists of three dedicated presets: a Legato Cello, a Legato Viola, and a Legato Violin. These are not just one-knob presets; they are built around a macro system that you are expected to automate to mirror the dynamics of a real performance.
The pack also includes a “Saxolin” preset, a bonus that came from the developer’s attempt to recreate Colin Stetson’s saxophone playing in Serum. While it is a different instrument, it serves as a useful stepping stone for understanding the modulation techniques used in the string patches. Perhaps most valuable for beginners is the included Ableton Live 12 demo project, which features a realistic depiction of Bach’s Cello Suite No. 1 in G, Prelude. This project acts as a masterclass, showing you exactly how to use the Legato Cello patch to create a convincing performance. (Undulae Legato Strings for Serum 2)
The entire download is only 289 KB, meaning it installs instantly and takes up no meaningful space on your drive. You get a tight, focused toolkit that forces you to engage with the performance aspect of your music rather than just hitting keys. It is a “learn by doing” resource as much as it is a sound pack.

Why it’s on our radar
This pack stands out because it is honest about its limitations and its requirements. Most preset packs promise “instant magic,” but Undulae Music explicitly tells you that to get convincing results, you must take the time to automate the macros. This is a refreshing approach for a tool that targets a specific job: creating expressive legato lines in Serum 2. (Undulae Legato Strings for Serum 2)
The inclusion of the Bach Prelude project is a strong signal of quality. It moves the product from being just a sound file to being an educational resource. You can open the project, see how the macros are moved to create the phrasing, and apply that same logic to your own tracks. It is a rare $24.99 purchase that offers a tangible skill upgrade alongside the sound design. (Undulae Legato Strings for Serum 2)
A Gumroad review highlights the quality of that educational component, noting: “Fantastic work, the demo project with the cello has so many details and plays so well.” This confirms that the pack delivers on its promise of providing a detailed, playable example rather than just a static preset.
What actually matters
Before you buy, you need to understand the technical constraints and the workflow required to get the best out of these patches. (Undulae Legato Strings for Serum 2)
- Sample Rate is Critical: The seller explicitly states that these patches only sound as intended at a sample rate of 44,100 Hz. The Convolve effects used to mimic the resonant body of the instruments change drastically at higher rates. At 48,000 Hz, they still sound like strings but with unpleasant resonance. At 96,000 Hz, they sound “awful and not even remotely convincing.” If your project is set to 48k or 96k, this pack will not work for you. (Undulae Legato Strings for Serum 2)
- Automation is Mandatory: The presets are not “set and forget.” The seller warns that if you hate automating macros, this is not for you. The realism comes from moving the modulation parameters to mirror a human performer. If you want a static sound, look elsewhere. (Undulae Legato Strings for Serum 2)
- MPE is Not Mapped: The presets are not mapped to MPE (MIDI Polyphonic Expression) controls because the developer does not own a compatible controller. You can map your mod wheel or pressure to the existing macros, but you will have to do the mapping yourself and test it to ensure it feels right. (Undulae Legato Strings for Serum 2)
Mid-check
If you work in Serum 2 at 44.1kHz and you are willing to put in the effort to automate your macros for a more human sound, this is a highly specific and effective tool. (Undulae Legato Strings for Serum 2)
FAQ
Does this pack work with Serum 1? No, the presets are specifically built for Serum 2. The features and modulation architecture of Serum 2 are required for the patches to function as intended. (Undulae Legato Strings for Serum 2)
Can I use this in Logic Pro or FL Studio? The presets are for Serum 2, which is a standalone plugin. If your DAW supports VST/AU plugins, you can use Serum 2 inside it. The included demo project is for Ableton Live 12, but the presets themselves will work in any DAW that hosts Serum 2. (Undulae Legato Strings for Serum 2)
Is this a sample library? No, it is a preset pack for a synthesizer. You are not downloading audio samples of a cello; you are downloading the settings that make Serum 2 sound like a cello. This means you can change the notes and dynamics in real-time, but you must understand the limitations of synthesis compared to recording. (Undulae Legato Strings for Serum 2)
Why is the file size so small? At 289 KB, the file is small because it contains only the preset data and the project file. There are no large audio samples included, which keeps the download fast and the storage footprint minimal. (Undulae Legato Strings for Serum 2)
Bottom line
Undulae Legato Strings for Serum 2 is a niche tool for a specific need. If you are producing music that requires expressive, legato string lines and you are using Serum 2 at 44.1kHz, this $24.99 pack is a worthwhile investment. It gives you the presets, the educational demo project, and the framework to make your strings sound human. If you need MPE support out of the box or work at higher sample rates, skip it. But if you are willing to engage with the automation to get that realistic bow feel, Undulae Legato Strings for Serum 2 is a sharp, honest, and effective addition to your sound design toolkit.
