Whether you are a classical musician or a modern songwriter, strings can be the very life of your music.
In a nutshell, here are the best orchestral strings plugins to get in 2025:
2. Spitfire Audio – Abbey Road: Iconic Strings 2
3. SWAM Solo Strings Bundle V3
5. Orchestral Tools – Berlin Symphonic Strings
6. UJAM – Symphonic Elements STRIIIING
Strings are one of the most important sets of instruments in classical music, and they can provide an extensive range of mood and emotion to modern music.
While solo strings are beautiful, ensemble strings excel at creating rich and colorful textures in which other instruments can thrive.
We will go from rich, orchestral libraries to budget all-rounders and modern contenders laser-focused on music production. And at the end of the list, you’ll find four free strings plugins that sound very usable and possibly all you need for commercial music.
Note: The strings plugins we have enlisted have their own dedicated plugins, which can be both good and bad. Often, they provide better stability and easier workflow, but you miss out on some functionalities that samplers like Kontakt 6, Halion 6, or UVI Falcon 2 provide. Hence, we will be writing another list review focusing on Kontakt libraries.
Now, let’s dive right in!
The 6 Best Strings Plugins 2025
1. VSL – Synchron Strings Pro
Vienna Symphonic Library is responsible for some of the best sampled orchestral instruments, and Synchron is certainly one of them.
Synchron Strings Pro is a string library recorded in Synchron Stage, Vienna, and it features a massive arsenal of articulations with unparalleled sampling and programming. The result is a highly natural-sounding string library, capable of simple pad-like long notes or energetic runs alike.
I must note that due to the sheer size of the library (over 122 GB for the smaller version), it might be overkill if you are looking for a backing section for pop music or so.
However, if you enjoy composing classical music, Synchron Strings Pro stands as one of the best strings plugins that money can buy.
Key Features:
- Natural Articulations
The instrument features an extensive collection of articulations and expressions, including standard ones like legato, staccato, spiccato, tremolo, etc., and special ones like harmonics, col legno, flautando, and legato agile, which is ideal for fast, bouncing runs.
- Multiple Mic Positions
The Synchron Strings Pro was recorded using 8 microphones. And the library has a Standard and a Full version, where the latter has all the 8 microphones available for adjustments. The standard version has a close mic, mid mic (front row), room mic (L/R), and room mic (center).
- Immersive
Let’s continue from the previous feature. The Full version employs four more mics, including a back mic (second row), main surround mic, high stereo mic, and a high surround mic. They are primarily for creating immersive surround sound, including 2.0.2 (stereo with height audio) and 5.1.4 (Aura 3D or Dolby Atmos setup).
- Presets
The library features many presets that include per-ensemble preset, mapped tutti, and octave combinations employing two ensembles for a fast workflow. Most presets feature multiple articulations that you can switch on the fly and polyphonic legato.
Compatibility:
This library is available for Windows 8.1 or higher and macOS 10.10.5 or higher, both 64-bit only. It comes in VST 2/3, AU, and AAX formats.
2. Arturia Augmented STRINGS
More Info & Price (Trial Available)
Experience acoustic string sets in a refreshed way like you’ve never heard before.
Similarly to the aforementioned Augmented Voices, Arturia brings a refreshed and modern approach to string sets with Augmented Strings. The perfect blending between the samples of string sets with bold synthesized sounds is the recipe for inspiring new sound layers and eccentric ambient sounds with extremely intuitive controls.
Key Features:
- Morph control
The big knob in the center is the soul behind this plugin’s functions. By tweaking it around, you can blend synthesized layers “A” and “B,” with further addition of setting the nearby parameters to better adjust this union. You can alter both layers or one of the two at a time if desired.
- Fresh design
The Augmented plugin series shares a common trait: all effects bear a very fresh-looking user interface. Most people are not familiar with this particular effect, so Arturia thought of displaying every parameter and preset selection in the most fluid, intuitive way possible. It won’t be hard to get big sounds from this collection.
- Presets
Containing a big collection of factory presets, Augmented Strings is fully packed with inspiring configurations for the most diverse situations. You can choose between types like “Bowed Strings,” “String Ensembles,” and “Arpeggio,” for instance, from multiple sound designers and even by the best-suited music style to fit your track.
- Color knob
One of the many macro effects included the “Color” knob is ideal for adding some color to your frequency spectrum. You can easily enhance certain harmonics to your signal, affecting the sound engine behind both layers “A” and “B” simultaneously, with up to six destinations for your sound’s texture.
- Arpeggiator
Going further in the “Advanced Panel,” you’ll see that Augmented Strings has some cool features that are worthy of a good synthesizer unit. The “Arpeggiator” section includes a sequencer that deals with up to 16 steps for creating the best rhythmic pattern for your song.
Compatibility:
This plugin is available for macOS 10.13 or higher (64-bit only) and Windows 8.1 or higher (64-bit only). It runs in standalone mode and VST, NKS, AAX, and AU plugin formats.
3. Spitfire Audio – Abbey Road: Iconic Strings 2
Discover the sound of strings at a legendary studio with this detailed sample library by Spitfire Audio.
Abbey Road has represented the epitome of fame a music studio could have throughout modern music history. And since its opening back in 1932, the Abbey Road Studio Two has remained the most renowned studio space ever, thanks to notable recordings by The Beatles, Pink Floyd, Oasis, Adele, Ed Sheeran, etc.
Spitfire Audio’s Iconic Strings 2 virtual instrument allows you to bring the same acoustic space to your music studio with in-depth sample recordings. There are two editions of his sample library: Core and Professional. The Core is the smaller library with only 46 GB of sample content, whereas the Professional sizes at a whopping 292 GB.
I’ll be describing the Professional edition for this review. However, I’d recommend you check out the Core edition if budget and disk space are issues.
Key Features:
- The Instruments
The plugin features five of London’s top string players playing the following instruments: violin 1, violin 2, viola, cello, and contrabass. Each includes many articulations, playing styles, multiple dynamic layers, round robins, etc., that help create authentic string parts.
These include everything from traditional legato, pizzicato, spiccato, spiccatissimo, staccato, etc., to sul pont, sul tasto, flautendo, brushed, etc. In total, there are 112 articulations.
- Technique Triggers
Iconic Strings offers five ways to trigger articulations or techniques. These include key switches, CC, velocity, MIDI channel, and playing speed. Key switches allow you to change the articulation by pressing a configurable note on your keyboard, usually on your keyboard’s lowest and highest octaves.
- Performance
Iconic Strings comes with various options and features that may help you get the most out of your performance. First, Neighbor Zone RR doubles the round-robin count using transposed adjacent samples. Similarly, Layer x2 modes play two round-robin samples together to thicken the sound. And Layer +2 or -2 layers the round-robin notes two semitones above or below the note you’re playing.
- Arranger
The Arranger section is only available for ensemble patches, which spread all five of the instruments in the plugin across your keyboard. You can change the playable range of each instrument and allow polyphony per instrument or stick to monophony. You can also overlap two or more instruments.
- Microphones
There are eight microphone positions in Iconic Strings. These include the Decca Tree-inspired LCR 1 with three Neumann M50s and LCR 2 with three REDD 47 mics. Similarly, the Close Condenser configuration uses a condenser mic on each instrument: Neumann KM86 for violins, KM140 for the viola, and UT FET47 on the cello and bass.
Further, the Close Ribbon uses Coles 4038 mics on each instrument, whereas Close Vintage uses Neumann KM54 on the violins & viola and U47 on cello & bass.
- Effects
The Iconic Strings plugin has the acoustic space of Abbey Road Studio Two. So, you’ll find a small amount of built-in reverb, although it’s rather raw, dry, and up close. However, it also features a Reverb knob that lets you add additional reverb to your sound. Furthermore, you’ll find a Compress knob that adds a fixed 2:1 compression.
Compatibility:
Iconic Strings is available for Windows 7 or higher and macOS 10.10 or higher, both 64-bit only. It comes in VST 2/3, AU, and AAX formats.
4. UJAM – Symphonic Elements STRIIIING
More Info & Price (Trial Available)
One of the unique strings plugins on our list, STRIIIINGS, is where modern music production meets classical music.
STRIIIINGS was recorded at award-winning composer Hans Zimmer’s Control Studios. And as with any Ujam instrument, the plugin focuses on being intuitive and easy. It doesn’t provide you control over every section and mic placements. Instead, it gives you a broad sense of control and inspiring phrases.
The plugin also features several built-in sound design effects, which allow you to create atmospheres and textures right from the interface. Furthermore, you can use the filters and saturations to create risers and drones for cinematic projects.
Key Features:
- The Interface
Apart from having 200 presets, the plugin also offers a wide range of settings. For instance, you can make global adjustments to the audio using 25 presets and a unique Finisher knob. You can fade between the low and high strings using the highlighter knob, resulting in thrilling risers. The ambiance knob adds reverb to the master signal.
- Low and High
There are two ranges of strings in the plugin: low and high. Cellos and double basses with a variety of effects and two buses are found in the lower strings. The high strings include violas and violins, as well as effects and two more busses.
Both strings feature a Decay and Link control, allowing you to mix and match them. Each string type has a power button, allowing you to activate each one independently.
- Phrase Timing
The plugin features a smooth timing control internally. For example, STRIIIINGS continues to play even you assign the instruments to perform in half or double time using the Micro Timing option. Similarly, the Swing Control is useful for delaying off-beats to get groovy rhythms.
Furthermore, each of the two string sections allows you to assign one character FX and one motion FX on a more intimate level. The former is oriented towards compression and saturation, while the latter leans towards delays and chorus.
Compatibility:
The plugin is available for Windows 7 or higher and macOS 10.12 or higher, both 64-bit only. It comes in VST 2/3, AU, and AAX formats.
5. SWAM Solo Strings Bundle V3
Stefano Lucato and the rest of the Audio Modeling team created the SWAM Solo Strings library to serve as a resource for musicians who perform on solo string instruments.
These tools don’t require samples because they’re built on Physical Modeling technology. You can use a bow or finger pizzicato to simulate playing any SWAM Solo Strings product. Finally, several extra parameters to govern the instrument behavior are available and are not found in the normal SWAM controls.
Key Features:
- Four Instruments
SWAM Solo Strings Bundle includes Violin, Viola, Cello and Double Bass.
- Controller Mapping
You can map an external MIDI controller to the instrument’s controls in the corresponding section. In this perspective or setting, the parameters set for a controller are shown in purple, surrounded by dashed lines, whereas the parameters that have not been set for a controller are shown in green.
- Articulations
There is also a weedy col legno option for the solo strings that lacks real force, in addition to the more powerful straight arco bowing and the modest-sounding pizzicato. There is also a sordino button, which darkens and softens the sound, as well as good harmonics and variable tremolo speed.
- Microtuning
Their method of microtuning allows for a great deal of customization, with scales that the player creates, and the degree of detuning (in the range of +100/-100 cents) controlled individually for each note via a set of sliders.
Compatibility:
The library is available for Kontakt 5.7 or higher (NOT the free Kontakt Player). Kontakt 5.7 is available for Windows 7 or higher 32-bit and 64-bit and macOS 10.10 or higher 64-bit. It comes in VST 2, AU, and AAX formats.
6. Orchestral Tools – Berlin Symphonic Strings
Find realism and soaring expression with the Berlin Symphonic Strings.
The library features 68 string players recorded in the Teldex Scoring Stage, employing multiple microphone positions in a traditional seating arrangement. What I like about the Berlin Symphonic series is how cohesive it sounds when used with the rest of their products.
The library boasts well-programmed legato modes, multiple dynamic ranges, and articulations. Furthermore, you can turn off the unwanted dynamic ranges for any articulation in the proprietary SINE Player plugin, which helps you save RAM.
Key Features:
- Legato Modes
The library features three kinds of legato: melodic, pattern, and rapid. Melodic legato lets you play graceful melodies with transitions between notes and vibrato, pattern legato allows you to play ostinato parts with three round-robin samples, and rapid legato is for string runs. And best of all, you can combine any legato type with any sound patch.
- Dynamic Ranges
Almost every articulation features four dynamic layers: pp, mp, f, ff. However, the trills, pizzicato, and bass tremolos only feature pp, mf, and ff dynamics. You can cross-fade between the layers using expression to create smooth changes.
- Seven Positions
The library features seven microphone positions for each instrument section, and you can control the level of each one for mixing. The positions include Spot 1, Spot 2, Decca Tree, A-B, Leader, Outrigger, and Surround.
The two Spot mic positions are almost alternatives for each other as the main mic, the Leader is a single spot mic in front of the section leader, and the rest are mostly for adding width and space to your mix. If you are after the classical sound, use a blend of Spot 1 and the standard Decca Tree positions.
- Expression
The library comprises 12 articulations per instrument section, except for the basses. The contrabasses do not come with trills and only have a melodic legato. Overall, the articulations cover everything you could need, with the only noticeable missing articulations being harmonics and sul pont, which are handy for textural beddings, and portamento.
Compatibility:
The library is available for Windows 10 or higher and macOS 10.13 or higher, both 64-bit only. It comes in VST 2/3 and AU formats.
The 4 Best Free Strings Plugins 2025
1. Orchestral Tools – Layers
Layers is an excellent choice as a backing string ensemble or even underscoring.
Orchestral Tools is well known for its fabulous orchestral libraries, and Layers is their free, highly usable instrument plugin that features an entire orchestra along with individual instrument categories. You will find a symphony, woodwinds, brass, and a strings section, where the latter is what we’ll be focusing on.
In essence, Layers is designed to let you play backing ensembles as chord beds and also play melodies using the legato patches. So, I would recommend it if you make pop, rock, hip-hop, or any other commercial music, where you need string ensembles as backing tracks.
Key Features:
- Pre-Orchestrated
The library features two articulations: sustain and staccato. Each articulation features three pre-orchestrated chord types: major, minor, and sus4. And each articulation also features a Low Unison variety, which is the bass. Furthermore, the sound is full and excellent for use as pads.
- Mixing
Each section of the library features four microphone positions: A-B, Close, Surround, and Decca Tree. The second and latter are the main mics, whereas the rest add space and width. You can use them to adjust how intimate or massive your strings are.
- Legato
Orchestral Tools have some of the finest legato scriptings around, and Layers also features a sustained legato path. You can use it to play leading melodies across the entire ensemble or play harmonies for backing.
Compatibility:
The library is available for Windows 7 or higher and macOS 10.12 or higher, both 64-bit only. It comes in VST 2/3 and AU formats.
2. Orchestral Tools – SINEfactory: Helix
Helix is a simple string ensemble with a surprisingly rich, expressive sound.
The library’s ensemble features solo violins with violas, celli, and double basses. These strings come straight from the Berlin Series collection, so the recording is undeniably excellent and usable despite being free. The entire ensemble is laid out across the keyboard for quick performance.
Key Features:
- Articulations
The library features sustain and spiccato articulations. However, despite the limitations, the highly dynamic sound makes the library worthwhile. You can create convincing string ensemble parts that are fitting for scoring or general music production alike.
- Excellent Sound
As we’ve mentioned, Helix is taken from the Berlin series of orchestral instruments. The sound is deep and expressive, and I’d even call it “expensive.” Furthermore, after you subscribe to SINEfactory, you will gain access to several other libraries that sound just as good.
Compatibility:
The library is available for Windows 10 or higher and macOS 10.13 or higher, both 64-bit only. It comes in VST 2/3 and AU formats.
3. Spitfire Audio – LABS Strings
LABS Strings is a free ensemble string library with an outstanding sound.
Unlike the other LABS instruments recorded with peculiar playing styles, Strings is relatively standard and usable alone or for layering with other string libraries. It sounds like the library was recorded using close mics, but the large knob in the interface allows you to add reverb or tightness.
The reverb gives some much-needed space to the mix if you intend to use the library alone.
Key Features:
- Long and Short
The library features three articulations: Long, Ensemble, and Short. The long and ensemble are both sustains, but I preferred the ensemble one for writing melodies. And as you might have guessed, the short articulation is staccato that you could use to create ostinato patterns or add some embellishment to an arrangement.
- Expression
The library features multiple dynamic layers, and you can control it using your modulation wheel. Velocity does nothing, so you might as well set your keyboard to fixed velocity, and it’s a good thing – you can use the modulation to create dynamic legato pieces.
- The Big Knob
The knob lets you control reverb and tightness. Here, the reverb implies the rest of the mics, including a vintage special BBC AXB1, used to record the instruments. And tightness is a transient controller that makes the staccato even more biting. I would use it only for layering.
Compatibility:
The library is available for Windows 7 or higher and macOS 10.10 or higher, both 64-bit only. It comes in VST 2/3, AU, and AAX formats.
4. DSK – Strings
When you need something simple and almost retro, DSK will have you covered.
DSK is one of those developers you have most likely run into while getting started with music production. Their free plugins are famous for being decent, and DSK Strings is no exception. It features two layers, where you can load one of the four instruments: violin, viola, cello, and contrabass.
Furthermore, it also comes with multiple varieties (dynamics, solo vs. ensemble) per instrument and onboard mixing effects. Similarly, it features an octave feature that lets you create a richer sound quickly.
Key Features:
- Envelope
Each of the two layers features a volume envelope section. Since this strings plugin is dedicated as more of a backing ensemble, having an amp envelope makes sense. You can use it to make the strings sound more “pad-like.”
- Mixing
The plugin features three effects per layer: flanger, delay, and reverb. They are all dedicated to creating spaces in your mix, and the flanger is also useful to create synth-like sounds out of the box. Other than that, you can adjust the volume of each layer.
- Perform
DSK Strings features some buttons on the bottom right section of the interface to control the plugin’s performance. You can activate an envelope retrigger, mono mode, adjust the bend range and portamento time.
Compatibility:
The plugin is available for Windows XP or higher 32-bit only. It comes in VST 2 format.
Other Great Strings Plugins
1. Spitfire Audio – Hans Zimmer Strings
Sampling in collaboration with the film score composer Hans Zimmer, Spitfire Audio presents a new standard for cinematic strings libraries.
What sets Hans Zimmer Strings apart from regular strings plugins is its insane number of players and a massive range of articulations and expressions. 344 string players were recorded performing in the Lyndhurst Hall at London’s AIR Studios, where most of Spitfire Audio’s libraries are recorded.
The players were arranged in various sections of the hall and its galleries and recorded with multiple mics, giving you up to 26 mic positions to adjust while mixing. The result is a sound that you can only classify as epic and massive.
Key Features:
- Intuitive
Despite the huge amount of sound in the library, the plugin remains unbelievably intuitive, smooth, and easy to use, thanks to the design by UsTwo, a user experience agency. The interface features several faders and a large, customizable knob that allows you to assign reverb, vibrato, etc.
- Articulations
As promised, Spitfire Audio covers a large number of articulations per instrument section and mic position. You will find every standard articulation you’d expect and oddities like long col legno tratto, timed marcato, and the aggressive Bartok pizzicato. Note that several of these will require you to open a separate instance of the plugin.
- Multiple Mics
Depending on the ensemble section you have loaded in your plugin, you will find numerous microphone positions. They include your standard close mic and Decca Tree, up to 23 more, and an odd “Bottle” mic, which is a mic placed inside a water bottle. I must say it does sound interesting for the sake of sound design.
- Soundscape
Thanks to the unusual recording positions, you will find a deep sense of space in this library. While the close mics are relatively dry, once you add in other mic positions like the gallery one, you will soon find yourself washed in waves of wide reverb. And it really helps add to the epicness and scale of the library.
Compatibility:
The library is available for Windows 7 or higher 32-bit and 64-bit and macOS 10.10 or higher 64-bit. It comes in VST 2/3, AU, and AAX formats.
2. Spitfire Audio – Abbey Road One Legendary Low Strings
Impending doom, fearsome battlefields, deep suspense — nail each of them using the classic sound of Abbey Road Studio One.
Spitfire Audio Low Strings is precisely what it sounds like: a cello and bass section recorded in Studio One (not to be confused with the DAW software). The sound is imposing and undeniably epic. I would recommend its use in dark fantasy and horror music, or even in modern hip-hop if you are after a dark sound.
The plugin features a handful of articulations and plenty of mic positions to play with. Furthermore, its legato programming is excellent and sounds natural, and feels catered towards film scoring.
Key Features:
- Mixing
The plugin provides 10 microphone positions for you to mix and blend. Add more of the close mics, and you will find the low end getting aggressive, while a little bit of the room mic adds tasteful space. Furthermore, having this level of control ensures ease in mixing the sound of this instrument with your other libraries.
- Performance
There aren’t many articulations available in this plugin. It features staccato, spiccato, long, and epic legato. As you have probably guessed, the long notes are better suited for pad-like textures, whereas the epic legato presents a natural and graceful performance for melodic writing.
Compatibility:
The library is available for Windows 7 or higher 32-bit and 64-bit and macOS 10.10 or higher 64-bit. It comes in VST 2/3, AU, and AAX formats.
3. SONiVOX Orchestral Companion Strings
More Info & Price (Trial Available)
The strings plugin from the Orchestral Companion set is ideal for low-budget classical composition and even film scoring.
Orchestral Companion Strings features two violins, a viola, a cello, and a contrabass section with multiple articulations. There are no multiple microphone positions, but the sound is rather impressive. There are many presets for each section, and you can do some basic sound editing to better fit your strings to your project.
However, it’s not all praise for this one. I noticed that if you perform notes extremely fast, the plugin starts skipping notes. Similarly, the amp envelope release simply doesn’t work in the sustain patch, and contacting Sonivox or in music hasn’t resulted in any support. A workaround is to use reverb to fake a release for pad-like layering.
Key Features:
- Performance
Orchestral Companion Strings features five articulations: sustain, staccato, spiccato, pizzicato, and tremolo. You will find each articulation separately in the presets, along with one that features all of the articulations with key switches. Furthermore, it features up and down-bowing patches for most of the articulations. However, you cannot load multiple articulations and assign key switches yourself.
-
- Onboard Effects
The instrument features four built-in effects: reverb, chorus, delay, and EQ. While I wouldn’t say the reverb is highly usable, it comes in handy when you need some basic space for backing strings. The rest of the effects are moderately helpful, but you can turn each of them off if you want to.
- Modulators
The plugin features two envelope sections and three LFOs. You can control the volume and an assignable filter using the envelopes, whereas the LFOs let you control the volume, filter, and pitch. Automating the built-in filter along with the volume lets you quickly fake crescendos and decrescendos.
Compatibility:
The plugin is available for Windows 7 or higher 32-bit and 64-bit and macOS 10 or higher 64-bit. It comes in VST 2, AU, and AAX formats.
Conclusion
When selecting a strings plugin, make sure you choose the one that fits your workflow and music genre. For instance, a hip-hop producer wouldn’t need extreme detail, whereas a classical composer would. So, if you are a classical composer, I suggest checking out VSL Synchron and Berlin Symphonic Strings.
However, if you already own some libraries and are looking for samples that sound ideal for layering, check out Spitfire Hans Zimmer Strings (Lower section of the article).
If you make pop, hip-hop, rock, or other mainstream genres, check out Ujam STRIIIINGS for a super quick workflow, and the free instruments Orchestral Tools SINEfactory Helix and Spitfire LABS Strings are brilliant as backing ensembles.
And finally, if you are on a budget, I would highly recommend Sonivox Orchestral Companion Strings.
There are a few bugs like the sustain articulation release and skipping notes when playing extremely fast. Still, if you replace the problematic parts with free libraries on our list, you will find yourself equipped with a rather powerful tool.
