The Best (Free & Paid) Orchestral [Kontakt Instrument] [2025]

Orchestration is the arrangement of a piece of music for performance by a band, but what are they performing? They perform a different family of an instrument in a unified way, and this is where orchestral is abstracted, it is a collection of a different family of instruments, e.g a bowed string instrument (violin, double bass, etc), percussion instrument (bass drum, snare, cymbal, hats), brass instrument (trumpet, horn), and the likes.

So, in this guide, I'll review the best free and paid recommended orchestral libraries for the Kontakt instrument, some include multiple families of an instrument, while others are just a single instrument, starting with...

Orchestral Kontakt Library (Paid)

Note: These are the current prices as of the time of writing this review, so, it might change.

Another Note: If you have the thought about buying fancy libraries in the hope that they would make your music sound cool, you are joking. Learn how to compose good tunes before investing a dime, how? Use the free ones first (use the table of content above), and then come back to the paid ones for advance realism. This advice is geared towards beginners!

1.) Heavyocity Forzo Modern Brass ($554.00)

The first one on our list is Forzo Modern Brass by Heavyocity, and looking at the price, it's in a higher range, which might not be worth it for everyone, here are a couple of reasons you might want to opt for Forzo:

Forzo has been polished and recorded by the award-winning composer - Jason Graves, and A-list Hollywood Film Score Engineer Satoshi Mark Noguchi, which in turn creates a high-resounding orchestration in whatever niche you are opting for, be it film scoring, or just in your music tracks.

It isn't a mere orchestral library, it is a collection of 12 french horns, four trumpets, eight trombones (tenor, bass, & contrabass), and two tubas that deliver 25 GB of sheer brass power straight into the hands of the cinematic composer. Looking at the amount of work and the flexibility Forzo provides to record a stunning composition, it is well worth the price. Did I mention it features articulation? well, now you know, Forzo creative articulations give you further options to harness the power of the library.

The team at Heavyocity traveled across the country to record in a room where Hollywood’s finest films were scored, which they are now sharing with you to simulate the same environments in your tracks and or scoring, enjoy.

However, you might not want to use an extensive orchestral library, so, you might want to check other simple ones below.

3.) Heavyocity Novo Modern Strings ($549.00)

Another one by Heavyocity, this time they capture a modern string. Novo is packed with over 38GB of fully-customizable sound-designed string samples and enables you to tweak, process, sequence, and create an imaginable string composition.

Recorded at the famous Eastwood Scoring Stage at Warner Bros. Studios, which you can guess, it is not only a well-researched string instrument, but also deeply sampled for used in hybrid film, game, and television scoring. Simply put, this is one of the best cinematic strings instruments and if you know what you are doing, you would absolutely enjoy Novo Modern Strings.

Again, it is pretty expensive and it is costly for several reasons:

It not only delivers a sought-after string sound of famed composers like Hans Zimmer and Danny Elfman, but also features orchestral violin, viola, cello, and bass ensembles. You also get an auto down-and-up bowing for the most natural-sounding staccato and spiccato string performances you’ve ever heard. With close, room, and hall mic positions and a core set of key articulations.

Other interesting features that can create a vast possibility of string customization are the CYCLE and Macro control.

The Cycle is a brand-new dynamic playback engine that comes built-in with a set of controls that can quickly create rhythmic pulses, swells, stutters, and glitch effects, as well as effectual granular-style pads for ambient drones and textures.

and the...

Macro control act as the front and center control knob for the String Designer and Loop designer, whether you are planning to control multiple parameters across each channel such as volume, pan, envelope, EQ, and the like, using the macro control gives you the option to do that and on top of that, you can program swells, stutters, and sequenced effects for subtly evolving timbres or frenetic, aggressive modulation.

Each preset comes with a unique set of MACRO knob assignments, allowing you to instantly alter each sound to your specific needs.

and

one of my favorites is the...

LOOP Designer is packed with over 400 loops across three individual channels, you can cue-build, sketch, and, craft complex rhythms, multi-layered motifs, and lots of stuff. If you are looking for instant inspiration for your cinematic composition, you can always seek the help of the Loop Designer.

4.) Viola da Gamba ($97.38)

Unlike Novo, which is expensive and to be honest, most newbies wouldn't be able to afford that kinda range. But, it depends on what features and style of composition you are going for. This is where Viola da Gamba comes in, it is an old orchestra string instrument with 6 nylon sides and a range from C2 to C5. Its sound is rough and coarse - a wonderful addition to classical strings.

What I love about this library, is the simplicity and a clean GUI. It is also inexpensive compared to Novo. This is a great alternative to conventional orchestral string instruments.

Features:

• An exciting mix of microphones: The velvety sound of the Schoeps mics, Neumann U87 as well as Coles 4038 ribbon
• Six articulations: Beside arco, pizzicato, staccato, and spiccato, there are also unconventional articulations like arco-fragile, textures, and Xylo-mallet-hits
• An extensive number of round robins: Up to 16 with up to four dynamic layer
• The ability to play different amounts of instruments: All articulations can be played either as solo Viola da Gamba or as an ensemble trio with 3 instruments
• Additional FX: Delay, chorus, amped and drive
• Nine reverb types: Besides several different sizes you get special types such as an infinite and deep valley.

System Requirements:

• Approx. 0.6 GB of compressed data
• Kontakt 5.6.8 Full version is required

5.) Grand Harp ($70.33)

Grand Harp is well suited for classical music, and that is not to say, you can't blend it to whatever composition you are making, even if it is outside classical music, it all comes down to creativity. Cinematique Instruments focuses on capturing the notes in a very realistic and organic way and recorded the Grand Harp with several big condensers around the instrument. All main articulations are provided in four times round robins and up to 5 velocity layers, recorded in stereo 24 Bit. Only the Harmonics articulation was recorded in one round-robin.

You would also find six articulations in one patch, this way, you can easily and quickly change the articulation, and on top of that, you have an option to use reverb and sustain control sliders as well as a tiny but powerful arpeggio with separate voicing options and a very useful glissando mode. Lastly, you also get to use the auto-velocity button which sets the note length automatically. This is extremely handsome.

Video Walkthrough:

Features:

• One complex Grand Harp instrument
• 6 articulations
• Six presets and snapshots
• approximately 1000 Samples
• 1.3 GB of compressed data

System Requirements:

• Kontakt 5.6 full version is required to run this software

6.) Hyperion Strings Micro ($32.83)

Hyperion Strings Micro is one the most inexpensive string library on this page, it is suited for songwriters and music producers just getting into orchestral writing, as well as seasoned composers wanting new colors in their orchestral palette.

This robust string library is recorded at the historic Studio A at Fantasy Studios in Berkeley, CA, coupled with plenty of spatialization, environment simulation, and positioning controls and options to let you dial in the sound and character you need. While I personally use Hyperion for EDM kinda style, it is also perfect for rock, pop, to fully orchestral compositions.

If you care about a highly polished and configurable GUI, then I would recommend you go for this one, you can also watch the video walkthrough to get the feel of the refined and simple to use interface.

You would find various kinds of combined ensembles preset such as 8 Violins, 6 Violas, 5 Cellos, and 4 Double Basses. You would also get a handful of articulations for each section, e.g a multi-dynamic sustains both with and without natural vibrato, staccatos, spiccatos, and pizzicatos, as well as two basic dynamic expressions: long crescendos and decrescendos.

8.) Solino String Proto Ensemble ($8.00)

The cheapest of all! Solino String Proto Ensemble is a recreation of an imaginary EMINENT SOLINA STRING ENSEMBLE 'PROTOTYPE', which is sampled from the original MARK1 version. What I love about this version is that, you can configure the ultimate string synth, with as many as possible combinations of any of the 6 instruments as your system can handle, the more you go, the higher the CPU resources are used.

Sampled through vintage valves and transformers - no tape was used to preserve the purity of the wave - a taped version may well surface one day as a free upgrade.

Featuring customizable 'EQ MODULATION' EFFECT plus 2 PHASERS - allowing a different variety of ensemble with a wide range of movement, for complex and evolving synthesized orchestral sounds.
