Harmonic Subtones logoEmotional Cello – never before could you play a virtual instrument at this level of expression.


Emotional Cello is a new kind of virtual instrument, created by Harmonic Subtones, a Munich based developer team, for Native Instrument's Kontakt 5 Player. Because of its powerful and yet exceptionally emotional sound, it unlocks previously unknown dimensions in the realms of sampling.

Emotional Cello is the perfect instrument for film-scoring, pop-production, song-writing, classic and modern avant-garde cello compositions. This unique virtual instrument shines by its impressive number of articulations, its direct and uncolored sound quality, unusual play techniques and innovative rebowing.

cello bridge banner

Emotional Cello was always recorded in a musical context to capture the natural bowing and the individual expressions of real instrumentalists. Thanks to intelligent scripting, 16 play-styles and true legato, this library offers immense versatile applications. Emotional Cello offers typical play-styles and articulations and also unusual techniques such as

  • sul ponticello legato and
  • flageolet legato,
  • morbid sustain,
  • ricochet and even
  • renaissance sounds.


Cello & Mic

Harmonic Subtones calls the underlying philosophy of the Emotional Cello project „Contextual Sampling“. In search for perfect tone and highest inspiration, various string instruments were recorded over a period of no less than four years, realising that nothing can match the natural vibrato with its artistic facets performed by skilled musicians. Although any sample that includes recorded vibrato has obvious conceptual drawbacks, the sound of the performance itself will be a lot more inspirational than adding artificial vibrato. Based upon this insight, Harmonic Subtones went to extract the recordings with topmost musicality to forge a brilliantly sounding instrument.
The result is a library of unmatched authenticity.

To achieve conclusive arrangements, Emotional Cello offers a multitude of articulations. This way, the several phrases, turns, variations, pickups and endings can be used as real autonomous phrasings without ever being repetitive. To properly match the various sounds and articulations to your musical context, respective key-switches with appropriate naming, like delicate fast, vivid or moderate were added.

In addition, Emotional Cello offers unusual and unconventional articulations, you will not find in most competitive products. For example:

  • the so called Spilegno, a harder edged Spiccato with bow-noise,
  • Power 5th Spiccato,
  • Plectrum Pizz,
  • Rota Spiccato
  • and a lot more.

Technical refinements were added, such as the rebowing-function which allows controlled directional change of the bow within a note using a key switch – highly useful for long sustains. Likewise, the vibrato-crossfade allows creating rhythmically perfect transitions from non-vibrato to vibrato-patches.

Emotional Cello Screen 1


Emotional Cello was recorded in the Mastermix Studio, Unterföhring/Germany. The instrument was carefully mic'ed in a wood-paneled room with high ceilings and highest possible wall distance. Microphone recordings were performed intentionally close using two Neumann models KM184 and U47, preserving a discreet portion of the room's excellent acoustics. At the same time, the close mic'ing technique easily allows external processing, e.g. to accomplish an overall ambience for the mix. Use the integrated convolution reverb of the Kontakt 5 Player or the pure unprocessed original sounds as needed.

Emotional Cello Screen 4


Emotional offers three true legato master-patches: Normal, Sulponticello and Harmonics. These contain about 80% of all recorded articulations, which are logically interconnected using advanced scripting. For example: A note being played at the beginning will sound perfectly natural because the chosen sample will also be the first note of the source recordings. The same goes for legato- and sustained notes: All samples originate from a corresponding context of the original recordings.
Each of the approximately 50 additional single-patches contains  a selected articulation. Choices range from simple sustain-patches to dynamic crossfades between four layers. These patches are useful for producers who prefer to spread articulations on different MIDI tracks instead of toggeling between them via key switches. To achieve highest authenticity and liveliness, the patches offer four round-robin-samples for long notes and up to eight for short notes.

Test Fazit

Emotional Cello überzeugt mich klanglich auf ganzer Linie. Neben ausgewogenem Charakter tönt es an den richtigen Stellen bissig, lebhaft oder sanft. Die wahre Stärke der Library liegt in der sorgfältigen Sample-Auswahl ohne störende Nebengeräusche, perfekter Intonation und sorgfältiger Programmierung. Die Ausstattung und innovativen Konzepte machen Emotional Cello zum exzellenten Soloinstrument für Filmmusik und Pop bis hin zur Klassik oder Moderne.

There are a quite few virtual cello instruments on the market but this one is an absolute winner. It is not just about sounding authentic, sounding like a real cello player, the thing about this library is that it sounds absolutely beautiful, or – as the name suggests – emotional.

Mit Emotional Cello ist es den Best-Service-Entwicklern gelungen, das emotionsgeladene Cello einzufangen und durch die aufwendige Samplingmethode ein intuitiv zu bedienendes, authentisch klingendes Kontakt-Instrument zu bilden. Einen echten Cellisten kann auch diese Library zwar nicht ersetzen, dennoch ist die Authentizität beeindruckend. Es ist vorstellbar, dass die Methode des „Contextual Samplings“ auch in Zukunft häufiger genutzt wird, um solche lebhaft klingenden Instrument-Librarys zu entwickeln. Wer eine authentisch klingende Cello-Library mit ausgereiften Möglichkeiten für Artikulation, Bogenwechsel und Vibrato per Key-Switch sein Eigen nennen möchte, erhält mit Emotional Cello ein Kontakt-Instrument der Spitzenklasse.

Best Service und Harmonic Subtones habe nicht zu viel versprochen: Emotional Cello schlägt ein neues Kapitel im Bereich der samplebasierten Streicher auf: Das Cello klingt warm, intim und voll. Die Methode des „Contextual Sampling“ wurde in akribischer Feinarbeit und mit viel musikalischem Einfühlungsvermögen umgesetzt und hat ein einzigartig lebendig klingendes Sample-Cello entstehen lassen.

Emotional Cello ist ein äusserst ausgefeiltes und fortgeschrittenes Kontakt-Instrument, es glänzt mit einer sehr umfangreichen Anzahl an Artikulationen und Klangfarben. Ein „echtes“ Cello ist ein ausdrucksstarkes Instrument und Emotional Cello fängt davon auf beeindruckende Weise einen großen Teil ein. Natürlich ist auch Heute die Technik noch längst nicht so weit, einen echten Cellisten durch ein Programm zu ersetzen, aber Emotional Cello reizt die Grenzen dessen, was aktuell möglich ist sehr weit aus.Dabei klingt es meist sehr natürlich und die Zuordnung von aus Phrasen gewonnenen Samples an ihre korrekte Position in einer neuen, MIDI-getriggerten Phrase scheint sich gelohnt zu haben. 

Wenn eine Solo Cello Stimme gefragt ist führt eine geschicke Abwechslung per Keyswitches Dank dem großen Pool an unterschiedlichen Artikulationen zu sehr lebendigen und abwechslungsreichen Melodielinien. Hier nimmt Emotional Cello einen Spitzenplatz in seiner Kategorie ein.

Die Single Patches verdeutlichen, was für eine Fleißarbeit dieses virtuelle Cello darstellt und steuern einige aussergewöhnliche Spielweisen bei, die man in vergleichbaren Instrumenten nicht findet.

Overall, Emotional Cello has some seriously expressive mojo. The secret sauce is in the brilliant scripting that they use to command the thousands of meticulously recorded samples in a way that allows a keyboard to intuitively control a solo cello expressively. Before I even read the manual I was able to play satisfying lines through natural variations in dynamics, playing style (legato vs. non-legato) and mod wheel. Once I learned about the keyswitches and hidden features, I just took it to the next level.

Take time to experiment and learn the different styles. I learned about a number that I hadn’t ever heard before. I’m inspired to use this for scoring work, and I have the confidence that I could write a totally passably realistic cello part if I needed to.

Die jahrelange Arbeit des Entwicklerteams von Harmonic Subtones hat sich gelohnt. Der Klang ist wirklich toll. Es ist die beste Cello Software, die ich bisher kennen gelernt habe. Trotz der vielen Artikulationen ist es gelungen, die Benutzeroberfläche einfach bedienbar zu halten. Einfach geil!

VI-Control logo

excerpt from  user comments

...The new benchmark for acoustic instrument sampling, as far as I’m concerned, and the first solo string library that is truly deserving of the tag ‘professional’. A sampled cello, in short, that I immediately want to write a little concerto for. That’s how inspiring it is. And its quality tells me it will work. ...

...Maybe the best sampled instrument I've ever heard, and if the ease of use is what it appears to be, the bar has just been raised in a dramatic way...

...Wow. Now that's what a cello should sound like....

...this is by far the most detailed sample library I've ever dealt with...

...What an amazing library!...

...It seems like it's finally what some of us were waiting for all of this time....

...This is hands down the most convincing solo string library every released!...

Several patches sound like more than one person playing and there is no way to change it. There needs to be a way to control vibrato speed and intensity. Tone of instrument is fairly good Key switches cannot be changed- they should be. Interface is very nice

EMOTIONAL CELLO has become a go to sample set in my film score and concert music mock ups.  One of the trickiest part of my workflow, is conveying to film makers just how beautiful solo strings can be in a film score.   This instrument, with it’s many articulations and sheer sonic beauty and easy playbility is a godsend!

Solo String instruments are among the most difficult instruments to sample. I have been struggling with them for many years and gone through many commercially available products, with very little satisfaction. But now there is relief: Emotional Cello is the most detailed, thorough, well-scripted and beautiful sounding virtual instrument by a long margin.The sheer number of articulations is staggering! This is fast becoming a staple in my library.

I buy a ton of libraries each year as a working film composer – this is the best since BST.   Excellent.   When will you release the solo ‘emotional’ violin library?   Thanks again for your hard work on this.
