Top Arpeggiator VST Plugins

Cthulhu by Xfer Records

Demo & Price

Cthulhu by Xfer Records

Cthulhu comes from the same maker of Serum, that beast of a synth. Likewise, “One Note Becomes Many” is the intriguing tagline that greets you at Cthulhu’s product page, and it does provide an accurate description of the capabilities of this unique plug-in. Is it an arpeggiator, an instrument, or an audio processor? Like the best arpeggiators, Cthulhu is all that and more.

What Cthulhu primarily does is transform inputted chords in many interesting ways. A versatile and easy to use tool, it encourages the creation of chord progressions and musical motifs that you wouldn’t have come up with otherwise.

Specs and useful features

Although Cthulhu does a great job as an arpeggiator, it is first and foremost a chord recorder/player. This function enables you to come up with plenty of interesting chord variations by pressing single keys on your keyboard. You can play chords right into the plug-in or import chords and progressions in MIDI format.

Cthulhu is equally capable as an arpeggiator, enabling you to transform notes and chords that you input into different rhythmic variations. With no less than eight tabs in the step sequencer, you have ample options for reshaping incoming notes. Even single note lines can result in complex and uniquely memorable riffs.

User impressions

You don’t a lot of musical knowledge to come up with complex and musically interesting motifs with Cthulhu. The chord memorization feature alone is well worth the price tag, and having a very capable arp onboard makes it an even better deal.

Literally dozens of interesting variations can spring forth from even the most basic note sequences. Whether as an idea generator or a way to reinvent tired, old melodic motifs, Cthulhu has the power to consistently surprise.

Bottom-line

A chord generator and arp rolled into one, Cthulhu is a powerful creative tool no matter how you look at it. If your creative well has run dry and you need a source of inspiration, this plug-in definitely gets the juices flowing.

Kirnu Cream by Arto Vaarala

Demo & Price

Kirnu Cream by Arto Vaarala

Kirnu Cream took the MIDI world by storm when it was released in 2013. The hype and speculation had been building up to a fever pitch for months before then, and the official release proved to be everything that everyone had hoped for and then some. Cascading arpeggios, sequenced patterns, and ear-catching chord memory progression–all these issued forth from the revolutionary plug-in, and there were many options for modulating the results as well.

Cream today remains largely unchanged from its initial version, which is a testament to its design and functional excellence. Whether used for arpeggiators, lead and bass lines, and even beats, Kirnu Cream is pretty much peerless.

Specs and useful features

Cream has several features that make it as suitable as a live instrument as a studio tool. The arpeggiator is what most people will probably be drawn to. But it also has one of the most powerful pattern sequencers around, with excellent chord memory features added to the mix. Pattern data can be selected and manipulated freely, with four tracks and loopable pattern controls. These features give the plug-in a great deal of flexibility for reimagining melodies and musical phrases.

Amazingly, Cream is very easy to learn and put into use. You didn’t have to dig too deeply into its inner workings to come up with cool motifs, although there is considerable power under the hood for more in-depth tweaking.

User impressions

The many opportunities for direct interaction are what most users appreciate the most about Cream. It goes beyond the capabilities of most arpeggiators and pattern sequencers, producing musical and creative results with very little effort. Many users especially like the “arpeggio on note count” feature, which keeps the arpeggiator from starting up until a specific number of notes are played. This feature makes it possible to combine standard melody lines with arps in a musical manner.

Bottom-line

With so much power onboard, you would expect Cream to be difficult to use. While you will have to do a bit of fiddling around to unlock its full potential, this never gets in the way of its sheer power and capability.

Thesys by Sugar Bytes

Demo & Price

Thesys by Sugar Bytes

Sugar Bytes is known for its plug-ins that serve as creative instruments and unique audio and MIDI processors. Thesys is a prime example, covering many of the company’s strengths in an intriguing step sequencer that is also a pretty kick-ass arpeggiator.

Thesys utilizes the venerable–and still-popular–step-programming paradigm in enabling you to manipulate your music in various interesting ways. Whether for heading off into uncharted musical territory or simply breathing new life into tired, old material, Thesys provides a direct path to creative musical expression.

Specs and useful features

Unlike other plug-ins that lock you into a specific way of working, Thesys lets you work the way you want to work. You could paint in sequences with your mouse, which is a fast and intuitive way of working. If you prefer a more traditional approach, you could input notes from a MIDI keyboard. There is a built-in synthesizer for this purpose, letting you hear inputted notes and the resulting sequence without having to patch in a third-party synth plug-in.

The Randomizer is an especially useful feature, helping you avoid the predictability that often results from step-sequencers and arpeggiators. With this feature, you can come up with interesting variations of your melodic material or head off into wild and wonderful new directions.

The Velocity and Gate Sequencer sections are where you will likely do most of your tweaking. These sections let you finesse riffs and arpeggios into impressive musical phrases without a lot of fiddling around.

User impressions

Thesys delivers far more capabilities than your average arpeggiator plug-in. Users found it to be just as useful live as in a studio setting. This is one plug-in that cranks out more than what you put in, and many users find it a sheer joy for livening up drab MIDI passages.

Bottom-line

Thesys is more than just an arpeggiator or a step sequencer. It is practically a full-blown MIDI workstation, and its sheer power and flexibility will definitely win you over.

Consequence by Sugar Bytes

Demo & Price

Consequence by Sugar Bytes

Consequence is Sugar Bytes’ simpler offering in the arpeggiator category, but it is still pretty capable at transforming inputted notes in interesting new ways. It creates note sequences based on chords that you play in, with numerous options for interpreting the incoming data.

You can load up to three instruments into Consequence, each of which has its own envelope. You can play these instruments via the onboard 32-step sequencer and create very complex rhythms and textures pretty easily. There is even a multi-fx unit onboard for adding extra spice to your creations, and a four-on-the-floor kick drum pattern that helps you keep your grooves locked tight.

Specs and useful features

The chord sequencer is where most of the action takes place. Here, you could store up to 16 chord “snapshots”, and trigger them in any combination you please. The results are never static, with five sequencers enabling you to control various aspects of the groove. There is also a comprehensive modulation section that provides even more options for controlling the three synthesizer parts, the filter, and the FX unit.

As an arpeggiator, Consequence is about as versatile as they come. You can set each of the sequencer steps to “Arp”, “Chord”, “Octave”, or “Tie”, enabling you to go well beyond the capabilities of most arpeggiators. You can even control the play direction in various ways, which lets you create pretty impressive melodies from even the most basic motifs.

User impressions

Consequence strikes many users as a fun and inspirational alternative to most standard arpeggiators. It is especially appealing to those looking for a fresh and creative approach to coming up with melodic ideas. For many users, Consequence has proven value as a songwriting and production tool.

Bottom-line

Like most Sugar Bytes plug-ins, Consequence provides a unique way of working with source material. Even if you already have a well-spec’d arpeggiator in your arsenal, Consequence is still worth adding to the pile for its unique workflow.

Bonus Mention: Numerology 4 Pro by Five12

Info & Price

Numerology 4 Pro by Five12

Numerology is something of a dark horse in the music production world, attracting an almost fanatical army of devotees. But it offers a totally different approach to idea generation, programming, and music production.

You could certainly use Numerology merely as an arpeggiator if you wish, even at this comparatively basic task. But its features makes it more of a complete music production solution than a mere arpeggiator plug-in.

Specs and useful features

Numerology is essentially a modular system, providing several options for sequencing audio, MIDI, and even control voltage (CV) signals. The matrix sequencer is your ticket to arpeggios, although you could certainly use it for more subtly melodic material if that’s what you need.

One of the best things about Numerology is that you can modulate almost any parameter. Like an extremely well-spec’d synthesizer, you can route anything to almost anything else, in this case to compositional parameters.

Bottom-line

Numerology is a beast of a plugin. Perhaps it is a bit unfair to lump it in with ‘mere’ arpeggiator plug-ins, but it does such a great job at that role that we simply had to add it to the lineup.


About Arpeggiator VSTs

An arpeggiator is a feature found on many synthesizers, vintage and modern, hardware and software. Often referred to simply as an “arp”, it lets you play a string of notes via a single key press or a single played chord. Even when playing a relatively simple phrase, arpeggiators can produce complex and impressive melodies and repeating motifs.

To learn more about what an arpeggio is, check out this Wikipedia entry.

Arpeggiators typically produce characteristic repetitive motifs that serve as the backbone for countless synth-based tracks. Used on such classic rock tracks as The Who’s “Baba O’Riley” and Pink Floyd’s “On the Run”, it is also the most recognizable element in Donna Summer’s seminal “I Feel Love”.

In its simplest iteration, arpeggiators simply play back the individual notes of a chord in sequence. In older synths, arpeggiators provided the option to play the note sequence from high to low, low to high, and little else. Many modern arpeggiators provide many more options for setting play direction, note length, and more. With some of the arpeggiator plug-ins reviewed above–and some advanced arpeggiators on hardware synths–the results can be far removed from the typical robotic lines of a primitive arpeggiator.

All arpeggiators are able to play back the notes in a held chord. But more advanced arpeggiators can store note patterns, and even chords, providing you with even more options to come up with fresh and inventive parts. Some even allow for layering of different arpeggio patterns, polyrhythms, and random triggering. When you add the capability to modulate the output in many different ways, there is no reason why arpeggiators should simply be relegated to churning out basic, repeating lines.

At the very least, you will want an arpeggiator that gives you a few different options for playing back notes. Extensive modulation options are also good to have, as is the ability to send the note data out as MIDI.
