Here’s a quick list about the best free arpeggiator VST plugins.
Note: most free arpeggiation plugins are mostly available for Windows PCs, while only a handful of them work on Mac, or even Linux.
However, I will also include 3 premium ones which are absolutely amazing that work on both Windows and Mac without any problems!
Let’s get started with my Nr.1 recommendation, which is;
Kirnu by Arto Vaarala (Windows, Mac)
Kirnu is a VST MIDI arpeggiator plugin that could also be considered a step sequencer, and it is designed with real-time tweaking and usability in mind.
It’s not the easiest plugin to use, but once you get the hang of it, you’ll love it, and it comes with all the features one would expect from a plugin like this.
If you’re looking for an even more advanced version of Kirnu, then check out it’s updated version “Cream“.
Note: Cream is not free, but for $35 it’s definitely considered a budget option.
You can download Kirnu here.

BlueARP by Oleg Mikheev (Windows, Mac)
BlueARP is a MIDI Arpeggiator plugin with a pattern sequencer style, designed for electronic music genres.
It is based on hardware groove boxes and arpeggiators like Korg Electribes, Novation Nova, etc.
BlueARP can also be characterized as: a pattern arpeggiator, step sequencer style arpeggiator, arpeggiator with pattern input.

Hypercyclic by Mucoder (Windows, Mac Linux)
Hypercyclic is an LFO-driven MIDI arpeggiator as well as a gate effect and step sequencer.
The main use for hypercyclic is to generate midi that can be recorded and/or sent to other plugins.
However, it also features a simple built-in synth for testing purposes.
You can use two tempo-synced LFOs to modulate various parameters for creating interesting rhythmic effects and chord variations
A unique feature is the possibility to modulate the sequencer step size itself, which is useful for creating glitchy stuttering effects.
Another thing you can use is a groove function for playing slightly off the beat.
The groove parameters can also be modulated over time by the LFOs, adding to the rhythmic variation.
You can download Hypercyclic here.

RandARP by CodeFN42 (Windows Only)
RandARP is an arpeggiator plugin with many randomization features, allowing incoming notes or chords to be manipulated in various ways.
All standard arpeggiator parameters like number of octaves, note length and note order are included…
But the plugin also offers complete randomization of the velocity, gate, shift and swing parameters.
In addition, you can specify a note probability and randomize the note order, the octave order, and the number of octaves.
All the randomization features allow you to create more interesting and unpredictable arpeggiated sequences.
You can download RandARP here.
Podolski by U-He (Windows, Mac, Linux)
Podolski is a free and straightforward CPU-efficient virtual analogue synthesizer.
It features one oscillator, one filter, one envelope and an arpeggiator/sequencer section that comes packed with features.
Overall, it might take you some time to learn how to operate this plugin, but once you do, you’ll love it!

Arppe2600vs by Glen Stegner (Windows Only)
Arppe2600va is a great softsynth that features a multitude of Frequency Modulation options which enable it to create some truly awesome sound effects:
PWM, Sample & Hold, virtual Spring Reverb, Ring Modulation, and a dedicated Noise Generator are all there!
Also, there is Oscillator Sync and Filter Color.
Arppe2600va is completely patchable via a designed Mod Matrix!
You can have up to 12 patch routings with a very user-friendly drop-down menu interface, instead of messy virtual patch cables cluttering up the screen.
It can be both used as a standalone synth or loaded in any DAW.

Arpimedes By Tobybear Productions (Windows Only)
If you want an insanely simple arp sound without having to deal with an overloaded and confusing interface, then Arpimedes is definitely for you.
It’s the easiest arpeggiator to learn on this list, and you can only set the speed, number of steps, number of octaves, and the mode.
That’s basically it!
If you have no prior experience with arpeggiators, then definitely give Arpimedes a try!
You can download Arpimedes here.
Note: It’s part of the MIDIBag bundle, which you need to download in order to get Arpimedes.

It is a Duophonic synth with 2 sync VCO (6 waveforms), 1 noise generator, Sample and Hold, 1 sine or square wave LFO, 2 filters (LP and HP), 1 VCA and 2 envelopes (1 ADSR and 1 AR), portamento and so on.
Everything is editable, tweakable and that gives many possibilities.

Tonus by KBplugs (Windows Only)
Tonus is an emulation of the ARP 2600.
This emulation is only inspired by the circuitry of the real unit, but it’s not really trying to emulate it and sound identical, but rather have its own personality.
There are no presets, just like on the real arp.

Move the joystick arund and play the virtual keybord or MIDI.

Premium Arpeggiator Plugins
After you’ve tried some of the free ones, I think that it’s a good idea to move over to some arpeggiators that are actually more powerful.
In most cases they will cost you a bit of money, but most of them are extremely affordable.
Here are three which I consider to be excellent!
Cthulhu by Xfer Records (Windows, Mac)
Cthulhu is a Chord and an arpeggiator plugin.
The chord module allows you to play one note and Cthulhu will automatically create chords off of that one note.
This is great for when you’re trying to compose a song but can’t come up with new ideas.
You can press any key and Cthulhu will automatically play a chord that fits perfectly within that scale.
It comes with loads of chord presets, and it also allows you to create your own chord presets and save them.
If you import MIDI or record chords straight in, Cthulhu is able to analyze the chords you play and allow for various sorting options like;
Circle of 5ths, Chromatic, low note, etc…
Allowing for easy access over your chords.
The other half of Cthulhu is a unique pattern-based arpeggiator, allowing incoming notes or chords to be manipulated in various rhythmic ways.
For instance, starting on the lowest note and ending up on the highest (when it runs out of notes, it starts back on the first one).
You can choose whichever pattern you like, sequence them in no time and that’s it… you have the basic structure of a song.
Additionally you can get the ADSR bundle which comes with over 140 chord presets and 50 arpeggiation presets which are quite good.
This Plugin is great, really fun and easy to use…
The only down side is that it´s not free (It costs $39), and the ADSR bundle also costs a bit of money ($24).
You can get Cthulhu here.

ARPG8R by Pentacom (Windows, Mac)
ARPG8R is an amazingly simple, yet powerful MIDI arpeggiator.
It’s super straightforward and does exactly what you hope it will do.
Not only that but it takes any VST and transforms it into a fully programmable sequence.
It’s much easier to use than most built-in VSTi arps, and this turns any arp-less synth into an instant rhythmic powerhouse!
If used right, this arpeggiator has the power to enhance any kind of music that has a beat.
It’s not limited to electro genres only… it can actually be used on many genres.
You can also simply engage and adjust the shuffle feature if you want a more natural feel.
Additionally, they have pretty good online tutorials on YouTube, which is always nice.
Here’s a link to one.

Cream by Kirnu Interactive (Windows, Mac)
Kirnu Cream is a very powerful MIDI performer VST/AU/LPX MIDI FX plugin for Windows and Mac.
With Cream it’s very easy to create catching lead parts, bouncing bass lines, swinging drums and lots of other cool stuff.
With simple and clever design, it has been made easy to learn and operate.
You can easily create cool performances by tweaking only couple of controls.

I also like Podolski and BlueArp, but Kirnu is the best one overall.
