Synth arpeggios are popular in many different genres, including synth pop, trance and synthwave. While you can create arpeggios manually, they’re typically created by using an arpeggiator. But where do you get one of those?
Many synthsand sequencers, as well as many modern DAWs, have built-in arpeggiator effects.If you’re not happy with these or your synth or DAW doesn’t come with an arpfeature, this page is for you. In the following list, I’m collecting the bestfree arpeggiator VST and AU plugins available today.
Freeloopsdownload website offers 1,000s of Royalty-Free Loops, Samples and Sounds Sets for Vst Plugins, it's a business of selling download able Products. It is intended for Musicians, Music. Arto Vaaralahas releasedKirnu – a free MIDI arpeggiator VST plugin for Windows.
Note: The plugins on this page do not create any sound on their own – you will need a sound source (for example a synth plugin like Serum or Massive) to hear anything.
The (maybe) ‘best arpeggiator plugin on the market’ named Kirnu 1 is a great and well known freeware plugin to give your creativity a boost. It's a very handy tool for e.g. Creating basslines or synth riffs in a snap. Reasons for using Kirnu instead of a plugin-internal arpeggiator are numerous.
How to usean arpeggiator in your DAW
Before weget to the list, here’s something a lot of new producers struggle with:
How do you usean arpeggiator plugin in your DAW?
While it’s hard to give a general answer, in most DAWs you will have to find a way to insert your arpeggiator plugin into the signal chain before your synth (or other instrument). Arpeggiators are not audio effects like reverbs or compressors, they are MIDI effects and should affect the MIDI data before it arrives at your synth. If you put an arpeggiator after a synth in the effect chain, you will typically not hear an effect at all! If you’re not sure how to add MIDI effects to your DAW, a look into the manual or a Google/YouTube search should help.
The Best Free Arpeggiator Plugins – A Collection
Arpimedes
Format: VST, 32 bit
OS: Windows
Audio examples:
You want to get the traditional arp sound but don’t want to spend a lot of time tweaking settings? Then you should check out Arpimedes by Tobybear. While it is the simplest arpeggiator VST on this list, it is also easiest to use. Set the speed, the number of steps (eight is the maximum), the number of octaves and the mode (up, down, up-down, down-up, as played, random) and you’re set!
This plugin is a good starting point when you’re new to arps but will probably not be sufficient if you need a little more control over your arp sound. As this one is an older release, it’s only available for Windows and runs in 32 bit.
Arpimedes is part of the Tobybear MIDIBag, which you can download here.
RandARP
Format: VST2, 32 bit + 64 bit
OS: Windows
Audio examples:
The cleanly designed RandArp is a VST plugin by CodeFN42. After choosing rate, note order and octave order, you have the possibility to play with certain settings that can then be randomized to your liking. These include number of octaves, velocity, gate, shift and swing. You can also choose the percentage of the note probability – this refers to how likely it is that a note is generated. Setting this below 100% means that more notes will randomly be skipped.
All in all, it should be noted that RandARP focuses (as the name suggests) almost completely on randomization features. There is no step sequencer where you can draw in notes and there is no feature to transpose notes (you’ll have to do that via MIDI), for example. So, if you want to design your arp sequences step by step, this will not be the right VST plugin for you. However, if you’re looking for an arpeggiator that helps you create ever-changing sequences, you definitely should check RandArp out.
RandARP canbe scaled up to 200% and comes with different skins for optimal usability. Althoughthe plugin is mostly self-explanatory, the download folder contains a 25-pagemanual that goes into detail on every feature and setting – perfect for anyone whowants to know how to get the most out of this free arpeggiator plugin.
You can download RandArp on the CodeFN42 website.
BlueARP VST
Format: VST, AU, 32 bit + 64 bit
OS: Windows, Mac
Audio examples:
You want to have maximum control over your arp sequences? Then you should try out BlueARP VST by Oleg Mikheev (also known as Graywolf). When I first opened this plugin, I was a little overwhelmed by all the settings and boxes. However, after playing around with it a bit and watching the following video by howtomakeemusic, I found it’s actually quite easy to use:
Besides atypical arp engine where you can control settings such as gate time, swing andnumber of steps, there is also a detailed step sequencer that gives you theoption to change velocity, step type and transpose the note (octave orsemitone). Step type includes normal, off, rest and tie. I particularly likethe tie feature, which creates a gliding effect between steps.
If you wantto play chords, you have the option of playing all the notes of the chord atthe same time or you can choose exactly when each note of the chord will beplayed.
Additionally,BlueARP has countless advanced features, like setting a range for filtering outinput notes or forcing the arpeggiated notes to a particular scale. If you usearp sequences a lot in your music, BlueARP will give you plenty of features to getthe exact sound you’re looking for. You can find more information about thedifferent features in the manual that’s included in the download files.
BlueARP can be downloaded on Graywolf’s website.

Best Free Vst Synthesizer
BeforeBlueARP appeared on the radar, Kirnu by Arto Vaarala was pretty much the numberone recommendation when it came to free arpeggiator plugins. Like BlueARP,Kirnu boasts a powerful step sequencer which can help you modulate settingslike note length, gate time, accent, transposition and shift.
Arpeggiator Software
Of course,you also have control over the rate, note type (normal, dotted, triplet), sortorder (when you’re playing multiple notes) and octaves. You can even choosefrom a long list of scales (including modes) if you’d like your arp sequences tostick to a certain scale.
Despite itscompact design, Kirnu is a powerful arpeggiator that can do a lot of funthings. Here are some examples from the developer:
I found Kirnu a little confusing in the beginning because not all of its features are self-explanatory. The download files don’t include a manual either – luckily, I found it on the developer’s website. After reading more about its many features, I found it much easier to create interesting sequences with it.
Note: Kirnu isn’t the same as Kirnu Cream, which is its commercial successor (if you’re interested in the paid version, please be aware that some stability and compatibility issues have been reported lately).
