Top 12 Randomizer Plugins 2023 Including FREE Plugins

Today we’ll take a look at the best randomizer-featured plugins available in 2023.

Since the 1940s, we’ve been using circuits to amplify our instruments, modulate our voices, and even create weird sounds with our keyboards. When the personal computer arrived, all these unique aspects were translated into algorithms or code lines that would influence how the software works.

One of the most amazing achievements of our modern technological society is undoubtedly artificial intelligence, found in a multitude of knowledge areas. It can be used to give poor chat support on your shopping website, but it can also bring smart tools to the music-making world.

One such tool is a randomizer: virtually, a configuration that randomizes any set of parameters as you wish. It can be very helpful to develop new loops, bring a natural human imperfection to virtual instruments, and even recreate faulty aspects of vintage studio gear.

Today we’ll take a look at a selection of plugins that feature a randomizer option in 2023, no matter which effect or sound crafting tool.

You can also utilize this “Infinity” mode to have Riffer randomize your idea after listening to your tack for a short period of time, saving you a bunch of working time.

Compatibility:

The plugin is available for macOS 10.12 or higher and Windows 7 or higher (32 and 64-bit). It comes in VST3 and AU plugin formats.

Summary:

There’s a certain limit to what technology can achieve, artistically speaking. Some producers may argue that it’s impossible for machines and clever AIs to create something deep and profound, and that’s probably true. But that doesn’t mean it can’t assist you, and Riffer proves that right.

The easy connectivity with basically any sort of MIDI device is welcoming to producers or musicians trying to register musical ideas, and the separate banks can spice things up with different voices and melody lines. But the best feature is the very well-designed random mode that can work perfectly alongside your current idea.

12. Sugar Bytes Turnado (Multi-FX With With Effective Randomization)

More Info & Price (Trial Available)

This plugin features a simple interface, but it has a ton of custom effects to experiment with.

Turnado is a very special plugin because of the endless possibilities one can achieve with it. This plugin is a multi-effects processor, with all of these effects distributed inside the interface in a somewhat polluted display. At first sight, it might seem a bit intimidating and confusing, but the controls are fairly simple to use.

As it’s very lightweight on your CPU, this can be perfect to use in a live performance or in a turbulent recording session, with many instances open at the same time. The effects combinations are almost infinite, ranging from subtle tweaks to more aggressive settings in each effect.

Key Features:

• • “Dictator” knob
    Turnado can be a remarkably flexible plugin both in the studio or on stage, with its operation reduced to a minimum of controls. If you’d like to keep it simple and gain some time, the “Dictator” fader will likely interest you: it allows you to control many knobs with only one slide. You may specify when and how much each knob should be turned in this section, automate all controls, and use MIDI to trigger them.
  • Route your signal
    If you want to route your signal via the effects, there are two possibilities: going through each one in order (from the banks “1” through “8”) or using the “Dynamic Signal Flow” mode, which sets the order for each effect to be enabled. Setting up the sequence of effects is a skill on its own, and the option to interchange effects by dragging one over another allows you to instantly hear how a different order affects the overall sound. This is also useful if you want a reverb to always be the final in a chain, despite if it’s active
  • Five controls in any effect
    The amount of control provided is astounding, with the option to modify five separate factors. The magic comes from the fact that each of these five knobs may be linked to the main-screen controls. Each slot features two LFOs and step sequencers, with an envelope follower that may be used to modulate with a bit of automation as well. Any impact parameter can be given one of these, so the possibilities are almost endless indeed.

Compatibility:

The plugin is available for macOS 10.12 or higher and Windows 7 or higher (32 and 64-bit). It comes in VST2, VST3, AAX, AU, and standalone plugin formats.

Summary:

If you’re in need of some cool effects and some fresh ways to organize them, this is the perfect plugin for you. The amount of options – like reverb, delay, stutter, ring modulator, vocoder, guitar amp, and many more – is incredible, but the main thing is how they can be connected to one another.

The routing and other similar controls (like the “Dictator” knob) can help you keep everything the way you like, prioritizing a fluid performance, either live or in the studio.

The 10 Best Multi-Effect Plugins (And 3 Best Free Plugins)

3 Best Free Randomizer Plugins 2023

1. Audiomodern Gatelab (FREE Creative Random/Gate Sequencer)

More Info & Download

A nice freeware option for a gate sequencer, with lots of creative and random controls.

Gatelab is a gate sequencer with a creative twist, as well as a volume modulation generator. It generates ever-evolving patterns and limitless rhythmic effects by randomizing a unique mix of controls and factors.

You can use this variety of music-making and sound-mangling capabilities to chop up any audio stream and come up with fresh, innovative ideas on the go. It may also transfer MIDI data to other plugins, allowing it to randomize settings and expand its controls even further.

Key Features:

• • Infinity mode
    The “Infinity” mode takes control of the sequence and develops a completely new pattern each time a new loop begins, allowing you to relax and let it do the work for you. You may also specify how many times it will repeat itself before generating a new one. If x2 is set, for example, each pattern will play twice until the mode re-generates a new pattern, and so on.
  • MIDI automation
    Gatelab has two MIDI channels that may be used to control various instruments or audio effects in your project, activated by pressing the “MIDI” knob. Going even further, in “Stereo” mode, MIDI Channel one and two correspond to the plugin’s two MIDI channels that can be used to convey MIDI data to another instrument or effect in your project.
  • Additional modes
    The number of modes that can be found within Gatelab reflects how useful this plugin is. The two volume modulation modes called “Flow” and “Gate” can instigate variable sequences regarding volume, whereas the three “Randomization” modes (“Settle,” “Normal,” and “Complex”) can generate new randomized filter sequences. Other modes, like “Density” and “Disintegration,” allow the plugin to split steps and create different rhythms and control a disintegration sequence based on the aforementioned “Infinity” mode, respectively.

Compatibility:

The plugin is available for macOS 10.12 or higher and Windows 7 or higher (64-bit only). It comes in VST, VST3, AAX, AU, iOS, and standalone plugin formats.

Summary:

This freeware is filled with nice tools that can add more energy and creativity to your loop or pattern. Gatelab was created by the same developers as Riffer (mentioned above), so you can expect quality in your loops and awesome results.

The number of modes dedicated to creating, randomizing, looping, or even disrupting every cycle is astonishing for a freebie, and the MIDI automation excels just like in any paid plugin, allowing even for external plugin control.

2. Surge Synth Team Stochas (Random MIDI Arranger)

More Info & Download

This probabilistic polyrhythmic sequencer plugin is an open-source option with many features.

Stochas is a ground-breaking new step sequencer with a one-of-a-kind randomization engine. It may be utilized to produce growing melodies, rich-sounding synth segments, unusual basslines, and even repetitive percussion patterns. Editing and inputting patterns is quick and straightforward, both in chord input and predetermined scales, so you can get some results even if you don’t know any music theory at all.

Key Features:

• • Groove and humanization
    When talking about grooves, Stochas has a very nice “Groove Editor” that can make it as easy as it gets. You can control the timing and playback of any steps, with the possibility to save them and use it in other sessions. The MIDI connections allow for these grooves to be exported as you wish, a perfect tool for live performances. You can also apply a basic swing into the steps, getting a more dynamic and organic approach to these patterns.
  • Randomized settings
    Sotchas’ major role is to supply unpredictability to the step sequencing process, albeit it may be utilized for simple step sequencing. You can make use of this randomization in every note (whether it should be played or not), between two or more notes (creating random drum patterns or melodic lines), in the timing in which each note is played, and finally to the velocity and length of said notes.

Compatibility:

The plugin is available for macOS 10.11 or higher and Windows 7 or higher (32 or 64-bit). It comes in VST3 and AU plugin formats.

Summary:

Incredibly full of features, Sotchas is one more great plugin from Surge Synth Team. It excels at randomizing sequences, patterns, melodies, scales, and anything in between, with many cool features in addition.

The randomized mode is provided by a great algorithm that can expand such unpredictability to creative and fun ways to mess around with. Its interface is cleaner than expected for a plugin like this, so it’s inviting and not so complicated to tweak around.

2 Bonuses:

1. SineVibes Rerun v2 (Self-Randomizing Repeater)

More Info & Price (Trial Available)

A simple design with a powerful capability to achieve nice patterns and loops.

Rerun is a plugin that provides a self-randomizing repeater effect. It continuously captures tiny chunks of input audio, replays them as many times as wanted, and then repeats the process. It randomizes the chunk size and number of repeats of the samples each time they transition to the next cycle of repetition and then engages or stops based on the probability parameter.

Key Features:

• • Probability mode
    Setting the “Probability” knob from 0% to 100% determines the probability for the slice repeater to be engaged for the next round of repeats. With the two parameter modes, “Sum” and “Gate,” you can also determine if the dry signal is muted or passed through when the repeater is not engaged.
  • Direction control
    Aside from the repeats, you can also choose how they will be played, directionally speaking. There are three modes (“Forward,” “Reverse,” and “Alternate”) that can be switched by clicking the knob. On the first one, all slices are played backward; on the second, the first slice is played back forwards, with the others in reverse; and, finally, the last one allows for the slices to be played in randomized forwards-reverse directions.
  • Randomized slices
    The “Size” and “Repeat” knobs control, respectively, the duration of one repeater slice and the number of slice repeats. Both at a minimum and maximum settings, each value is randomized in order to bring more naturality to each repetition. For example, the “Repeat” control allows for one to five repeat counts at the minimal setting and for six to 50 at the maximum.

Compatibility:

The plugin is available for macOS 10.9 or higher and Windows 8.1 or higher (64-bit only). It comes in VST3, AAX, and AU plugin formats.

Summary:

With this plugin, you can explore the slices of any sample you have in the best way possible, with infinite variations and unique patterns. The algorithm behind SineVibes’ ReRun 2 works perfectly with virtually any kind of sliced audio available. The parameters allow for different approaches, such as a reverse mode, and the randomized repetitions are a welcome addition to get your creativity flowing endlessly.

Conclusion

A randomizer is a welcome advancement to make your track stand out, no matter in which scenario. We have enough development to make it work even in live performances, as fluid as it could’ve been in our imagination.

Randomness should not be mistaken with impermanence, however: we, as producers, want to take advantage of this aspect in the most artistic way possible, as to always implement an upgrade to what we’re already doing.

This is where a randomizer option gets to shine. You can use it on your effect, loop, or instrument, maybe because you’re not feeling so creative or because you’re in need of a slight adjustment. What matters is that it can be an addition to your work.

If you’re looking for a sequencer, we’ve got quite a few big names on this list. Algonaut’s Atlas 2 is a very crafty tool that will assist you in every possible way when it comes to the house, techno, and UK garage music production.

Your ideas will never be the same with this awesome software, especially because the randomizer works brilliantly here. The same goes for HY-Plugins HY-RPE 2, which even displays two beautiful modes that can bring different results, depending on how you work with your pattern.

The MeldaProductions’ MCompleteBundle is a complete solution software to help you in your production journey. As it can always get better, every plugin features a randomizer option, meaning that every parameter can have the influence of randomness to either sound more organically or just recreate a specific feature of a vintage unit.

Sugar Bytes’ Turnado focuses solely on effects, but they can act together to enhance your track’s ambiance, modulation, or grit by blending the effects and creating multiple innovative sounds.

The freebies listed here can be alternatives to more complex and expensive plugins, like Surge Synth Team’s Stochas, which provides an excellent plethora of sequencer tools in a clean, lightweight option. BABY Audio’s Magic Dice focuses on reverb, but it totally depends on randomization to offer nice configurations and templates.

This list is a bit more randomized than others (no pun intended), as it features many different and unrelated plugins. If you’re looking for sequencers, multi-FX processors, or drum loop generators, you’ve got yourself covered here. Remember always to try the plugins that interest you before buying them, so you’ll be using the maximum potential of these great sonic tools.

See you next time!
