1. Syntorus

by D16 Group


Syntorus owes its astounding character to the precise model of a high-quality analogue delay line

There are many different chorus effect plugins available on the market today. However, finding one which gives the classic analogue chorus sound is easier said than done. Even on expensive units with advanced parameter controls, getting that vintage chorus timbre can be a challenge.

With this in mind, D16 set out to create a plugin which would have a rich analogue chorus similar to the effect found on classic synthesisers like the Solina, Synthex or Juno. This new effect is called Syntorus and is the latest addition to the Silver Line of plugins.

Syntorus has a unique sound which will add richness to any instrument it is used on. Synthetic basses and leads will come to life. It will also add extra depth and lushness to acoustic instruments. Whether you are an electronic musician, a traditional keyboard or guitar player, we are sure you will be impressed!

Now for the science… To create a chorus effect, an audio signal is mixed with one or more delayed, pitch-modulated copies of itself.

2. ChorX

by XILS Lab

Chor’X combines four types of Vintage Chorus effects, based on Bucket-Brigade Delay (BBD) emulation with a sophisticated True Stereo Dynamic Spatializer.

With this duo, it becomes very easy to add space , depth, and other dimensions to your instruments, and achieve complex and intriguing mixes.

The new Legacy/Advanced feature allows a fast workflow to choose and tweak your prefered chorus model.

You want only a standard famous chorus algorithm ? Keep the Legacy view, select your specific mode, that’s all ! Just add a bit of space by moving the outputs in the Stereo field.

You want more, would like to change a bit the LFO rate or Amount of your chorus model ? Click on the Advanced button and change the Chorus parameter as you did with the previous Chor’X version.


Chor’X 1.5 offers

  • Easy and Fast workflow with the Legacy/Advanced mode  
  • Four Bucket-Brigade Delay emulations
  • Four standard chorus structures (with special filtering and compander emulations)

3. Ensemble Snapin

by kiloHearts

Ensemble Snapin

The Ensemble effect creates the illusion of many voices playing in unison. Much like a chorus, it creates this effect by playing delayed copies of the incoming sound. On top of this, it also modulates the phases of each voice to create a silky smooth result without any metallic flanging. The delay times for each voice is also modulated in order to detune each voice slightly.


  • Voices: Number of voices to play simultaneously.
  • Detune: How quickly to modulate the delay for each voice, affecting how detuned the voices will be.
  • Spread: Pans voices left or right for a stereo effect.
  • Mix: The dry/wet mix of this effect. A lower value will let some of the unmodified signal through.
  • Motion: Selects between different patterns for the modulations of the voices.
  • Settings panel: Whenever you have your mouse cursor over a snapin there is a small arrow at the top right corner (not visible in screenshot). It opens a settings panel where you handle presets. It also has a “randomize” button that can be useful. I guess…
  • Enabled checkbox: The small checkbox to the left of the plugin name is a checkbox that bypasses the effect when disabled.
  • Resize handle: The bottom right corner of all Kilohearts plugins is a resize handle for scaling the UI to any size. This allows you to get a good view of the controls whatever the screen resolution, and also comes in handy if you need big controls, e.g. when using Ensemble as a real-time effect on a touchscreen monitor during a live set. (This is not available when the snapin is used inside a snapin host.)

System Requirements

These are the minimum recommended system requirements for running snapins.

CPU: 2 GHz or faster

Memory: 1 GB or more

Operating System: Windows (7 or newer) or Mac OS X (10.7 or newer)

Software: A VST / Audio Unit / AAX compatible DAW

Supported formats: AAX, AU, VST2, Snapin

4. Blend

by Sinevibes


Blend is a multi-voice chorus comprised of up to 16 separate layers. Each of them actually is a chorus effect on its own – complete with a dedicated modulation generator and a feedback loop. Even with all 16 layers activated, the resulting mix is dense yet always silky smooth and musical – thanks to clever proportional phase offsets. Blend also has three different interpolation algorithms, each giving it a slightly different sound character. And as much as it excels at creating delicious chorus and ensemble effects of many, many styles, Blend’s unusual flexibility allows it to easily go into much further territory – so effects like vibrato, tape wow, flanger, dissonance – even reverb – are just a few tweaks away.

As always with a Sinevibes product, Blend has a carefully crafted, clean and intuitive user interface. It features colour-coded graphics for consistency with other plugins in our collection and well-calibrated contrast for optimal visibility in most lighting conditions. The interface supports retina resolution and also uses GPU-accelerated rendering, never impairing audio processing.


Sound Engine

  • 16 chorus layers each with an individual feedback loop. 
  • Three selectable interpolation algorithms: vintage, character, modern.
  • 16 sine wave modulation generators, one per chorus layer, with proportional phase offsets.
  • Variable stereo width and low frequency cut.

Graphic Interface

  • Colour-coded graphics with subtle animations.
  • Fully hardware-accelerated rendering with support for retina screen resolution.

System Requirements

  • Works with any application that supports Audio Unit effect plugins.
  • Supports OS X 10.6 or later running on 32 or 64 bit Intel Macs.

Important Notes: 

  • This software is Mac compatible only (Audio Units) 
  • An Audio Units (AU) compatible DAW is also required to run this software
  • This software will not function on PC computers

5. MChorusMB

by MeldaProduction


MChorusMB is a unbelievably sounding powerful multiband chorus which allows you to fully adjust its shape. Where other choruses end, this plugin just starts off. It processes anything from guitar tracks to complete mixes, all with outstanding audio quality and an inspiring set of features.

System Requirements


  • Windows Vista / 7 / 8 / 10 (32-bit or 64-bit)
  • VST / VST3 / AAX compatible host (32-bit or 64-bit)
  • Intel/AMD processor with SSE2 support

Always use 32-bit plugins in 32-bit hosts, or 64-bit plugins in 64-bit hosts!

64-bit plugins can’t work in 32-bit hosts even if the operating system is 64-bit. Do NOT use 32-bit plugins in 64-bit hosts. They would have to be bridged and can become slow and unstable.

Mac OS X

  • Mac OS X (10.7 and newer, 32-bit or 64-bit)
  • VST / VST3 / AU / AAX compatible host (32-bit or 64-bit)
  • Intel/AMD processor with SSE2 support

6. EARevolve

by eaReckon


EARevolve is the combination of a stereo chorus and a (mono to stereo) rotary speaker. 

All-in-one, this plug-in is a flexible tool that adds depth and/or controlled movement to your sounds. It is particularly effective when you want to turn a mono signal into a dynamic and deep stereo sound.

Stereo Chorus

A stereo chorus is a very efficient way to give stereo width to a mono sound (or to enhance it when the source is stereo). 

When using a chorus with stereo width in mind, musicians usually want to avoid the sense of movement between the left and the right channels that could be introduced by the effect. 

It is not uncommon to hear that a good stereo chorus is the one that you just “forget” until someone turns it off. This kind of chorus effect voluntarily limits the sense of movement and generates a nice stereo depth. 

Even though EARevolve’s stereo chorus is able to do this, it does not limit you to this single application. It gives you flexibility, by adding a nice amount of selected parameters – to help you to go further with your chorus experimentations.

Rotary Speaker

A rotary speaker obviously generates a sense of movement that is not limited to a simple panning. 

The Doppler effect, natural filtering and level variations provided by the rotation of two parts, form a complex modulation effect. If we add the characteristics of the room, the position of the microphones and the position of the cabinet itself, we start to get quite a number of parameters to consider. 

A logical choice could be to limit the number of parameters available to musicians and technicians, by limiting ourselves to the reality of a hardware rotating speaker. Limiting the number of parameters is also an excellent option if we want to let everyone easily control the effect for the musical use it was formerly intended for. 


  • What else could we obtain from it if we could freely manipulate the angles of both the horn/drum parts and even the location of the cabinet itself, from a remote control, like controlling a drone?
  • Why not control the effects of these movements on the sound, forgetting about physical reality, and use them to our musical advantage?
  • Finally, why not synchronize all of this to the tempo of our music, or automate the whole thing?

These are the questions that led to the choice of flexibility for the rotary speaker part of EARevolve.

Advanced Control

That said, my intention was not to provide a laboratory tool but a plug-in which is usable in a musical or a multimedia context. The primary goal was to provide a creative modulation effect and not a 100% faithful emulation of an existing device or a realistic positioning tool. 

Considering all these aspects, it was therefore important to create an interface which provides enough controls while not being overly intimidating.The controls that have been implemented are not there only to look pretty. Each of them has a role, which you will quickly discover.If you don’t want to be visually overwhelmed by too many controls, it is still possible to use it the easy way, by hiding the advanced settings, loading a preset and adjusting it with a limited set of essential controls… 

until you feel it’s time to go further with the plug-in’s capabilities 😉
