Butterfly Effect FAQ

You will receive an email with a serial number as well as a link to an installer, to the email you provided at checkout.

First, run the Butterfly Effect installer.

If you already have iLok license manager on the computer:
  1. Launch your DAW.
  2. Click ‘Activate’. (If you are not presented with the activation window on launch of your DAW, launch the iLok License Manager, log in to your iLok account and select Licenses -> Redeem Activation Code from the toolbar, and enter your serial there instead.)
  3. Enter your serial number
  4. Choose where to authorize your license to (iLok cloud or iLok key). Each license includes activation on two devices.
If you don’t already have iLok license manager on the computer:

An iLok account and an iLok License Manager installation is required.
A physical iLok key is not required.

  1. Create a free account at iLok.com (Don’t forget to activate the account by clicking the link in the confirmation email).
  2. Download and install the iLok License Manager.
  3. Launch and sign in to iLok License Manager.
  4. Launch your DAW.
  5. Click ‘Activate’. (If you are not presented with the activation window on launch of your DAW, launch the iLok License Manager, log in to your iLok account and select Licenses -> Redeem Activation Code from the toolbar, and enter your serial there instead.)
  6. Enter your serial number
  7. Choose where to authorize your license to (iLok cloud or iLok key). Each license includes activation on two devices.


* Online access is required for the initial activation of Butterfly Effect or the Demo

You do not need a physical iLok key to use Butterfly Effect. You do however need a (free) iLok account, and the (free) iLok License Manager app on your computer to use the Butterfly Effect or the Demo.

Yes. Click the ‘download demo’ button’.
Download the installer and run it. When you launch your DAW you will be presented with the option to run a 7 day, fully functional version of the plugin. Click ‘Try’ to activate the demo.
After 7 days you will have the option to activate the plugin with a serial you receive if you purchased the plugin.

Note that you need a (free) iLok account, and the (free) iLok License Manager app on your computer to use the Butterfly Effect or the Demo. See installation instructions above.

  • macOS: 10.13 or newer.
    Usually works on 10.12 but not officially supported

  • DAWs: All major DAWs that support 64-bit VST3, AAX, or AU

  • Native support for Apple Silicon chips

  • Windows: 8.1 or newer
    Usually works on Windows 7 but not officially supported

  • DAWS: All major DAWs that support 64-bit VST3 or AAX

Each license includes two authorizations (aka activations), both of which need to be associated with the same iLok account. For example you can authorize the license to your iLok Cloud and to an iLok key, or to two iLok Cloud sessions on two different computers, as long as they use the same iLok account.

Try to rescan your plugins. Here is a good walkthrough on how to do so.

If that doesn’t work, close your DAW, re-install Butterfly Effect with the installer, then launch your DAW again. If necessary, rescan the plugins again.
With Ableton Live we’ve found that that ‘hard’ rescan where you hold down the ALT or Option key when clicking ‘rescan plugins’ is often helpful. This will rescan all your plugins so may take a bit longer.
If that doesn’t work, confirm your OS and DAW is supported in the compatibility question above.

It’s possible you don’t have an iLok Cloud session open.
In your iLok License Manager, click File -> Open Cloud Session.
You should now be able to authorize Butterfly Effect to iLok Cloud.
If you still don’t see the option, sign out of your iLok account in iLok License Manager, and then sign back in.

Butterfly Effect has a free, 7-day fully functional demo for you to try the plugin before you buy it, ensure you like it, and that it is compatible with your system.

Nonetheless, if within 7 days after purchase you have not authorized your serial, you can contact the SoundBetter support team to request a refund. Once 7 days have passed from the purchase date, or if you authorized your serial to your iLok account, no refund will be issued.

The Blur section was designed to have a slow, patterned build-up. Input signal is routed through the Blur engine by default, which slows down the overall attack time. To accelerate the attack time, you can:

  1. Turn the Mix down in the Blur section. This will bypass or partially bypass the Blur section.
  2. Turn the Blur Density down, and/or turn the Blur Pattern up. Both things will impact the buildup character of the blur section. Density represents the density of the echo lines that form the Blur reverb. Pattern is the pattern of those echo lines. Low value is irregular & patterned, high value is more linear.

The Note feature is designed to drive (accentuate) notes from within a signal passing through the Blur section.
Choose the track’s key, and then select which notes you want to drive with the Note knob. You can ‘play’ different notes in different sections of a track, and automate your changes. You can assign a midi controller knob to play the notes in a more tactile way.

To hear driven notes more prominently, make sure those notes exist in the source material, or turn up the drive, or turn the Blur feedback up.

If any distortion is introduced, use the ‘Less’ button below the Note section, or turn the drive or Shimmer down, or turn down the ‘out’ fader in the Master section of the plugin.

The Sweep function creates a sweep post-Blur and pre-Space sections, which adds movement and excitement to the track.

You can set the sweep to lock to the tempo of the track, or sweep manually.
You can also assign a midi controller knob to the sweep knob, for a more tactile sweep experience.
The Sweep feature was thoughtfully designed to enable you to fade into a sweep, to sweep, and then fade out of a sweep (at either low or high frequencies), all with one knob.

If the Sweep is too strong or distorting, click the Less button, or turn down the input signal, Shimmer or Saturation signals, or turn down the plugin’s output signal.

Ducking will ‘duck’ or downward compress the wet signal to the dry signal. This is useful to ensure the wet signal doesn’t drown out the dry signal, and to clear room in the mix. Everytime dry signal is detected, the wet signal is compressed downward to clear room, and returns to full level depending on the Release settings.

Sidechain will ‘duck’ or downward compress the wet signal to the signal from another track. For example you could pump a Butterfly Effect’s wet signal from the rhythm of a kick drum. You will need to set the external signal (ex. the kick drum in this case) as the ‘key input’ on the plugin or track in your DAW.

The Frequency knob controls which frequencies are downward compressed in Ducking and Sidechain mode. For example you can duck mid/low frequencies to clear room in the mix, while not touching the high frequencies which are more easily audible when ducked. So room is created in the mix and felt, but the ducking isn’t heard as easily. Moving the Frequency knob engages ‘listen’ mode, which isolates which frequencies are being compressed.

Release time determines the release time of the compressor in the ducking and sidechain modes. Sync will synchronize the release time to note values based on the session’s BPM.

  • Open a midi track in your DAW.
  • Set the ‘midi in’ on this midi track to your controller.
  • Set the ‘midi out’ to ‘Butterfly Effect.’
  • Record-engage the midi track.
  • Right click the Sweep/Note knob on Butterfly Effect, and then turn the knob on your controller.
  • The Sweep/Note knob should lock to your controller’s midi knob.
  • The midi track will need to be engaged to receive midi signal and control the Sweep/Note knob.

Shimmer, Blur and Space are the three Reverb engines in Butterfly Effect. They feed into each other in that order. Each has a different character. The best way to get to know them is to run signal through each in isolation. You can turn any of the Reverb sections down or off using its respective Mix knob.

These modes refer to the decay time of the reverb in the Space section. In Undercurrent mode, the low frequencies take longer to decay than the high frequencies, the result being a dark tail. With Bloom, the high frequencies take longer to decay than the low frequencies, the result being a brighter tail that feels like it’s opening up.

There are many beautiful reverb plugins out there. Butterfly Effect was designed with a number of specific sounds in mind – usually long, lush and slow. However if you want a more standard reverb sound, turn the Shimmer and Blur sections down, and use the Space mode with a short feedback time. You will also find several presets designed to provide a more standard reverb sound that we think are quite pretty.

Interested in how background impacts the perception of foreground, and searching for ways to add atmosphere to songs & tracks, SoundBetter founder Shachar went down the rabbit hole. He was intrigued by how many of the songs that move him have an interesting element in the background you can barely hear, but if removed, just wouldn’t sound the same. To create the types of atmospheric tracks he was after usually requires multiple tools and automation. You could play an ambient instrument from a synth or sampler, but they often sound like another instrument, and don’t typically affect the way you would play the main instrument in the same way that a reactive and slightly unpredictable ambient reverb can. He and the SoundBetter team decided to build a tool that would capture and make accessible the sound he was after, with the features he wished existed.

-Go to C:\Program Files\Common Files\VST3 and find Butterfly Effect.VST3

-Change the filename to remove the .VST3 extension. This should turn this file into a folder.
-Within this folder find the ‘Contents’ folder, and in it the x86_64-win folder. In it, find a file called Butterfly Effect.VST3
-Move this Butterfly Effect.VST3 file to the main VST3 folder here: C:\Program Files\Common Files\VST3
-Relaunch your DAW, and begin a rescan of your plugins folder.

Launch Logic’s ‘plugin manager’, select butterfly effect, and press “Reset & Rescan Selection.
Restart your computer, and relaunch LogicPro
This is typically due to one of 2 reasons:
-You already activated one of the licenses to your iLok Cloud Session
-You don’t have a cloud session open in iLok License Manager. 
You can open a cloud session by clicking file -> Open Cloud Session in iLok License Manager. 
You may need to log out and back in. 
Make sure you have the most recent version of iLok License Manager software.
