A: Before You Begin

You will need to provide three peices of information as part of this process:

1. User ID & License Manager If you don’t have an account, you can create one for free by visiting Download and install the free iLok License Manager to activate and manage your plug-in licenses.  2. Eventide Account If you don't have an Eventide account, Click here to Register. A confirmation email will be sent after completion. If you don't see it, check your spam folder. 3. Serial Number & License Key

The Serial Number will be two letters followed by 6 numbers (i.e SR-######). The License Key will be 3 sets of 4 characters, a letter or a number, each; like XXXX-XXXX-XXXX. 

Received a free plug-in? If you received a license for UltraChannel or EQuivocate through a giveaway, they cannot be registered to your Eventide account. Ownership (and upgrade eligibility) is verified via iLok. Installation files are available here.

Registering Your Plug-in with Eventide Register your plug-in using your Eventide account, iLok user ID, serial number and license key. Activating Your Plug-in Find your plug-in license in the iLok License Manager and activate it on your computer. Download the plug-in installer and run it on the same computer as your DAW and iLok License Manager. Launch your DAW. If you do not see the plug-in, you may need to rescan.

Using iLok License Manger, you can activate the license in two separate locations, each of which can be either a computer, or an iLok license key. You can move these licenses at any time using PACE's iLok License Manager software.

Fission/Physion Name Change


In order for you to see the name change, do the following:

Ensure your computer has Internet access Launch iLok License Manager Go to Preferences > Licenses and select Remove Account Data Saved On Computer Relaunch iLok License Manager and sign in

Simply download and run the Physion installer for your OS. You may also want to update the license name in iLok License Manager. For instructions on how to do that, click here


Some DAWs cache the names of plug-ins in their general settings, or in session settings (e.g. for insert names). Resetting the DAW’s cache files and rescanning your plug-ins should fix this issue.

In particular, if you are using Logic Pro or GarageBand, you can reset the cache with the following steps:

Close the DAW Delete the following files from your User Library, if they are present: ~/Library/Caches/ ~/Library/Caches/AudioUnitCache/ ~/Library/Caches/AudioUnitCache/ ~/Library/ Reopen the DAW

If you are using REAPER, the plug-in name will update in the Add FX menu, but not in the insert field of sessions previously created using Fission. This is because REAPER stores the insert name locally when you first add the plug-in as an insert. You can right-click the plug-in insert, and select "Rename FX Instance", to update the name.

While these are currently the only known DAWs with this issue, it is possible that other DAWs might have the same issue. Clearing the plug-in cache will likely solve the problem. And, even if your DAW still displays the old name, as long as the actual plug-in UI says "Physion," you have updated correctly.


Yes, the license is the exact same. In iLok License Manager, you may notice that the name of the license is still "Fission." You can update it by following these instructions.

Whether you update the name in the iLok License Manager or install the updated plug-in, your license will still work. If it does not, please contact support.


There is no requirement to update, though we strongly recommend you do so, if only for consistency with online documentation, support, etc. Plus, by updating to Physion you will benefit from ongoing bug fixes and optimizations.


They are the same plug-in. The name change is simply that and only that. Physion IS Fission!


The change is effective immediately.


There is 100% session compatibility between Physion and Fission so you will not lose any settings or presets.



Eventide plug-ins do not require an iLok USB dongle, but to activate, you need an iLok user ID and the free software iLok License Manager. Visit for more information.


In order to authorize your plug-in you need to install the iLok License Manager from and activate the license to your computer or iLok license dongle. Even if you have a licensed iLok plugged in, the iLok License Manager must be installed.

Note for Mac users running 32-bit DAWs: Eventide no longer supports 32-bit installers, which could also cause this issue in your setup if you are running current plugins on an old platform.


There are several reasons you may see this error, but a common one is a mismatch of the serial number format. All Eventide plug-ins have a serial number in the form of XX-###### where XX represents a two letter sequence defining the product type and ###### is a 6 digit number. All plugins also have a 16 digit license key in the format ****-****-****-**** where each * can be either a letter or number. The license key is entered on the second page of the registration process.

If you believe your serial number and license key are entered correctly, please contact our Support department and we will solve the problem as quickly as possible.



Simply right-click the Eventide logo on your plugin and select "Copy Support Information to Clipboard". Send an email to with a description of the problem and paste the copied information with your message. Please note that this function is not available on most older release versions of our plugins.


A: Eventide has its own preset format using .tide preset files. By default the installer installs the .tide presets to your Documents/Eventide/<Plug-In Name>/Presets folder on Windows, and Music/Eventide/<Plug-In Name>/Presets on Mac. It may be necessary to check that the installer has placed the presets in the proper location. You can load these presets using Eventide's Preset Bar which is part of the plug-in GUI itself. Some hosts have their own preset bars which are used by the host. Eventide's .tide presets will not show up in this preset bar. To load an Eventide Factory Preset you have to use the preset bar which is inside the actual plug-in GUI, usually below the hosts preset bar.
A: If you have installed and authorized your plug-in and it still doesn't show up in your DAW, try the following: Mac OS X:  Simply go to your DAW’s preferences and rescan your plug-in. Note that Eventide no longer supports 32-bit plugins. Windows:  It is possible that you need to add the following paths to your DAW’s list of VST folders. Open your DAW’s VST Preferences and add the applicable folder: Windows 32-bit OS:  32-bit DAW: C:\Program Files\Common Files\Steinberg\VST2\ Windows 64-bit OS:  32-bit DAW: C:\Program Files (x86)\Common Files\Steinberg\VST2\ 64-bit DAW: C:\Program Files\Common Files\Steinberg\VST2\   After doing this, perform a plug-in rescan in your DAW. Note that the following DAWs sometimes require additional steps: Studio One: In the VST preferences, and make sure "Scan at Startup" is checked. Also click "Reset Blacklist" in the VST preferences, and then restart Studio One. Cubase Go to Devices->Plug-in Manager and click Plug-in Manager->Rescan all. Occasionally Cubase needs to be forced to rescan the plug-in folder.
