Anthology XI Support


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.

Mac: AAX, VST2, and AU all in 64-bit only



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.


Hover your mouse over the Eventide logo to find out the version of UltraChannel you're using.


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.


Yes! The same license used by the old FL201 Instant Flanger plugin is used by the new Instant Flanger Mk II plugin, so all you will need to do is download and run the installers for the new plugin.


Yes! The same license used by the old PS101 Instant Phaser plugin is used by the new Instant Phaser Mk II plugin, so all you will need to do is download and run the installers for the new plugin.


No. The Instant Phaser Mk II files have been included all current bundle installers to replace the PS101 Instant Phaser plugin. If you own Anthology X, Anthology XI, or the Ensemble Subscription, you can still use the PS101 Instant Phaser plugin alongside the Instant Phaser Mk II plugin.


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.
