You will need an iLok (What is an iLok?) with the latest iLok drivers installed. Where do I find the iLok drivers?

Then go to the product page for the plug-in that you wish to demo. Click the demo tab and enter your email and iLok account id.

Download the appropriate installer, install and activate the plug-in that you want to try using the Softube Plug-ins Control application. For help, please see: How do I install Softube plug-ins?

Rock on! (or whatever your preferred genre is)
