After installing a Toontrack plug-in you will need to let Cubase know where the new VST plug-in is installed. Depending on your operating system and the bitness of the plug-in, the location can be slightly different.
Please note that if you choose a custom path for installation, the above paths will not apply. They may also differ in some instances, should the installer be able to probe your system for a pre-existing VST repository.
Tip: If you didn’t make a note of the VST install path during the installation, there is a way to find out where the plug-in was installed, in case the product comes with a standalone application: Launch the standalone, open its Help menu and choose Show Plug-In Path. The path displayed (minus the last part, the dll name) is the path that your host application (Cubase) will need to know about.
As stated earlier, once the plug-in has been installed, it will be necessary to ensure your host recognizes the installation path, should it not appear listed among your VST plug-ins already. To set the path to the plug-in file in Cubase, open the plug-in manager and enter the appropriate plug-in path to the VST Scan Path. This operation is performed slightly differently in the various versions of Cubase. The following applies to Cubase 5 at least. Open the plug-in manager and click ‘VST 2.x Plug-in Paths’.
Click Add, and navigate to the location that the plug-in file is on your hard drive (default paths previously listed).
Finally, in the main page of the plugin manager, click Update and your Toontrack plug-ins should appear under the found plug-ins.
You will now be able to launch your Toontrack plug-in in Cubase.
