Are you on PC or Mac?
Anyways, the procedure will be the same, but the location of the folders is different…
PC…
Go to \Users\user name\AppData\Roaming\Steinberg\Cubase 7\Presets.
Mac…
Go to Your Account/Library/Preferences/Cubase 7/Presets/
Do you see a folder named “Input Transformer”?, and, if so, does it contain anything? (if “yes” to both of those, then you should be seeing those presets just fine in Cubase… if “yes”, but you are still not seeing them, then we’ll have to rethink the problem
. Anyways… if “no” to either of those questions…
PC…
Go to the Cubase 7 Program folder.
Mac…
Select the Cubase 7 application in the Finder, and, from the “Action” pop-up in the Finder window’s header, or right-click, to get the Context Menu, and select “Open Package Contents”.
From that folder, locate the Presets subfolder, where you should see an Input Transformer subfolder.
Copy that folder to the missing folder/contents in your AppData (or Preferences, on Mac) folder.
They should now appear on next launch of Cubase.
