Drum Map folder

In Windows 7 it you need to do two things, you need to go into Start/Computer once there up in the Tools menu at the top you need to select Folder Options/View and then select the the Show Hidden Files, Folders and Drives option (this will allow you so see the folder you require).

Now navigate to C:\Users\"Your Login Name"\AppData\Roaming\Cakewalk\Sonar X1Producer and in that folder you will see the Drum Maps folder.

Hope that helps.
