I just got 3 expansion packs and installed them - 2 for DimPro which showed up where they're suppose to, and the DSF Bass Pack for Cakewalk Sound Center that I can't find anywhere. In fact, I've installed it a 2nd time, thinking that somewhere during the installation it might tell me where it was going. I've looked through all the download folders and Cakewalk folders. I've searched for the name of the download file, but the actual installed file must have a different name. I don't know why this isn't more user friendly. Help.

In my machine.....

c> program files > cakewalk > vst plugins > cakewalk sound center > modules > multisamples > dim pro   

this is where a bunch of the CSC stuff is located that I bought as the add on sound packs.....Steinway Grands and world sounds. They are in the Dim Pro folder but I can access them from CSC. 

Hope this helps. It took a bit of looking to find this.

Well, that's where I found my DSF Steinway Grand stuff (the only other CSC pack I added), but my DSF Bass stuff is still hiding somewhere else...

... It's gotta be here somewhere,... I've installed it 3 times now... ??
