<<Because all my stuff is on another partition (D Drive) if your content is on the C drive, Rapture Pro can have an issue locating multisamples, I know that shouldn't matter, just a heads up.
If that is the case, you'll have to locate the multisamples in the sample data folder.>>
This is why I've been reluctant to release any of my Rapture Pro expansion packs. Even transferring among my own computers has caused programs not to locate samples. Cakewalk did create an installer that seems to work well and put the right files in the right places, but it's somewhat confusing to use and you don't really know if you got it right until enough people have installed it without issues.
I still think that despite its loose ends, Rapture Pro is a brilliant instrument.
