If you can't find the Stylus midi files in OSX, you can copy them from the original CD. Put CD1 in, open the Spectrasonics Stylus™ folder, then the Stylus folder, and you'll see the MIDI files folder. Drag it to your preferred hard disc location. If you would like easier access to the folder and you are using the dock in OSX, you can drag the folder from your hard drive to the data side of the dock. (The data side will be to the right or to the bottom depending where you have setup your dock.) Then you will be able to have easier access to the Stylus midi files through this alias that is located in your dock.
