The ZIP file contains 4 folders. One contains the VST bank file (.fxb), the second the Single VST patches (.fxp), the third the AU patches for Mac and the 4th both an Init bank and the Init patch for the VST version.
Currently my bank contains 4 Bass sounds, 7 Keys sounds, 4 Lead sounds, 16 Pad sounds and 6 synth sounds (those contain 4 Synth Brasses).
