I've spent quite a bit of time working with the wonderful Waldorf Blofeld Desktop Synthesizer. I put together a mindmap of things I've learned that will help you understand the differences between the keyboard and desktop version including the License SL sampling option. Along the way I've also found many links and utilities (such as computer editor/librarians) which I've included in the map. This should be a real-time saver for you.
