Hi Ulrich, Firstly, are you using a DAW? And are you comfortable with it? Omnisphere is terrific but pricey if you're on a budget. Google "Luftrum Sound Design", he made a VST called Lunaris. Listen to the demos. Its $159. It only needs the Kontakt Player. I have Logic Pro x --but I found it easier to get a multi track recorder and record from my laptop into an audio interface. well, if you have any questions let me know. Frank
