No - seriously, I just decided I won't get Omnisphere befor I got more into the Oasys. I loved sound-programming and spent many hours with my beloved Roland D50. The synth engines that I find most interesting on the Oasys are the Mod-7 and the MS20. I understand there's a nice step-by-step tutorial on the Mod-7 and that is exactly what I was looking for. So I'll start with this one!

EDIT: BTW I was not aware there are guided tours in the parameter guide as well. I read a large part of the manual of the Op-Guide and that one is stuffed with guided tours (eg. Sequencer chapter or Karma) and it helped a lot.
The parameter guide I only used if I needed detailed information on certain parameters. When I checked the Op-Guide for a guided tour for Mod-7 there was none. So I assumed there is none and one has to know the basics of FM and should use the Parameter-Guide for the details. Which I could not do. I suggest to Korg to make this more "public" when launching a new engine on the Oasys - well, perhaps they did and I overlooked it in the first euphoria ...
