@JC: I mapped the song-file in "live-play". I think this is the only method to call up the emulator (because RPS is stored in the song-file)? So each time i switch to the emulator i first have to activate RPS and select a Preset - or is there a faster option?
I found some drawbar-registration settings (for ex. http://www.thesoundsmith.com/private/hammond3.htm) - i will try them today

Thank you JC for this great emulator.
