Hi Alex,
Glad you got it sorted - it's definitely a bit confusing to start with, took me a few hours, watching vids, reading, playing about and head scratching :-)
Check the Spectrasonics site for video tutorials too, they have quite a lot of good stuff over there.
Make yourself a template with the 8 Midi tracks already set up too - it's a lot easier and quicker inserting from a track template :-)
I think the most annoying thing I find with Stylus RMX, is the audio channels all default back to 'A' when you change/audition patches (if I remember correctly).
It's a mighty awesome tool, spend some serious time with it and get to know it ... you certainly won't regret it !.
Cheers - Cliff
