i would also pay, for example how to set it up to get some of those sounds and try to recreate.
here are some examples
.- the main lead

- the background arpeggiator and then the lead starting at 16 seconds
http://www20.zippyshare.com/v/58198902/file.html
- main lead and the short arps starting at 20 secs
http://www45.zippyshare.com/v/18435969/file.html
- main lead, maybe the background sound as well
http://www38.zippyshare.com/v/37753796/file.html
- the bass sound and the main melody

as i said i try to learn how to set up quadrasid and learn how to do those sounds and learn the interface + sounddesign. it is somehow harder than normal synths. and there is no real tutorial at all.
