Skude,
style edit mode on Audya is simple anaf to anderstand and you can edit or record your new style wery easy.Here I thing you dont nead some extra tutorial.
Let me say feu words about:
if you want to edit some track in existing style (let say Bass treck)and want to record new sequence for Bass line,first clear that track.Push F10 buton and hold them.In the left side of scren you see what you want to do.Clear one note,cler all notes and so on.Push desire button.After that simply record new sequence for Bass line.
All recording is in C kay.The same procedure you must record all parts of style that mean A,B,C and D part with Minor ,major and 7th .Allso intro ending and brake parts for all tracks in style.
That procedur is long way to make new Style.Much shorter way haw to do a new style is Style modeling way and you can read abaut in Audya manual.
If you nead some practikal sugestion abaut, you can call me on Skype.My Skype name is :"dusantina1"
