this might be a big part of it actually - the automation issue. as i think i may have or maybe just tried to imply lol, in fruity you do have to go to more effort to create variation (create a whole new pattern if you just want a double kick at the end of a phrase, etc), so the arrangement can tend to be relatively basic.
i personally don't think my first couple of tunes in fruity really had the 'fruity' kinda sound, and this could well be because i always had something being automated (quite often loads of things at once)... took me ages to make the tracks too! lol
