Do you replace parts of loops?

[matthias@bahianet.com.br (Matthias Grob)]

I just got fascinated again about the possiblility to replace parts of
longer loops while experiencing them. Within over 15 sec of loop you
probably like some bit better than the other. The bit you do not like (be
it a colour in your "wash" or a single cord in your sequence), you can
reduce with feedback or even replace straight away with a Replace function.
After listening to the loop enough, you know what you want to change and
thus let the whole idea grow.

I prefer to use FeedBack for this, because it allows to fade or leave a bit
or the old stuff in the background.
Used smother it simply creates a dynamic wave of a previously constant 
sound.

Do you all use such tricks?
For practicing/creating or as musical expression/composition in a final
version?
