I know it won't really be helpful to many people but lately i've found myself recording a sample then extracting a section I thought I wanted as one sample....but in turn extracting another section out of it and then another smaller one out of that extraction....of course if you keep each step of extractions and make a program it can turn into something pretty ****in beautiful!
I know this may be the norm for some people but others may not know.....I always think of one of those russian dolls when I chop that way....this is an alternative to getting a simple two bar loop and choppping it in to 16 equal parts.
