Is there any way to load one audio file and set different start points to
different keys or layers?  As of now, if I want to have 10 different start
points of one audio file, I have to make 10 copies of that audio file load
it 10 times into 10 different layers.  This sucks up my memory and isn't
that efficient timewise.  Do I have any other options????  Thanks.
