Logic Pro 9 Audio chopping (sample editor)

Hi guys

I have just started doing some tutorials on making beats.The guy in the tutorials uses Cubase and Recycle to chop a loop up.He saves all his individual hits as a patch and loads them into Battery for further manipulation with the onboard envelopes.He then manipulates the envelopes in Battery and the note lengths in his arrange by midi.I know if I load my samples into battery I can use the midi in my arrange to program a pattern but can't adjust the note length.Is there a way around this in Logic using Battery so I can adopt the methods of the ones used in the aforementioned tutorial description?

Another related question is,can I save patches from the Sample Editor?

Thank you for your time,it's greatly appreciated :)
