Another newbie EDP question

["american qabalah" <american@qabalah.com>]

I have read that the EDP can store nine different loops. 

 

Question: can more than one of these loops play back concurrently?

 

If the answer to this question is yes, my second question is, how does it handle playing back loops of differing durations?

 

Also, when you overdub onto a loop, does it attenuate the previous sound on the loop as with the boomerang?

 

Thanks
