Emu XL-7 & MP-7 User's Group

I just bought my XL-7 and have gone through the manual about 5 times 
now. Basically all I am trying to do is take a preset and use one of 
the arp patterns that is under the ARP menu. Everytime I try all I 
get is nothing...if that. Can someone please help me please. I am 
losing extreme patience with this. IF anyone has the time or care to 
respond it would be greatly appreciated. Thanks
