Emax

Hey guys, I have recentlt blown off the dust on my favorite unit ever.
I once owned an Emax se and a Emax HD with the SE upgrade. I now own 
a rack unit Emax with the SE upgrade but with no HD.

2 MAJOR ISSUES

1. NO DISK! NO OS! I live in LA. Can someone help me out.
2. How expensive is a HD for this unit? Disks are great, but...

I want to use this unit in live situations, probably because you 
can't here the sound degradation on a huge PA. And I do industrial 
music anyway. I like the metalic color in the lower quality sampling 
rates. 

i NEED A DISK AND SOMEONE TO TEACH ME HOW TO USE THE emx files.
