Patches and discussion for Ensoniq VFX family

Hi all - 

I'm an old time VFX-SD user, and still love the thing.  I've been using it mainly as a 
performance keyboard, but I'd like to more fully integrate it into my MIDI setup, which is 
Mac based (OS 9.2), with an older version of Cubase.   

Right now, I'm able to back up the VFX-SD with a Sysex Librarian program that runs in OS 
X on a laptop, but I'd like to be able to edit patches via computer...via some sort of a 
librarian editor.   

Anyway, just wondering what's out there, Mac-wise.  If there's not much there, I'd be all 
ears for any PC alternatives (Windows, Linux, or whatever!).
