Patches and discussion for Ensoniq VFX family

I recently was able to purchase a VFX-SDii and have old disks from 
both the VFX-SDii and an SD1 unit that I used to own many years ago.  
The disks from the VFX unit are working fine and I was about to try 
loading some sounds and sequences from the SD1 disk and I got 
nervous.  Would it be safe to load some of the sounds from the SD1 
disks onto my unit?  What about the sequences?

I understand that the SD1 has some new waves over the VFX unit... 
would the sounds based on those just not work?  Maybe they would play 
based on some other wave in the VFX lib?

Anyone else try this?

Thanks in advance!
