Patches and discussion for Ensoniq VFX family

I am re-posting this question that I posted last week in case anyone 
missed it and since there were no replies......


 ...Trying to get a discussion going on things our VFX users have one
 that successfully reduced the output hiss on the synth (I'm just
 beginning to notice it would you believe!)....some things I read in
 the past messages:
 
 --Keep the volume pot at max since it is not really an independent
 volume control but part of the VCA (are there any internal mods to
 help ?)....
 
 --Replace the output op amps with quieter ones (which p/n worked 
well ?)
 
 --Use a noise gate on the output
 
 --What else has worked (or what has not)??
 
 Thanks
