I’ve been able to get some pretty good “Wake Of The Flood” ending solo tones out of my Voyager, but I just caught something the other night on Mars Hotel I’d like to try.
On “Loose Lucy”, during the “Yeah… yeah… yeah… yeah” part there is a very cool modulating patch in the background. LHS. 
Sounds like a little envelope filter with some nice swirlys thrown on top.
Anybody know what I’m talking about.
