A few examples come to mind and I guess one could cite many prog rock/metal etc albums here, so I will refrain from doing so, with three little exceptions hidden in this list:
* Chroma Key’s Colorblind
* Dream Theater’s Images and Words album, literally heavy use of synths
* Jan Hammer’s Miami Vice soundtrack(s), eg Escape from TV
* Judas Priest’s Out in the Cold
* Porcupine Tree’s Up The Downstair
* Pretty Maid’s Love Games
* Shadow Gallery’s Carved in Stone, among which Ghostship;
* Van Halen’s 1984 intro ;-)
