Not my region of expertese either.
I know Rock, Pop, Hip Hop RnB, even Classical from multiple time periods, but know nothing of Techno/Electronica.
I can give you some names that are overly popular.
The Prodigy
Kraftwerk
Madonna(can't remember the albums, but she had some synthy stuff)
Also, don't overlook Disco/80s stuff.
Yarborough and People
A Taste of Honey
New Edition's old albums
I'm honestly not thinking of many good ones because I usually don't sample synths.
But above all check out Kraftwerk and look for similar stuff. That will put you in the right direction.
