Hiya Grant,
I would be into Numan and the like also, that analog classic synth sound. Add to that Vangelis, Tangerine Dream, Eno, Jarre.
For that sound the best investment I made ( in my opinion only, others may differ ) is the ARTURIA synths.
https://www.arturia.com/products Just click on ANALOG CLASSICS along the horizontal menu with black background.
The best deal is the V Collection which includes the lot ( 17 vst synths ) :
https://www.arturia.com/p.../v-collection/overview Dont despair at the €499 price .. :D .. Arturia do regular great sale prices for this at sites like Plugin Boutique, so keep an eye. I managed to pick up the V Collection Version 4 in 2015 for $149 .. then in May 2017 upgraded ( via a native instruments offer ) for €83 for V Collection 5 .. but that gave me extra instruments also.
Another more affordable option is to JUST BUY the ANALOG LAB Vst / Instrument for €89. This is a one stop shop with the best of from all the individual synths in the V Collection. It would also get you in the door for deals to buy the full V Collection further down the road. But the ANALOG LAB might be a good start for you without breaking the bank.
https://www.arturia.com/p...ics/analoglab/overview All these vst synths are emulations of the real thing used by Numan, T Dream, Jarre etc. TBH .. these alone covers everything for that retro feel and sound. I am now on a 12" core i7 laptop with Sonar and ONLY the Arturia stuff so I can focus on that sound without getting way laid by other VSTs :D ..
BTW .. all have demos. I love them all. And really like the SEM V. Great arpeggios ..
