Salut Fred,
the french members of this forum posted very interesting songs

(I like)..
The song "Resonance" is from the album "Odyssey" composed by an electronic artist called "Home" (Randy Goffe?) back in 2014.
The Blade Runner -remake is from 2017 (I supposed) and the song is not part of the official motion sound track (almost all song composed by Hans Zimmer) but if you are searching for scenes from this movie the most YT-clips are combined with this haunting synth track...
To realize it, it is tricky because you only have three synth layers...so the result is not perfect but (as usual) a good foundation to tweak it to your likes:
Synth A - a stringy pad (made with a SuperSaw-Waveform) with a bit amount of resonance (haha) to make it sound more "choiry", very long attack an even more longer release combined with a pump-effect.
Synth B - a digital bright saw-waveform with arpeggio set to poly, used in the scene layer II (aftertouch varies the amount of "resonance" - again...)
Synth C - an analog pure saw with filtering set for a brassy sound (the wheel as a morphing source opens the filter a bit) and a delay synced to masterclock
To make it a little more substantial in the lows I added a little bit of Hammond (dark eq-ed and reverbed) and a little bit of lowpassed EP...
Hope you like it(sorry for the playing mistakes... - it's a one take / quick&dirty-recording...).
Cheers
Tim
