Hi all, I'm not good in sound programming but here is my attempt of this song, feel free to adjust and repost it.
The setup is split in 3 parts:
first part [C-1/G#2] : cello like sound for intro
second part [C-3/E5]: plain (background) strings
third part [F#5 / G9]: layers of synvox/voice like sound for intro sound

I played a show with these guys around '89. I was in the opening act. The keyboard player sequenced the whole intro to this song. I asked him why don't you just play it? LOL! He was playing an Ensonsiq SQ2 and I think a VFX.
