Although probably makes more sense for SS2 due to the predictability of the source soundset.
Anyway today I attempted to recreate the 'classic' "Universe" combi from the Korg M1 (going from memory because I sold mine years ago).
Well since I can't post the preset here's how I did it. Choose your favourite choir sound in SS2 - I like "Vocal Textures/Don't Cry" but for a more authentic sound (IIRC) use "Vocal Elements/Misc Vocal Elements/FemChrAh" and increase the Release and Attack times in the volume envelope to taste plus add a delay or reverb effect of your choice. "Don't Cry" didnt need tweaking as it already sounded fine as is.
Next add "African Rattle 1" from the "Perc Elements" as part 2. Add a Delay effect with params thus:
Mode = "Dly LCR"
Feedback = 73%
D.Time = 0.3s
Level = 89
BndWidth = 11.2Khz
That should give the tinkling sound that I seem to remember.
Make both parts respond to same MIDI channel and hopefully the result sounds a bit like "Universe" from the M1. Actually, to enhance the effect, play any chords with a slight hint of delay between each finger
