Patch Request: Shjiva - Upper Limit

Hey all,

Trying to reverse-engineer an arpeggiated synth and I'm stuck on how it's built.

To my ears it's several layers fused into one: a bass layer, a mid synth carrying most of the movement, and at points some resonant high-end elements fading in and out on top. The striking part is how monolithic it is, everything reads as a single voice rather than separate stacked sounds. I can share a short cutout of the synth if it helps.

What I'm trying to understand:

  • Is this more likely one patch (wide/unison with a resonant filter) or genuinely layered bass + mid + top, glued together afterward?
  • How do you get that "one sound" cohesion when stacking? Shared filter/saturation/bus processing, or mostly in how it's sequenced?
  • The resonant top elements that appear and disappear, is that a resonant filter being swept while the arp plays, or a separate layer on top?
