It was made entirely with Omnisphere. Three instances with all slots used up.
The song was born as I noticed that Omnisphere's editors (and indeed all tutorial videos) seem to prefer the 4/4 variety. Especially the famous envelopes. I wanted to see if I can make it work in the 3/4 world, and triplet-driven to boot. Especially the famous envelopes.
