Update: tutorial uploaded where I badly demonstrate how this was put together!

Ambient piece using the 2D wavetable model of Nodi, a new polyphonic Braids clone from the Sanguine Mutants collection. It's fed into Valhalla Supermassive, then two loopers pitching it down one or two octaves, with one also reversed (the venerable Nysthi Simpliciter). Also added some lo-fi samples made from a Korg Monotron overdubbed on to 4-track, and some bass pads from a Pigments patch consisting of a couple of looped waveforms sampled from an old Akai SG-01v sound module, with a sine wave for sub. A few sound effects were also dubbed on in Reaper from another VCV patch - one sample is a binaural recording of an overflowing gutter triggered at different octaves, the other one sounds like water but is actually a vocal sample processed through VCV polyphonic effects with filters and feedback loops.
Considering a tutorial on some of these processes, but probably won't have time for a few weeks.
