I created two sound generator chains in Sunvox. The first was a Spectra Voice sent into a reverb. The second was another Spectra Voice side chained with a pitch shifter, then sent into another Reverb. I entered in randomly, then played them back at a low BPM. I then outputted each chain separately.
I used identical settings and stretched each track with Paulstretch.
I then used Audacity for basic mixing and effects.
