QuBit Chord v2 is the main sound source in this patch. In unison mode, four notes can be played individually, with Chord keeping track of the harmonics. I use pink noise passed through sample and holds to generate the chord progression.
My favorite part starts at 2:10, where the arpeggio blends in.

Patch notes:
Chord mix out goes through Doepfer A102 Diode VCF, root note goes through Doepfer A163 Freq. Divider and A103 VCF; both go to 2hp Verb and into the mix. The note cv's come from a pink noise source routed through sample and holds (one for each note) that are triggered at different times.
The single outputs of the Chord are routed through a sequential switch (A151) to create an arpeggio. The arpeggiated chord notes run through A108 VCF and a delay (TipTop Echoz) to a stereo panner (A134) and then to the mix.
Envelopes are triggered by clock dividers / multipliers and WMD's Modbox.
The kickdrum is from VPME QD.
