For those who care, riboflavin is vitamin B2, and the Weston Precision Audio B2 Kick/Bass produces the big and booming bass tones in the last half of the performance. It is a wonderful module.
You can hear the mixed and mastered audio only version here.
I also used the Weston PAO for the baroque style melody that interjects in the first half and becomes a main theme with variations in the second half. The whole thing was sequenced using my Vector with Launchpad X integration. The main melody is a BIA via a 4MS DLD Dual Looping Delay.
