Dwarfcraft Devices latest hit "Happiness" is showcased here, interfacing with bass guitar, analog synth, and sampler. This video also illustrates the technique behind "that sweet song at the end of the Happiness demo."
The Happiness' LFO modulates the internal filter, which effects the bass guitar. That same LFO is also sent to the Electribe Sampler 2 as a clock. And yes, that SAME LFO is also modulating the filter on the Arturia Microbrute.
