This patch uses the Surge XT Nimbus module (a clone of the infamous Mutable Instruments Eurorack module called Clouds) with polyphonic processing, where a signal is copied onto 16 channels and processed by a separate instance on each channel. The keyboard sound is actually the Surge XT filter being excited by a short burst of noise in comb filter mode. This is basically a resonator, similar to how the Rings module works, also by Mutable Istruments. In other words, this is yet another 'Rings into Clouds' video, that old cliché in the world of ambient modular.
