Synthesist Hainbach shared this video, demonstrating his approach to creating quadrophonic performances, live with a Eurorack modular synthesizer.

“For Bauhausfest 2017,” notes Hainbach, “I created a quadrophonic modular performance using the Koma Elektronik Poltergeist.”

While you can’t get the full quadrophonic experience from the video, listening with headphones will give you an idea of the spatial ideas discussed in the video.
