KOMA Elektronik has posted a  video for their new Poltergeist eurorack module, which has just started shipping. This is what they have to say about the video:

Analog quadraphonic sound recorded with a binaural microphone to illustrate quadraphonic sound best in stereo. The video starts off with the Bastl Tea Kick which is panned to all outputs with the field control. The bassline's panning is sequenced with the Komplex Sequencer. The noise hats come in and are sequenced via sample and hold. Lastly the pad is panned around from the Master Origin from a Intellijel Dixie sawtooth wave.

NOTE: Wear headphones to experience this video correctly. This is a binaural recording of the Poltergeist in a quadraphonic room to best display its capabilities in a stereo setting. Recorded with a Neumann KU-100 binaural mic courtesy of Bohemian Drips in a quadraphonic studio with Neumann KH-120 monitors at Noize Fabrik, Berlin.

Here's a description of the module direct from KOMA Elektronik:

The KOMA Elektronik Poltergeist Analog Quadraphonic Audio Mixer / Panner / VCA. is unlike any other eurorack module that has previously existed. Previously you would need multiple modules from various manufacturers to achieve something similar to what we perceive as quadraphonic sound. But now with one single module, you can mix and control signals quadraphonically with complete control and beyond. Four channels each with it's own VCA, plus a stereo auxiliary input, are mixed out to four separate outputs enabling the user to manipulate signals both stereophonically and quadraphonically in entirely new and ghostly ways with its 21 ins and outs, 48 analog SSM VCAs and unique hands-on mixing features.

With performance in mind when designing the Poltergeist, KOMA Elektronik included large Pan knobs for total control over the 360 degree range field. Also, clickless solo and mute buttons allow for effortless and instantaneous changes on the fly. Beyond these controls, you can also tailor your sound with extreme detail using functions such as Slope, Field and Origin. With just this mixer, some audio sources and a couple of LFOs, extremely complex sound design can be achieved.
