At that time (around 1995), he began to build a studio in the basement of his family home. His former equipment included, among others, an Akai S1100, a Korg Prophecy, a Roland JV-90, a Yamaha QS-300 and some analog classics, e.g. a Roland TB-303 or Roland JX-3P.
Starting in 1996, he begun working on first contracts for events and multimedia applications.
At the age of 17 (in 1997), he founded his own company Amadeus Paulussen Sounddesign, which he later renamed kubus media.
He published in 1999, together with Daniel Sgubin (DJ Mystery), a first production in a vinyl small series, on a sub-label of DJ Beat (a Swiss vinyl records-chain): Modular Records.
Further vinyl releases did follow, with Tihomir Markovic under the pseudonym Pushing Elementz and with Francesco Cali, under the name Paulussen & Cali on DJ C-Rock’s Label Lo-Fi Stereo.
In the years 2002-2015, as managing director of kubus media, he could perform numerous jobs in the area of corporate sound for clients such as Swisscom, ALPA, David Klein and Basler Versicherungsgesellschaft.
Since 2014 he runs the kubus media studio in Basel together with Chris Air.
