SiO2 is the sonic laboratory and recording space of electronic music artist Arjen Schat (also performing as Ohrwert). Located in the Netherlands, the studio has been the birthplace of deep electronic music, Berlin-school sequences, and dub techno textures since 2016.

Built around a philosophy of tactile exploration, SiO2 houses a curated collection of vintage drum computers, rare synthesizers, and boutique analog hardware. Every sample pack, waveform collection, and instrument bank released under the SiO2 name is crafted here. No shortcuts, no over-processing – just the raw, dynamic power of classic hardware, preserved in pristine quality for the modern producer.

• Artist-driven sound design: Every sound is curated and field-tested through the lenses of deep techno, ambient, and Berlin-school synthesis, bridging the gap between hardware preservation and modern production needs.
• Pure signal integrity: We archive our instruments in their rawest form, capturing the exact voltage variations and EPROM characteristics through high-fidelity preamps and converters without any digital coloring.
• Tactile & documented workflow: Our libraries offer a highly structured, hardware-faithful blueprint accompanied by technical, real-world documentation.
