UJAM is a Berlin-based music technology company founded in 2009 by Peter Gorges, Hans Zimmer, and Pharrell Williams. The company traces its roots to the Steinberg Virtual Guitarist, a landmark virtual instrument released in 2002 at Musikmesse in Frankfurt. Gorges, an electronic musician and sound designer who had worked at Avid, reunited with Zimmer and Williams to build a new generation of accessible, professional-grade audio plug-ins.

UJAM's product catalog spans a wide range of virtual instruments and effects. The Virtual Guitarist series (including IRON, AMBER, and CARBON) covers styles from acoustic fingerpicking to heavily distorted metal. Virtual Drummer (SOLID, BRUTE, HEAVY, PHAT, DEEP) and Virtual Bassist deliver studio-quality rhythm section performances, while the Virtual Pianist line offers realistic keyboard instruments. The Beatmaker series provides electronic drum machine sounds and pattern libraries. Beyond traditional instruments, UJAM offers the Usynth synthesizer line, Symphonic Elements (including orchestral drums and strings drawn from Zimmer's own recording library), the Finisher and UFX effect suites, and creative tools like Voxcraft and Subcraft. All plug-ins are available in VST, AU, AAX, and Reason Rack Extension formats.

UJAM also develops the Gorilla Engine, a sample instrument platform used by third-party audio plug-in developers. The company's design philosophy emphasizes intuitive interfaces and streamlined workflows, aiming to make professional-sounding production tools accessible to musicians at all skill levels.
