Keyfax invented, designed, and manufactured the Phat.Boy MIDI Performance controller in 1998.

Phat.Boy became an award-winning industry-standard for the controller market, not only for laptop DJs/producers, but also for large-scale installations and music/video studios.

Phat.Boy ceased manufacture in 2002 after many thousands of units were sold, and indeed still remain in use, throughout the world.

Though Phat.Boy was much copied, no subsequent controller device has captured the imagination or generated such sales. In 2004 Keyfax will be distributing the Mercurial STC-1000 “Flat.Boy” to the music industry. This innovative product offers much the same leap of imagination as did Phat.Boy, providing not only the opportunity to be a custom controller device for a wide range of software sequencers, synthesizers, and effects, but also as a highly sensitive, ‘instrument-style’ controller for tabletop drummers and beyond.

Keyfax has also developed several proprietary controller designs for the music/computer industry
