Wizoo was founded in 1997 by author, sound designer, and studio musician Peter Gorges. His publication included online downloads / pdf copies, and software included in the instructions. “Programming Synthesizers” includes the Soundforum synth (early NI) that has basically disappeared off the face of the planet.
