This site is for and by Rob Hordijk synthesizer enthusiasts, it is not the official website of Rob Hordijk. To order or inquire about his modules, e-mail Rob directly:

The reason this site came about was the desire of fellow synth enthusiasts at the great Muffwiggler forum (todo: link to thread) to gather infomation about Rob’s synthesizers in one easily accessible place. We each had ideas and snippets of information from conversations with Rob, with each other and of course from interacting with our synthesizer that we wanted to share.

Rob Hordijk (b. 1958) was trained as a sculptor and jewelry maker in the 1970s. In the late 1970s and early 1980s he became interested to see if sound could be sculpted in a way that is similar to how materials like metals are worked. Electronics seemed a good way to get control over “sculpting sound,” and thus he invested a lot of time into becoming a master of electronics, with the purpose of being able to “sculpt sound.” He has since been building high-end sound-synthesis electronics for his own artistic purposes, such as installations, and on request for other artists. Hordijk has been teaching for over 20 years at the art academy level, giving lectures and workshops on sound design and sound synthesis.
