This site, and originally Modulus Music, were born out of a love for electronic music by, Paul Maddox.

Paul has been interested in building electronic musical devices since the mid 1980s, in 2001 Paul demonstrated a prototype version of the Monowave.

In 2002 he started Modulus Music to build and distribute his designs commercially, selling 30 hand built Monowaves globally based on word of mouth. In 2005 after many attempts to bring new designs to the market Paul reluctantly closed Modulus Music.

To Keep up with the latest news, keep an eye on our blog, our Twitter Feed, our Google Plus page or our facebook page.

You're welcome to browse around the site and have a look. Feel free to contact me for a chat about synth stuff, I'd love to hear your thoughts.
