This synth was first shown in 2001 by its inventor Paula Maddox on a PPG user/fan meeting. Because its attraction to some synthesizer players at the event, the project was started with 5 beta-test units to test the software and hardware. By spring 2002. the serial production of a 25-piece limited run started. About a year later, all units were sold.
Late in 2005, after many attempts at designing new products, Paula decided to close Modulus Electronics and its website (modulus-music.com). In order that people could still enjoy the Monowave, she worked with Elby Designs to create a kit version of the monowave offering the same features. The software was released at the same time under the GPL license, in the hope that others would continue to develop its features.
