Music Thing Modular is the hardware wing of the successful music technology blog Music Thing, which ran from 2005-2009 and attracted over 4 million visits.
MTM produces open source, Creative Commons licensed designs for electronic musical instruments. Our first designs have been components for modular synthesizers; the Turing Machine sequencer, a range of expanders for that sequencer and a Spring Reverb module.
The designs are built to facilitate distributed manufacturing; a series of digital files are published which can be used to manufacture printed circuit boards, fabricate front panels or order parts. A number of other companies have made use of the Creative Commons license to manufacture modules and sell kits.
