DIY Eurorack Synthesiser Projects


Oakley Sound Systems have been producing DIY synthesiser modules for over two decades and on this page you will find my growing range of Eurorack designs.

Oakley modules are designed to be constructed by yourself using our bare printed circuit boards. Full building instructions can be found on each of the project's own webpage.

For technical support on all Oakley projects please refer to the knowledgeable and helpful Oakley Sound Forum which is hosted at Muffwiggler.com. Tony Allgood at Oakley Sound Systems does not provide direct e-mail support for Oakley projects, but is usually available via the forum.
