Welcome to the Oakley Modular page, home of the Oakley Modular System since 1999. All modules have been designed by Tony Allgood of Oakley Sound Systems and are available to purchase from Krisp1 via this website. All modules are available in our ready made format or as bare printed circuit boards for you to construct yourself.
Our full size modules are primarily designed for the 5U module system as originally defined by the Synthtech MOTM modular. As such they are fully compatible with MOTM and other MOTM compatible modules. They are also very suitable for fitting in Synthesizers.com systems. If you are building them yourself you can, with a bit of imagination, get them to work with the smaller formats too.
Our Compact 3U range is designed for Euro sized modulars and Fractional Rack systems. They are designed to work on either +/-12V or +/-15V. We are hoping to develop many more modules in this range in the next couple of years.
For technical support on all Oakley projects please now 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 support for Oakley projects, but is usually available via the forum.
