We have been using this wonderful software for our sonic transformation and compositional work for the last twenty years. Unstablesound is excited to host this evolutionary phase for the CDP, available now for PC and Mac and Linux

'CDP's objective when it started in 1987 was to provide in-depth sound transformation software tools at an affordable price. We at CDP believe that it now follows a natural evolution for us to move into a public domain online culture and make our main software package a free download.'

The latest free version Release 7 is  released under a full LGPL Public Licence

Please go to the CDP page to download

A new online CDP User Forum is now available where you may exchange information, tips and ideas, troubleshoot, share your experiences of using the CDP software.
CDP also aim to promote 3rd party development via the forum.
