The Free Download

A free download of the core CDP-Wishart programs for sound transformation has been a big step for us. There have been more than a terabyte of downloads since it began. This software has been evolving for over 30 years. The free download is made possible by the commitment and generosity of all involved with the evolution and running of CDP.

This is particularly true of Trevor Wishart, the creative composer-programmer whose ideas and programming have been at the heart of the expanding software facilities since the 1990's, of Richard Dobson, who has been the key figure in maintaining the software and compiling it for distribution, of Archer Endrich who has spent years working with the programmers to document the software, and of Robert Fraser, who has been developing the Soundshaper GUI for two decades and has recently revised the documentation for the HTML5 and PDF formats.
