CDP Featured Composer Harry-Ed Roland has died

Eric Clark, a friend of Harry-Ed in Berlin, kindly phoned me on Wednesday evening to let us know that Harry-Ed Roland had just died. I present here a brief personal note while awaiting further information.

CDP: Software for Sound Design

• The art of designing sound has been at the core of contemporary composition innovation for at least 100 years. This takes many forms, such as highly inventive 'Foley' sound-effects, designing all kinds of new instruments, sound installations, the synthesis of sound by computer, and the transformation of recorded sound 'samples' by both analogue and digital means, as well as real-time improvisations on laptops.


• Already established in the fields of electronic and electroacoustic composition, sound design has become mainstream in film, computer games, animations, advertising, and songs.


• The CDP software, first released in 1987, now contains hundreds of ways to transform digitally sampled sound. Its software belongs to the musique concrète category, as realised on computer. Processing is off-line. Although the processing is often faster than real-time, several processes could not run in real-time for technical reasons.


• The CDP software can be run via one of the two available GUIs or via command line / batch file.


• Based in the UK, CDP is an international network of composers and programmers guided by a vision of amazing sonic possibilities and how they can be woven into the fabric of music. We have been working together since 1986. About CDP and its approach.

Donations/Sponsors Welcomed

The core CDP developers are working hard to re-imagine CDP in an online public domain context. Since free download, we are reliant on donations to maintain the organisation and the software. Please donate what you can when you can. Sponsors have the option to tie in with one or other specific project.

We would like to acknowledge donations from Arthur Green, Stephen Goldstein, Tom DeLio, Richard Dobson, Carlos Gonzales Bolaños and Gregorio Lozano Galan.

Featured Composer

Our current Featured Composer is Harry-Ed Roland, resident in Berlin and an imaginative CDP user for many years. His compositions that feature the use of CDP software are listed in Links to People and Music (scroll down to 'Harry-Ed Roland').

Online User Forum

A CDP online user forum has been set up by Simon Kunath. We hope that this forum will provide a means for users to ask questions about the software and get answers from other users. It also provides a way of reporting possible software bugs. Software updates will be posted periodically.

CDP Privacy Policy

In line with the new government directives coming into force on 25 May 2018, CDP has revised its Privacy Policy. The text explains that since the advent of the free downloads, CDP no longer maintains a database of users as it is impossible to do so. We do not send out 'mailshots'. The Privacy Policy document describes in detail how any personal information is held and used.
