General Board / Downloads Page: CDP documentation
« on: November 14, 2021, 01:23:46 PM »
The CDP Downloads page (hosted at is currently undergoing revision.

The CDP Documentation download, in particular, is faulty and should NOT be downloaded yet. It will be fully revised very soon and I'll post a notice when it's ready.

If you do not have the current documentation, it can be downloaded at: 
- the full version is called and is dated 30 Oct 2021. An update to this (to match the version on the downloads page) will be available in due course.

Announce / CDP GUIDE
« on: October 04, 2021, 07:56:12 PM »
A new set of documents called "CDP Guide" has been added to the online CDP Docs and is also available to download. This is a classified guide, which aims to help users find their way around the CDP suite. Although the Reference Documentation also groups functions together, it has become harder with each new release to keep track of related functions, especially as new versions or variations typically have different names.

CDP Guide classifies CDP processes and functions into five categories: Soundfile, Spectral, Pitch-Data, Edit-Mix (incl. Levels, Channels & Spatial) and Other  (Synth, Info, Data, SysUtils). Each function has hyperlinks to the available online Reference and a brief description. This is a personal classification and the descriptions are my own - they do not necessarily reflect the views of CDP. I'm sure there will be inaccuracies, and users are welcome to suggest corrections and amendments (mail[at]

Within the online docs, the Guide is referenced on the Home Page ( and the Tutorials page. The file is available from there or the downloads page (follow DOCS DOWNLOADS on the Home Page index panel). The zip also contains printable PDFs. If you already have the CDP documentation offline, the main folder \guide should be placed at the top level within that (the same level as \html, \demo etc.) for the hyperlinks to work.

PC Installation / Folder and file names in Soundshaper
« on: May 13, 2021, 02:59:17 PM »
It has been found that source files will not load in Soundshaper if "special characters" are used in folder names. The problem arose when a user installed CDP and Soundshaper in a folder called "Aplicações", which is Portuguese for "Applications".

Users should stick to Roman-alphabet characters (as used in English) when naming folders and files, i.e.: a-z (lower or upper case) and numbers 0-9.

PC Installation / 'Run as Administrator' issues
« on: October 17, 2020, 10:17:03 AM »
I recently bought a new PC with Windows 10 and had some fun (?) with administrator problems. I already had a version of Soundshaper on a disk I'd transferred from the old computer, and also imported a new build from another PC to the C drive. Neither would run or even close down as they weren't allowed to over-write various textfiles: "access is denied"!

The solution seems to be to tick a box called "Run as administrator". You have to create a shortcut to the .exe, right-click on the shortcut icon for its "properties", then from the pre-selected Shortcut tab choose Advanced, then tick "Run as administrator". This works, but produces an annoying User Account Control window every time you run the program.

Somehow I've created two shortcuts for the new version: one has "Run as administrator" and opens with the User Account Control (and fails otherwise), but the other (on the desktop) starts perfectly without "Run as administrator" being selected.

If anyone can explain this conundrum, I'd be grateful.

Announce / Soundshaper 5.07 released
« on: May 09, 2020, 03:06:13 PM »
A new version of Soundshaper (5.07, 9 May 2020) is now available for download. This version fixes an Access Violation affecting TEXTURE processes and revises the Initial Setup and reading of the Settings file, which will be renamed automatically.

Version 5.06 (3 May) fixed a significant bug affecting processes with more than 10 parameters, including TEXTURE and GRAIN.

Announce / CDP Documentation Updated
« on: April 03, 2020, 09:49:55 PM »
The CDP documentation has been updated today (3rd Apr 2020). The online html docs were already the latest, as were the individual printable pdf versions, but the zip files of both were out-of-date (Aug 2018). Now corrected, with apologies for any inconvenience. The docs are housed at

Two changes I would appreciate some help with: SFEDIT ISOLATE in cgroedit.htm has apparently been updated but to my eye it seems the same as in the unchanged sfedit.pdf. Similarly PAPLAY in cmcrefmn.htm / mctoolkit.pdf. Let me know if you can spot any difference(s) :) .

Announce / Soundshaper 5: support for Csound
« on: April 30, 2019, 09:13:40 PM »
The latest Soundshaper update (5.03) adds support for running Csound scripts, as well as users' own Batch scripts. The Csound scripts can either be for synthesis, writing to an output file, or for sound processing, with one or more input files. (Real-time output is not supported at present.)

The inputs and outputs are integrated within Soundshaper patches (process chains), i.e. a Csound process can precede or follow a CDP process, and the overall patch can be saved and recalled. Taken together, CDP and Csound cover a vast range of audio processes and a huge number of Csound examples are readily available, particularly for synthesis, which by comparison is a bit thin within CDP.

The update also includes Csound's implementation of Paulstretch (extreme time-stretching), hard-coded as a "normal" process with parameter control. I will be looking for other opcodes and scripts that would be worth integrating in this way and would welcome any suggestions and feedback.

Announce / Soundshaper 5 released
« on: March 01, 2019, 10:54:11 AM »
Soundshaper 5.0 (beta) has now been released. This version has important new features designed to improve workflow:
 - built-in streaming player/viewer, with extensive provision for editing and processing part of the sound
 - multi-layer patches: patches extended to multiple layers. Embed a patch within a patch; save and load this as a single object within a patch and so on
 - revised Process List: supports user-saved parameter settings (single presets) for rapid recall of favourite processes
 - improved file-saving
 - re-designed Main Page: clearer layout and menus. Support for many new skinned styles.

Soundshaper 5 (PC only, Vista-Win10) can be downloaded from .

Announce / Soundshaper 4.5.05 released
« on: March 12, 2018, 12:04:53 PM »
A new version for Soundshaper (4.5.05) has now been released for Windows. All users are recommended to download this version, which is available as an update to an existing 4.5, an upgrade to a previous installation of 4.4, or as a full version.

The Mix Page has been extensively revised and repaired in this version. CDP mixes are very versatile, especially for relatively short sounds and the revised page aims to make them as easy to manipulate as possible. A revised Soundshaper HTML reference for the Mix Page is also available for download and is included as a .PDF in the upgrade.

Quick-help documentation for all CDP processes has now been completed and is accessible from within Soundshaper. Other bugfixes repair a number of CDP functions that were not working.   

Announce / Soundshaper 4.5 released
« on: June 13, 2017, 09:26:14 PM »
A new version of the Soundshaper interface (4.5) is now available ( This introduces the new Cell-Patch feature, in which an existing patch can be run within one cell. A patch containing one or more of these sub-patches can be saved and re-run as normal.  (Full details are in the supplied Release Notes.)

Parameter Files (.prm) can now be dropped onto the Main-Page patchgrid. This opens a parameter page with the appropriate parameters and values, so it's a quick way of selecting and running a preset. Parameter files are simple text files which can be saved from a parameter page (as 'snapshots') and are also produced as temporary files in the normal course of running Soundshaper.

Announce / CDP Documentation available as printable PDFs
« on: April 04, 2017, 06:45:20 PM »
The CDP reference documentation (excluding tutorials) has now been converted into printable PDF format and can be accessed here:

This page has links to download the PDF docs as well as the HTML docs as zip files, and also to view individual PDFs online. There is a link to the online HTML docs, which is also duplicated in the menu (CDP > Online Documentation > CDP Docs Home Page).

(Various charts and a couple of papers were already online as PDFs and are included within the HTML zip.)

Announce / Revised CDP Documentation Online
« on: August 27, 2016, 05:06:19 PM »
The CDP documention has been revised and a provisional version can be accessed online at:
or you can start here:

Most of the original text has been retained, but the structure and links have hopefully been improved.

You can download the docs as a zip (for PC - 66MB). First, rename your existing docs folder (\cdpr7\docs) to e.g. \docsold (to avoid a garbled mixture of old and new docs). Then extract the zip to your CDP base folder (\cdpr7). The link is:

The aim will be to keep the latest set of docs online and make it possible for users to update individual pages as required. A list of recent updates is available at!Updates.txt and future updated files will be accessible from .

The new docs have not yet been added to the CDP distribution, so now is a good time to email me your suggestions (rob[at] As there is now one set of docs for both PC and Mac, Mac users in particular can help by pointing out anything that is not correct for that platform. 

Improving the documentation is a continuous process and the next steps will be to create printable .pdf versions of the reference sections, as well as make more playable examples available online.

Robert, Documentation Co-ordinator. 

Announce / Soundshaper 4.4.1 released
« on: December 22, 2015, 08:57:03 PM »
A revised Soundshaper (4.4.1) can be downloaded from:
Simply unpack and replace your existing Soundshaper.exe (4.4).

The new version (hopefully) fixes two scripting bugs. The first affected the following CDP functions -
 - if the second Infile had already been converted to its native type (.for / .frq / .trn), instead of being auto-converted from a .wav or .ana file by Soundshaper.

The second bug was a typo (an extra '+') that got written into the scripts. This affected:
These functions mostly generate pseudo-soundfiles for viewing.

Announce / Soundshaper now a free download
« on: September 11, 2015, 01:03:14 PM »
I am pleased to announce the release of Soundshaper 4.4 as a free download!

Much of the Soundshaper code has been re-written, including the batchfile scripts used to run CDP processes. Almost 100% of these now accept multi-channel as well as mono/stereo input and incorporate the automatic conversion of CDP file types wherever possible. Many more processes now support different parameter sets per channel.

For those not familiar with the program, Soundshaper is built around a multi-process patch grid, supporting up to 16 different processing streams. Soundshaper uses temporary files, so that it is not necessary to save files at every stage, only those you want to keep.  New in version 4.4 is not having to save source files with a patch, so that the patch saves a complete history of a processing sequence in a compact form. Patches are fully editable and can be run with different sources. The text History function has also been updated to record parameter values more clearly.

Also new in 4.4 is bulk processing, implemented as a copy-row variant. A few mouse clicks load a list of sources to the patch grid and apply them to a process or row of processes. Another new feature is a composite process called Premix: a sound is given a prefixed delay, level and pan, ready for CDP mix processes that don't use a mix file. The dedicated Mix page has also been overhauled, again with aim of making mixing easier.

Soundshaper Pro and Lite have been withdrawn. The new Soundshaper is technically still a Beta-test version, and bug reports would be welcome. E-mail support is still available for registered Pro users (only) and the registration mechanism has been retained to enable possible installation on a new computer. New registrations are not possible, however; this situation might change if CDP is willing to adopt paid support. Existing registered users can also try out the forthcoming Patch To Cell facility, due for general release in the next version.

Full details and downloads are available at A more detailed description of Soundshaper can be read here:

Announce / Soundshaper (4.4) Beta-test release
« on: June 14, 2015, 02:55:52 PM »
A new Beta-test version of Soundshaper (4.4) is now available from my website: The program has been extensively revised to write and run entirely new scripts, which incorporate automatic conversion of CDP file-types and are almost completely channel-independent (running with mono, stereo or multi-channel input). One of the goals behind the revisions is to be able to run a whole multi-process patch within one cell. (For non-Soundshaper users, a cell normally runs one process.) Though this feature is not fully coded yet, enough of it is working for users to try it out.

Registered users of Soundshaper (Pro) are encouraged to download and test-run the new version, and feed back bug reports (by e-mail please). The release is not a full distribution, but assumes you have version 4.3 (preferably 4.3.13) installed on the same machine. This allows for sharing of text files and presets and also for comparison between 4.4 and the last release, if something appears to have become broken.

Following testing, Soundshaper 4.4 will be released as unregistered freeware and Soundshaper Lite will be withdrawn. The new cell-patch feature is intended for version 4.5, but currently registered users will still be able to access it (as 4.5 Alpha or Beta) before 4.5 is released.
