The TEXTURE program currently supplied for PC systems is a pre-Release 8 version, which includes a new compulsory parameter ('omit') for the Texture Simple function.
Unfortunately this makes it incompatible with existing scripts in Textpack and Tutorial Workshop 2, as well as Soundshaper's Texture-Simple parameter page and presets.

It is expected that these settings will be updated for Release 8, but for now anyone wanting to explore Texture Simple on the PC needs a Release 7.1 version. You can download it at: https://www.soundshaper.net/downloads/texture71.zip .  Unzip and copy texture.exe into your existing CDP programs folder (...\_cdp\_cdprogs). If you want to retain the Rel.8 version, rename it (e.g. to textureR8.exe) before copying the replacement file.

SoundLoom (PC): to see if your version of SoundLoom supports the Release 8 version, go to the parameter page for TEXTURE SIMPLE; if that has provision for the OMIT parameter, then you don't need the older Rel7.1 version, otherwise you do. 

CDP MAC software and SoundLoom (MAC): not having a Mac, I don't know what the current situation is. However, you can check the Usage for Texture Simple to see if this includes the OMIT parameter and you can also look for it on the parameter page in SoundLoom (Mac).

Glad you got this working, but in general there can be a problem with some sound sources not having the "right" kind of header for CDP. Archer Endrich puts it like this:
"One problem that you may encounter is CDP not recognising an input soundfile when it has been made by some other software. This can be caused by non-standard anomalies in the wav header of the soundfile made by the other software. The problem can be rectified by making a CDP copy of this sound with CDP's COPYSFX. This can be run from the Command Line (copysfx infile.wav outfile.wav and see Usage for the various options), or via Soundshaper : Menu – Edit/Mix > SF UTILS > COPY. (COPYSFX is not available in a Soundloom menu.) "

As Simon suggested, run sfprops on the source file and see what it says about the header.  Normally CDP will retain the type (output=input), so I'm guessing the problem would have been with the source sound.

Hi OHT.

I recently found the Txpack examples were missing from the offline documentation, and fixed that via the online Tutorials page. As SimonK has pointed out, you can download a zip of the folder from there.  When unzipped, it should be placed as a subfolder of the \htmltuts folder in the offline documentation.

These examples are the ones discussed in the reference documents for the various Texture programs. Archer Endrich calls the texture events 'notes' and his examples mostly use a dry xylophone sound as the 'note'. The note-events are in fact any sound and can be played to the end or not, as you wish. I would start by investigating TEXTURE SIMPLE, then go on to GROUPED. Then look at ORNATE or DECORATE (they have variants PRE- and POST- ORNATE and DECORATE), or you might prefer TIMED (leading to TIMED GROUPS) or MOTIFS (leading to TIMED MOTIFS, the most prescribed one of the set.)

The tutorial Workshop 2 on Texture is more advanced and more detailed than Txpack.

They are both standalone programs - at least for Windows (not sure if there are MAC versions - I think not). There's also a new build of BrkEdit which should be released fairly soon.

A revised set of CDP programs for PC, re-compiled in 2022, is now available. The set comprises CDP Release 7, 7,1 and 7.11.
The programs are available on the CDP downloads page (https://www.unstablesound.net/cdp.html - 'Software PC' link) and are mirrored on the Soundshaper downloads page (https:www.soundshaper.net/dloads.html). The set has all the programs required for both SoundLoom and Soundshaper, including the LoomDatapak extensions.

Both SoundLoom and Soundshaper have this latest version built into their new-user installation files, as do Soundshaper updates/upgrades. The separate download is therefore aimed at existing SoundLoom users who wish to update their CDP software.

>I do get a lot of errors saying that it can't find the dsp process , and or that a new version of CDP is coming out and the process can't be executed

Your screenshot shows a message which comes up when there's a CDP error. Some of these can be rather obscure, but they're mostly down to incorrect parameter settings. When they occur, they are beyond the scope of Soundshaper and derive from the underlying CDP software. Your settings of a frequency split at 500Hz should normally be OK. (I've just tested it with a stereo input, with no problems.) I'm not aware of specific problems with Accumulate; however, if you want to send me the details of the sound source and parameter values used, I'll be happy to look into it.

I'm sorry you've had the inconvenience of not being able to access the forthcoming CDP8 processes yet, but unfortunately CDP8 is not quite ready for general release. In a further release of Soundshaper (6.03), which should out any day now, menu items which lead to a CDP8 process have been disabled. (A tiny number of CD8 functions, which are implemented as modes of an existing process, may still generate the message you quote, however.)   

Regarding the tutorial - clearly these things are written at different times by different authors and the descriptions can unfortunately become a little outdated. The CDP Distort suite deals with wavesets (as described in the documentation and help screens) and it was felt that this menu title better reflected the waveset functions as a whole. We do try to keep the documentation up to date, though, and thank you for pointing out this discrepancy.

The revised CDP documentation has now been corrected and can be downloaded from the CDP downloads page at
   https://www.unstablesound.net/cdp.html
or alternatively from
   http://www.ensemble-software.net/CDPDocs/html/updates.htm
where a wider range of download options is available.
