Dear CDP users,

We are getting an increasing number of queries about the new Apple M1 machines (ARM architecture).  At the moment we cannot compile for the M1 and request help from the CDP Community.  In the first place, we do not have an M1 machine nor the resources to purchase one (free software has its drawbacks).  Secondly, the SoundLoom GUI is written in TCL/TK using v8.5 and there appear to be various support problems for M1 that concern SoundLoom.

Ways to help:

 - Please let us know if you have successfully compiled the CDP code for the M1 and are able to use CDP with this processor and its related OS.  If so, would you be willing to share the expertise that has enabled you to do this.

 - Forward any information about TCL/TK and M1 support

 - Would someone be willing to try to compile CDP for M1 and correspond with Richard Dobson about how it goes (richard@rwdobson.com)

 - A final option would be to donate a spare M1 computer to CDP

We have been doing our best to keep up with the many OS changes that Apple have been making, but the M1 is so far a step too far for us.

Please respond to the Forum and/or directly to the CDP email address: cdpse9@gmail.com

Thanks very much,
CDP

I'm having the same issue, and would greatly appreciate any help to solve it!

The CDP Downloads page (hosted at https://www.unstablesound.net/cdp.html) 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:
 http://www.ensemble-software.net/CDPDocs/html/updates.htm 
- the full version is called CDPDocs.zip and is dated 30 Oct 2021. An update to this (to match the version on the downloads page) will be available in due course.

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]ensemble-software.net).

Within the online docs, the Guide is referenced on the Home Page (www.ensemble-software.net/CDPDocs/html/cdphome.htm) and the Tutorials page. The file cdpguide.zip 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.

The idiomatic way to do this is to use the shell scripting facilities. It is a good idea to read up on shell commands (and practice a little before committing to anything serious). Simple commands can be done directly at the prompt, but most of the time you will want to create a text file for your script. Here is an example to copy files to a named subdirectory:

#!/bin/bash
# usage  copyfiles.sh outdir
# copies wave files in current directory to same names in directory outdir
# outdir will be created if not present
# copysfx must be in system PATH

if [ -z $1 ]; then
  echo "usage: ./copyfiles.sh outdir"
  echo "outdir will be created if it does not exist."
  echo
  exit
fi

if [ $1 == "." ]; then
echo "can't copy files into same directory!"
echo
exit
fi

if [ ! -d $1 ]; then
    mkdir $1
fi

for filename in *.wav
do
   copysfx $filename $1/$filename
done
