Announce / Soundshaper 6
« Last post by Robert Fraser on September 09, 2022, 04:33:05 PM »
Soundshaper 6 has now been released.  This is a major upgrade, designed to improve workflow.

The main changes are to the parameter page, which now has a preview facility, allowing the user to quickly experiment with and compare many different parameter settings before choosing one. It also has a soundfile display, mirroring that on the Main Page, with loop and marker times that can be transferred to and from breakpoint data files. There is a tighter integration with the Graph-Edit page, which also has a soundfile display. Full details of the new features are supplied with the program, and the manual has also been revised.

To download the program, please visit
General Board / Re: Changing WORKSPACE Location in Sound Loom

Hello, I would have the same question, but updated for the present day on a MAC machine?
I have "set directory for CDP programs" in the Sound Loom, but it does not change the workspace location...

I think I have isolated the problem trying different variations in paths, trying to eliminate various possibilities. As far as I can see, the problem for me is that if the outfile is a path greater than or equal to 6 directories deep it fails. In this case it just ouptuts the first slice. For example when these are paths for outfile;

/Users/seanodalaigh/Documents/composition/2022/ - - - > this works fine

/Users/seanodalaigh/Documents/composition/2022/BLUE/ - - - > this fails (it is invariant to the CAPS)

I wonder if anyone can reproduce this?

Thanks ,

Thanks Simon and Richard!

Sorry for my delay I thought the problem was elsewhere, but I think I have isolated it now as I described.

running this is successful and produces the 15 audio files I am expecting

seanodalaigh$ sfedit cutmany 1 /Users/seanodalaigh/columbia.wav /Users/seanodalaigh/sylabble_ /Users/seanodalaigh/breakpoints.txt 0.01

If I move the files (columbia.wav and breakpoints.txt) to a my intended folder and run it; something like (with paths line separated here only for ease)

seanodalaigh$ sfedit cutmany 1

it outputs the first grain only. This seems to be an error statement that follows when this happens

0 min  0.00 secAbort trap: 6

I am assuming (hoping) I have the enviornmental variables set up correctly, as many other processes work fine for me in any folder structure. I actually tried making arbitrary folders in the Home directory to test it and it works actually! Maybe there is something in the strings of the paths I am supplying that is causing a bug?

Thanks in advance for the help,

I have tested this with the same OS version (and both 2016 build and the latest build) and not been able to reproduce the problem. It would be helpful to have example command lines and data file to reproduce as closely as possible. Test reports from other users would be welcome too!

Hi Seán,
Welcome to the forum & thank you for the complimentary remarks.

As a seasoned user I expect that you'll have set the environmental variables and so have a working, in every other way, system.
In which case this would seem to be a bug.
I'll alert Richard to this, thanks for the heads up.

Hello all,

I have been using CDP for a number of years now but have only just joined to forum. Nice to digitally meet you all!

I had a question re. SFEDIT CUTMANY. When using it in on the command line, (Mac OS 10.14.6) and specifying an output directory that is not the Home directory, it only writes one output slice from a potential many. If I write the output in the Home directory however it successfully writes multiple files. Just wondering if this is expected behaviour, or maybe I am doing something incorrectly?
Thanks in advance, and thanks also to the CDP team for such an amazing and inspiring set of programs!

General Board / CDP and M1
« Last post by ArcherCDP on March 18, 2022, 12:30:15 PM »
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 (

 - 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:

Thanks very much,
