Composers Desktop Project Forum

Thank you Robert Fraser. really appreciate it. I havent checked yet but does this leave sound thread out of the picture? this is a different topic  gonna check out these GUIs first. has anyone installed this on a ESP32 or ras pie and use it like a guitar pedal effects processor?

CDP PC INSTALLATION
The PC downloads no longer have an installer exe (since 29th August), as there is really no need for one.

There are two versions of the PC download: CDP8_001_PC.zip and CDP8_001Lite_PC.zip. (The Lite version just omits the offline CDP documentation, which is available online.)

Each zip contains a folder "CDPR8" and some supporting docs. Unzip and place the CDPR8 folder in a location of your choice (but not one that has spaces in the path, e.g. NOT in "Program Files"). You can rename CDPR8 if you wish. That's all.

CDPR8 contains two UIs - Soundloom and Soundshaper. (Soundthread is not included yet, as it's in active development.) The CDP programs are housed in CDPR8\_cdp\_cdprogs. Soundloom expects to find them there; Soundshaper looks there initially, but its settings can support a different location. Soundthread also needs to know where they are. Any use of the command-line processor would also need this path. 

Hello everybbody for some reason none of the zip files have the install exe for cdp.. Am i doing something wrong? I am thinking about compiling the source code

in the zip file there is a folder, 3 pdf's and a txt file.
 the gui exe's are in the folder but no cdp exe

please help thank you

Thanks for pointing out this discrepancy. I can confirm that the upper limit for PVOC points (the -c flag) is indeed 16380. Non-powers-of-two are not precluded, although pow-2 sizes are always the most efficient and fast. We'll look into the possibility of raising the upper limit, at least to 16384 or maybe 32768. In the meantime the online documentation will be corrected. (Offline generally lags behind, as it means changing the distributed packages.) 

There is an error in the documentation for pvoc anal https://www.composersdesktop.com/docs/html/cpvocman.htm#USAGEANAL

It states that the maximum number of analysis points is 32768 however the process doesn't allow for values higher than 12380.

QuoteERROR: INCORRECT USE
ERROR: Parameter[1] Value (32768.000000) out of range (2.000000 to 16380.000000)

Also interestingly the documentation states that values must be a power of 2 which is standard for fft analysis and true for almost all values however, 16380 is not a power of 2; 2^14 is 16384. Although the process does run fine with 16380 as the parameter value despite this.

Have you installed the updates listed here:

There is a fix for the filter banks getting stuck in that update

Hello! I can't seem to get any of the filter bank processes to work on my sound files. In the "dice demo" there's an example sound file that the subharmonic series filter bank is applied to. If I download that example sound file and apply the subharmonic series filter bank, it works. If I apply a filter bank to any other sound file I have, it does not work. All my sound files are already in mono, if that matters. I even changed the sample rate of my sound file to be the same as the one from the "dice demo" to see if it would work. I can't see any different between my files and the "dice demo" file.

When I run the command line, it reads this:

0 min  0.00 secINFO: Assessing input level.
INFO: Assessing output level.
INFO: Running filter.

And it stays like that with no completion.

Quote from: Algorix on August 22, 2025, 08:07:44 AMI'm reading the code, so I'm asking how it is possible that it is detected as a trojan virus by some AV softwares. Apparently there is no internet logic in that code, so am I crazy? I'm very skeptical in general so I'm not going to install this until a solution has been found.

Malwarebytes detects it as a trojan for instance, same for microsoft defender (those are the 2 I scan with usually)

A little update: to this day, Microsoft defender doesn't find malware anymore, while Malwarebytes still has some issues with it.

Following reports of potential viruses in the PC distribution, the whole CDP program set has been put through an online checker (Jotti.org) which sends files to 13 virus scanners, including all the well-known ones. Only three files caused any problems, with just two scanners: two of those are not user-level programs (just used internally by Soundloom) and the third is a long-standing and unaltered utility. 

We are sure these were false positives; however, we've substituted slightly earlier builds that passed the scanners' tests. So we can say with confidence that all the contents of the _cdprogs folder and all other supplied exes have been passed by 13 virus checkers and have not been found to contain viruses. We will continue to ensure that any further code revisions are similarly virus-checked. However, all software and files are supplied "as is", so users should always satisfy themselves about the integrity of the download.

There were also concerns about the use of an installer exe. For PC, CDP now supplies a plain zip file containing the folder CDPR8, which you simply place in any desired location (with no spaces in the path, so not in "Program Files", for example) and can rename as you wish.  For MAC, the installation has always been via a disk image file (dmg) and this is continuing. 

Hello! Really want to give this a go. Am familiar with false positives from AV products...(I think to resolve that on a per-product basis you have to report it to each vendor).  But - why not provide hashes or gpg sigs? : )
