Ah, this is an example of one of the many hearts of the CDP system. In a GUI-based effect or instrument, this would involve controlling a rotary knob or a slider. Here in the command line we use a "breakpoint file". The simplest of these is by far the most common. It is a text file containing one or more lines, each with two numeric entries (separated by a space). The first is the time in seconds, and the second value is the required parameter value. The only rules are that (naturally) the first time value must be zero, and subsequent times must always increase. The file is then saved to a name of your choice. By CDP convention, the file extension is "brk", but "txt" is fine too. On the command line, where you would otherwise type an umber for a given parameter, you use the file name instead. The programs handle this internally, kn owing to lookm for either a single number or a file name.

So, a simple example might be:

0.0 1
0.5 2
2.3 4.5
2.4 3.9
3.0 1.1

From which you can gather that the programs will interpolate linearly from the stated values to generate all required intermediate values. Thus, if you just need a plain linear ramp 1->10 from start to end, for a 5-second sound, all you would need is:

0.0 1
5.0 10

Just adding that I've also just run into this issue, no idea how to find a workaround as this post is the only evidence I can find of others encountering the problem.

Any updates dBFS? Anyone else able to shed some light here?

Thanks!

Hi,

I am currently exploring the nice wavesets suite of functions, and in particular I was testing 'distort interpolate' when I notice that the parameter
multiplier may vary over time

How is this achieved from the command line? (I am using Mac OS X 13.6.8, if that's relevant, but I suspect it's not.)

Thanks much for your help!

hello again
i fixed the onedrive problem. turns out i just needed to put everything onto an external harddisc and delete onedrive. Soundshaper works now too, so you where probably right about it being stored in the cloud being the root of the problem.

thanks a lot for the help, and patience!

Hi, In many programs, you can save content to different file types. For example in Paint, you can save the image as a jpeg, bmp etc.  Soundshaper doesn't as yet do this sort of conversion when saving (exporting)  files. So if the output type is .wav you should select .wav as the file type, if .ana, select .ana and so on.  The message you quote comes up only if you're trying to save the output file to a different type. This applies to saving via the standard Windows selector and the SAVE box on the left. The output cell is colour-coded to help with file-types: white for wav soundfiles, aqua for spectral freq. files (.ana), mauve for pitch-data files (.frq), green for formant file (.for), red for binary envelope files (.evl), plus a few others. 

There is one exception to the above, though. If Option 5 ("Auto-FFT ana-wav") is set (and I think it normally should be), spectral output (ana files) are auto-converted to .wav for play and display purposes (although aqua for ana is still the cell-box colour). You can therefore select .wav as the output file-type to save to. Soundshaper does have a range of auto-conversions and maybe more should be applied when saving (I'll look into this), but some are not technically possible anyway, e.g. .for to .wav. It would be clearer if the file-types listed for saving could be narrowed to show only the relevant ones and I'll look into that for the next update.

You're welcome to send me any screenshots if this doesn't help. I'm not clear what you're referring to when you "open up windows to do processing it looks well out of whack" - maybe a screenshot would help here.

Hi, just trying to export sounds from Soundshaper and I'm getting an error message saying 'Saving to a different file type not possible'. As well, when I open up windows to do processing it looks well out of whack. Processing works fine, but nothing I make will export.

I'm running Windows 11 with a fresh CDP install, and I saw elsewhere on the forum someone else was having issues with Soundshaper and it was narrowed down to the .txt file in the \BIN folder - could that be what is happening here? If so where can I get a fresh .txt file from?

Sorry, I can't seem to attach screen shots for some reason, but can email them through if you need!

Thanks so much for your help!

When trying to launch Soundloom, I get following error:

Fatal Error in Wish
System Encoding

I think this is because my OS is cyrillic.
I remember that Trevor Wishart had special executable file replacement that fixed it on his website, but from what I recall it was provided for very old (by now) version of SoundLoom.
Perhaps new one could be compiled and provided with recent release?

Thanks.

For those, who like me, still uses "legacy" version of Windows 10 and was slightly confused by explanations in Installation Notes for CDP.
As it's a bit different from how it is done in up to date versions of Windows 10 (and different from pre-win10 experience as well), steps are following...

In upper field you can see "Path" variable, choose it and click "edit...", then it opens a table of various paths, from there you choose "create..." and input C:\CDPR8\_cdp\_cdprogs (or what you have instead) and then confirm it.

Hi Aila,
There are some instructions here about unlinking OneDrive:
https://support.microsoft.com/en-gb/office/turn-off-disable-or-uninstall-onedrive-f32a17ce-3336-40fe-9c38-6efb09f944b0

I would suggest caution before tinkering with any Windows setup though! On my own machine, the link between its internal OneDrive folder and syncing this to the cloud got broken somehow and I'm happy to keep it that way, as I can still access the actual cloud OneDrive by signing in to my Microsoft account in a browser. I've no wish for all my junk files to be sent to the cloud and clog up my limited space there.

Previously, you seemed to have set your temp. folder within OneDrive and I really wouldn't recommend this. However, I can't say for sure that this is the root of your problem and it would still be helpful if you could send me one example of a file that won't load. There have been instances in the past where copysfx is not able to read the file and it's important that we can rule this out.

I had wondered initially that slow loading could be the issue, but on re-examining the code Soundshaper does check twice to see if the file is there - after a 1" delay, which is enormously long for a modern computer.

hello again,
after I read your previous message i've found out that my computer apperently stores everything automatically in Onedrive, including the folder i downloaded Soundshaper in. Im going to look into it next week.

im quite at a loss as to why it saves everything in Onedrive so if you've got any ideas how stop it i would greatly appreciate it, although i also understand that this isn't what this forum "is for"
