Composers Desktop Project Forum

The forum is live, but very very slow. There is a discord channel with a much faster response time here: https://discord.gg/QmQuJKB

Some people on the forum with in-depth knowledge of CDP, however, aren't on the discord. Those people will likely see your post and reply, eventually.

Sorry to say, I've got nothing on your actual question.

I've been working on a sound algorithms library and a frontend for that library for about a year now. Here is the first beta version! It shouldn't be too hard to get it working on Mac or Linux at some point, but for now, I just have a Windows binary prepared.

I made all dependencies optional recently so this should be quite easy to build now. I imagine there are some bugs in terms of endianness that are hard for me to check, but little-endian systems should be able to hit compile and go.

If anyone is interested, the latest push of this has gpu based audio-pvoc converters. I haven't heavily tested it (or anything else) so it's probably unstable, but it's quite fast.

Thank you Peter, hopefully this will bring some new interest to this corner of the net.   

No idea on building CDP, but if you want to try building xcdp the prereqs are all made for Linux, so I can only assume it will be simpler there.

A month or two ago I was discussing with another CDP user the discontent we felt with the difficulty of building additional software on top of the CDP. The codebase is, frankly, a nightmare. It isn't extensible or maintainable, or even comprehensible. I figured I should try to fix that, so I'm working on an audio processing library that aims to maintain the spirit of the CDP, but with a modern codebase and in library form. I'm not aiming for a one-to-one recreation, but I am aiming to recreate a large majority of the existing functionality in a form that is greatly simplified by having an entire programming language (c++) to work with. The naming convention will be different but I'm planning to create a mapping between cdp names and my own so long time CDP users know where everything is.

Here's a link to the repo (name suggestions are welcome): https://github.com/loganmcbroom/XCDP

I haven't used cmake before so the build might be rough at the moment, but I'd like the library to be cross-platform and it seemed like the de-facto option for that. It's also a work in progress, but it works, and passing lambda functions into blur_blur instead of time-value files warms my heart. If you've wanted to mess around with the nuts and bolts of the CDP but were scared off by if(sloom) and dz->bigBufbuf[buf], I hope you'll check it out and write some processes of your own. If you want help building or anything really, I'm always around the discord: https://discord.gg/QmQuJKB

Thanks for the reply Richard, Simon relayed your answer to me while I was exiled. Setting initial phases to zero lead to fine results for me, but slightly different output compared to the CDP. It's possible the difference was instead in my rewrite of blur_blur, I'll have to investigate further. The algorithm source is appreciated. I'm sticking to my suboptimal PVOC for now, I'll trade a bit of speed for simplicity most days.

Looks awesome

I don't have any idea, but I am here for solidarity 

Here's a discord server for cdp chatting: https://discord.gg/QmQuJKB

I don't think anyone wants the forum to be open to unregistered posting but would making it viewable without logging in create spam?

The only thing I've seen that I'd really compare to cdp is supercollider which uses a mailing list based forum, viewable without login. They also have a slack group I think which would be an alright solution. I mentioned it previously but I think an irc channel would be a good way to go and I can't imagine anyone is opposed to one being opened.

I voted when the poll was made but it doesn't seem like anyone has any kind of initiative. Having the community quarantined to a difficult to locate private forum has stagnated the growth of interest in CDP and if nobody else is going to do anything to fix that I might as well try. We get what, a post every two weeks about how soundshaper has trouble setting up on macs? There's clearly people interested by the setup questions but there's no community so I think people get stuck trying to figure out how the hell soundloom works and move on to better user experiences.

If you think a mailing list is the right way to go then make it happen, though I feel like mailing lists are a bit of a relic. If nothing else making the forum readable to non users would be a good start.

Seeing that this forum has been extremely quiet lately I feel like this topic should be revived. If nobody has qualms about it I'll make a facebook group in a few days. Not everyone uses facebook but it seems like a maintainable and accessible solution.
