Announcing Csoundo

in Library and Tool Development • 3 years ago

I'm happy to announce the first ALPHA release of Csoundo, a Processing library for Csound. Csound is a high-end music & audio synthesis language.

Download Csoundo

Csoundo is in very early development, but like they say, release early and often. Csoundo has only been tested on OS X Leopard and Snow Leopard. It comes with three examples: A mouse theremin, f-table-to-graph and a

visualization experiment. Video of the last example can be seen here.

A special thanks to everyone in the Csound community who has been helping me figure out the Csound API to make Csoundo a reality.

I just uploaded Csoundo 0.1.2 Alpha. It should run on a few more systems. Here's the rundown:

-Eight examples are included in this new release that demonstrate: a
simple slider GUI, creating score events, channel busses, reading and
writing to f-tables, generating graphs from tables, syncing audio with
animation and playing a Csound composition.

-The README.txt has been upgraded to include better install
instructions for Linux, OS X and Windows.

-This release should work on a few more computers, as audio now
outputs to the default DAC, where as before, it would sometimes try to
render to a file on some computers.

-Users can also now set the Csound command-line options with the
cs.setOptions() method.

-A few things have been cleaned under the hood, which should provide
better stability.

i think you forgot to include csnd.jar in the zip file

also using the csnd.jar from the old version i now get this error when running an example:

_jcsound native code library failed to load.
java.lang.UnsatisfiedLinkError: no _jcsound in java.library.path

have i forgotten to install something?.... do i need to original csound installed?

I actually accidentally included it in the last version. Which worked great for people using OS X.

Though the csnd.jar varies, I believe, from platform to platform. So I put a note in the README.txt about making a copy or a symlink to the csnd.jar, which ships with Csound. Though as I'm reading it now, I could have been a little bit more clear. Well, at least the docs will be better for the next release.

What version are you using? If you are on OS X, you can find the correct csnd.jar here. If that doesn't work, let me know.

/Library/Frameworks/CsoundLib.framework/Resources/Java/csnd.jar

im on win7 but do i understand you correctly that i need to download and install the original csound?

jacobjoaq..

Re: Announcing Csoundo

Yes, you definitely have to install the original Csound. The csnd.jar is just an interface to Csound and its libraries. Distributing Csound with Csoundo isn't really feasible for a few reasons, that's why it's done this way.

Re: Re: Announcing Csoundo

ok downloaded and installed it and then copied csnd.jar to the lib folder but i am still getting:

_jcsound native code library failed to load.
java.lang.UnsatisfiedLinkError: no _jcsound in java.library.path

I wish I had a windows machine. The only thing I can think of is to reboot Processing if you haven't. I'm looking into the problem.

Truth be told, Csound is a bit fickle in setting up. Once it is, it's generally really stable. One of the biggest hurdles I have in making Csoundo a worthwhile library is to make sure that Csound and Csoundo are easily setup. I'll probably create install scripts or a utility that will do this down the road.

A quick update: It may be java paths problem. That's what I'm checking up on.

Re: Re: Announcing Csoundo

hmm this is.. strange
well i added C:\Program Files (x86)\Csound\bin to the CLASSPATH entry in my system variables and now i can get the sketch to run only to have a new error thrown at me:

NoSuchMethodError: You may be using a library that's incompatible with this version of processing

Exception in thread "Animation Thread" java.lang.NoSuchMethodError: csnd.Csound.TableGet(II)F

Re: Announcing Csoundo

That is weird. Which sketch are you trying to run? Which version of Csound? Which version of Processing?

And thanks for taking the time to try this out. I love getting bug reports, so that I may fix things.

sketch: the table example (but i get this error for all examples)
version of csound: 5.11
version of processing: 1.2.1

Re: Announcing Csoundo

Could you try sketch playMessage example? That's the most basic example of the lot.

bjordal

Re: Re: Announcing Csoundo

playMessage makes JAVA platform binary crash... (wtf)

however the example called "events" works! so does headerInfo if i remove everything inside draw
edit: "random" also works

jacobjoaq..

Re: Announcing Csoundo

That's something. I'm actually not too surprised that playMessage didn't work. The quick explanation is that the control rate (krate) is set to 44100. I've had issues where setting the control rate to the sample rate crashes the system when used with visuals. This example works on my system, though no visuals are generated, but is still a problem.

It seems the issues may lie with reading and writing to tables. If this is the case, then examples chnInOut, experiment_1, headerInfo and sliders would work.

Or it could be very well that Csound isn't fully started when the first frame is drawn.

Re: Announcing Csoundo

only the ones i mentioned works also experiment_1 crashes the java platform

edit: experiment_1 runs for like 1 second and then crashes... wtf

edit2: chnInOut works if i remove all calls to cs.getChn()

Re: Announcing Csoundo

It seems out of the ones that do run, control rate is set much lower. If you're up to it, you can try setting the rates yourself. For example, open up experiment_1.csd in the data folder of the example of the same name and replace:

kr = 441
ksmps = 100

with:

kr = 1470
ksmps = 30

playMessage may actually be the best example to try this with. I'm thinking that some of the problems may be that your system is being overloaded. I'm on a multi-core machine, and it may be that Csound is running on one core, while Processing is running on another. Just a guess at this point. I'll know more once I hear from others.

Re: Re: Announcing Csoundo

replacing with

kr = 1470
ksmps = 30

however i tried replacing it with:

kr = 44100
ksmps = 1

and then it worked only it didn't play any sounds....
i am also on a multicore system...

Re: Announcing Csoundo

Well, I certainly have my work cut out for me. Thanks for the great feedback, as I have much more to go on. I may have to invest into a copy of windows. I'll see if others are having these issues, and will hopefully get back to you. I really want this one figured out by next release. Let me know if you have any more luck, good or bad.

Thanks!

@bjordal

The problem may be that you are running the doubles version of Csound. Try this download instead:

http://sourceforge.net/projects/csound/files/csound5/csound5.11/Csound5.11.1-gnu-win32-f.exe/download

Re: Announcing Csoundo

I was curious, so I tried to (Windows XP Pro SP3, Processing 1.2.1). Downloaded 2nd version of Csoundo and installed it. Ran Processing, Java 1.6.0_21 although Processing uses my 0_18 SDK).
Ah, I have Csound 5.8 archive but hadn't installed it yet. Did that. With a path without spaces, I avoid them with command line utilities and libraries, sometime they are senstive...
Ran the playMessage sketch, it complained because csnd.jar wasn't there. Doh!
Found it in Csound\interfaces\java, copied it next to csoundo.jar. Ran playMessage, complained about a native library.
I check, the Csound/bin have been added to the path. Ah, but Processing was started before install.
Closed and re-opened Processing, ran the sketch. It works!
Well, sort of. For the record, here is the output:

csoundo 0.1.2 by Jacob Joaquin http://csoundblog.com

The playing is a bit choppy, and very sensitive to CPU activity (I have an old computer!): if I do page down in Firefox, I have a sound glitch!
When I close the sketch's window, I have all output from Csound displayed at once... and a message showing a crash of JVM!

Tried drawTables, got: Exception in thread "Animation Thread" java.lang.NoSuchMethodError: csnd.Csound.TableGet(II)F

experiment_1 works, but sound is really too choppy. I will try again when I get a modern computer... Still a JVM crash when stopping the sketch.

Re: Re: Announcing Csoundo

Thanks for reporting this back. It may just be that Csoundo won't work with Csoundo 5.11. Csound 5.12 for Windows should be released in the next couple of weeks. In the mean time, I'll continue to look for answers.

I also get the following error:

_jcsound native code library failed to load.
java.lang.UnsatisfiedLinkError: no _jcsound in java.library.path

Is there a fix for this yet?

Edit:
I am running Csoundo 0.1.2 (and have also tried the double version) with Csound 5.12 on a 64-bit Mac (OS X 10.6.5).

Re: Announcing Csoundo

Could anyone tell me why I keep getting NULLPOINTEREXCEPTION with the line cs.run(); ? I have csound 5.11 float (I cant find a 5.12 float executable ??) and csnd.jar is in the library folder with csoundo.jar.

Any thoughts? I really want this library to work.

Thanks

ps heres the full code from the chnInOut example...
