My system path reads as: %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\ATI Technologies\ATI Control Panel;C:\Program Files\QuickTime\QTSystem\ This includes %\System32, so Chuck should be in the system path, I believe. My Chuck folder with bin, examples, and doc are all located in D:\Chuck. I use the start -> run -> cmd shell. When I enter "chuck --help" it loads all the chuck info, so I believe it's running fine. When I prompt to D:\Chuck\examples and enter "chuck otf_07.ck" or "chuck otf_07" though, it gives me "[otf_07(or.ck)]: no such file or directory." This happens when I attempt to load any file in this way. All the example files register in "Dir D:\Chuck\examples", so I'm stumped.

What are steps you took to do this? - which shell are you using? via start->run... then 'cmd'? - what error message are you seeing? > I'm running Windows XP, and using the win32.exe ChucK (which I put in > System32). That's correct also. This should put chuck into your system path. After which you should be able to invoke chuck from any directory, using the command line interface. It may be that chuck.exe is still not in your PATH, it is inconceivable that c:\windows\system32\ is not in PATH, but still possible. Can you check which directories are in your path? You can do this right click on my computer (I think) and select properties, and under one of the tabs should be the default path - all the directories listed will be searched when invoking a program globally. Let's get this resolved! Let me know how things go. Ge! > I'm just trying out ChucK for the first time, and I'm not able to get > chuck to load a file.

A Bug? or is it a Feature?
by Mike McGonagle 24 Jan '06

24 Jan '06

Hello all, I was playing with some ChucK code that I wrote, and in copying some of the code to another file, I inadvertantly copied a global variable definition so that it was after a function that referenced that global variable. When I ran the code, I didn't get a message from ChucK that the variable was not defined when the code was compiled, and when the program ran, it would hang at the location where the global was referenced. (I don't have access at the moment to a running "ChucK", so I can only give an simple example.) fun void mySporkedFunction(float p1, float p2) { <<< p1, p2 >>>; globalVariable * 2 => float myLocalVariable; // do some sort of time function here } // define the global here 10.0 => float globalVariable; spork ~ mySporkedFunction(0.0, 1.0); When I ran my actual code, Chuck would hang up at the point where the globalVariable was referenced, in this example, that would be the second line off mySporkedFunction. The previous "print" statement would not output anything, until I hit Control-C to stop everything. Needless to say, I moved the global defintion to before the function, but I would think that there should be some sort of error message generated, or this should work as expected. Thanks, Mike

Question about Networking
by Mike McGonagle 23 Jan '06

23 Jan '06

I was working on some code in ChucK, and was thinking that it would be nice to be able to use an interface that I already have created using Pure Data. But, in order to do this, there would have to be something available that would be similar to either a MIDI event, or the like. Am I correct in understand that the "netin" and "netout" Unit Generators are specifically for transfering audio over the network? Are there any plans to create such an Event class? I would think something like this couldn't be written in ChucK, as there would need to be some sort of networking primitive to handle the connections and data transfer. How does Audicle connect up to ChucK? Is that purely through a commandline, with Audicle sending other commandline messages to a running "ChucK"? Thanks, Mike -- Help the Environment, Plant a Bush back in Texas!

about "dac/adc" to control input/out??
by Lewis Liu 23 Jan '06

23 Jan '06

Dear Sir, In my PC, there are two audio interface. One is the default in motehr board (SoundMax). Another is USB dungo. I can use --dacx and --adcx to force the audio input and ouput in SoundMax. But I can not use --dacx or --adcx to force the input in USB dungo. I do not know what is wrong. The codes are as follows: adc => gain g => blackhole; float x; while( true ) { g.last() => x; if( std.fabs(x) >= .05 ){ <<< x, "hello" >>>; } 1::samp => now; } Best Regards Lewis

Is there any "Community" repositories yet?
by Mike McGonagle 20 Jan '06

20 Jan '06

Hello all, I spent this last weekend working on a piece using ChucK, and quite frankly, it was something that I had implemented using PD, but was never really able to get one part to work successfully (probably more due to a design flaw or something). But, I was very happy to say that, using ChucK, I not only got the basic parts to work, but I also got the part that I was having trouble with in PD. I am very impressed with ChucK. So, basically, I would like to start posting some of these things to get some feedback from others, as well as some critiques of both the programming as well as the resulting music/sound construction. Is there a part of the WIKI that can be accessed by regular users to post some things? Or should I just post something to the list here (as an attachment)? Thanks, Mike

byte ordering and sndbuf
by Robert Edge 19 Jan '06

19 Jan '06

hey there, just getting started playing with chuck. I downloaded ChuckJoy.zip from the developers list and noticed that sndbuf was (not)byte-swapping the .raw files. converting the samples to little-endian solved the problem. .wav and .aiff files work fine, I was just wondering if this is what is supposed to be happening, as all the rawwaves that come with STK are saved in the same format. using chuck 1.2.0.4 on Fedora Core 3, amd x86_64 __________________________________________________ Do You Yahoo!?

winxp ChucK setup
by Julian Sorrel 18 Jan '06

18 Jan '06

I'm just trying out ChucK for the first time, and I'm not able to get chuck to load a file. If I prompt to D:\Chuck\examples\, theoretically I should be able to enter "chuck otf_01.ck" and have it launch, right? I'm running Windows XP, and using the win32.exe ChucK (which I put in System32). I'd appreciate any help. Thanks, Newb. --------------------------------- Yahoo! Photos Got holiday prints?

standard library documentation updated
by Ge Wang 17 Jan '06

17 Jan '06

Greetings, We have updated the online documentation for the standard libraries, finally adding descriptions to many functions: http://chuck.cs.princeton.edu/doc/program/stdlib.html The changes will also be reflected in the next version of the ChucK manual (pdf). All items on this guide should be present, with the exception of math.pi, math.twopi, and math.e. Please let us know if you find any problems. Best, Ge!

Question about Gain and instantiating objects
by Mike McGonagle 16 Jan '06

16 Jan '06

Hello All, I have created an object that basically is a simple sine wave grain to be used to create a "cloud" of sound. What I would like to do is to instatiate MANY of these objects, each of which would "exist" for maybe 10 milliseconds, or thereabouts. I was hoping to do this, as I am not really sure exactly how many instances will be needed at a given time. So, I got the object created (in the file 'sinegrain.ck'), and I call its function, sporking it into its own thread. When I create a single object, everything seems to work fine, but when I do more than one, everything goes haywire. I have attached an archive with all the files I use, and you can run them with the following... > chuck sinegrain sgtest1 rec-auto > chuck sinegrain sgtest2 rec-auto > chuck sinegrain sgtest3 rec-auto > chuck sinegrain sgtest4 rec-auto Each of the test files (sgtest...) creates the number of objects that is indicated by the number in the file name. When you run this, you will need to hit control-c to stop everything. The object will produce a print out with the gain of each generator, and once it is finished, it will print "done". You can hit control-c after that... I did this in Pure Data, but I had to create it in such a way that there were already all the generators instantiated, so if there ever occured a moment where one more generator was needed that created, it would "steal" a generator. This occasionally produced some clicks in the resulting sound. Will I need to create an "array" of my objects, creating all the instances that I may need? Or should I be able to create an object, call its function, and call its function by sporking it, and then instatiate a new object using the same object reference? I hope this makes sense, I didn't get much sleep last night, and my brain hurts... Mike
