ChucK on Intel Mac
by Eric Gilbert 31 Mar '06

31 Mar '06

Hi, I just tried to build ChucK on my MacBook Pro. It did not build. Is there some executable out there for intel macs? Or a tweak to the source or the build process? Thanks, Eric -- "Tyranny is tyranny, let it come from whom it may." -- Revolutionary conscripts, 1776

Class Libraries, File Naming Conventions, and 'machine.add(...)'
by Mike McGonagle 30 Mar '06

30 Mar '06

Wow, Since the release of 1.2.0.5, I have been working with miniAudicle, and I really like what I see so far (up to this point, I had been using the commandline version of ChucK). So, I am not sure if there is a separate email list for the miniAudicle, or if I should send the email here, or to the Audicle list... so... One thing that I am trying to do is set up my Class Libraries in a fashion where I point miniAudicle to the root directory, and I put my stuff into a directory structure as follows: Package/ClassLibrary/Make.ck Where 'Package' represents a folder of my libraries, 'ClassLibrary' is the name of the particular library, and the 'Make.ck' file is used to load the individual library files in the order needed by calling 'machine.add(...)' on each of the files. In doing this, I was hoping to be able to enter the following in my program file so that the Mask library gets loaded: machine.add("mjm/Mask/Make.ck"); So, this works when I have just this line in a file, and all the class files get loaded in the proper order. BUT, once I put any additional code into this file, it will not load the class files at all (and this was after restarting the miniAudicle to ensure that there wasn't any conflict with previously loaded classes). Here are the issues that I see so far... (1) Would it be possible to allow for miniAudicle to have multiple paths that it would search for finding these libraries? (2) Am I using 'machine.add(...)' for its intended purpose (in loading classes)? Might there be a good reason to add another 'machine.load(...)' that does the same thing as 'add', except it does not spork a new shread for each call? This 'load' function could also be made to keep track of what files have been loaded, and any time there is a file that gets loaded more than once, any subsequent loads could just be ignored? (This might also change the miniAudicle interfact to include a button to load, in addition to the other buttons.) Would this function be best named 'load'/'include'/'import'? Which one? (3) Any thoughts on why the classes do not load when I have subsequent code in my program (after the 'machine.add')? I could send you an example of what I am trying to do, but this would require sending out my libraries, and I would prefer to sent those out as archives so that the directory structure is maintained.

Fwd: [chuck] version 1.2.0.5 released
by Mike McGonagle 28 Mar '06

28 Mar '06

WoHoo!!! Yeah, AlRight... Cool Man... I can't wait to test drive... (Actually, Ge, thanks for sending me that "prerelease" version, I was able to test those things that I needed for the Fractal stuff I am working on.... Now, I guess this means, I actually have to post my stuff now...) WooHOO!!! Yeah!! Thanks to everyone who has worked on this fantastic piece of software!

Getting the keys for an associative array
by Mike McGonagle 22 Mar '06

22 Mar '06

Is there a way to get all the keys that are used as indices into an associative array? I was wondering if this is something that is in the works, or is it already available? I was thinking something like... ************* Object myAssociativeArray[0]; new Object @=> myAssociativeArray["first"]; new Object @=> myAssociativeArray["second"]; myAssociativeArray.keys => string keysList[]; for(0 => int i; i < keysList.cap(); i++) { <<< () => myAssociativeArray[keysList[i]].printObject >>>; } ************* Also, would there be a way of ensuring some sort of order inwhich the keys are returned (ie, the order inwhich they were added to the array???)?

Converting dB to chuck .gain
by Graham Percival 09 Mar '06

09 Mar '06

What is chuck's .gain measured in? Neither std.dbtorms() nor std.dbtopow() seem to work... I have a bunch of data about a sound, (frequency, dB): 86.132812, 9.996495, 172.265625, 6.996109, 258.398438, -0.955794, 344.531250, -11.900859, ... and I'd like to try some additive synthesis in chuck. The first value (frequency) is obvious, but I'm at a loss as to what to do with the second value (dB). What's the conversion factor between dB and .gain ? Cheers, - Graham

setDelay too big !

hi list i have some crash with this patch with this output: [chuck](via STK): DelayA: setDelay(1856.88) too big! i tried to debug, routing my signal without the PitchShift and/or without the JCRev, but it crashes anyway i guess it's because of the JCRev unit or perhaps it's because of my use of manipulating time, which could be not really academic... here's the patch Sitar s => PitShift sh => JCRev r => dac; //init rev, gains 0.9 => r.mix; 0.6 => s.gain; 0.5 => sh.gain; //lfo pitchShift freq sinosc shFreq => blackhole; 1.0 => shFreq.freq; //init sitar freq 280 => float temp; while (true){ 1.0 => s.noteOn; //variation pitchShifting (shFreq.last() * 10 ) => sh.shift; std.rand2f(0.0, 0.8) => sh.mix; (std.randf() * 20) +=> temp; temp => s.freq; 10::ms => now; }

hi thanks for hints and links about sound technique i'm running chuck "dracuuulaaa" on an ubuntu breezy with an ingo molnar's realtime patched 2.6.15 kernel (finally after a painful way...%] ) i've much better results regarding latency (my jack server runs with a buffer of 2x256 frames) than the build-in kernel ones. > Hi, > > I just ran the patch for 10 minutes without it crashing.

fm?
by eun.sung＠no-log.org 08 Mar '06

08 Mar '06

hi list i try to play around the fm unit generator and i can't make it work although i can use class depending on the FM class (TubeBell for example). this simple code make my jack server break out : FM f => dac; 400.0 => f.freq; while(true){ 1.0 => f.noteOn; 10::ms => now; } does anyone had already met some trouble with this class?
