Shred blocking main shred
by Gonzalo 28 Aug '18

28 Aug '18

Hi, I'm working on a big project (www.whole-play.com), tons of classes, tons of calculations happening at various points. My problem is that some of these calculations take too long, up to a few seconds. I thought if I run them in their own shred, the main shred would be unaffected, but it's not the case, and the music stops during those processes. Maybe I'm doing something wrong. I can't post sample code because it's many classes interacting, but I thought maybe someone has ideas on how to tackle this issue? Thanks! Gonzalo -- http://dense13.com http://www.whole-play.com

chuck 1.4.0.0, global keyword.
by Dana Batali 02 Aug '18

02 Aug '18

Hi all - I'm not sure if this is more of a developer question, but I'll try here first. I'm investigating integrating ChucK into a custom app and am intrigued by the new chunity integration. The key aspects of chunity (for my purposes) are the new global keyword coupled with the ability to send/recv values (and events) from a controlling application. I have two questions: 1. does the new global keyword actually work? In miniAudicle 1.4.0.0 (on windows), i have a one-line script: global int myvar; This produces an error message: [untitled]:line(1).char(33): syntax error which goes away with the removal of the global keyword. 1a. i do see a special branch of chuck called dac-ugen-replacement which may be hold the answers to my question. Perhaps it's only a matter of the windows build being a little behind (due to the grammar change)? 2. is there a github repository for the chunity plugin? I don't see it in the standard chuck github. It's possible that the global keyword is only activated for special builds of chuck and I might be able to get to the bottom of that question by inspecting the chunity builds. Incidentally, I see that ChucK Racks addressed a set of similar problems in a different manner (by extending the chuck environment directly via PluginHost). My impression is that these two activities occurred in parallel and that there may be an advantage in combining the two approaches, perhaps ultimately producing a publicly available .so/.dll as part of the chuck distribution. Advanced thanks for any comments or pointers on these questions! And the usual giant kudos to the ChucK devs for producing such a cool thing!. Regards, Dana Batali

ChucK on patchstorage.com
by Mario Buoninfante 25 Jul '18

25 Jul '18

Hi everybody, I got in contact with the guys at patchstorage.com, asking to add ChucK to the existing platforms, and they've been super kind and added it in a couple of days... so, now it's also possible to share ChucK scripts there! https://patchstorage.com/platform/chuck/ cheers, Mario

VSCode ChucK plugin now available
by Forrest Cahoon 14 Jul '18

14 Jul '18

Hi all! I just published an extension for Visual Studio Code which will do syntax highlighting for ChucK. It was a port of an Atom plugin, so I really didn't do that much work. If you use VSCode, you should be able to search marketplace extensions for "chuck" to install it. Forrest

Oscin addAddress query
by Scott Hewitt 06 Jul '18

06 Jul '18

Hi, I was moving some code away from using OscRecv and OscSend to make use of OscIn/OscOut and OscMsg. I found the versions file (under 1.3.4.0) useful in doing this. The example r.ck within the OSC examples was also useful. I did find something that I was unclear about though within it. What is the purpose of the if within line 15? 9: OscIn oin; 14: // create an address in the receiver 15: oin.addAddress( "/foo/notes, if" ); https://github.com/ccrma/chuck/blob/master/examples/osc/r.ck All the best Scott

Chugin/Faust issue
by mario buoninfante 20 Jun '18

20 Jun '18

Hi, I'm having issue with a chugin generated with faust2ck. I'm on a 64bit Linux machine (Ubuntu Studio 16.04) and I created a simple /sample and hold/ component in Faust (SampleAndHold.dsp that contains /declare name "SampleAndHold"//;/) and then turned it into a chugin using faust2ck. everything seems fine, my /SampleAndHold.chug/ is generated, but unfortunately I cannot use it in ChucK (console: /undefined type 'SampleAndHold'.../) . I copied it into the chugin folder and also tried launching ChucK with -gSampleAndHold . does anyone have any experience with faust2ck? am I missing something? cheers, Mario

Hi, in the next days the ChucK manual we'll be brought back to http://flossmanuals.net (there's always been a version there, in the meanwhile on the new platform we were updating a copy of it). as I reported here when I started working on it, at that time I've been asked to test a new platform for editing (https://omnibook.pro). now it looks like it's time to bring it back to the main site ;) FYI everyone can follow the discussion here: http://lists.flossmanuals.net/pipermail/discuss-flossmanuals.net/ I'll keep you posted. cheers, Mario

Sound glitches at the start of descending tones
by Forrest Cahoon 20 Jun '18

20 Jun '18

I'm attempting to play with descending tones, but I'm having artifacts at the beginning of the sound. I tried to start with a gain of 0 but this does not prevent the glitch. I've used various sorts of oscillators; when I use SinOsc there is just a glitch at the very beginning of the sound, but with SqrOsc and others there is what sounds sort of like LFO amplitude modulation for maybe even a second into the sound. Here is my code. How do I fix this? SqrOsc r => dac; // also try SinOsc, TriOsc, and SawOsc 300.0 => float STARTING_FREQ; 10000 => int OCTAVE_STEPS; for (0 => int i; i < OCTAVE_STEPS ; i++) { // making an envelope by manipulating the gain if (i < 100) { i * 0.005 => r.gain; } else if (i > OCTAVE_STEPS - 100) { (OCTAVE_STEPS - i) * 0.005 => r.gain; } else { 0.5 => r.gain; } // constantly falling frequency if (i == 0) { STARTING_FREQ => r.freq; } else { STARTING_FREQ * Math.pow(2.0, -1.0 * Math.log2((1.0*i)/(1.0*OCTAVE_STEPS))) => r.freq; } 1::ms => now; }
