Determining the address of an OSC message
by Brian Robison 06 Sep '20

06 Sep '20

Hello, ChucKers! I am looking for a way to receive an arbitrary OSC message and determine its address. In my toy example, my receiver will receive messages at /sndadj/lgain and /sndadj/rgain and adjust the gain of the L or R channel accordingly. Here's a program that would probably work if there were an OscEvent.address() function: SinOsc sl => dac.left; SinOsc sr => dac.right; 0.5 => sl.gain; 0.5 => sr.gain; 225 => float lfreq; 150 => float rfreq; lfreq => sl.freq; rfreq => sr.freq; OscRecv recv; 6449 => recv.port; recv.listen(); OscEvent oe; recv.event("/sndadj/lgain, f" ) @=> oe; recv.event("/sndadj/rgain, f" ) @=> oe; while (true) { oe => now; while (oe.nextMsg() != 0) { // XXX - OscEvent.address() doesn't exist if (oe.address() == "/sndadj/lgain") { oe.getFloat() => sl.gain; } else { oe.getFloat() => sr.gain; } } } I do have a version working with a single /sndadj/gain address which sends two floats, but it makes my sender uglier and I feel like address discernment is something ChucK probably does anyway. Any ideas? Thanks! Brian

Thanks Jack. I've had a quick scan of chuck global variables on the chunity tutorials and chuck-users list. Looking forward to embedding into a C++ app, and likewise for a JavaScript app. Thanks for the steer!

ofxChucK
by Mícheál Ó Catháin 26 Aug '20

Hi there! I stumbled upon Ge's ofxChuck page earlier today. I would be very interested in exploring this addon. My installation of OpenFrameworks is on a Raspberry Pi 4 however. The README.md is written with the XCode IDE in mind. I'm using Vim on my RPi, via ssh, though pixel desktop environment is also installed. Are there any reasons ofxChucK would not work as an addon to OF on a RPi 4? If anyone has done this and/or written a tutorial I'm all ears. Otherwise I'll endevour to write one myself if I get it going! micheal

Passing functions as arguments
by John Crane 26 Aug '20

26 Aug '20

Hi all, Chuck newbie here. Is it possible to pass a function as an argument? I'd like to be able to transform things in a functional programming manner. As a trivial example, if I had an array of midi notes and wanted to raise them all one interval. fun int increment(int note) { note + 1; } // use map to apply a function to all elements of an array map ( array_of_notes, increment); thanks in advance, John

Hi Jack, Thanks for clarifying! I'll try the workaround you suggest with global variables and report back!! Socket.io will be my first port of call for a JavaScript mechanism but open to all suggestions...

webchuck and osc
by Mícheál Ó Catháin 26 Aug '20

26 Aug '20

hi there, Webchuck is such an excellent development - thanks for all the work that has gone into this by Jack (and others I'm sure). Hopefully I'll be able to contribute in some way in future, after getting up the learning curve a bit more! I have a question about using OSC with webchuck... I have a .ck script running on my local machine, using OSC to emit messages every X samples of a .wav file played by a SndBuf. These OSC messages are received by a webpage on my local machine. For this receiver I am running the page using node.js, and... * https://github.com/automata/osc-web * socket.io Locally, this works fine - as I play the .wav file via ChucK on MiniAudicle, the webpage at localhost:3000 displays the OSC messages as I'd expect. However when I try to run this same .ck file using Webchuck, I get the following error message: chucknode.js:189 [osc-eibhlin.ck]:line(38): undefined type 'OscOut'... Does Webchuck feature OSC messages yet? Thanks Micheal

imports/includes
by Curtis Ullerich 19 Aug '20

19 Aug '20

What's the state of the art for imports/includes? If I have files lib0.ck and lib1.ck that declare public classes both used in control.ck, I understand these to be the two options for running them: chuck lib0.ck lib1.ck control.ck or, make another file control-main.ck: Machine.add("lib0.ck"); Machine.add("lib1.ck"); Machine.add("control.ck"); and run it as: chuck control-main.ck I thought it would work to use Machine.add("lib0.ck"); Machine.add("lib1.ck "); as the first line of control.ck and then just run chuck control.ck, but the included classes are not found. Are these the two options, or is there another way that can support transitive inclusion (not having to list each util file for every program that uses them)? Thanks, Curtis

Re: [chuck-users] imports/includes (Curtis Ullerich)
by Perry Cook 16 Aug '20

So if I understand you correctly, this is solved fairly easily by a structure we propose in the "ChucK Book” 1) Create a file that loads (by Machine.add()) all the classes you think you’ll need. 2) As the last line of that, have it Machine.add() a different file, which then either does the work, or adds any file(s) that depend on those initial classes. I’ve sometimes even named these files include.ck and Main.ck but include also runs Main, so it’s not strictly an “include” or import. Hope this helps, PRC

Error in Console
by Daniel Cooper 13 Aug '20

13 Aug '20

Hi everyone, This might seem like a very basic question, though I’m getting an error in the Console that makes it impossible for me to use MiniAudicle: “[chuck]: (DirectSound) error (Generic error) creating input buffer (Default Device)! [chuck]:(2:SYSTEM): | | | cannot initialize audio device (use --silent/-s for non-realtime)” I’ve tried everything I could find online, and it seems my audio drivers are working. The program worked just fine on my old computer, but I have no idea how to get around this on my new computer. Has anyone come across this before? I’m using version 1.4.0.1, Windows 10. Any help would be greatly appreciated! Cheers, Daniel

chuck.exe is infected!
by maria p cruz 09 Aug '20

09 Aug '20

Dear Ge Wang! Because this mail is "only for Ge Wang" nobody else must answer it! My Windows 10 legal copy was infected with your ChucK server download of the chuck.exe, can you please dear Ge Wang explain to me and to everybody else who uses Windows 10 why your chuck.exe download file contains malware (a troyan perhaps?)). PS: the screenshots "with the infection proof"are not attached, they are sent to Ge Wang CCRMA e-mail inbox. I hope Ge, You can solve this error because I cannot use ChucK on Windows 10 now. Maria
