ChucK for live musicians
by joe higham 21 Dec '13

21 Dec '13

hi @ chuck-users lists I'm busy following the Coursera ChucK course provided by CAL Arts. As a live musician I was hoping to discover how one could use ChucK live (in the same way as Pure Data, Max/MSP etc). We've seen Ajay Kapur (whom I'm sure you all know) using his sitar in a live concert video made at CalArts, but no explanation followed. Unfortunately it seems that the course isn't going to cover this topic, so I've joined the list hoping people can help me out. Would it be possible to start giving me a few basic outlines for how to use ChucK via the adc (I'm a sax player). If you're interested (and if it works) here's a link to a thread created via CalArts and Coursera asking these questions: https://class.coursera.org/chuck101-001/forum/thread?thread_id=1429#post-77… You won't be able to comment but you will notice that we all wonder if one should pass via blackhole, if we should use a FFT etc. And more important, how? Thanks in advance Joe

Eclipse Plugin
by Alejandro Salas 15 Dec '13

15 Dec '13

Hello everyone, I don't know if this has been addressed elsewhere. I searched the archives and couldn't find anything. I was wondering if there was any initiative on creating a plugin for eclipse. I have some experience creating plugins for eclipse (although I haven't done any in a while), and I'm willing to help if necessary. Thanks.

No simple vibrato example
by Manuel Bärenz 05 Dec '13

05 Dec '13

Hi guys, I'm giving a presentation on ChucK tomorrow and I wanted to show off some of the basic features in a live coding session. I found that creating a vibrato (modulating the frequency) is far too hard. The example I'm looking at is http://chuck.cs.princeton.edu/doc/examples/basic/whirl.ck. In an infinite loop, you have this code: 30 + ( Math.sin(t) + 1.0 ) * 10000.0 => s.sfreq; t + .004 => t; Here, t is a float and s is a SinOsc. Now, what I would have expected is the following, more intuitive setup outside the loop: 30 + SinOsc freq_mod => s.freq; 1 => freq_mod.freq; I know that the first line with the "30 + SinOsc" is probably nonsense in itself, but I could work around that (by using a step UGen for example). My actual problem is that you can't chuck a SinOsc into s.freq. Consider this line: SinOsc freq_mod => s.freq; I get an error like this: arguments type(s) do not match: ... for function 'SinOsc.freq(...)' ... ...(please check the argument types) Is this something that the language is simply not capable of or am I doing something wrong? Best, Manuel

MIDI-synchronization and metric timing (?)
by Blixa Barscheck 05 Dec '13

05 Dec '13

Hi, ChucK-Community! My name is Steve. So far I have been using Max 6 for MIDI-programming. My primary workflow is that I generate MIDI-data in Max and send them to my DAW where it's used to trigger several SoftSynths. I am the point now, however, where Max doesn't offer me enough flexibility to realize what I want to do. I am considering switching to ChucK. There is one thing, however, I need to know about ChucK: In Max I am able to synchronize it's timing mechanism to my DAW and define any kind of timing data (e.g.: frequency of an LFOsc) in metric timing (1/16-notes, 1/8-notes, etc.). Is this also possible in ChucK? If no, then ChucK unfortunately is no option for me, at least at the moment. Thanks! best regards, steve -- Diese E-Mail wurde aus dem Sicherheitsverbund E-Mail made in Germany versendet: http://www.gmx.net/e-mail-made-in-germany

What does $ do?
by Gregorio Gomez 22 Nov '13

22 Nov '13

Hello, everybody: I've been looking at Michael Heuer's (most excellent) LiCK library. He uses an idiom that I don't see documented: intervals.get(i) $ Interval @=> Interval interval; from Arpeggiator.ck, line 35 https://github.com/heuermh/lick/blob/master/Arpeggiator.ck What does $ do? Of course just because I don't see it in the documentation doesn't mean it's not there, so please feel free to point me to the docs if I've overlooked it. Thanks! Greg

Problem with multiple audion sources
by monon＠att.net 20 Nov '13

20 Nov '13

I am a new chuck user and have just installed linux-alsa from source. All works well as long as there is no other audio source active. If there is another active audio source active I get this message when, for example, I type in chuck --loop: [chuck]: RtApiAlsa::getDeviceInfo: snd_pcm_open error for device (hw:0,0), Device or resource busy. This seems to be a chuck issue as I can run multiple audio sources as long as one of them is not chuck. My concern is that I started a coursera course on chuck and would like to use chuck concurrently with the course. My operating system is Kubuntu Linux 12.04. Does anyone have any ideas? Thank you, Monon

Hello ChucK linux users, We are excited to have a beta version of chuck that features PulseAudio support! While PulseAudio is not always ideal for professional audio usage, we absolutely recognize that its a popular choice for general-purpose Linux installations.

[MiniAudicle] Minor bug with editor
by Pierre Faure 11 Nov '13

11 Nov '13

Hi, I recently acquired a late 2013 Mac Book Pro running Mavericks. While working on MiniAudicle on this computer, I noticed a few problems, all bypassable, but annoying nonetheless. First of, while using non ascii characters, like ‘é’ in strings. I made a program that looks up samples, and their name is hardcoded in the script, e.g. « réso1.wav ». When I save the file for later use, and load it up again, the ‘é’ are gone, the editor displays « reso1.wav ». My files are therefore not accessed. I don’t think that is normal, as on my Windows PC, non ascii characters are accepted. Secondly, when I paste from the terminal (like a folder path), the editor uses whatever colors my terminal background is set in. I use black, so when I paste, the background of the pasted line becomes black. Lastly, here’s an error message I get from the console window. 2013-11-11 18:14:31.318 miniAudicle[662:707] *** WARNING: -[NSImage dissolveToPoint:fraction:] is deprecated in MacOSX 10.8 and later. Please use -[NSImage drawAtPoint:fromRect:operation:fraction:] instead. 2013-11-11 18:14:31.318 miniAudicle[662:707] *** WARNING: -[NSImage dissolveToPoint:fromRect:fraction:] is deprecated in MacOSX 10.8 and later. Please use -[NSImage drawAtPoint:fromRect:operation:fraction:] instead. Again, those are minor problems. Best regards, Pierre FAURE

Trouble with Machine.add() and paths on Windows; listing loaded shreds
by Gregorio Gomez 31 Oct '13

31 Oct '13

Hi, everybody: I'm new here. I'm really intrigued with ChucK and I'm looking forward to working with it. I am having one problem. I've taken a look at the list archives, and the forum, but the fixes I've seen there haven't worked for me. If there's something there that I overlooked, I apologize. Please feel free to point me in the right direction. Basically, I'm having some trouble including the LiCK library, but my questions are more about Machine's add() method. Here's an example of what's not working: Machine.add("c:\\Program Files (x86)\\ChucK\\libs\\lib-master\\BinaryFunction.ck"); And the errors: [chuck]: unrecognized escape sequence: \P [chuck]: malformed filename with argument list... My questions: When Machine.add's argument is a relative path like this: Machine.add("BinaryFunction.ck"); or this: Machine.add("libs/BinaryFunction.ck"); what's the path relative to? What's the correct way to use absolute paths in Windows? What's the correct delimiter for paths in Windows? Is it possible to get Machine to list loaded shreds? I'm running: Windows 7 miniAudicle 1.3.0 ChucK 1.3.2.0 Thanks! Greg

miniAudicle issue
by Morgan 28 Oct '13

28 Oct '13

Hi there, I am trying to get miniAudicle/chuck running on my reasonably fresh install of Linux mint KDE. I have a MB with onboard Audio which is what I have plugged up to my speakers and is set as the default audio device in my system settings.. My audio works smoothly for other things such as mp3, flac and orb playback, MIDI (suck as linux MM Studio). I do not have jack installed. I went through the process of installing all of the dependancies, compiling and making the installs, though i dont know if there was an order i was meant to do it in. I have been trying to trouble shoot... I have run from the terminal ~ > lspci | grep audio 0a:0c.0 Multimedia audio controller: Creative Labs SB Audigy (rev 04) ~ > chuck --version chuck version: 1.3.2.0 (chimera) linux (alsa) : 32-bit http://chuck.cs.princeton.edu/ http://chuck.stanford.edu/ On initializing miniAudicle the console reads - [chuck]:(2:SYSTEM): setting log level to: 10 (ALL!!)... [chuck]: RtApiAlsa::getDeviceInfo: snd_pcm_open error for device (hw:2,2), No such device. then when i click start virtual machine the program hangs up (whether or not I have a shred in the Audicle window.) Sometimes it will give me an error message about an infinite loop, even without any shreds? I am pretty stumped right now... i have been googling but cant find anyone have the same issue. Morgan

getting started questions
by Steve Morris 28 Oct '13

28 Oct '13

I'm new to ChucK but am very excited. I have grand plans. I will likely have lots of questions (some unfortunately stupid, apologies in advance) although I have been pouring through manuals, examples, the wiki, git source code and forum archives. Hopefully my questions won't be too annoying. I'm always happy to receive answers in the form of pointers to documentation I should be reading before wasting the groups time. Here's my first pass. 1) I can't find any thing that documents the scope of variables and objects. Can I create variables that can be accessed in other files, other threads. 2) My first project will be fairly large hopefully split between many files. Where can I look to see how ChucK code should be broken down and organized. What is a good paradigm for a shared library. 3) Speaking of libraries I would like to bring a lot of existing C++ code into my project. Does dynamic linking actually work. I see vague (old) references to it being made to work again as if it was broken and other references to it just needing documentation which will come "soon." Lacking documentation is there an example library that does it. I can get a long ways with a working example. Working code may be confusing and slow to understand but it is its own most accurate documentation. I've looked at chuck_dll and I think I need to see the interface from the other side to really understand. I'm happy to be a reviewer for "preliminary" draft documentation. 4) The Mac install seems to have installed a single bundled app. How do I use the command line interface? Thanks, -steve (aka zencuke)

Minor bug when saving an example with "save as."
by Steve Morris 27 Oct '13

27 Oct '13

Hi. I'm new to ChucK and love it so far but I would like to report what I think is a minor bug. I'm on a Mac running OSX 10.8.5. miniAudicle "about" reports: version 1.3.0 (gidora) Copyright (c) Spencer Salazar ChucK: version 1.3.2.0 (chimera) 64-bit Copyright (c) Ge Wang and Perry Cook http://chuck.cs.princeton.edu/ Bug report: Note: this is low priority and minor, more in the category of an annoyance. I opened an example then saved it with "save as." Then I edited it then tried to save the changes. A dialog reported the file was read only. I checked the file with info and the file has Read & Write permission. I can overwrite it with "Save As" but Save refuses to save. I suspect that the example was read only and it kept that attribute in some file state variable. If true this is wrong in two ways, first it should have updated the local state to match what it wrote and second it should not depend on historical information. Even if the file was read-only when opened that may have changed. This is a multitasking system and some other task (me in finder for example) might have changed the permissions since the file was opened. I believe the correct behavior would have been to attempt to write the file and check the error status of the write. Best regards and thanks for a wonderful tool. -Steve Morris aka zencuke > >

is 'string' a primitive type?
by Kiran O.V. 23 Oct '13

23 Oct '13

Hi When I click 'add shred' with the following code: public class A { static string a; } it throws following message: [*unnamed1]:line(3): cannot declare static non-primitive objects (yet)... [*unnamed1]:line(3): ...(hint: declare as ref (@) & initialize outside for now) as if string is non-primitive. And when I follow the suggestion and use a ref public class A { static string @ a; } it throws the following message: [*unnamed1]:line(3): cannot declare references (@) of primitive type 'string'... [*unnamed1]:line(3): ...(primitive types: 'int', 'float', 'time', 'dur') as if string is a primitive type. Is it a code limitation or am I doing something wrong? Thanks in advance! Kiran

turn off midi clock on osx
by Michael Heuer 15 Oct '13

15 Oct '13

Hello, I am using ChucK to send MIDI to a MeeBlip micro http://meeblip.com/use-one/assembly-guides-legacy-models/micro-kit-assembly/ through some cheap MIDI-over-USB device which uses a generic driver on OSX. Unfortunately the MeeBlip can't handle incoming MIDI clock/timing data and it seems to be receiving such even though I'm not sending any via ChucK. Is there a way to disable MIDI clock in ChucK, or in OSX, or both? Thank you, michael

All of those instruments contain noise. Likely a Noise object. Wonder if Noise itself does a seed? I'll check.

Apparently, the non-random bug does not happen after declaration of all STK instruments, just some of them: BlowBotl, BlowHole, Clarinet, Flute, Saxofony, StifKarp, VoicForm And the problem occurs with both Std.rand2 and Std.rand2f (I haven't conducted any more tests yet to see under what other conditions it might happen.) david > Forgive me if this was already discussed on the list before.

Non-random random number

Forgive me if this was already discussed on the list before. I am puzzled about a non-random random number. When the random number is calculated right after an STK instrument is declared, the result is not random. It is the same number every time. However, if the same code occurs without an STK declaration before it, the result is random. while (true) { StifKarp stu => dac; int randy; Std.rand2(0,10) => randy; <<<"here are three random numbers", Std.rand2(0,10), Std.rand2(0,10),Std.rand2(0,10), "and NON-random Randy", randy >>>; Std.rand2(0,10) => randy; <<<"here are three more random numbers", Std.rand2(0,10), Std.rand2(0,10),Std.rand2(0,10), "and random Randy", randy >>>; 1000::ms => now; } david David Loberg Code School of Music Western Michigan University 1903 W Michigan Ave Kalamazoo, MI 49008-5434 code(a)wmich.edu
