Ibniz chugin available soon
by Julien Saint-Martin 03 Feb '13

03 Feb '13

Hi all, I integrated Ibniz software (http://pelulamu.net/ibniz/) inside a chugin. First version is ready and I want to share it with you. I know the Spencer's github chugin reporsitory. Is it a good idea to put it in? If yes, I never used github before please tell me if there is something special to do. One other things, I work on linux so I did not updated the VisualC++ .dsp file. Can someone look at this once the project will be uploaded? For OSX I think it is ok because the makefile seems to be shared. Cheers, Ju

Musical Metacreation Weekend (MUME-WE-2013) - Call for Participation
by alex 21 Jan '13

21 Jan '13

Musical Metacreation Weekend (MUME-WE-2013) - Call for Participation ======================================================= Musical Metacreation Weekend (MUME-WE-2013) Sydney Design Lab, University of Sydney June 14th-16th 2013 http://www.metacreation.net/mumewe2013/ ======================================================= Musical Metacreation is a forum for the emerging community of people making software that autonomously generates music. It engages with science, design, technology, philosophy, culture and aesthetics. Following the 1st International Workshop on Musical Metacreation of October 2012 (MUME 2012: http://www.metacreation.net/mume2012/), we are happy to announce MUME-WE-2013 in Sydney, a weekend of concerts, installations, panels, demos and other music listening. ======================================================= *** Call for Contributions and Participation *** Contributions are invited that fit the MuMe themes, in any of the following categories: music composition and performance systems, generative sound installations, audio-visual documentation. Contributors are not required to attend in person, as long as their work can be easily run in their absence. MuMe 2013 is music-only, with no paper track. * Themes * Musical Metacreation is concerned with autonomy and agency in software that makes music. A precise definition of how these terms apply to music remains itself an active area of enquiry, and individual projects can make their own case for how they address these aspects of behaviour. MuMe accepts submissions in the form of: • Systems that compose and/or interpret music • Systems that improvise with human musicians • Generative sound installations • Composition based on artificial life and artificial intelligence • Systems that engage in creative search or enhance the search process using advanced computing methods * Composition and Performance Systems * Music generating software that is designed to generate music all or in part by itself, either in the context of original music composition, or interactive improvised music performance. Three music events will be held, providing three different contexts. Instrumental musicians will invited on the basis of successful contributions. - algorave: an electronic dance music event consisting entirely of generative music in a club environment. - instrumental improvisation: a concert of free improvised music in which instrumental musicians are paired with algorithmic software systems to perform duets. - composed/conceptual: an electroacoustic concert for work involving computer-composed (realtime or offline) musical elements. * Generative Sound Installations * Continuously running generative installations, ranging from full artworks to high-quality demos. No budget is available for the setup of installations, but we can provide computers, speakers and projectors, as well as a number of spaces to present works. This includes a computer lab (Macintosh), allowing for the presentation of distributed works. * Audio-Visual Documentation of MuMe Systems * Recordings of music-generating systems with additional film content. Producers of algorithmically generated music are invited to submit fixed works in video format, for presentation in a “continuous listening room” at the event, but also later on the web. The work should take the following form: the audio should be a standalone, professionally produced stereo track of up to 15 minutes in length. The video should be an additional layer synched to the audio, strictly for the purpose of describing and explaining the work. This could be a slideshow, an informative visualisation of the music or a film with subtitles. The video should be treated strictly as an explanatory element for listeners to gain a detailed understanding of the system, and not as an artistic element, whereas the audio should be considered the opposite. Submission format: minimum requirements, HD 1920x1080 Quicktime Movie, with 44.1Khz, 16-bit stereo audio. * Panel Sessions * Panel sessions will be by invite from amongst participating artists. Please indicate if you would be interested in participating in a panel session. Non-attendees may join in over Skype. * No Paper Submissions * Although MuMe also exists as a conference workshop, the MuMe Weekend will not have a paper track. However, the MuMe weekend will be flanked by three conferences that will be highly relevant to participants (see below). Please note that the MuMe committee is not formally connected to these conferences and has no influence on paper acceptance. * Submission Process * Please use the following online form for submission: https://docs.google.com/spreadsheet/viewform?formkey=dC1FdmU1ZW1tQU1RajRGSn… Submissions will pass through a peer-review process and a curatorial panel process. The ultimate decision will lie with the organising committee and guest curators. Selection will be based on: relevance to the MuMe themes, technical quality, artistic quality, practicality (in terms of tech requirements etc.). Please note that contributors are not required to attend the event as long as their works can easily be set up and run without them being present. * Important Dates * Expressions of interest (optional, but we would appreciate it if you contact us if you intend to submit): ASAP Submission deadline: February 8th, 2013 Notification: March 8th, 2013 MuMe Weekend: June 14th-16th, 2013 Other events happening in Sydney in June 2013: • the International Conference on Computational Creativity (ICCC) http://www.computationalcreativity.net/iccc2013/ • Vivid Festival of Light, Music and Ideas http://www.vividsydney.com/ • the ACM Creativity and Cognition Conference (C&C) http://cc13.creativityandcognition.com/ • the International Symposium on Electronic Arts (ISEA) http://www.isea2013.org/ ======================================================= *** Organising Committee *** Oliver Bown (Design Lab, University of Sydney) Philippe Pasquier (School of Interactive Arts and Technologies, Simon Fraser University) Arne Eigenfeldt (School for the Contemporary Arts, Simon Fraser University) *** Curatorial Committee *** George Lewis (Department of Music, Columbia University) Alex McLean (Interdisciplinary Centre for Scientific Research in Music, University of Leeds) Michael Young (Department of Music, Goldsmiths College, University of London) Tim Blackwell (Department of Computing, Goldsmiths College, University of London) Jon McCormack (Centre for Electronic Media Art, Monash University) Juha van ‘t Zelfde (Viral Radio founder, curator Bimhuis, Musiekgebouw, Amsterdam) Ivan Zavada (Conservatorium of Music, University of Sydney) Aengus Martin (Faculty of Engineering, University of Sydney) Bill Hsu (School of IT, San Francisco State University) Please direct all enquiries to Oliver Bown (oliver.bown(a)sydney.edu.au).

Polyphony/Multiple Instruments in ChucK
by Curtis Ullerich 20 Jan '13

20 Jan '13

Hello, In my experiments with ChucK I've reached the point of wanting to use multiple instruments in polyphony (two Moogs in this case). My example is on GitHub here<https://github.com/curtisullerich/computer-music/blob/d37a98cb4f7b237b1791b…> . My usage pattern feels awkward and not very clean, and I'm hoping someone else has encountered the same situation. My question: What is a good way to manage and use multiple instruments in ChucK? It seems like a simple thing to want to do, but I haven't found any examples in the doc that work this way. Am I completely backwards about how I want to accomplish polyphony? My particular use case is made most awkward because I'm using an ADSR envelope. I think it's mostly ChucK's style of time tracking/advancement that's derailing me. If I'm not describing this well enough, please let me know. Any advice is appreciated. Thanks! Curtis

C function integration problem into a chugin
by Julien Saint-Martin 12 Jan '13

12 Jan '13

Hi all, I am currently trying to create a chugin with IBNIZ http://pelulamu.net/ibniz/ (it generate weird and loud sound, take care of your ears, headphones and speakers if you try it!!). My target is to only have sound from it. Ibniz source code is C, so I added the C file defining the functions I want to reuse inside the chugin make file: C_MODULES=vm_slow.c I call 3 of these functions inside the code generated by chuginate script: ibniz class defined in ibniz.cpp (chugin cpp source file) Compilation seems ok except 2 warnings: ~/Chuck/chugins/ibniz$ make clean; make linux rm -rf vm_slow.o ibniz.o ibniz.chug gcc -D__LINUX_ALSA__ -I../chuck/include/ -fPIC -O3 -c -o vm_slow.o vm_slow.c g++ -D__LINUX_ALSA__ -I../chuck/include/ -fPIC -O3 -c -o ibniz.o ibniz.cpp In file included from ibniz.h:12:0, from ibniz.cpp:15: vm.h:46:3: warning: anonymous type with no linkage used to declare variable '<anonymous struct> vm' with linkage [enabled by default] ibniz.cpp: In constructor 'ibniz::ibniz(double)': ibniz.cpp:45:24: warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings] gcc -shared -lstdc++ -o ibniz.chug vm_slow.o ibniz.o Then I perform the: sudo make install And the problem occurs when I try to launch a test.ck file [test.ck]:line(1): undefined type 'ibniz'... [test.ck]:line(1): ... in declaration ... I added verbose option 3 to check what goes wrong and I found that my ibniz.chug is not loaded cause of the following error: [chuck]:(3:SEVERE): | | error loading chugin 'ibniz.chug', skipping [chuck]:(3:SEVERE): | | error from chuck_dl: '/usr/lib/chuck/ibniz.chug: undefined symbol: _Z6vm_runv' vm_run() is one of the C functions I call in the chugin cpp file. So I suppose _Z6vm_runv is linked to it. As a test, I tried to remove all these C functions and the chugin is loading and running. So I think I made something wrong to integrate these functions correctly inside the chugin code. Any idea? What is chuck_dl? Thanks for your help. Ju

Dealing with String objects?
by Wolfgang Gil 09 Jan '13

09 Jan '13

Hello chuckers I am looking for a reference to the 'string' object class in chuck. I am having a hard time trying to guess what methods are available for the class. I also recently came across with the StringTokenizer object but it seems to work only when the token is a white space. Is it possible to assign a different token to the object? here is what I am working on UGen uArray[3]; new SinOsc @=> uArray[0]; new TriOsc @=> uArray[1]; new PulseOsc @=> uArray[2]; for(0 => int i; i < 3; i++) { <<<getType(uArray[i].toString())>>>; now + 1::second => now; } What gets printed is the object's type plus what I believe is a reference to memory that I am currently not interested in, separated by a colon ( TriOsc:1001f36a0) Happy holidays! -- http://www.wolfganggil.com <http://www.wolfganggil.com/about>

allpass filter/delay

Hello ChucKers, I got lost for several hours recently reading Sean Costello's The Halls of Valhalla blog http://valhalladsp.wordpress.com/2011/01/21/reverbs-diffusion-allpass-delay… I can't help but think that if I could figure out the notation of say Moorer's Figure 2.30 above to the point where I might translate into higher level ChucK delays, gains, and filters I could get lost for several hours making strange reverbs in Chuck instead. Can anyone help me get started? Thanks, michael

LiSa question
by Aurélien Bondis 10 Dec '12

10 Dec '12

Hi, I'm trying to figure out how to have multiple samples of different sizes looping together. I think I kind of have it but would like to be sure :) Are the voices here for that? Record does not have a voice option, so I understand that I have to explicitly tell my sample what part of it is supposed to be 'voice 1' or 'voice 2'. Also in my code, I seem to have my voice2 starting from something like 1second before its end and then loop, did I miss something ? Here is my code: --------------------------------------------------------- //a simple signal path adc => LiSa saveme => dac; //gotta tell LiSa how much memory to allocate 60::second => saveme.duration; saveme.recRamp(200::ms); <<< "recording 1" >>>; 1::second => now; 1 => saveme.record; 3::second => now; 0 => saveme.record; // Set voice 1 start and stop to use in the loop saveme.loopStart(1, 0::second); saveme.loopEnd(1, 3::second); <<< "recording 2" >>>; 1::second => now; 1 => saveme.record; 10::second => now; 0 => saveme.record; // Set voice 2 start and stop to use in the loop saveme.loopStart(2, 3::second); saveme.loopEnd(2, 13::second); // set voice 1 to loop saveme.loop(1,1); // set voice 2 to loop saveme.loop(2,1); <<< "playing">>>; // play loops saveme.play(1,1); saveme.play(2,1); while (true) { 1::second => now; } ------------------------------------------------------------ Thanks for your help.

Anyway, put it like this... the LiSa-track example files are working fine for me in Chuck 1.2.1.3 (on Windows 7 machine), but with 1.3.1.3 I'm just getting silence. Thanks Simon

I'm new to this program and list, but I have searched through the archives without finding a similar problem. Whenever I try opening a .ck file, i get this error message "[filename]: no such file or directory". So it recognizes chuck, but it seems like chuck just doesn't recognize .ck files as its own. I have Windows 7, 64bit. Maybe Chuck isn't compatible with this system yet? Your help is greatly appreciated. daniel

module chugen
by Michael Heuer 30 Nov '12

30 Nov '12

I knew I was going to get to this eventually; I have always wanted to be able to ChucK a ugen to a parameter, similar to control voltages in modular synths I suppose. With this public class Module extends Chugen { Gain _cv; { _cv => blackhole; } fun float tick(float in) { return tick(in, _cv.last()); } // subclasses override this function fun float tick(float in, float cv) { return in; } } I can do this, which interpolates the cv to a frequency between 2.0 and 8.0 class SinModule extends Module { SinOsc sin; { sin => blackhole; } fun float tick(float in, float cv) { Interpolate.linear(cv, -1.0, 1.0, 2.0, 8.0) => sin.freq; return sin.last(); } } and then this, which uses a SinOsc at a frequency of 0.25 as the cv to modulate the frequency of the SinModule which modulates the gain for a tremolo effect. class TremoloModule extends Module { SinModule gainLfo; SinOsc rateLfo; { 1.0 => gainLfo.sin.gain; gainLfo => _cv; 0.25 => rateLfo.freq; 1.0 => rateLfo.gain; rateLfo => gainLfo._cv; } fun float tick(float in, float cv) { Interpolate.linear(cv, -1.0, 1.0, 0.0, 1.0) => gain; return in; } } SinOsc sin => TremoloModule trem => dac; 0.4 => sin.gain; 220.0 => sin.freq; 1::hour => now; https://github.com/heuermh/lick/blob/master/examples/moduleExample.ck I am wondering if others have cleaner ways of doing this, because this example isn't even easy for me to follow. michael

OSC function crashing Chuck?
by Simon Steptoe 25 Nov '12

25 Nov '12

Whilst working on some OSC stuff, I got to a situation where Chuck (and mini-Audicle) kept crashing at the end of the main shred. I've stripped out all the Ugens and synthesis stuff and am left with the following algorithm (see below) as the culprit. At the end of the 5 seconds duration of the main shred, Chuck crashes. Take out "oeGetProcessId => now;" and all is fine. Now aside from whether it's a viable/good piece of code or not, I was surprised that it goes so far as to crash the system. Is it a bug... or is it me? (Code below). Simon Steptoe //CODE ============================================== OscRecv RecvProcess; 32000 => RecvProcess.port; RecvProcess.listen(); RecvProcess.event("/process/id, i " ) @=> OscEvent @ oeGetProcessId; Shred oscProcess; spork ~ oscProcessingIt() @=> oscProcess; 5::second => now; fun int oscProcessingIt() { int testValue; while (true) { oeGetProcessId => now; if( oeGetProcessId.nextMsg() != 0) { oeGetProcessId.getInt() => testValue; <<<"Hello from PROCESSING: ",testValue>>>; } 0.1::second => now; } } //============================================ Thanks Simon Steptoe

OSC

Hi List, I'm totally new in the Chuck world! I'm trying to use the OSC examples provided at http://chuck.cs.princeton.edu/doc/examples/osc/ and both chuck OSC_send.ck OSC_receive.ck and chuck s.ck r.ck don't work on machine. In the first case, OSC_send.ck seems to send correctly the OSC messages (it returns sent (via OSC): 0.895094 ...) but OSC_receive.ck never get them. r.ck runs the sine wave oscillator fine but never receive the messages sent by s.ck. I didn't make any change to the files (except for the path to the audio file in OSC_receive.ck, of course ;) ). I tried to send OSC messages to both OSC_receive.ck and r.ck with SuperCollider and PureData without any success. OSC works fine to communicate inside and between these two programs though. Am I missing some flags/options? I'm running chuck on Ubuntu 12.04 64bits. Thanks a lot for your help! Cheers, Romain
