cast dur to time?
by Kassen 07 Jan '08

07 Jan '08

Dear list (and language designers in particular), this is legal; now + 2::second => time later; so, we know that time and duration are quite similar things (we already knew that ourselves but now we know ChucK agrees). However, this isn't legal; 2::second $ time => time later; I tried this, intending "later" to refer to the moment 2 seconds after the VM sprang to life. Are there good reasons not to allow the casting from time to dur and dur to time? Yours, Kas.

caps lock state?
by dan trueman 07 Jan '08

07 Jan '08

am i wrong that you can't get the state of the caps-lock button? you can, with Hid, see whether it's gets pressed or released, but you can't tell what state it's in. dt

WORKSHOP: Introduction to the ChucK Music Programming Language, January 13th RSVP: Please RSVP for this event through the Bay Area Computer Music Technology Group at http://electronicmusic.meetup.com/152/calendar/6710874/ PRESENTED BY: Ge Wang (http://ccrma.stanford.edu/~ge/) TIME: Sunday January 13th, 2008 1:00-1:30pm: ChucK presentation (30min) 1:30pm-4:00: ChucK workshop LOCATION: CCRMA, Stanford University 660 Lomita Drive, Stanford, CA 94305 More information: http://ccrma.stanford.edu/~ge/knoll/ INTENDED AUDIENCES: composers, sound designers/researchers, laptop performers, programming language enthusiasts, and anyone else interested in programming computer music. participants are encouraged, but NOT required, to bring laptops (if you do bring one, OS X, Linux, Windows are all supported). No prior experience with ChucK expected. DESCRIPTION: ChucK is a continually evolving computer music language being jointly developed at Princeton University and now Stanford University (with Ge's joining CCRMA). It combines familiar programming language constructs with a new time-based concurrent programming model and the ability to write code on-the-fly. This workshop is a crash course in the philosophy and use of ChucK. The audience will hopefully leave with basic ChucK programming skills, awareness of possible uses, as well as examples and documentation provided in the workshop. ChucK is freely available, cross-platform, and open-source. http://chuck.cs.princeton.edu/ --- WORKSHOP SCHEDULE: Presentation: What is ChucK? * uses of ChucK (real-time synthesis/analysis, composition/performance, experimentation/education, laptop orchestras) * "strongly-timed": precise control over time * what is concurrent programming and using it for music * on-the-fly programming (write/edit code at runtime) workshop: part 1 (language basics) * syntax and semantics - overview - types, values, variables - operators - control structures * real-time sound synthesis * unit generators * manipulating time to make timbres and music * functions, arrays (modularizing and organizing) * concurrency, processes, shreds, events (powerful music programming) * basic on-the-fly programming with ChucK workshop: part 2 (extended examples) * extended examples - mapping controllers via MIDI and OpenSoundControl (OSC) - creating instruments using laptop capabilities (keyboard, trackpad, sudden motion sensor, mic) - network synchronization - gui control with the audicle/miniAudicle --- BIO Ge Wang (http://ccrma.stanford.edu/~ge/) received his B.S. in Computer Science in 2000 from Duke University, PhD (soon) in Computer Science (advisor Perry Cook) in 2007 from Princeton University, and is currently an assistant professor at Stanford University in the Center for Computer Research in Music and Acoustics (CCRMA). His research interests include interactive software systems for computer music, programming languages, sound synthesis and analysis, music information retrieval, new performance ensembles (e.g., laptop orchestras) and paradigms (e.g., live coding), visualization, interfaces for human-computer interaction, interactive audio over networks, and methodologies for education at the intersection of computer science and music. Ge is the chief architect and creator of the ChucK audio programming language. He is a founding developer and co-director of the Princeton Laptop Orchestra (PLOrk), and a co-creator of the TAPESTREA sound design environment. Ge composes and performs via various electro-acoustic and computer-mediated means. At CCRMA, Ge continues to research and develop ideas and systems for computer music (including ChucK), works on new music, and plans to initiate a Stanford Laptop Orchestra.

I'll look into it. Eventually, I would like to have dual screen recording for presenter and presentation. It seems possible that we may be able to record a single camera version. I'll check in with Ge.

Our visual programming tools Max/MSP and Jitter serve as the creative engine behind thousands of innovative projects. More information about Cycling '74 and its entire product line available at http://www.cycling74.com Craig Latta ----------------- Craig Latta is descended from a long line of itinerant researchers. Asking only for a fast network connection and an occasional glimpse at the sky, he explores the hinterlands of experimental music and computer science. Craig earned simultaneous bachelor degrees in music and computer science from UC Berkeley in 1991. Later that year, he discovered dynamic object programming with the Smalltalk system and realized that improvisational musical informatics was his thing. He enjoyed a variety of ambitious projects at ParcPlace Systems, Atari Games, Interval Research, the IBM Watson Research Center, and the Bootstrap Institute. In 2004, he fell in with the highly suspicious "livecoding" crowd (toplap.org), and two years after that joined the multimedia improv group "dud" (dudland.com). This afternoon he worked for the Fuji Xerox Palo Alto Laboratory. At twilight he went for a nice walk. Now, under cover of night, he pursues the NetJam project (netjam.org), a music improvisation network. Pyramind - Institute For Advanced Digital Audio Training (our host) ----------------------------------------------------------------------------------------------------- Designed for the professional and developing recording artist, Pyramind's certificate programs are the result of over fifty years of collective experience in: production, composition, sound design, engineering, mixing, mastering, studio design and installation. The curriculums are firmly based on the three foundations needed for success: technology, creativity and business.

OSC multiple host bug
by Daniel Trueman 29 Dec '07

29 Dec '07

an OSC bug that took a little bit to isolate. i've put it on the bug wiki: http://wiki.cs.princeton.edu/index.php/OSC_multiple_port_bug not the end of the world, but it can raise issues when working with multiple machines and perhaps GUI apps using OSC to communicate with chuck. dt

chuckctrl python application (was: Controling Chuck - building accessible GUI)
by Stephen Sinclair 29 Dec '07

29 Dec '07

> OOPS! That wasn't supposed to goto the list. > -- Rich Heheh... but since it did... On the subject of user interfaces, I've been working on a little something for controlling chuck for my own needs. I've written a little Python program (using GTK and Cairo for drawing) which interfaces between my MIDI controller and chuck. Each knob in the interface can automatically be assigned to an OSC control, which is announced by the chuck script. The user can, at runtime, load various chuck scripts for each column of knobs on my MIDI controller and those knobs get automagically assigned to specific OSC messages for the script. (Each script, in my case, is playing some kind of loopy thing, but that's not entirely necessary.) The MIDI/OSC part is written in C++, using RtMidi and LibLo. It works quite well, so far. Still needs some work, and I've had to put it on the backburner for the moment, but I thought I may as well post the code anyway. Just thought it was worth mentioning another approach. Using python, I managed to slap together a fairly functional application in about a week and a half, which was pretty cool. Grab it with git: git-clone http://www.music.mcgill.ca/~sinclair/git/chuckctrl.git (Sorry I'll post a tarballs sometime, just not right now since it's 1:45am.) cheers, Steve

Controling Chuck - building accessible GUI
by Rich Caloggero 28 Dec '07

28 Dec '07

There was a thread on this list back in January about control of chuck via OSC, a Python package. I have a few questions: First, I'm blind and use a screen reader. I want to build something that allows me to control chuck sreds via a GUI. I don't like Python much for programming, and am not sure if OSC would even work with my screen reader (anyone have any quick demos I could try just to see if the screen reader will deal with the UI toolkit at all)? What I was thinking of doing is building something in Mozilla's XUL language. This does have the ability to send network packets, and also can execute shell commands. So, was thinking about writing code in chuck and then pass arguments to each .ck file to change parameters. Of course, this might not work so smoothly if we wanted to change things on the fly. FOr this I guess I'd need to implement something like OSC's message passing scheme in XUL. Any advice, or suggestions? Anyone interested in rewriting audical so it works with a screen reader? There are so many great software synthesizers on the market now that work as both stand alone and/or plugins to popular hosts like Cakewalk's Sonar, but none that I've ever tried will allow the screen reader enough control to do real sound design. With effort, one can usually figure out how to change presets, but in a large number of cases even this is not possible. I was hoping that chuck could be used to build a fully accessible sound designers toolbox that could allow one to do things quickly and easily without having to write too much code. I've obviously never used it because it is very graphically oriented, but think of something like PD "Pure Data". You aparently can build all sorts of neat stuff by just plugging stuff together, without having to write a line of code. Thanx for any thoughts/suggestions... -- Rich

Compiling chuck on UbuntuStudioGutsy32
by Eric Hedekar 28 Dec '07

28 Dec '07

Hi, I've just downgraded from UbuntuStudioGutsy64 and I'm attempting to get Chuck running but I can't seem to understand this error that I'm getting. I have downloaded rtaudio4.0.3 and it looks like it compiled fine. make linux-jack make -f makefile.jack make[1]: Entering directory `/home/stochastic/Desktop/ChucK/chuck- 1.2.1.1/src' g++ -D__LINUX_JACK__ -c -O3 -D__CK_SNDFILE_NATIVE__ rtaudio.cpp rtaudio.cpp:2715:23: error: jack/jack.h: No such file or directory rtaudio.cpp:2721: error: ISO C++ forbids declaration of 'jack_client_t' with no type rtaudio.cpp:2721: error: expected ';' before '*' token rtaudio.cpp:2722: error: ISO C++ forbids declaration of 'jack_port_t' with no type rtaudio.cpp....... what obvious part am I missing? It would really be nice if some proper Linux documentation could be written into the upcoming versions of the install tutorial. I'd be happy to help write it once I understand it. Thanks. -Eric
