Problems with running VM in terminal (Windows 7 64-bit)
by [chriswicks] 25 Apr '12

25 Apr '12

Hello all! I am having a strange problem on my desktop PC running Windows 7 Professional 64-bit. I have the chuck.exe binary installed for both the Windows cmd prompt (Windows/System32 folder) and for Cygwin, and it works directly (i.e. chuck foo.ck). However, when I start the VM using chuck --loop, I can't seem to add any shreds to the VM. It doesn't throw an error message or anything, and it appears to start as it should, it just doesn't seem to be listening to any input that I throw at it. I type "chuck + foo.ck" and there is no error message and no output in the terminal that is running "chuck --loop". The same error occurs in both Cygwin and in the basic Windows command-line programs. I have everything working fine (having followed the same exact steps) on my laptop running Windows 7 Home Premium 64-bit, and everything works fine (with some Jack finagling) on my Linux partition on both machines, but I'd like to be able to work in Windows on my desktop, as that is where I spend the bulk of my time for now. Thanks for any advice!

ChucK on the web: NodeJS / HTML5
by Matt Diamond 20 Apr '12

Has anyone had any experience with using ChucK in a web context? For example, two things I'd be interested in as a web developer: 1) streaming ChucK audio output from a NodeJS server to the browser 2) a javascript client-side ChucK implementation utilizing the Web Audio API Has there been any work on either of these?

esp.beat - cybernetic orchestra CD
by David Ogborn 19 Apr '12

19 Apr '12

Hello friends, The debut album "esp.beat" from the Cybernetic Orchestra here at McMaster was released in a special CD release event ("Resonant") at the Factory Media Arts Centre during Hamilton's monthly James Street N art crawl last Friday (April 13 2012). We distributed just over 200 CDs to an enthusiastic audience of just over 300 people - it was quite a blast! I'm sure we'll do it again soon... The entire album is available online via soundcloud - here's the link: http://soundcloud.com/cyberneticorchestra/sets/esp-beat The album has been made available under a Creative Commons Attribution Non-commercial Share-a-like license (CC BY-NC-SA). How is the orchestra performing this music you may ask? A lot of it is live coding using Chuck and the miniAudicle. Some of it is some MaxMSP instruments created by orchestra members. Behind the scenes we are using rough prototypes of the espTools software (forthcoming) for communication and beat sharing. We'll be posting some more improv recordings (including some from the CD release party) shortly, and some video footage collected over the past 14 months throughout April and May. But in the meantime we hope you enjoy this acousmatic edition of our music! Yours truly, David, on behalf of the Cybernetic Orchestra ------------------------------------------------------------------- Dr. David Ogborn, Assistant Professor Communication Studies & Multimedia Director, Cybernetic Orchestra & ESP Studio McMaster University, Hamilton, Canada ogbornd --at-- mcmaster.ca http://davidogborn.net http://twitter.com/ogbornd http://esp.mcmaster.ca (Cybernetic Orchestra) 1-905-525-9140 ext 27603

Gedit Plugin for ChucK?
by [chriswicks] 18 Apr '12

18 Apr '12

Does anyone know of a plugin for gedit that contains syntax/keyword highlighting/etc. for editing ChucK programs? I really want to like the miniAudicle, and it has a lot of potential, but I have issues saving files if I instantiate the program via the terminal. Issues meaning that it won't save any changes that I make to a file if I instantiate miniAudicle from the terminal, at least on the Linux version (Ubuntu 32-bit, miniAudicle built from most recent source). Thanks for any info!

different classes and files talking to each other
by henrique matias 18 Apr '12

18 Apr '12

Hello folks, hope everything is great over there! ( : Am new to chuck, needless to say am impressed! Am a bit confused how to share and control different classes and files from a central "machine". The first idea was to create a static Event var and put every class listening to this event, but unfortunately we still can't instantiate non-native objects as static. Would someone please point me to some basic structure/example? Thanks a lot! Happy chucking!

Beginner question about audio artifacts
by Chris Wicks 15 Apr '12

15 Apr '12

Hello! I'm relatively new to programming and to ChucK in particular. I have an issue in which, whenever a new shred is introduced to the virtual machine (chuck --loop running in a terminal....also happens on miniAudicle) I get significant artifacts. I've tried using the command line option for increasing buffer size to no avail. I'm running ChucK on Windows 7 Pro 64-bit. Audio drivers are Realtek (may not be the latest version). I get the same issue on mu laptop running Windows 7 Home Premium 64-bit. Do I need to bite the bullet and shell out for a dedicated sound card? Could it potentially be a driver issue? I'm at a bit of a loss. Thanks for any help!

I don't know if it works on Lion - it's a bit old - but it functions great on Snow Leopard. Anthony.
