MAUI Window Shooting Game
by Les Hall 17 Jul '09

17 Jul '09

Here is a fun little game that involves some MAUI abuse - moving target windows! Click on the moving target button to get a smaller, faster target window and an exciting phasor sound (from Kassen). Every mouse click makes the window faster, hit or miss. It's classic 1980's arcade excitement; I found that the growing tension of the speed and noise was rather exhilarating. Krank up the volume and blast away! I hope it's OK to post code to the list (it's only 4.5 kB) - I seem to recall posting code works, we'll see... Enjoy, Les

Kassen's Phasor
by Les Hall 17 Jul '09

I just gotta share this one-liner that Kassen posted. It rocks! SubNoise s=>dac;int n;while(++n%241+1=>s.rate){(n%83)*ms+ms=>now;5=>Std.srand;} Try ckicking on "replace shred" in miniAudicle a few times, it's a phasor! Les

CNoise
by Kassen 14 Jul '09

14 Jul '09

Fellow ChucKists. CNoise is under-documented, the only official reference to it seems to be that "cnoise" is depreciated, with "CNoise" being prefered since 1.2.0.7. Still it's there in the source and can be used without errors. However, it doesn't seem to work like I expect it to. Based on the source I'd say correct usage should be something like this; CNoise n => dac; "white" => n.mode; second => now; "pink" => n.mode; second => now; "flip" => n.mode; second => now; "xor" => n.mode; second => now; "brown" => n.mode; second => now; "fbm" => n.mode; second => now; This does indeed compile but all I get is one type of noise only. Could somebody kindly help or explain? Yours, Kas.

Std.srand() abuse
by Kassen 14 Jul '09

14 Jul '09

Dear list, While exploring noise UGens I chanced upon the rather interesting technique of periodically resetting Std.srand() which sets the seed for noise in ChucK, thus resetting the output of the noise UGens; //mind your speakers, ears and neighbours! SubNoise n => dac; .2 => n.gain; while(1) { ((now/2::second)$int)%8 + 2 => n.rate; now%250::ms+ms=>now; 5 => Std.srand; } Interestingly this type of modulation is system-wide so running two files that both try to do this at the same time will result in rather complex sounds. Have fun, Kas.

The ChucK Show
by Les Hall 11 Jul '09

11 Jul '09

Hi folks, The ChucK Show this week was our best one ever. Sunshine is back in town and she always makes the show fun. I wrote a 1,000 line controller program with lots of bells and whistles. There were contributions from two newbie ChucKists, mattb was the ChucKist of the week, we took a quick tour of the Princeton ChucK website and went through a bunch of examples. Plus I played guitar a little bit as I have newly learned a basic finger picking technique. For next week I'd like to continue the exploration of the examples, but I'm not overly familiar with the entire collection of what's there. Would anyone on the list mind suggesting some examples that make good audio for the show? I will go through the STK directory, but I am unfamiliar with all of the other directories and it would be torture to go through *everything* this week before the show. So suggestions are welcome, thanks. Enjoy! Les (Inventor)

chuck mode for emacs
by Kao Cardoso Felix 05 Jul '09

05 Jul '09

Hello folks, I've just discovered and started learning ChucK and It's very neat. As I'm an Emacs user I downloaded the emacs mode for editing ChucK files. It was rather old and was missing some functionality so I've made an update. http://bitbucket.org/kcfelix/emacsd/src/tip/my-lisp/chuck-mode.el I've changed the syntax highlight to be more consistent with how other languages are highlighted inside Emacs and added all keywords, types and library functions listed on the documentation. Class and method name highlighting is not working yet, but I plan on adding it soon. Code to run the ChucK VM as an inferior process inside Emacs was commented because it wasn't working before. I've made it work and changed some keybings. Now it work like this: C-c C-c inside a ChucK buffer will send the buffer code to the VM. If there's no VM process one will be created. C-c C-d remove a shred from the VM by a numeric id (is there other ways to identify shreds besides numbers?) C-c C-r replace a shred with the code on the current buffer. I also added support for easy customization for the path of the chuck executable, so you don't have to edit lisp code to change it. Well, I'm planning to update it frequently to make it better according to my use of it, but if there's anyone using Emacs for ChucK and want to give some advice it would be very nice :) []'s -- Kao Cardoso Félix Página pessoal: http://www.inf.ufrgs.br/~kcfelix Blog: http://kaofelix.blogspot.com

Music Hack Day, London 11-12th July.
by ynohtna 03 Jul '09

Any ChucKists attending Music Hack Day next weekend? http://musichackday.org/ If you are, and fancy collaborating on a project that involves using ChucK to generate something hopefully (!) cool, then please get in touch. :) Cheers, Anthony.
