new ideas, new bugs...
by Kassen 04 Sep '10

04 Sep '10

Fellow ChucKists, I was poking around in the source for "maybe" to try to figure out how hard Joe's idea would be to implement. So far it looked really quite easy to me, except that the chuck operator would have to be overloaded to deal with chucking floats to "likely" and "unlikely". This made me wonder what kind of error this would give; 1 => maybe; It turns out that doesn't give a error at all and instead seg-faults (latest miniAudicle, linux ALSA, canonical version except for the CNoise fix). So; regardless of whether or not we go with Joe's idea this area does need a look. I vote that we do take this idea as it would be very little work for something that would be that much fun. With a default of .75% for likely and 25% for unlikely it would have all of the advantages of the various proposed strategies and on top of that we'd get a easy "crossfade" for chance-based techniques that may span several shreds. Yours, Kas.

new version of chuck
by tempjayren＠gmail.com 03 Sep '10

one of the webpages has code examples for current chuck and upcoming for chuck 2. i can't seem to locate any data on when this is to be released. i like version 1 so much i'll probably love v2.

"Or"
by Timothy Leonido 03 Sep '10

03 Sep '10

Hallo, Once again, sorry for the rudimentary questions, but I can't seem to find the correct language for a very simple function: Instead of using Std.rand2f( ) for fluctuating volume or buf.rate, I'd like to simply have an either/or option. Play sample at a rate of 1.0 *or *1.5, randomly. The moses function (in pure data) was useful for this. Direction to the appropriate helpful would also be appreciated. Thanks so much, Tim

In/Out Fest 2010!
by Chris Gilroy 01 Sep '10

01 Sep '10

We are curious, just like you. Because of this, we decided to bring those that inspire, move, and challenge us together to write, make, perform, and teach. Musicians and artists huddled together to learn and share the secrets of computers. How to make them do the things we dream, how to control them to do those things, and hopefully stumble across some happy accidents along the way. So join us for a time of sharing, learning, and experimenting in creating computer programs and designing control interfaces for audio and video performances. Let us rejoice in all things open source! Check out this years line up including performances by: Protofuse (maker of the Protodeck) Rosa Menkman Peter Kirn Makingthenoise Ostracon Philip White and more! and workshops on Building Your Own Controller using M4L Textiles and Electronics Creating a Digital Synth with CMOS Lecture by Brian Crabtree of monome and more! get all the details here: http://inoutfest.org/

miniAudicle bug: initial C comments

It seems miniAUdicle 0.2.0 has a bug: files cannot have an initial C comment /* ... */. Perhaps to prevent people putting in useful comments. :-)

Question re: installing ChucK on Mac
by Edward Herbst 25 Aug '10

25 Aug '10

Hi, The installation instructions I downloaded say to reconfigure the terminal of a Mac but the Apple people I consulted advised me not to do that. They say reconfiguring the terminal is outside the warrantee and they see it as potentially destroying the computer! Is there another way to install ChucK without altering the terminal? Thanks for advice, Ed

Maybe * 0.7
by Tambet 24 Aug '10

24 Aug '10

http://wiki.cs.princeton.edu/index.php/ChucK/Features/Release - the most prioritized feat for next release is extending maybe. As I just thought of it today and my thoughts are better than there - I think that a simple overload for multiplication operator would be just enough. Like this: if (maybe * 0.2) { // Runs with probability of 20% } Or, more coherent, but less nice: if (maybe(0.2)) { // Runs with probability of 20% } Then, when doing switches, how to handle those? It would be nice to have something like: switch { case maybe * 0.3: case maybe * 0.5: case maybe * 0.6: case true: } In case it would automatically fix all maybes - so that actual probabilities would add up to 100% and, thus, first one is fixed to about 0.2 and second one to slightly less than 0.5 ..this would allow really nice play with probabilities (and, of course, optimizations internally).

IP address from incoming OSC message?
by Michael Heuer 20 Aug '10

20 Aug '10

Hello, Is it possible to determine the IP address of the client sending an incoming OSC message? There is no documentation on the API of the OscEvent class. I'm trying to find a way of dealing with multiple OSC clients that are sending the same OSC message. OscRecv incoming; OscEvent event; 1234 => incoming.port; incoming.listen(); server.event("/incoming", "f") @=> event; spork ~ waitForEvent(); fun void waitForEvent() { while (true) { event => now; while (event.nextMsg()) { event.getFloat() => float f; event.getIPAddress() => string client; if (client == ...) { } } } } michael
