generative program, audio problems when sporking
by Matthew Shanley 27 Apr '05

27 Apr '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've written a first version of a generative program. It's structure is based on a mixed metaphor of cell differentiation and plant growth. Much of this could obviously be better written once the next version comes out, but what I have works fine for the most part. You can find it at: http://wiki.cs.princeton.edu/index.php/IvyTree Obviously I could use a little help editing this page, but I have a more important problem. When running this on OS X, every time a new process is spoked, the audio cuts out for an instance. This has happened with versions 1.1.5.5 and 1.1.5.6. I'm afraid I haven't been able to test this on any other machines. Is this likely a problem with my machine's configuration? If so, how can I try to fix it? Is there something better I can be doing in my code to avoid this? Thanks for any advice or leads you can give me. matt - -- Matthew Shanley little secrets records and stuff http://littlesecretsrecords.com/ E-mail: matthewshanley(a)littlesecretsrecords.com GnuPG Public Key ID: 0x4DA4915C -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (Darwin) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFCb+QIIrtD7k2kkVwRArdZAJ4plYg6RbRQ1owCvAXk0lR7OWGT7gCfSw+/ a1Amy16zD7R4mMeEmoKUM3Y= =Gfn6 -----END PGP SIGNATURE-----

returning values when sporking
by Matthew Shanley 22 Apr '05

22 Apr '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I'm new to the practice of forking, and experimenting with it (well sporking) in chuck. I'm making a call along the lines of: spork ~ sporkFun(arguments) => int value; to a function: fun int sporkFun(arguments) {returs something in here} As I'm sure most of you know quite well, value doesn't get the return value from the function called by the spork, but rather the shred ID. That makes sense just fine and I can see lots of value in that. What I'm wondering is if there's a way for the child shred to return values to the parent, or as a wider question, for them to communicate in any way. I've figured out that global variables can be accessed both by parent and child, so I guess using those as flags is one way to go. Any other ideas? I think this should all be clear, but I can post code if that would help. eagerly awaiting arrays, but not envying the work by ge and the rest to bring them to us, matt - -- Matthew Shanley little secrets records and stuff http://littlesecretsrecords.com/ E-mail: matthewshanley(a)littlesecretsrecords.com GnuPG Public Key ID: 0x4DA4915C -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (Darwin) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFCaFoCIrtD7k2kkVwRAiW8AJ4n132UMPJeBpbdWRrQOCMw8aximwCdHOad NvpXub41Ucpwe58txsTWIso= =gutB -----END PGP SIGNATURE-----

using emacs mode
by Matthew Shanley 15 Apr '05

15 Apr '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I'd love to use the emacs mode by Mikael Johansson, but I've never quite figured out the emacs settings. I think it requires in .emacs the line (setq auto-mode-alist (append '(("\.ck$" . chuck-mode)) auto-mode-alist)), but i think maybe at least one other line as well. Is this very familiar to others? Also being new to os x and emacs as a .app, I'm not sure where to place the chuck.el file. If anyone can help with these things it would be much appreciated. matt - -- Matthew Shanley little secrets records and stuff http://littlesecretsrecords.com/ E-mail: matthewshanley(a)littlesecretsrecords.com GnuPG Public Key ID: 0x4DA4915C -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (Darwin) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFCXzPQIrtD7k2kkVwRAmD/AJ91eba3qmcZuh0WjNr7tcR/fYqFwgCfRSZ/ WHeXHYahemRafTjNstt3w7I= =iTEg -----END PGP SIGNATURE-----

Long Now Chimes.app
by Joe McMahon 14 Apr '05

14 Apr '05

I've mentioned over on the ChucK wiki that I was working on an OS X application that used ChucK to ring peals of the Long Now Chimes. I've got a simple first-cut version up at http://ibiblio.org/emusic-l/LNC.dmg.gz for anyone who's interested. The project was done in AppleScript Studio, letting me have Cocoa user-interface widget without having to write the support code in C, and the audio is all synthesized in ChucK, to avoid having to learn the AudioUnit stuff. The interface is currently a little rought, but it makes pretty noises, and I like it. Hope you guys enjoy it, and thanks for Chuck! (Of course, the program gets much more sophisticated when we've got arrays; I could probably port all of the peal generation code direct to ChucK at that point. Note that I am *not* rushing anybody - it works great now.) Long term, I'm planning on making it more customizable by being able to write ChucK-based plugins to make different sounds, etc., and to have a nice way of entering dates other than typing them in. --- Joe M.

april chuck's day
by Ge Wang 01 Apr '05

01 Apr '05

Dear All, Today is April 1st (since it's noon here, that should still be true for just about everyone), so technically, we are already late on our release 'date' of March. Our apologies. We are still in the testing/bug fixing/packaging stage of chuck-1.2.0.0, and hope to release something reasonable by this weekend. A quick status report - arrays are implemented and tested, objects are mostly implemented/tested. The only minimally essential 'showstopper' component we must complete is the bare-bone object importer. We are working around the clock to make this release as soon as possible. Stay tuned. Thanks! Best, Ge!

New guy, and questions
by paul.maddox.mail-list＠synth.net 23 Mar '05

23 Mar '05

All, Firstly I have to say wow, this looks great, loads of really neat features, well done! I've had a quick play and its pretty easy to pick up, but I have a question. One thign I want to do is to play with 'VOSIM', basically you have a train of pulses (bell curves) that make up a cycle of audio. You vary the number of, amplitude and width of each curve to change the 'tone'. Now I can see I can use a sine oscillator, square it and this will give me the bell curve, only problem here is that I get two 'bell curves' for the price of one cycle, which brings me neatly onto my next problem.. What I need to do is to change the amplitude and/or pitch of each 'pulse' at the zero crossing, great I can use Zerox, but, how do I then change the value? I had though of feeding the output of Zerox into a 'sequencer' which controls the pitch and amplitude of the sine oscillator, but I can't see a 'sequencer' type of module.. So, There are two questions firstly, Is there a sequencer module planned? and secondly, if not, how can I get round this? can I use the output of Zerox to increase a counter and use an 'if' statement to change the values of the sine oscillator? will the use of multiple 'if' statements be quick enough? Sorry for the long winded question. Paul Maddox

Fractal Melody
by Kristjan Varnik 20 Mar '05

20 Mar '05

Hello, I was thinking about Fractal Melodies as a quick way to generate complex complicated audio structures. I uploaded an example to Wiki program page. Chuck can be delighfully quick and fun to work with. Its a great design!!!!! I am working on some new compositions now, and plan to assemble a collobarative chuck piece. Stay tooned... Ge - Whats the scoop on the next version of chuck? I am getting ready for a live performance at the end of april, and was wondering if the new version of chuck would be around by then. How old is this version? Yeahz! Spring has arrived! Kristjan Varnik

Bus Error - Trying to run ChucK for the first time
by jimmak cataract 13 Mar '05

13 Mar '05

Hello, I am an ultra-newbie trying to run ChucK for the very first time, and am experiencing difficulties trying to run any of the demos. The source compiled well on OSX 10.3.7, and trying to run ChucK without any input yields: [chuck]: no input files ...... (try --help) which is what the install readme says should happen (?). However, when I try to run any examples, for example demo0.ck, I get a bus error. The last paragraph in the console output says: JAR: DeviceSetProperty inSelf 17915232 JAR: DeviceSetProperty 'sfmt' JAR: Sample Rate: 44100.000000 JAR: Encoding: 1819304813 JAR: FormatFlags: 43 JAR: Bytes per Packet: 4 JAR: Frames per Packet: 1 JAR: Bytes per Frame: 4 JAR: Channels per Frame: 1 JAR: Bits per Channel: 32 time=0.0000s Bus error The jack server is running, and I have the same thing using portaudio as the driver (not coreaudio), as well as built in audio, and not my sound card. Could someone give me some direction in getting this to work? Thanks alot for your time, regards, Stuart Woolford. Australia.
