wiimote=>chuck on linux
by Graham Percival 13 Nov '07

13 Nov '07

Hi all, I'm trying to get input from a wii controller into ChucK. One option is to use OSX+darwiinOSC to send OSC messages to chuck, but this requires OSX. There are a number of wii libraries for Linux; does anybody know if they can communicate directly with ChucK's hid input? So far I haven't been able to find a linux wii driver that sends OSC messages. Cheers, - Graham

Time logic
by Juan-Pablo Caceres 11 Nov '07

11 Nov '07

Hi there, I have another question concerning time logic. The following 2 examples are similar: // 1) while (true) { <<<"HELLO">>>; 1::second => now; } // 2) while (1::second => now) { <<<"HELLO">>>; } So the question is, is the second case using some syntactic sugar? Because conceptually it doesn't sound right to me. Maybe the chuck gurus out there can make more sense of it? Thanks! JPa.

recording Chuck output once sound has started
by Jascha Narveson 11 Nov '07

How do people like to record audio from ChucK once it has already started running? I was just playing with an interesting audio- processing patch and wanted to record the output, and thought maybe routing ChucK through Jack would work, but i didn't have any luck with that. cheers, jascha

mouse up/down controlling signal path
by Jascha Narveson 11 Nov '07

11 Nov '07

hello again, chuckists - I'd like to alter signal flow in response to input from HID devices. In this small example, i want mouse down to result in reverb, and mouse up to result in dry signal. The problem is that the reverb persists after the first mouse down - i tried unchucking in the mouse up "else if" statement, but that didn't work... thanks, all, j ----code---- adc => dac; NRev rev; Hid hi; HidMsg msg; if( !hi.openMouse( 0 ) ) me.exit(); <<< "mouse '" + hi.name() + "' ready...", "" >>>; while( true ) { // wait on event hi => now; // loop over messages while( hi.recv( msg ) ) { if( msg.isButtonDown() ) { <<<"down">>>; adc => rev => dac; } else if( msg.isButtonUp() ) { <<<"up">>>; adc => dac; } } }

Hello, I would like to chuck the output of a SinOsc into the pan parameter of a Pan2 ugen. Seems like that should be possible but I haven't figured out how to do it yet. Thanks, michael

stupid n00bie question: part IV
by AlgoMantra 09 Nov '07

09 Nov '07

Hm, happy diwali greetings from India chuckers! So. Lets say I'm shaping a curve, which is the frequency graph of a sound wave, using pygame, or some kind of GUI. So what I possibly have are two things: 1. a string of coordinates that forms the curve. 2. a parametric equation that represents the curve. What is the easiest way in ChucK, by which I can play/generate this sound in case 1) and 2). See? It's getting less stupid everyday :) (eh, Kassen?) regards, dj fadereu ------- -.- 1/f ))) --. ------- ... http://www.algomantra.com

multichannel audio
by David Birchfield 07 Nov '07

07 Nov '07

hi all, haven't yet found an answer in the archive, but apologies in advance for the newbie question: I have a motu traveler on mac 10.4.10 and would like to use the multichannel capability. When I run the 'n.ck' example script it returns that the device has only 2 channels, and I get a NullPointerException when I try to force the issue by writing to dac.chan(2). Is there a way to help Chuck see the additional channels on my device? thanks!

input from file
by Hannes Rieser 07 Nov '07

07 Nov '07

hi, i wrote a small program that allows file input/output from within chuck via OSC. You find it here: http://electro-music.com/forum/topic-21276.html this software can read files only as a whole. so you have to read the whole file before the while loop and store the read values in an array whose element you use inside the while loop. its meant as a workaround until the file input/output UGens arrive in chuck. i compiled it for the mswindows (tested on WinXP/WIN2000) platform but recently it was ported to linux also. Hannes -- Psssst! Schon vom neuen GMX MultiMessenger gehört? Der kann`s mit allen: http://www.gmx.net/de/go/multimessenger

adding a chuck class from an external file
by Juan-Pablo Caceres 06 Nov '07

06 Nov '07

Hello, Doing some research on how to add a class that is defined in an external file I came across an email Ge sent explaining this wasn't possible yet: https://lists.cs.princeton.edu/pipermail/chuck-users/2006-March/000440.html ===================================================================== foo.ck --- public class Foo { /* stuff */ } --- bar.ck --- machine.add( "foo.ck" ); Foo foo; // this won't pass the type checker --- running bar.ck first (the intended usage) would result in a type checker error 'unknown class Foo', since foo.ck won't be added until runtime and so 'Foo' is unknown when bar.ck is compiled. ===================================================================== I remember though him also saying that the way to add external functions (functions defined in an external file) was to create a classes that contains them. So is there any new way to add a class defined in an external class? Your help is greatly appreciated. JPa.
