ChucK and STDIN
by DANIEL MAGNUSZEWSKI 12 Jul '06

12 Jul '06

All, Is there a way to have a ChucK program take input from STDIN while running? I have seen the events page ( http://chuck.cs.princeton.edu/doc/language/event.html ) where it discusses MIDI/OSC events, but I would like to pass information via the command line or through a pipe. Does this make sense? Is there a reason why this feature is not implemented, or am I just asking for something crazy?! Thoughts? Thanks. -Dan

class confusion
by Atte André Jensen 11 Jul '06

Hi Attached is a piece of useless code that confuses me. Should it matter where class kidA is defined? Is this a bug? -- peace, love & harmony Atte http://www.atte.dk | quartet: http://www.anagrammer.dk http://www.atte.dk/gps | compositions: http://www.atte.dk/compositions class A{ fun void greet(){ <<<"hello">>>; } } // works when defined here //class kidA extends A {} class B{ fun void greet(){ } } class kidB extends B{ 3 => int nb_kids; kidA kids[nb_kids]; fun void greet(){ for(0 => int i; i<kids.cap(); i++){ kids[i].greet(); } } } // doesn't work when defined here class kidA extends A {} /* A a; a.greet(); kidA kid_a; kid_a.greet(); */ kidB kid_b; kid_b.greet();

machine.add issue
by Atte André Jensen 11 Jul '06

11 Jul '06

Hi I discovered a problem with machine.add. I called it like this: ["sd_random","sandpaper_16", "breakbeat_breezing", "tri_bass_random","sine_penta_16", "cabassa_offbeat", "noise_hit_period", "moog_melody", "sh", "ob_pad_5th","ob_pad_root" "bd_random"] @=> string load[]; for(0=>int i;i<load.cap();i++) machine.add(load[i]); Even if I just added a single of the simpler files, CPU usage was rising, until after about 6 minutes 100% was used and the audio broke up. I could send a couple of files showing this behavior, but since it seems very consistent, I thought it might not be necessary. Needless to say, if I simply started everything from bash (or added .ck files from emacs) everything was fine. This is both running 1.2.0.5 and 1.2.0.6-rc3 with alsa under Linux on a patched 2.6.15.6 kernel. -- peace, love & harmony Atte http://www.atte.dk | quartet: http://www.anagrammer.dk http://www.atte.dk/gps | compositions: http://www.atte.dk/compositions

MIDI port aliases
by Bruce Murphy 10 Jul '06

10 Jul '06

UNder Mac OS X, CoreMIDI provides really nifty aliases for ports which are plugged into named devices. This permits them to be easily identified by users with multiple interfaces. These mappings are set up in the audiomid tool by creating devices and setting up wiring The mappings are also useful for named virtual ports created by other MIDI aware applications. COreMIDI also provides an interface for getting the name of the MIDI device providing the port which can further aid identification. IT would be really nice if the chuck probe stuff actually provided this feature. It would be equally nice if a MIDI port open had a "name matching this string" facility, so devices could be moved around between interfaces and provided you had updated audiomidi, all the chuck software looking for that device would Just Work. Thoughts? B> -- Packrat (BSc/BE;COSO;Wombat Implementor) Nihil illegitemi carbovndvm

chuck manual errata
by eduard aylon 10 Jul '06

10 Jul '06

Hello Adam et al, I'd like to draw your attention on what I believe is an error in the Chuck manual. It seems to me that the Blit ugen section is not correct. According to the manual, Blit has only next() and value() as member functions. However, looking at ugen_stk.h reveals that Blit, as BlitSquare and BlitSaw, has freq(), harmonics() and phase() as memebers and not next () nor value(). Cheers, Eduard

block comments

Hi http://chuck.cs.princeton.edu/doc/language/overview.html#comment states that "For now, there is no block commenting". However, I find that /* and */ works as block comments. Maybe this should be updated in the doc... -- peace, love & harmony Atte http://www.atte.dk | quartet: http://www.anagrammer.dk http://www.atte.dk/gps | compositions: http://www.atte.dk/compositions

synchronizing multible chucks
by Atte André Jensen 07 Jul '06

07 Jul '06

Hi Suppose I have two machines each running it's own chuck. Is it possible (and if so, how?) to synchronize the two, for instance having them play a bleep at exactly the same time? How did you, Perry and Ge, go about handling this in the duets I downloaded from the website? -- peace, love & harmony Atte http://www.atte.dk | quartet: http://www.anagrammer.dk http://www.atte.dk/gps | compositions: http://www.atte.dk/compositions

Re: [chuck-users] Distributing ChucK (Adam Tindale)
by Ollie Glass 05 Jul '06

05 Jul '06

It's done! Breakage v14 now includes, launches, uses and closes ChucK from the Java app. Download from www.blackholeprojector.com It took some fiddling to make this work, anyone who's interested in doing the same thing might like to know I had to: 1 open the OSC ports in Java before ChucK, else JavaOSC finds they are already taken. 2 check which OS Java is running on, so "chuck" or "chuck.exe" can be called as is appropriate. 3 use a Java thread to follow ChucK's stdout and stderr streams. Leave them untended and ChucK freezes after a while. 4 register a Java application exit listener to terminate the ChucK process when the app is quit, otherwise ChucK keeps running. I'm happy to make the Java / ChucK code avaliable to anyone who'd like it. Thanks again everyone!

Answering to my previous post, and just remembered there was a HID object... I guess I could use that... thanks, Eduard
