Chuck on windows7 64-bit - OTF and OSC not working
by Rich Caloggero 12 Sep '14

12 Sep '14

I'm using latest chuck 1.3.4.0 on windows7 64-bit. I can’t seem to get chuck to deal with the network at all. * -- probe crashes chuck; * any otf command like + crashes chuck; * chuck –loop seems to work, but subsequent otf commands like + cause a crash, even when specifying host and port explicitly The looped process crashes with the windows error (unexpected error – program needs to close)... The chuck + command reports “remote operation timed out”. I’ve tried with various combinations of --remote and --port in the "chuck +" command and combinations of --port and --loop and --server in the initial process. I also happen to be blind, so the miniaudical doesn't work for me at all! THe --probe command crashes chuck so its difficult to get an error report, but windows just says that a critical error has occured and the program needs to close; no other info is given. I've not been able to find any info on similar crashes online.

GUI builders?
by Peter Lutek 11 Sep '14

11 Sep '14

greetings... it's good to be back in touch with the ChucK community! i'm re-examining ChucK after a number of years since i experimented a little bit with it, as a possible alternative platform for a live performance instrument which has been implemented in pd until now. so far, i have one question which i don't see addressed directly in the various docs: is there some facility, native to ChucK, for building any GUI elements for use during performance?... things like sliders, knobs, and toggles, for both input (from keyboard or mouse) and to display values incoming from various MIDI controllers. i guess a front-end could be built in pd, but that just seems silly. somehow, i'm beginning to suspect that such a visual front-end might be a little outside the "ChucK paradigm"?! please let me know if you guys have some good approaches to this kind of thing! thanks... cheers! .pltk. -- Peter Lutek improvising musician in Toronto, Canada http://peterlutek.com

Console font size
by Daniel Chapiro 04 Sep '14

04 Sep '14

Hi - is there a way to change the font size that ChucK uses for the console window? (I'm using size 14 for the ChucK source windows, but I can barely read the ~11 fonts of the console…). Thanks! --Daniel

limit on number of OSC addresses you can listen to?
by Ben Steinberg 25 Aug '14

25 Aug '14

I've posted about this to the electro-music forum: http://electro-music.com/forum/viewtopic.php?p=402793 In trying to write some code for the Illucia dtr, I found that adding addresses to an OscIn object appeared not to work after twelve addresses. I wrote a test program that wasn't illucia-specific; the following code starts 16 OSC transmitters and 16 receivers. When you run it, you can see that transmitters 0-15 all transmit, but only receivers 0-11 receive. for ( 0 => int i ; i < 16 ; i++ ) { spork ~ output(i); spork ~ input(i); } while ( true ) { 1::second => now; } fun void output(int number) { 12008 => int port; "localhost" => string hostname; OscOut xmit; xmit.dest(hostname, port); while (true) { Math.random2f(5.5, 8.5) => float wait; wait::second => now; xmit.start("/tester/what/" + number); Math.random2f(0.0, 1.0) => float temp => xmit.add; xmit.send(); <<< "sent", number, temp >>>; } } fun void input(int number) { OscIn oin; OscMsg msg; 12008 => oin.port; oin.addAddress("/tester/what/" + number + ", f"); float val; while (true) { oin => now; while ( oin.recv(msg) != 0 ) { msg.getFloat(0) => val; <<< "received", number, val >>>; } 5::ms => now; } } I'm running ChucK 1.3.4 on Mavericks, with and without miniAudicle.

ChucK code to connect MIDI controller to some UGen STK
by Daniel Chapiro 18 Aug '14

18 Aug '14

Hi - I'm new to ChuK and I have a few questions: (1) I would like to experiment with coding different sound textures in ChucK, but then play with a WX-5, rather than ChucK code. To not re-invent the wheel, I'm looking first for ChucK code that would capture the messages sent by a MIDI wind controller (using ChucK's MIDI events), and drive a ChucK STK UGen (such as a clarinet, or other). (2) I have not found this in http://wiki.cs.princeton.edu/index.php/ChucK/Programs, and I was wondering if there are any other source repositories (unfortunately, Googling for anything + ChucK is no good, as Chuck is such a common word… ) (3) Finally, is there a way to search the full user archives (in https://lists.cs.princeton.edu/pipermail/chuck-users/) without opening every month's entry? Thanks! --Dan

Should it not be simply forbidden to redefine a variable like that in a sub-class ? When you assign instead of declare, the problem disappears. So perhaps, instead of 'fixing' the bug, we should forbid this kind of use of scope (chuck should throw an error if you try) ?

Scope bug?
by Ian South-Dickinson 07 Aug '14

07 Aug '14

I encountered a strange case where a variable was changing value within the scope of an if statement, because I had a superclass with an identical variable name. I am able to reproduce it with this simple case: class A { 10000 => int foo; } class B extends A { fun void bar() { 0 => int foo; <<< "a", foo >>>; { <<< "b", foo >>>; } <<< "c", foo >>>; } } Prints out: a 0 b 10000 c 0

Thanks for your help, Joel - and Spencer. :) I think I need some extra software for compiling ChucK - I'll look into it. I have a more recent Intel Mac laptop, but the thing about the G5 is it has the PCI slots for my MOTU 24io. I would need to get another interface to use ChucK on the laptop. I could pick up an eight channel USB MOTU fairly cheaply.

Re: [chuck-users] 147th shred removed...segmentation fault? (Ryan Supak)
by Perry R Cook 30 Jun '14

30 Jun '14

I have lots of programs that spork hundreds or thousands of shreds without this error. So, without seeing your code, my guesses (and questions) are as follows: Are you running this on a small memory architecture? Since you say headless, I'm guessing maybe Raspberry Pi? It could be that you're running out of memory, so see next question. Does the shred that you're sporking declare new UGs or require memory to be allocated (arrays, lots of string manipulation, etc.)? In general, this is a bad idea if you can avoid it. ChucK does no garbage collection, which means that you need to be cautious about declaring memory. So even a shred as simple as: fun void mySine() { SinOsc s => dac; Math.random2f(100,1000) => s.freq; second => now; s =< dac; } will eat up memory, because even though the SinOsc is unchucked and never computes again, the memory for that structure is still around. We want, someday to make ChucK a proper garbage collecting language, but it's hard, especially for real-time systems. If this turns out to be your issue, then one way to handle this is to make a global pool of fixed resources and have your shred grab from that. Like classic "round robin voice stealing" in synthesizers: SinOsc s[100]; 0 => int next2Use; fun void mySine() { next2Use => int thisOne; 1 +=> next2Use; if (next2Use > 99) 0 => next2Use; s[thisOne] => dac; Math.random2f(100,1000) => s[thisOne].freq; second => now; s[thisOne] =< dac; } // to test: while (1) { Math.random2f(0.01,0.1) :: second => now; spork ~ mySine(); } I just fired up a few dozen of these running in parallel, VM showed 2600 total shreds running, no problem (and no clicks or dropouts!!). Hope this helps, if none of this applies, then you may have discovered a strange bug. Source code please, and we can all scratch our heads on it. Thanx!!

Latency issues on Windows
by Conor Barry 24 Jun '14

24 Jun '14

Hello! I'm putting together a workshop for visually impaired musicians to make DIY music controllers using arduino + chuck. Everything is working a charm but the only issue is latency on the Windows platform. I understand that the default windows audio drivers may be the root cause but I am wondering whether there are any alternatives or advice as to how to improve. I tried running the ASIO versions mentioned on this forum post: http://electro-music.com/forum/topic-18931-25.html However these were made with the older version of ChucK that does not feature the Serial functions introduced in the latest version which are necessary for the arduino communication. Any advice will be much appreciated! Conor B

147th shred removed...segmentation fault?
by Ryan Supak 23 Jun '14

23 Jun '14

Hi, I've got a .ck file (designed to run in headless mode) that programmatically generates and destroys shreds (for a few different purposes). The calls always look something like this: lfoModShredReference.id() => Machine.remove; spork~LFOMod(msTapTempoRate) @=> lfoModShredReference; This works flawlessly until I get to shred 147, then on exactly the 147th shred, ChucK crashes with "segmentation fault" every time. Is this a bug, or is there perhaps some startup parameter I can change to fix this? Thanks, rs

Problem: chuck --silent --srateXXXXX not timing correctly
by Ryan Supak 14 Jun '14

14 Jun '14

Hi, I'm running the latest version of chuck on OSX 10.6.9. I've got a program that doesn't process audio, but it does take MIDI input in realtime and it outputs various kinds of synchronization signals based on it. I originally tried running it with just the --silent flag but chuck was 'saying' that time durations were way shorter than they were. I attempted the same thing without the --silent flag (defaulting to onboard soundcard) and time durations were accurate. Then, I tried using both the --silent and --srate44100 flags to see if that would help, but it behaved just as it did with the --silent flag. The ultimate goal is to install this program on a Raspberry Pi without using sound at all (and chuck on RPi freaks out unless you install a bunch of other stuff, if you try to run it without the --silent flag). Anyway, is there a method or trick to make the combined usage of --silent and --srateXXXXX properly measure duration in realtime use? Thanks for any help! rs

WvOut format
by George Locke 14 Jun '14

14 Jun '14

Hi, The output format of WvOut is coming out wrong. Audacity doesn't recognize it as a wav (does not recognize type, suggests import raw), and windows media player rejects it as well. Importing the file into Audacity as raw data works somewhat, but as I'm diagnosing a dc-offset, I need an exact result. here's some example code: SinOsc s => Gain g => dac; s.freq(400); g.gain(0.5); g => WvOut w => blackhole; "blerg.wav" => string file; w.wavFilename(file); 1::second => now; w.closeFile(file); // what is the function of the argument here? can WvOut record multiple buffers at once? I'm not so experienced with chuck but experienced in "normal" computer programming. Running miniAudicle 1.3.1 with chuck 1.3.3.0 on windows 7 pro sp1 (32 bit). Thanks, George
