sample rate defaults (jack)
by Tristan Matthews 22 Jul '08

22 Jul '08

Hi, I'm using ChucK with jack (compiled with makefile.jack). I was wondering if there's a way to set the default sample rate for chuck to be 44100, rather than 48000. I could change this guy: digiio_rtaudio.h:58:#define SAMPLING_RATE_DEFAULT 48000 // sampling rate but I thought I'd see if there were other options. Even better would be having an option to get the sample rate from the jack server. Best, Tristan -- Tristan Matthews Société des arts technologiques [SAT] email: tristan(a)sat.qc.ca web: http://www.music.mcgill.ca/~tmatthews

chuck 1.2.1.2 still doesn't work on 64-bit linux
by Michael Heuer 21 Jul '08

21 Jul '08

All, Has anyone been able to get version 1.2.1.2 to work on 64-bit linux, without 32-bit compat libraries? It builds fine for me but seg faults on nearly every example. michael

ChucK Lab Video
by Inventor-66＠comcast.net 19 Jul '08

19 Jul '08

Hi Spencer et. al., Here is a video under 15 minutes of me making music with ChucK Lab, which is basically an explosion of MAUI filling the screen and making cool music. The link is here: http://www.freedomodds.com/music/ Just look at the first section underneath the introductory paragraph for the link. Warning it is over 70 MB. Plus I got the levels wrong and you can barely make out my voice. But aside from that it's cool. Les p.s. I might make more ChucK videos.

USB Accelerometer Product Coming
by Inventor-66＠comcast.net 19 Jul '08

19 Jul '08

Hi, For all us HID-heads, I thought I would mention the new product that I'm helping to develop. I was gonna make a 3-axis accelerometer on a USB interface. When I approached the company that makes the USB interface, I suggested they might want to make such a product for their product line. They replied with excitement, and a new product was born! I am not sure of its exact form down the road but they have the technology to make this product any way we want it to be. I figure a single 3-axis accelerometer plus their standard 8-I/O gamepad / joystick interface on a board the size of a stick of gum. Wrigley's will be proud. So please be aware that coming down the river is a new, hopefully inexpensive, HID part for us all to enjoy. Cheers! Les

getting ADSR::XTime()
by eduard 17 Jul '08

17 Jul '08

Hi list, I'm afraid there is a bug on the getters side of the ADSR UGen. One can set adsr::attackTime( 10::ms ) and gets adsr::attackTime() as 0.010::samp, instead of (0.010*SR)::samp. So, to be able to use adsr::attackTime() => now correctly, one should do: adsr::attackTime()*sr => now Which I don't think is the way one would expect. Could anyone confirm the same behaviour, so I can add it to the wiki-bug-list? eduard SinOsc s => ADSR env => Gain g => dac; env.attackTime( 10::ms ); env.decayTime( 5::ms ); env.releaseTime( 1000::ms ); <<<"env_region", "\tstate()", "\tcur time[ms]", "\ttime[samp]", "\ttime[ms]">>>; <<<"-------------------------------------------------------------------- -------","\n">>>; while( true ) { env.keyOn(); <<< "start of att", "\t", env.state(), "\t", now/ms , "\t", env.attackTime()/samp, "\t", env.attackTime()/ms>>>; env.attackTime() => now; <<< "end of att", "\t", env.state(), "\t", now/ms >>>; <<< "start of dcy", "\t", env.state(), "\t", now/ms, "\t", env.decayTime()/samp, "\t", env.decayTime()/ms >>>; env.decayTime() => now; <<< "end of dcy", "\t", env.state(), "\t", now/ms >>>; env.keyOff(); <<< "start release", "\t", env.state(), "\t", now/ms, "\t", env.releaseTime()/samp, "\t", env.releaseTime()/ms >>>; env.releaseTime() => now; <<<"end release", "\t", env.state(), "\t", now/ms >>>; 1::second => now; <<< "\n","******************\n">>>;

Intercepting and Routing Audio
by Inventor-66＠comcast.net 16 Jul '08

16 Jul '08

Hi again, I would like to intercept the output of iTunes on my eMac and send it into ChucK so I can use the Ambiophonic Processor that Howard Moscovitz of the forum wrote, then send that to the dac. Can I do this with a freeware package of some sort, and is it something to add to the feature request list of ChucK? It sure seems like the sort of thing that one should be able to do. Les

Quick Joystick Question
by Inventor-66＠comcast.net 14 Jul '08

14 Jul '08

Hi, I just have a quick question for planning my HID project. Does the ChucK joystick HID interface support all six joystick axes? I saw that one of the examples on the web page uses four axes, so I believe the answer to be "yes", but I need to be certain. Thanks, Les Hall

Bouncing Baby Website
by Inventor-66＠comcast.net 13 Jul '08

13 Jul '08

Hi yet again, I would like to announce the birth of a bouncing baby website, my Guitar Motion Sensor project site. You may recall me writing at least one long, excited email about my plans to do a guitar HID project. Well, I'm getting really close to buying the parts and out of frustration waiting for finances to line up plus a desire to share the knowledge, I created a three-page website with all of my plans and reasoning about the project. The url is here: http://www.freedomodds.com/music/gms.html Actually after consulting forum contributors, especially Kassen, I have the hardware boiled down to two circuit boards that will cost $35 each, and a mere five solder connections. Then I'll mount the gizmo on my guitar's headstock and run a long USB cable down the length of the guitar and to the computer. I tried to be humorous and light-hearted in my writing style so people would enjoy reading it. I'd appreciate any comments about the site especially regarding project construction details or possible gotchas / errors. Plus I'll note that my website traffic has more than doubled in the few days since I put the site up, so I believe that people are interested in guitar effects HID. Making the world a better place via ChucK - kinda feels good, eh? Cheers! Les

Thanks folks, Jack wouldn't run on my machine, it quit unexpectedly when I tried to run it. Perhaps I need an older version of the software for my 10.3.9 OSX, but anyway SoundFlower is working great! WooHoo, now I can even do effects processing of audio from iTunes! Les

STK Modulate -- does it work?
by Chris McDaniel 08 Jul '08

08 Jul '08

Hello, Wondering if someone can explain STK Modulate to me; I just don't seem to get it! The code below is just a little test to try and figure it out -- works as expected if you comment out all the Modulate related bits, but as is, makes a muddy hum... Obviously I'm doing something wrong! Can anyone shine some light on this for me? Thanks ----------------------------------- // SinOsc m => dac; // the offending portion! SinOsc m => Modulate modu => dac; 60 => modu.vibratoRate; 1 => modu.vibratoGain; 1 => modu.randomGain; // fine from here... 200 => float freq; 0.3 => m.gain; while (true) { // just to keep it interesting... Std.rand2(1, 4) => int multipler; ((freq * 2) - freq) / 12 => float step; step * multipler => float newfreq; if (freq > 2000.0 || freq < 150.0) { if (freq < 150.0) { freq + newfreq => freq; } else { freq - newfreq => freq; } } else { if ( maybe ) { freq + newfreq => freq; } else { freq - newfreq => freq; } } freq => m.freq; 250::ms => now; }
