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; }

Chorus.modDepth broken?
by Atte André Jensen 08 Jul '08

08 Jul '08

Hi It seems to me that the modDepth of chorus doesn't work, depth is always very deep, it has some effect on the sound, but very subtle and not at all what I expected. Can anyone confirm this? 5::second => dur play; 2::second => dur pause; SinOsc s => Chorus c => dac; .5 => float gain; <<<"first the default settings - sounds strange">>>; inBetween(); <<<"setting the modDepth to 0">>>; 0 => c.modDepth; inBetween(); <<<"setting the modDepth to 1">>>; 1 => c.modDepth; inBetween(); <<<"setting the modDepth to 1000">>>; 1000 => c.modDepth; inBetween(); <<<"setting the modDepth to .001">>>; .001 => c.modDepth; inBetween(); <<<"something like this is the best that can be achieved IFAICT">>>; .3 => c.mix; .001 => c.modFreq; play => now; fun void inBetween(){ gain => s.gain; play => now; 0 => s.gain; pause => now; gain => s.gain; } -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk

webcam and touch
by lucas samaruga 06 Jul '08

Hi all Thinking of support for webcams, would it not be a good idea to integrate touchlib within chuck utilities? http://www.nuigroup.com/touchlib/ I do not know if this library is adequate, but the things I've seen do with it are very good. I think it would be a good utility for HID! What do you think? (perhaps an observation misplaced) Greetings Lucas

ChucK mirror site up!
by Ge Wang 05 Jul '08

05 Jul '08

Dear all, Due to increased unavailability of the primary ChucK site, we now have coast to coast mirrors! The main ChucK site at Princeton: http://chuck.cs.princeton.edu/ New left coast ChucK mirror at Stanford: http://chuck.stanford.edu/ These are synchronized from the same repository and should contain identical content. Hopefully at least one of these should be up at all times... Happy ChucKing! Ge!
