not receiving osc in
by altern 07 Nov '06

07 Nov '06

hi i am testing osc implementation in Chuck but i dont get incomming messages. i manage to send from chuck to pd but not the other way around. i attach the pd patch and the chuck file in case anyone want to have a look. I am not sure what it could be the port should be ok as I tried with python and pd with the same ports and everything worked perfectly. So i guess i am missing something on the chuck side. thanks enrike #N canvas 0 0 466 316 12; #X obj 86 214 sendOSC; #X floatatom 87 270 5 0 0 0 - - -; #X msg 127 98 send /test 1; #X obj 308 223 print; #X obj 300 172 dumpOSC 9000; #X msg 31 72 connect localhost 9001; #X msg 125 157 send /test \$1; #X floatatom 125 137 5 0 0 0 - - -; #X obj 28 27 loadbang; #X connect 0 0 1 0; #X connect 2 0 0 0; #X connect 4 0 3 0; #X connect 5 0 0 0; #X connect 6 0 0 0; #X connect 7 0 6 0; #X connect 8 0 5 0; OscSend xmit; xmit.setHost( "localhost", 9000); // create our OSC receiver OscRecv recv; 9001 => recv.port; recv.listen(); recv.event( "/test, f" ) @=> OscEvent t; // infinite event loop while ( true ){ <<<"sending">>>; xmit.startMsg( "/sndbuf/buf/rate", "f" ); 0.5 => xmit.addFloat; 0.2::second => now; //send something t => now; // wait for event to arrive // grab the next message from the queue. while ( t.nextMsg() != 0 ){ <<<t.getFloat()>>>; } }

no devices found

hi i am new to chuck. I am trying to run it on Linux (Debian unstable) but i get this error: $ chuck foo.ck [chuck]: (via rtaudio): no devices found for compiled audio APIs! [chuck]: cannot initialize audio device (try using --silent/-s) I tried on window goes fine. But my main production system is debian. However i am not expert on setting linux audio, still learning slowly. I installed ChucK with apt-get and i have version 1.2.0.7.dfsg-1 any ideas? thanks enrike

you need to use cast say you have a float variable space and you want to convert to integer discrete: space % int => int discrete; hope this helps brian > > From: "Laurie Hollander" <catbird451(a)gmail.com> > Date: 2006/11/03 Fri PM 09:18:25 EST > To: chuck-users(a)lists.cs.princeton.edu > Subject: [chuck-users] Float to int > > Sorry for the low level of this question, but.... > I'm trying to convert a floating point number to an int so I can chuck > it to the blit harmonics parameter.

Float to int
by Laurie Hollander 03 Nov '06

03 Nov '06

Sorry for the low level of this question, but.... I'm trying to convert a floating point number to an int so I can chuck it to the blit harmonics parameter. I've already used the math floor function on it, so it can be converted to an int without losing any information. But I can't chuck it to an int without getting error messages, and I can't find any function that converts a float to an int in mini-Audicle or Chuck. Is there a way to do this? Thank you! --laurie

Panic button?
by Ollie Glass 31 Oct '06

31 Oct '06

Related to Brian's question "how do you completely kill the audio from a shred in code?", is there a 'panic button' type command to completely kill all audio from chuck? Could be a useful feature. Ollie

Sounds spot on and I'd expect it to work, just wondering if there might be a need for some under the hood control to kill the engine. Hopefully not!

Re: [chuck-users] question about sporking

the code is up at the chuck forum at electromusic.com. i decided to separate the functions into separate .ck machines. everything worked perfectly then. Machine.add and Machine.remove. but when they are put all together and sporked in code, when removed, the notes stop processing but the last processed sample ran on for ever. actually, i tried unchucking the ugens at the end of the function and it still happened. but when called from .ck files on disk with machine.add and machine.remove everything was fine?!? i am using linux, ubuntu. alsa build. i believe this is a weird 1.2.7 bug that has something to do with my platform or hardware. brian > > From: Spencer Salazar <ssalazar(a)CS.Princeton.EDU> > Date: 2006/10/30 Mon PM 06:49:18 EST > To: ChucK Users Mailing List <chuck-users(a)lists.cs.princeton.edu> > Subject: Re: [chuck-users] question about sporking > > This is a strange problem... perhaps you could send some small > snippet of chuck source that reproduces the issue? > > One idea that might be worth trying is doing an un-chuck on all of > the shred's ugens from the dac before killing that shred.

question about sporking
by babiakb＠bellsouth.net 30 Oct '06

30 Oct '06

I sent a message earlier today but didn't see it. if it comes through twice for some reason, forgive. My problem is this: I spork a shred in code. I do this with a reference, like, spork ~ function () @=> Shred @ reference then when it's time to remove, i use Machine.remove( reference,id() ); the problem is, with oscillators and stks, the shreds do not stop audio cleanly. for example, when i have phasor => lpf => dac and remove the shred, the notes stop, but a high pitched tone lingers. also, when BlowBotl => rev => dac and remove the shred, the notes stop, but a medium pitched noise sound lingers forever. the time is synchronized to beat with now % T etc. I tried chucking and unchucking the ugens at the end of every loop. i tried with machine.add and remove from file instead of spork. i tried setting the gain and freq to zero at the end of every loop, but all these methods result in lingering sound. how do you completely kill the audio from a shred in code? any help? thanks in advance, brian

stk Ugens between 1.2.0.6 -> 7
by Graham Coleman 30 Oct '06

30 Oct '06

ChucKtivists, I'm having a problem with some of the Stk Ugens in 1.2.0.7-- certain Stk instruments no longer seem to play. Originally I noticed the problem in audicle 1.0.0.4 from 1.0.0.3. I prepared musical material for a local music competition using ...3 to be risk averse, but ...4 doesn't seem to play the parts using these instruments. Then I tracked it back to chuck. testStk.ck should demonstrate the basic problem-- if you are subject you may only hear one scale by one instrument (1.2.0.7) testStkAll.ck tests the whole gamut of StkInstruments. I have not yet tested the STK Ugens that are not StkInstruments. I'm on win32 and using lots of deprecated names, but hopefully neither make a difference. has anyone else seen this? best, Graham
