odd Hid behavior maybe just on OS 10.7
by Jeff Albert 09 Oct '12

09 Oct '12

Hi all, We are doing a piece in our laptop orch that uses Hid input from the keyboard and mouse. The group does not have matching machines. All but 1 are Macs, with the OS ranging from 10.6.x to 10.8.2. The code (pasted below) works on the windows machine and the 10.6 and 10.8 Macs, but not on any of the machines running OS 10.7.4. Thoughts?

dumb python question...
by forrest curo 07 Oct '12

07 Oct '12

Okay, I can easily get python to start a chuck shred... My question: What's the easiest way to let it feed that shred notes? -- rather than the burn-the-house-down kludge of killing the old shred, starting a new one with new command-line?

get hash keys from associative array
by George Locke 02 Oct '12

02 Oct '12

Hey, int hash[]; 0 => hash["zero"]; 1 => hash["one"]; hash.keys @=> string keys[]; Is there anything like this, some way for an associative array to tell you what keys it has? Ge apparently mentioned it as a development goal for 6 years ago ( https://lists.cs.princeton.edu/pipermail/chuck-users/2006-March/000436.html ), but searching for "key" in the versions page shows no update in this area. Thanks, George

Begin the beguine
by Alberto Alassio 30 Sep '12

30 Sep '12

Hi guys this is my first thread because I've download Chuck just yesterday night and I'm trying to make something with this today (yes we can!). Really nice world! I read something from the manual ( the beginning tutorial) and also downloaded chuck pages where objects and other things about language are written. The question is : how can I understand every single line of Chuck? And I'm gonna make an example: foo.ck example. I was looking at this and also to other ones to understand how they work but... I saw that there are objects that are explained in Chuck homepage (sinOsc, delayD, etc) but where can I find informations about Std? Hi?How can I understand what does Hi.cap mean? These are just examples, is there a place where every command is explained? Or maybe (and probably) it's just me not so good searcher? Thank you everybody Balbit

Looping
by Alberto Alassio 27 Sep '12

27 Sep '12

I cannot understand how the while structure has to be used. I mean, I understood that while ( true ) means infinite loop and also that while ( n::second => now ) means an "n" second loop duration but... If I just want to do a really stupid thing like a Sine at 220 Hz that sounds for 2 seconds and then stops for 2 seconds and then goes again. How could I do? I thought that it was necessary just to do something like this SinOsc s => dac; .2 => s.gain; 220 => s.freq; while ( 2::second => now) 0 =>s.gain but I know that it's not the right way, also because in this method I would have to rewrite this thing an infinite ( whiletrue ahahah) number of times to have what I'm looking for. And I don't actually understand {} . How am I supposed to use these? Thanks

1.3.1.2 (chimera) released!
by Ge Wang 21 Sep '12

21 Sep '12

Greetings all! chuck-1.3.1.2 (chimera) is available: http://chuck.cs.princeton.edu/ http://chuck.stanford.edu/ This release addresses some of the recent issues discussed on this list, includes 2 important bug fixes, and adds automatic sample rate detection for JACK as well as others. release notes are copied below. Once again, thanks to everyone who reported issues and helped to track things down and test! Please continue to let us know if you run into any issues! Thank you and keep on ChucKin'! Best wishes, Spencer, Ge + on behalf of chuck team! 1.3.1.2 --- - (added) chuck now automatically detects and uses next highest or closest (in that order) system sample rate in the case where the default is not available; if a sample rate requested via --srate: is not available, an error will be encountered with a message. - (fixed) base parent object is correctly accounted for by new shred when sporking member functions (thanks to Michael Heuer for reporting and narrowing this down) - (fixed) popping local variables from the operand stack in cases where the datatype size is larger than int-size; this is a bug introduced with 64-bit in 1.3.1.0, and exhibited on 32-bit systems only. (thanks to Simon Steptoe reporting and narrowing this down) - (fixed) opening real-time audio with 0 input channels should now work, once again.

Re: [chuck-users] STK instrument segmentation fault

Hi Ge, We met at SLEO. I'm using the newest chuck version: 1.3.1.2 (chimera) mac os x : intel : 64-bit. Re: FM sound Yes I recall reading a forum message that FM was an abstract class. Maybe a simple output message could inform users they need to subclass FM. Re: Brass sound I recorded and attached a small example of the Brass sound I get (BrassTest.mp3). To my ears it sounds distorted. (chuck code at end of email). Re: Mandolin ChucK plays correctly and seg faults when finished. This happens consistently on my MacPro.

BODY { font-family:Arial, Helvetica, sans-serif;font-size:12px; }ack.... oops!! so excited about firing up 64-bit chuck, i forgot about the 48k default sampling rate! chuck --srate44100 ....fixes everything. sorry for the noise... cheers! .pltk. On Sun 09/09/12 8:42 PM , plutek plutek(a)infinity.net sent: greetings! i just compiled 1.3.1 on a 64-bit linux system. compilation for jack went fine, and chuck runs without error messages. however.... no jack client is created. (so, of course, i hear nothing) shreds don't actually get started. (i.e. chuck ^ shows NOTHING) when i stop chuck, it says: RtApiJack::closeStream(): no open stream to close! if i run with --silent, incoming shreds DO show up. my jack is working fine with other applications. any clues? what shall i send to help figure this out? thanks much... cheers! .pltk. _______________________________________________ chuck-users mailing list chuck-users(a)lists.cs.princeton.edu [1] https://lists.cs.princeton.edu/mailman/listinfo/chuck-users Links: ------ [1] mailto:chuck-users@lists.cs.princeton.edu
