Sporking class member causes NullPointerException?
by nitro2k01 28 Jun '06

28 Jun '06

I tried this: class Test{ 0=>int iz; fun void initTest(){ while(true){ <<<iz>>>; ++iz; 10::ms=>now; } } spork ~ initTest(); } Test o; And got this: [chuck](VM): NullPointerException: shred[id=2:spork~exp], PC=[3] The same code works perfectly when putting the fun reference and spork outside of the class definition. Is there any way around this, iow a way to start a shred from a instanciated object? /nitro2k01 -- -----BEGIN 2ROT13 MESSAGE----- The blog of nitro2k01: <http://soundandcomplete.wordpress.com/> Sätt på ett par flipflops, vippa på rumpan och gör det här till en minnesvärd sommar! -----END 2ROT13 MESSAGE-----

++ return value
by Atte André Jensen 28 Jun '06

28 Jun '06

Hi I expected the ++ (and --) operator to work as this: If ++ precedes the variable, e.g. ++i, the value returned is the value in counter after it has been incremented. If ++ follows the variable, e.g. i++, the value returned is the value in counter before it has been incremented. This doesn't seem to be the case (chuck always returns the value after it has been incremented): int i; <<<i>>>; <<<i++>>>; <<<++i>>>; [atte@aarhus tests]$ chuck increment.ck 0 :(int) 1 :(int) 2 :(int) Maybe this could be changed? -- peace, love & harmony Atte http://www.atte.dk | quartet: http://www.anagrammer.dk http://www.atte.dk/gps | compositions: http://www.atte.dk/compositions

instruments extending StkInstrument
by Atte André Jensen 27 Jun '06

27 Jun '06

Hi I'm still quite new to chuck, but after going through the "Notes on Chuck for music" tutorial it struck me that a nice way to (over time) build a library of instruments that work in an interchangeable way would be to extend the StkInstrument. Instruments build this way should work like the StifKarp instrument used in the tutorial. I realize that this in some/most cases comes of fine grain control of the sound, but thinking about it that's the way I prefer thinking about instruments; encapsulated sound generating units. For instance I have over time build a library of over 100 midi-controlled realtime csound instruments that I use all the time. It this a recommended way of making instruments? Any documentation or examples on how to do this? How much slower would a userspace implementaion be compared to the buildin instruments? Would it be possible that such user defined instruments could make it into the language itself, and how much is involved in converting a userspace instrument into a build-in instrument? -- peace, love & harmony Atte http://www.atte.dk | quartet: http://www.anagrammer.dk http://www.atte.dk/gps | compositions: http://www.atte.dk/compositions

newbie questions
by Daniel L Trueman (dtrueman＠Princeton.EDU) 27 Jun '06

27 Jun '06

ok, newbie chucker here, with dumb questions: 1. is it true that the archives for this list are not searchable? i would be most delighted to avoid asking dumb questions by searching the archives first. 2. confused is me trying to set some STK time parameters. for instance: // noise n => ADSR e => dac; 400::ms => dur t => e.attackTime; // doesn't work, which is ok since i know: // .4 => e.attackTime; // does work, but it would make more sense to me to be able to send durs around consistently, especially when i see something like this: // noise n => Envelope e => dac; std.rand2f(10,500)::ms => dur t => e.duration; // that works. now, things become more mysterious when i find that "duration" is not documented online as part of Envelope, which makes me wonder if i'm missing something, and also wonder what other interesting things remain undocumented. is it just that some of the STK ugens have been extended to take durs, but not all? most joyfully attempting to chuck, dan

putting samples in array
by Atte André Jensen 27 Jun '06

27 Jun '06

Hi I've got a breakbeat that I chopped up at every 16note. Now I'd like to play these samples one after another. Could set up 16 sndbuf's each connected to the dac, but wouldn't that be inefficient? I'm thinking it might be smarter to load the samples into an array and play a different one on each pass, but is this possible. Or whould there be a really bright way to go about this? -- peace, love & harmony Atte http://www.atte.dk | quartet: http://www.anagrammer.dk http://www.atte.dk/gps | compositions: http://www.atte.dk/compositions

upload .ck files to wiki
by Graham Percival 24 Jun '06

I have three ChucK programs I'd like to upload to the wiki (ChucK/Programs), but the Special:upload seems to only accept graphics. Is there any way to add these files other than making new pages with the code? Cheers - Graham Percival

My app isn't open source. Is it okay to distribute ChucK with it? Sorry if this seems like an obvious question, I'm not very clear on licences and don't want to make a mistake.

I'd like to distribute ChucK with my app, saving users from downloading it seperatly. Is it ok to do this? Thanks, Ollie
