rec2.ck
by 2g 28 Aug '07

28 Aug '07

in another japanese chuck community i asked if somebody knows about "rec2.ck" which i cannot find in the examples dir and at last a person gave me the sample he found mm? this one seems to create 2 files instead of one stereo at this moment we cannot write stereo things to HDD? then i have to use sox to combine these maybe...? rec2.ck (not the original?): dac.left => WvOut wL => blackhole; dac.right => WvOut wR => blackhole; 4::second => dur l; now + l => time later; "./wavs/rec2L.wav" => wL.wavFilename; "./wavs/rec2R.wav" => wR.wavFilename; <<<"writing to file: ", wL.filename()>>>; <<<"writing to file: ", wR.filename()>>>; while ( now < later ) 500::ms => now; wL.filename() => wL.closeFile; wR.filename() => wR.closeFile; <<< "rec2 done." >>>; -- 2g http://micro.ispretty.com

what is this stk control change thing?
by Fitzpatrick, Denis F 25 Aug '07

25 Aug '07

My confusion is deep and multifaceted, but just to get started, I gather it's a way of setting various instrument parameters, but how does it differ from like-named (where they exist) method calls? I made a Googley effort to find this explained, but failed. I would gladly accept an answer in the form of a link.

CurveTable strange behaviour
by eduard 23 Aug '07

23 Aug '07

The following patch shows either a misbehaviour or a misuse of CurveTable, dunno. Two different functions (rand_coefs1 and rand_coefs2) are used to assign coefficients to CurveTable.coefs(). While the first seems to do the job alright, the latter doesn't and throws the following error message: [chuck](via CurveTable): usage: size, time1, value1, curvature1, [ timeN-1, valueN-1, curvatureN-1, ] timeN, valueN) Maybe I'm doing something wrong that | don't see, but can't understand why this happens. Could anyone explain? Also, don't understand why the error message tells me the size needs to be supplied. The examples say that coefs are arrays of the type [time1, value1, curvature1, ..., timeN-1, valueN-1, curvatureN-1, timeN, valueN] and Gen's size, if I'm not mistaken, is hard coded as 4096. Thanks in advance, eduard The patch: fun void rand_coefs1( CurveTable table ) { [-1, 0, 1 ] @=> int curvature[]; [0., 0., curvature[ Std.rand2(0, 2)], 1, Std.rand2f(.5,1.), curvature[ Std.rand2(0, 2)], 2, Std.rand2f(.5,1.), curvature[ Std.rand2(0, 2)], 3, Std.rand2f(0.,1.), curvature[ Std.rand2(0, 2)], 4, Std.rand2f(0.,1.), curvature[ Std.rand2(0, 2)], 5, Std.rand2f(0.,1.), curvature[ Std.rand2(0, 2)], 6, Std.rand2f(0.,1.), curvature[ Std.rand2(0, 2)], 7, Std.rand2f(0.,1.), curvature[ Std.rand2(0, 2)], 8, Std.rand2f(0.,1.), curvature[ Std.rand2(0, 2)], 9, 0] @=> float coefs[]; coefs => table.coefs; <<<"\n", "CURVE 1:\n" >>>; <<<"\t index", " value", " curvature">>>; <<<"\t----------------------------------","\t">>>; for( 0 => int i; i < 8; i++ ) <<<"\t",coefs[i++], coefs[i++], coefs[i]>>>; <<<"\t", coefs[8], coefs[9] >>>; <<<"\t----------------------------------","\t">>>; } fun void rand_coefs2( CurveTable table, int n_breakpoints ) { // this function does not assign values stored in coefs correctly to // CurveTable.coefs().

A example that needs correction
by Martin Ahnelöv 19 Aug '07

19 Aug '07

Hi! I was investigating what I could use the spork-keyword for when I stumbled on this problem in the examples: The example fm3.ck is pretty wrong. It says that fm-synthesis is at sync 0 on SinOsc's, but that isn't true. sync 0 is sync frequency. fm2.ck does it right however. Experience the difference yourself by changing both fm2.ck and fm3.ck's c.freq-variable. Anyways, this is the result of my tries: http://hauntedhouse.wordpress.com/2007/08/18/ambientic-monotonic-pieceus/ I'll probably go on and work a little more with it. Gasten

Re: [chuck-users] Lisa behaving strangely?
by Kassen 17 Aug '07

First of all, I seem to have inadvertedly send the message below to the dev-list which wasn't my intention. Oops. Secondly, sorry to reply to my own message and breach nettiquette but I found a second issue when trying to work around the one posted before. For some reason LiSa.duration() is write only. This is inconvenient when trying to work around this bug as it makes it impossible to go like this; l.playPos( l.duration() - samp); I can't realy see why duration would be write only while I can think of reasons to want to check the max duration of a buffer (aside from the posted bug). Could a readable version of .duration perhaps be considdered for a future update? Yours, Kas.

one of the two sX.freq() in a same while doesn't seem to get changed

today i learned about .5::second => dur T; T - (now % T) => now; and wanted to modify my isthisokay.ck to something more overtone sequencer oriented but nothing seemed to be working properly so comment outed a lot and went into the debug mode with the followings being chucked i can see things like s1 changed 34.747145 s2 changed 95.554650 s1 changed 56.208618 s2 changed 140.521544 s1 changed 32.703196 s2 changed 89.933788 s1 changed 45.988869 s2 changed 160.961041 --- get displayed but the sound itself doesn't seem to be doing this one of the two sinewave ... maybe s1.freq() seems to be playing the same long tone (freq never changing) and i don't seem to hear the rhythm pattern it should have created if am not wrong i think there is three sinewaves coming out isthisokay.ck: .5::second => dur T; T - (now % T) => now; SinOsc s1 => Gain g1 => dac; SinOsc s2 => g1; SinOsc s3 => PRCRev g3 => dac.left; SinOsc s4 => PRCRev g4 => dac.right; .25 => g1.gain; .25 => g3.gain; .25 => g4.gain; 27.5 * Math.pow(2.0,(3.0/12.0)) => float oilroot; 2 * oilroot => s2.freq; fun void ri() { while(true) { 300::ms => now; s2.freq() * Std.rand2(16, 32) / 16.0 => s3.freq; } } fun void ga() { while(true) { 330::ms => now; s2.freq() * Std.rand2(16, 32) / 16.0 => s4.freq; } } //spork ~ ri(); //spork ~ ga(); while( true ) { Std.rand2(32, 64) * oilroot / 32.0 => s1.freq; <<<"s1 changed", s1.freq()>>>; //1000::ms => now; 7::T => now; s1.freq() * Std.rand2(8, 16) / 4.0 => s2.freq; <<<"s2 changed", s2.freq()>>>; //250::ms => now; 1::T => now; } -- 2g http://micro.ispretty.com

experiencing that UB version (i don't know why but) works on osx10.3.9 i now understand that chuck is really what i wanted(RT-dsp@command-line) so wanted to go more CUI(VT) oriented and moved to linuxes on other volumes slackintosh was the only one i had to make(linux-alsa) by myself others got there by each apt oriented ways these are maybe cuz i didn't run jackd things before running chuck(is it?) but the result of each chuck moe.ck became as followings chuck on slack is alsa version but i don't know how the bin of debian&ubuntu got compiled (oh unstable is saying something related to jack..) any suggestions? tia slackintosh12.0: [chuck]: (via rtaudio): no devices found for given stream parameters: ...
