chugins
by Kassen 25 Aug '12

25 Aug '12

Hey Spencer! I thought I'd send this to you through the list because it potentially affects others. I'll explain things you already know for them. You'll remember I (like Caspar) did a ChuGin for testing and fun. I wrote it, which wasn't very hard; nearly everything in the C++ that is unlike writing your own DSP in a ChucK Shred could be copy-pasted. After verifying that this worked and was fun I wrote some documentation for it so that others could enjoy it and I seem to remember I slapped the GPLv2 on it so that they'd be allowed to enjoy it in any way I'd call reasonable. All in all a nice package... But let's be honest; I'm no C++ wizard, English isn't my first language and I can generally be a bit distracted; there are quite possibly a issue or two with it. Back when I send it I asked for opinions but while we are being realistic; you probably have a lot of other things to review too, things that probably do have deadlines. Currently my "KasFilter", which is supposed to be a fun "non-clean" filter especially suited for kinds of music with a low-aesthetic that need a prominent filter, doesn't seem to be centrally distributed. I'd like it to be so I'd like to talk about how we can address the above in a way that makes everyone happy. For that I'd be perfectly willing to run tests, change stuff, etc and generally be a guinea-pig for such a process. If we don't I can host it too, but then I foresee having to maintain a list of links to ChuGins that people made, with all of the inconveniences that might bring. What I could for example do is make a GitHub account and request privileges to push my work into your repository? That'd centralise stuff though not everyone who'd like a few new UGens might be comfortable with Git and make. Yours, Kas.

Comprehensive ChucK performance source code [was soft kill]
by Robert Poor 20 Aug '12

20 Aug '12

By the way, I posted my entire live ChucK setup on github. This includes the ramping down a patch when switching to another: https://github.com/rdpoor/chuck_performance_setup It's sparsely documented but very cleanly structured, and it's been performance-tested and debugged. I'm happy to document additional bits upon request. Perhaps the most important starting point to know is that it uses an Oxygen8 keyboard and a Game Trak "6 axis" controller as inputs. - Rob

soft kill
by Michael Heuer 19 Aug '12

19 Aug '12

Hello, I was having some fun with delays in ChucK when I should have been paying attention in a meeting and ran into something I may have asked about before -- is there (or should there be) any way any way to soft kill a shred, either by ramping down its gain or by waiting until the shred is no longer sending output to dac? If I $ chuck - 1 something that is running it kills it immediately, and if I don't advance time long enough explicitly at the end of a delay example, the nice feedback tail gets abruptly cut off. E.g. https://github.com/heuermh/lick/blob/master/examples/mfm2.ck (doesn't require LiCK to run) michael

Coin in Chuck
by ronni montoya 19 Aug '12

19 Aug '12

Hi , in supercollider there is a number method called coin. It just gives you back true or false based on probabilities. For example: 0.2.coin; -------------> this means 20 % chance for true. So if i do : if(0.2.coin,{ doSomething(); }); The function is gonna have 20% change to be called each time i run that code. Is there is something like this in chuck? cheers. R.

Insteresting sound when playing 2 or more instances at the same time.
by ronni montoya 18 Aug '12

18 Aug '12

Hi list, when i play 2 or instances of the same code it generate wierd results, it adds new sounds to the existing sounds. Do anybody have any idea whats the reason of this. Is this because some kind of lack in the memory? Any idea of how to replicate this sound from inside chuck Thanks Try this code 3 times and your are gonna listen rythmic patterns , for example: chuck chuqui.ck chuqui.ck chuqui.ck here is the code: Step s => dac; // modulator SinOsc m => blackhole; 0.00052 => m.freq; SinOsc g => blackhole; 0.0082 => g.freq; SinOsc t => blackhole; 0.00055 => t.freq; 6 => float v; 6 => float k; 6 => float n; fun void sample_manipulation( ) { 0.002 + k => k; 0.0002 + n => n; 210 * (now/ samp) => Math.sin => Math.tan => v; if (v > Math.sin(k / 5) + 0.95) { v + Math.sin(k / 10) => k; 0.008 * 10 / m.last()=> k; } if (v < Math.sin( k) + 0.3) { -0.2 * 2 / g.last() * t.last() => v; } if (v < 0.2 ||v > 0.8 ) { v + Math.sin(n / 25) => v; } v + ( v * 10 ) / m.last() * Math.atan( m.last() ) => v; v * ( v * 100 ) * m.last() * Math.asin( m.last() ) => v; } while (true) { sample_manipulation ( ) ; v => s.next; 1::samp => now; }

Re: [chuck-users] chuck vs supercollider?
by Perry Cook 13 Aug '12

OK, I'll chime in here. Both languages are Turing complete, so anything logic- wise can be done in either. The ability to compute control, physical simulations, and/or samples at any time resolution, even sub sample, is super powerful from an experimental and philosophical perspective. Single sample computation does allow for feedback, and even parallel patches, that are not possible or indeterminant with vectorized (block), computation. And even delay-free loops (needed for some algorithms, like physical simulations) can be more accurately approximated with sub-sample computation. Efficiency is an issue. A more appropriate Ge quote, which came from Paul Lansky, is "never optimize." Ge set out to make ChucK unlike any other language, and efficiency was not a priority. Roger Dannenberg even was swayed, stating that ChucK isn't that inefficient, especially given the power it gives the programmer. One other really nice ChucK tool is the MiniAudicle. Some don't care for it, or don't see the point, but having a smart editor, monitor, shred manager, etc is reall powerful for development and real-time live coding. I don't know if SC has such a real-time IDE.

Sometimes I'll create a bunch of synths in SC that can be triggered by OSC and use Chuck as a score language. If I'm doing a lot of string/data processing, then I'll use Python to trigger them. But that's part of my practice, since many of my pieces involve interesting bits of hardware, I have to utilize OSCulator, SC, Chuck, and Puredata all for one piece of music. > > So, for the sake of completeness, I'll back the notion that you don't actually have to make an exclusive choice between environments. ;) The right tool for the job, right? > > -Mike > > -- > Michael Clemow > > http://michaelclemow.com > http://abattoirprojects.com > > > On Friday, August 10, 2012 at 7:33 AM, Kassen wrote: > >> On 10 August 2012 04:11, David Ogborn <ogbornd(a)mcmaster.ca (mailto:ogbornd@mcmaster.ca)> wrote: >>> Great answer - I'm going to save it and quote it whenever needed! :) >> >> >> Thanks Dan & David, >> >> Credit where it's due; this was more or less the conclusion of the >> debates I had with SC expert James 'DewdropWorld' Harkins. >> We found that the differences we and others with some expertise noted >> didn't really matter at all for those picking up either language. >> New users (who adopt either) simply seem to find that one is quite >> straightforward and the other doesn't make a lot of sense.

comparing fm in chuck an sc3
by ronni montoya 13 Aug '12

13 Aug '12

Hi, I was trying to recreate a simple fm synth in sc3 and chuck , so i can be able to compare the sounds of both. Is there any sc3 users in this list? i ve made this version of the fm code from chuck web site but it sounds so different. I was wondering maybe i made anything wrong? I was wondering also if doing this in chuck " m.last()" will be the same as "mod " in sc3? thanks. R. here is the code. Chuck: // FM synthesis by hand // carrier SinOsc c => dac; // modulator SinOsc m => blackhole; // carrier frequency 220 => float cf; // modulator frequency 550 => float mf => m.freq; // index of modulation 200 => float index; // time-loop while( true ) { // modulate cf + (index * m.last()) => c.freq; // advance time by 1 samp 1::samp => now; } Supercollider: ( SynthDef("fm1", { arg bus = 0, freq = 440, index = 200, mul = 0.05; var mod; var car; mod = SinOsc.ar( 550, 0, 1 ); car = SinOsc.ar( freq + (index * mod) , 0, mul ); Out.ar(bus,car) }).load(s); ) Synth("fm1");
