ChucK for live musicians
by joe higham 21 Dec '13

21 Dec '13

hi @ chuck-users lists I'm busy following the Coursera ChucK course provided by CAL Arts. As a live musician I was hoping to discover how one could use ChucK live (in the same way as Pure Data, Max/MSP etc). We've seen Ajay Kapur (whom I'm sure you all know) using his sitar in a live concert video made at CalArts, but no explanation followed. Unfortunately it seems that the course isn't going to cover this topic, so I've joined the list hoping people can help me out. Would it be possible to start giving me a few basic outlines for how to use ChucK via the adc (I'm a sax player). If you're interested (and if it works) here's a link to a thread created via CalArts and Coursera asking these questions: https://class.coursera.org/chuck101-001/forum/thread?thread_id=1429#post-77… You won't be able to comment but you will notice that we all wonder if one should pass via blackhole, if we should use a FFT etc. And more important, how? Thanks in advance Joe

Eclipse Plugin
by Alejandro Salas 15 Dec '13

15 Dec '13

Hello everyone, I don't know if this has been addressed elsewhere. I searched the archives and couldn't find anything. I was wondering if there was any initiative on creating a plugin for eclipse. I have some experience creating plugins for eclipse (although I haven't done any in a while), and I'm willing to help if necessary. Thanks.

Hello list, Is there a way to cast a dur (samples) to an int in chuck? This doesn't work: 1::second => dur pduration; pduration $ int => int srate; Thanks for your help! JPC

Thanks for any help you can give me; I'm looking forward to trying ChucK.

No simple vibrato example
by Manuel Bärenz 05 Dec '13

05 Dec '13

Hi guys, I'm giving a presentation on ChucK tomorrow and I wanted to show off some of the basic features in a live coding session. I found that creating a vibrato (modulating the frequency) is far too hard. The example I'm looking at is http://chuck.cs.princeton.edu/doc/examples/basic/whirl.ck. In an infinite loop, you have this code: 30 + ( Math.sin(t) + 1.0 ) * 10000.0 => s.sfreq; t + .004 => t; Here, t is a float and s is a SinOsc. Now, what I would have expected is the following, more intuitive setup outside the loop: 30 + SinOsc freq_mod => s.freq; 1 => freq_mod.freq; I know that the first line with the "30 + SinOsc" is probably nonsense in itself, but I could work around that (by using a step UGen for example). My actual problem is that you can't chuck a SinOsc into s.freq. Consider this line: SinOsc freq_mod => s.freq; I get an error like this: arguments type(s) do not match: ... for function 'SinOsc.freq(...)' ... ...(please check the argument types) Is this something that the language is simply not capable of or am I doing something wrong? Best, Manuel

MIDI-synchronization and metric timing (?)
by Blixa Barscheck 05 Dec '13

05 Dec '13

Hi, ChucK-Community! My name is Steve. So far I have been using Max 6 for MIDI-programming. My primary workflow is that I generate MIDI-data in Max and send them to my DAW where it's used to trigger several SoftSynths. I am the point now, however, where Max doesn't offer me enough flexibility to realize what I want to do. I am considering switching to ChucK. There is one thing, however, I need to know about ChucK: In Max I am able to synchronize it's timing mechanism to my DAW and define any kind of timing data (e.g.: frequency of an LFOsc) in metric timing (1/16-notes, 1/8-notes, etc.). Is this also possible in ChucK? If no, then ChucK unfortunately is no option for me, at least at the moment. Thanks! best regards, steve -- Diese E-Mail wurde aus dem Sicherheitsverbund E-Mail made in Germany versendet: http://www.gmx.net/e-mail-made-in-germany

PI Chucking contest...

So I'm happily agog at what it's really capable of. Do you have ChucK running on the RPI? And if so, what's a rough assessment of its performance, e.g. how many voices can it synthesize? - Rob

What does $ do?
by Gregorio Gomez 22 Nov '13

22 Nov '13

Hello, everybody: I've been looking at Michael Heuer's (most excellent) LiCK library. He uses an idiom that I don't see documented: intervals.get(i) $ Interval @=> Interval interval; from Arpeggiator.ck, line 35 https://github.com/heuermh/lick/blob/master/Arpeggiator.ck What does $ do? Of course just because I don't see it in the documentation doesn't mean it's not there, so please feel free to point me to the docs if I've overlooked it. Thanks! Greg
