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

Problem with multiple audion sources
by monon＠att.net 20 Nov '13

20 Nov '13

I am a new chuck user and have just installed linux-alsa from source. All works well as long as there is no other audio source active. If there is another active audio source active I get this message when, for example, I type in chuck --loop: [chuck]: RtApiAlsa::getDeviceInfo: snd_pcm_open error for device (hw:0,0), Device or resource busy. This seems to be a chuck issue as I can run multiple audio sources as long as one of them is not chuck. My concern is that I started a coursera course on chuck and would like to use chuck concurrently with the course. My operating system is Kubuntu Linux 12.04. Does anyone have any ideas? Thank you, Monon
