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

chuck + PulseAudio (was: Problem with multiple audion sources)
by Spencer Salazar 14 Nov '13

14 Nov '13

Hello ChucK linux users, We are excited to have a beta version of chuck that features PulseAudio support! While PulseAudio is not always ideal for professional audio usage, we absolutely recognize that its a popular choice for general-purpose Linux installations. We would love it if Linux + Pulse users could try out the beta and report any feedback, issues, etc. ChucK source (version 1.3.3.0-beta-3): http://chuck.stanford.edu/release/files/beta/chuck-1.3.3.0-beta-3.tgz miniAudicle source (version 1.3.1-beta-3): http://chuck.stanford.edu/release/files/beta/miniAudicle-1.3.1-beta-3.tgz Thanks, spencer On Wed, Nov 6, 2013 at 1:12 AM, Harald <hg42(a)gmx.net> wrote: > pulseaudio should usually work out of the box because most linux desktop > distributions have this installed and configured, so it should be nice for > beginners. > > But musicians etc. / linux music distributions usually use jackd. > > Apart from that alsa allows to create virtual devices to be routed through > pulse or jack for those who know how to do it. > So alsa would be a good choice for all, but unfortunately desktop > distributions don't come with alsa on top of pulse (from what I remember). > > So there should be a choice between all these systems, probably with > default to pulse and a BIG comment at a prominent place saying latency etc. > may be bad and using jackd would be better.

[MiniAudicle] Minor bug with editor
by Pierre Faure 11 Nov '13

11 Nov '13

Hi, I recently acquired a late 2013 Mac Book Pro running Mavericks. While working on MiniAudicle on this computer, I noticed a few problems, all bypassable, but annoying nonetheless. First of, while using non ascii characters, like ‘é’ in strings. I made a program that looks up samples, and their name is hardcoded in the script, e.g. « réso1.wav ». When I save the file for later use, and load it up again, the ‘é’ are gone, the editor displays « reso1.wav ». My files are therefore not accessed. I don’t think that is normal, as on my Windows PC, non ascii characters are accepted. Secondly, when I paste from the terminal (like a folder path), the editor uses whatever colors my terminal background is set in. I use black, so when I paste, the background of the pasted line becomes black. Lastly, here’s an error message I get from the console window. 2013-11-11 18:14:31.318 miniAudicle[662:707] *** WARNING: -[NSImage dissolveToPoint:fraction:] is deprecated in MacOSX 10.8 and later. Please use -[NSImage drawAtPoint:fromRect:operation:fraction:] instead. 2013-11-11 18:14:31.318 miniAudicle[662:707] *** WARNING: -[NSImage dissolveToPoint:fromRect:fraction:] is deprecated in MacOSX 10.8 and later. Please use -[NSImage drawAtPoint:fromRect:operation:fraction:] instead. Again, those are minor problems. Best regards, Pierre FAURE

Trouble with Machine.add() and paths on Windows; listing loaded shreds
by Gregorio Gomez 31 Oct '13

31 Oct '13

Hi, everybody: I'm new here. I'm really intrigued with ChucK and I'm looking forward to working with it. I am having one problem. I've taken a look at the list archives, and the forum, but the fixes I've seen there haven't worked for me. If there's something there that I overlooked, I apologize. Please feel free to point me in the right direction. Basically, I'm having some trouble including the LiCK library, but my questions are more about Machine's add() method. Here's an example of what's not working: Machine.add("c:\\Program Files (x86)\\ChucK\\libs\\lib-master\\BinaryFunction.ck"); And the errors: [chuck]: unrecognized escape sequence: \P [chuck]: malformed filename with argument list... My questions: When Machine.add's argument is a relative path like this: Machine.add("BinaryFunction.ck"); or this: Machine.add("libs/BinaryFunction.ck"); what's the path relative to? What's the correct way to use absolute paths in Windows? What's the correct delimiter for paths in Windows? Is it possible to get Machine to list loaded shreds? I'm running: Windows 7 miniAudicle 1.3.0 ChucK 1.3.2.0 Thanks! Greg

miniAudicle issue
by Morgan 28 Oct '13

28 Oct '13

Hi there, I am trying to get miniAudicle/chuck running on my reasonably fresh install of Linux mint KDE. I have a MB with onboard Audio which is what I have plugged up to my speakers and is set as the default audio device in my system settings.. My audio works smoothly for other things such as mp3, flac and orb playback, MIDI (suck as linux MM Studio). I do not have jack installed. I went through the process of installing all of the dependancies, compiling and making the installs, though i dont know if there was an order i was meant to do it in. I have been trying to trouble shoot... I have run from the terminal ~ > lspci | grep audio 0a:0c.0 Multimedia audio controller: Creative Labs SB Audigy (rev 04) ~ > chuck --version chuck version: 1.3.2.0 (chimera) linux (alsa) : 32-bit http://chuck.cs.princeton.edu/ http://chuck.stanford.edu/ On initializing miniAudicle the console reads - [chuck]:(2:SYSTEM): setting log level to: 10 (ALL!!)... [chuck]: RtApiAlsa::getDeviceInfo: snd_pcm_open error for device (hw:2,2), No such device. then when i click start virtual machine the program hangs up (whether or not I have a shred in the Audicle window.) Sometimes it will give me an error message about an infinite loop, even without any shreds? I am pretty stumped right now... i have been googling but cant find anyone have the same issue. Morgan
