Mac OS X Lion support
by Spencer Salazar 19 Aug '11

19 Aug '11

Hello, As many have already noticed, the current release version of ChucK does not run in real-time audio mode on Mac OS X Lion. Until now! In advance of a formal release, we are providing builds of the current SVN source for anyone who is having trouble getting ChucK to run on Lion. ChucK (Mac OS X Universal command line executable): https://ccrma.stanford.edu/~spencer/chuck/chuck-1.2.1.4-beta-1.tgz miniAudicle (Mac OS X Universal binary): https://ccrma.stanford.edu/~spencer/chuck/miniAudicle-0.2.1-beta-1.tgz Lion users, please let us know if you continue to have difficulties with real-time audio with these builds. Updating ChucK to use the latest version of RtAudio fixed a host of Lion issues; a minor bugfix in RtAudio resolved the remaining issue. There are a lot of other cool things coming too when the new version of ChucK is released. Special thanks to Gary Scavone for making peace between Mac OS X Lion and RtAudio. Peace! spencer + chuck team

i went into terminal and did exactly what you said. when i entered "%>chuck" in the terminal it didnt give me the "[chuck]: no input files... (try –help)" message on the terminal screen like it says it should in the chuck manual. does this mean it didnt install correctly? i included a pic of the terminal windo as well. i dont know how to tell if its installed or not. thanks so much for your help.

Oops, I see that you did navigate to your downloads folder correctly. Just to be sure, you didn't type "%>chuck" did you? The "%>" is meant to represent the computer's line prompt. All YOU have to type is: chuck and hit enter. Now do you get the whole "no input files" thing?

Does the miniAudicle work for you? Because that's the most straightforward way to use ChucK. Certainly if you're mainly interested in programming for the Monome, the miniAudicle is the best environment. The installation of the command-line version is generally only necessary for special cases. If you're really intent on using the command line version, I suspect that it's navigating to the chuck folder in the terminal that's tripping you up. Where is your chuck-1.2.1.3-exe folder? If it's on your desktop, then you'll need to type: cd ~/Desktop/chuck-1.2.1.3-exe/bin (likewise, if it's in your Downloads folder, replace Desktop above with Downloads) then: sudo cp chuck /usr/local/bin (Just to echo Hans' comment, you don't need that line about 'sudo chmod 755...')

ive been interested to try out chuck as a programming language for my monome, but i seem to be having some difficulties with the installation. im on a macbook pro 10.6.8 btw. i downloaded the chuck executable as well as miniaudical. i opened up the chuck executable which opened up a chuck folder with a bunch of things in it, and i stored them both in my applications folder. in the chuck manual, theres a section i included in an attachment that talks about replacing the x's with the actual "directory name". what is a "directory name" and how do i find out what my directory name is? id really like to get this going, thanks in advance for any help! hopefully i ll be chucking soon.

MIDI Forwarding?
by Johnathan Bell 26 Jul '11

26 Jul '11

All, I was looking at Ableton to do this, but I think I may be able to achieve a cheaper and better solution using ChucK ... I want to forward MIDI messages from a USB-MIDI keyboard, through a computer, to a hardware synth that has the standard MIDI in/out ports. My keyboard does MIDI over USB, but has no standard MIDI ports, so I can't plug it directly into a synth, but if I were to use a USB MIDI interface on my computer, could I interface the keyboard to the synth that way, using ChucK as a go-between? It'd be a simple matter of opening the MIDI in from the keyboard, and then just copying those messages to the MIDI out of the interface, I'm thinking... - Johnathan

Hello, my first post here, so please excuse me if I'm doing something wrong. I installed the latest version of chuck on my 10.7 system, and I am facing this issue: go-vegan:basic Jonas$ chuck demo0.ck [chuck]: (via rtaudio): no devices found for given stream parameters: ... RtApiCore: No supported sample rates found for OS-X device (Apple Inc.: Built-in Output). ... RtApiCore: No supported sample rates found for OS-X device (Apple Inc.: Built-in Input). My sample rate is 44100, and I didn't change it since the Snow Leopard (where ChucK worked without any problem). Anyone else having this problem? Or can think of solution? Regards, Jonas

I mean, I imagine that downloading and compiling the new version of rtaudio isn't enough, the link with ChucK would be missing. It looked as though the old RTaudio files in ChucK should be replaced by the new one; then recompile. That is, Chuck does not call RTaudio library but uses the sources. But if that proves complicated, it should be possible to install RTAudio as a library, take away the old sources from 'chuck', and the make sure the rtaudio library is included when linking (say by tweaking the chuck Makefile). That does not result in a standalone binary, though., but you will know if it fixes the problem. Hans

Chuck in OSX Lion
by Carlo Giacometti 23 Jul '11

23 Jul '11

Hi everybody, I've been using Chuck for a couple of weeks, it's great! I compiled version 1.2.1.3 on Snow Leopard 1.6.8, and everything worked perfectly. Yesterday I upgraded to Lion (bold move, I know), and what I get compiling a simple program which always work is: ... RtApiCore: No supported sample rates found for OS-X device (Apple Inc.: Built-in Output). ... RtApiCore: No supported sample rates found for OS-X device (Apple Inc.: Built-in Microphone). ... RtApiCore: No supported sample rates found for OS-X device (Apple Inc.: Built-in Input). [chuck]: cannot initialize audio device (try using --silent/-s) Furthermore, this is what I get with the command --probe: [chuck]: found 3 device(s) ... [chuck]: ------( chuck -- dac1 )--------------- [chuck]: device name = "Apple Inc.: Built-in Microphone" [chuck]: probe [failed] ... [chuck]: [chuck]: ------( chuck -- dac2 )--------------- [chuck]: device name = "Apple Inc.: Built-in Input" [chuck]: probe [failed] ... [chuck]: [chuck]: ------( chuck -- dac3 )--------------- [chuck]: device name = "Apple Inc.: Built-in Output" [chuck]: probe [failed] … What should I do? Is it an easy fix, or the best solution is to downgrade (not my preferred option, though)? Thanks, -- Carlo Giacometti Sent with Sparrow (http://www.sparrowmailapp.com)

From 4Hz to 400Hz
by Rustom Mody 17 Jul '11

17 Jul '11

Just compiled chuck -- its power seems quite exciting! Why I am looking at chuck: I am preparing to give a talk on the wider ramifications of music. One of the things I wish to demonstrate is that things that look different are often merely analogs but at different scales. eg if something vibrates at 400Hz we hear a sound of A-flat. If it 'vibrates' at 4 Hz we hear a beat. In the same analogy a 2 vs 3 poly-rhythm (should?) change to a do-so chord. And so on. Or stated in reverse: Say I have a rhythm in 4/4 time -- 4 even quarter notes, bar repeating every second played by say a click. [What kind of click I am not very sure; sharp with few harmonics would be best I expect] Now if there were some (realtime) way of sliding the tempo from 1 sec to millisec I expect the separate clicks would vanish into a hum at some stage. This (and other such experiments) is what I want to demo. Can I do this with chuck/miniaudicle? PS. I have some issues with my setup which I will post separately. But first I need to know whether I am using the right tool.

interval keyboard
by Michael Heuer 12 Jul '11

12 Jul '11

Hello ChucKers, I wanted to emulate something I saw on youtube once (sorry, I've lost the link), an interval keyboard where keys on the right hand play notes increasing by various intervals and keys on the left hand play notes decreasing by various intervals. I haven't any music theory and the wikipedia pages for muscial intervals are over my head. http://en.wikipedia.org/wiki/Interval_(music) http://en.wikipedia.org/wiki/List_of_musical_intervals My question is this, what should the method on Interval be called that "inverts" it (from low-to-high pitch to high-to-low pitch)? https://github.com/heuermh/lick/blob/f49ddd8285ee412f9b6c05c2ef5ba6c6cdb543… I have learned that is not the same as an inversion, which does something else to ratios https://github.com/heuermh/lick/blob/f49ddd8285ee412f9b6c05c2ef5ba6c6cdb543… The example is here if you want to give it a try https://github.com/heuermh/lick/blob/f49ddd8285ee412f9b6c05c2ef5ba6c6cdb543… Cheers, michael

I'm writing a program that talks with Wekinator, but I'm having a problem with sending the feature names over OSC that I'm fairly certain is a problem with chuck. At the bottom of the code (see bottom of email) is the relevant method, sendOscFeatureNames(). When I run wekinator and get to the training screen, I run this code. The instant it sends the feature names to Wekinator (i.e., the instant it is run), an exception gets raised: " Exception in thread "Thread-4" java.lang.ArrayIndexOutOfBoundsException: 1536 at com.illposed.osc.utility.OSCByteArrayToJavaConverter.lengthOfCurrentS tring(Unknown Source) at com.illposed.osc.utility.OSCByteArrayToJavaConverter.readString(Unkno wn Source) at com.illposed.osc.utility.OSCByteArrayToJavaConverter.readArgument(Unk nown Source) at com.illposed.osc.utility.OSCByteArrayToJavaConverter.convertMessage(U nknown Source) at com.illposed.osc.utility.OSCByteArrayToJavaConverter.convert(Unknown Source) at com.illposed.osc.OSCPortIn.run(Unknown Source) at java.lang.Thread.run(Unknown Source) " This exception is not thrown when I replace numDataPoints[i] with a constant (like 5).

ICMC-unConf
by Scott Hewitt 06 Jul '11

06 Jul '11

Hello, Please except my apologies about cross posting, however I have submitted an idea to the unconf concerning the use of ChucK and Git version control http://icmc-unconf.inclusiveimprov.co.uk/doku.php/unconf/proposals/chuck-an… This message is being cross posted to further publicise the Un-Conference events running along side the 2011 ICMC . . . http://icmc-unconf.inclusiveimprov.co.uk/ This year’s International Computer Music Conference is being hosted by the University of Huddersfield, Sunday July 31 -- Friday August 5 ( http://icmc2011.org.uk ) The unConf features presentations, discussions and conversation on Monday 1st August and Tuesday 2nd and Gigs on Sunday 31st July and Wednesday 3rd. What’s an unConf? Its a conference without the formality and fixed proceedings. If you have something you want to discuss or present then head online and submit an idea otherwise turn up on the day and start a conversation, best thing about attending the unConf is it is free of charge. While it is not formally part of the conference the unConf does give a great opportunity to meet with international practitioners. Hope to see some of you there, ii

avoiding lag
by Timothy Leonido 27 Jun '11

27 Jun '11

Hey All, Is there a way to ensure that two patches will synch properly? Sometimes the simultaneous chucking of two heavy patches will cause a lag: one will be set back .5::T behind the other. I tried machine add for this, but ran into the same problem. Thanks, as always, & nice weekend, Tim

documentation: pdf totextplain and speech synthesizer

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 i have the pdf version of the chuck manual, very nice that, though because i'm using a speech synthesizer, the easier thing for me is to convert to text and to read that way, either that or old habits die hard, i haven't played with pdf and text access with speech lately, it might have gotten better since early 2000 when i toyed with it last. anyway, enough of that, i want to make the pdf manual text, however when i do so it doesn't appear to convert properly for some reason. it is hard to follow directions and learn from tutorials when the text isn't exactly what was intended. am curious if anyone else has encountered this or a solution for such. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJOButJAAoJEIaKvi7tbzRHPl8H/AtbTuUgc7cv3McTdjrg6U+c HkM9olDQ5TdFLTCcVBThg4xQ2Gd5vKaCRnea0rc5b4TQ2qLbOWlxdLvzSCGYxOBr SH+7QEUnfr6Q7Ko7dHpZDfXBP2bjK/dBw+MgKukIZ1uFN7D8WtUHH4uMDGeRFcxT bwU5lFadDP6rCrU1zPFu5iwXLM7Fc6x1QXXpA8ZdM5Vf4bUDll+JoVweVj/VtH4P 7KN3PCkV/ZzzjaeWcPhYNJfHPKgbMKOutKfsC/P/manoevi1XwltsnUKfVB1aE7u EUM9mHur7fBRwgyJ/m6SIV3a1vNYRs1/4BXjIStT6N2SWpJH+Z8E4Rl1w4oheso= =A6dJ -----END PGP SIGNATURE-----

by mike clemow 20 Jun '11

20 Jun '11

Hey Chuckists, So, I find myself in Prague for work and I would love to see some electronic music / meet Chuck people / even get a gig (?) while I'm here. Any advice / ideas / contacts? I've been here for a week and a half, and I'm here until July 5th. If any of you will be in the Czech Republic, please holler. Best, Mike -- http://michaelclemow.com
