-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 right. while running through the directories in examples, what i would do is pull up the ck file on screen, try and figure out what it was trying to do and what it would sound like in my head, then i wouldn't change a thing, and execute the chuck command on that file, and see if i was right. an amusing way to learn chuck coding perhaps, though it seems to work for me. anyway, this deals with the file in the deep subdir called unclap.ck, that seems to give me a 'program has caused an error' dialog box, and options to submit the error or not. in other words, file not run. and the most amusing part is i can't even guess why this might be. i can say that i'm using the windows version of chuck.exe, 1.2.1.3 i think it is. and can't think of anything else to put in here. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJONPeuAAoJEIaKvi7tbzRH80gH/2kEF19jw7yqCq6SDefcS7Sa D/J3bwHi5fsMBJMI/k84ZWS7wmYy2STXLFXBomM0YHUbsQVlouzhS8ocV+Dul6u/ mkcYLqFlw0c6jTIRsr2S3HqLvdMtQQsvDEg5UjQ5PfpQulVh7BputHvDTAG7WkGq rREyCGdRsjmccmYwJyCJ1zxkgNyCT+8wYqJ2EH8uzBSBo6SaiTxgdKle3RM1Du/h 2ubzu/7yWdrzltpn0j084UX2DGra460Frcx90OcgvzB3n40VtcD5B1PahFW5stYD nCFL/Rsq3+G90C+EOTmJeSrOBVfsZS/CFLWljsIMp5BzeqTuJJ73OcWaPW6SUck= =/Skd -----END PGP SIGNATURE-----

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 i'd like to know if chuck has what i'm going to think of as arrays, that is for a variable foo, foo(1) is 4 foo(2) would be something else other than 4, and so on. then there'd hafta be a way to determine how many elements were in foo in the first place -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJOMLArAAoJEIaKvi7tbzRHdyUIAJE16MEAatNUKrnHCcFVqUlL 4wtYr+qs8KNaYeEKvtnTb0xx+QBBIMHSZvgaY2CApdtke8ocorRCufshFymHpWq7 jLBf60LqIdTIe93NL0y47VSMXwg5jQXMY5uaTNG7pzuWkjZBdm91md99cTnetAGk K7z9iVB5/8WZU5e4IsaS3aY2m9n55/pRisIc5Ot2lg4ZLy3E6dZJR83PPQdZYGIL ChBxhSJXrB/3rW7bue4Qznac5+muaMjq4TwuFQ/VQS0mU9xewqosSU2hq9/KJcbK K2WaPqMOgGt7ddK8qeEYdNfaGQ0c8jdSEluz1JuLkycyKJnZ1hojqfIwWJbkG0o= =2OWX -----END PGP SIGNATURE-----

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

chuck on os x 10.7 (lion)
by Jonas Zeleninsky 24 Jul '11

24 Jul '11

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

irc channel
by Jonas Zeleninsky 24 Jul '11

Hello, currently trying to analyze the digiio_rtaudio.cpp and I came to idea, that would be nice to have IRC channel where we can discuss issues more directly/hangout, deal with non-dev issues as well. is there one maybe? If not, I made one at irc.freenode.net called #chuck. See you there! 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.
