Bus Error - Trying to run ChucK for the first time
by jimmak cataract 13 Mar '05

13 Mar '05

Hello, I am an ultra-newbie trying to run ChucK for the very first time, and am experiencing difficulties trying to run any of the demos. The source compiled well on OSX 10.3.7, and trying to run ChucK without any input yields: [chuck]: no input files ...... (try --help) which is what the install readme says should happen (?). However, when I try to run any examples, for example demo0.ck, I get a bus error. The last paragraph in the console output says: JAR: DeviceSetProperty inSelf 17915232 JAR: DeviceSetProperty 'sfmt' JAR: Sample Rate: 44100.000000 JAR: Encoding: 1819304813 JAR: FormatFlags: 43 JAR: Bytes per Packet: 4 JAR: Frames per Packet: 1 JAR: Bytes per Frame: 4 JAR: Channels per Frame: 1 JAR: Bits per Channel: 32 time=0.0000s Bus error The jack server is running, and I have the same thing using portaudio as the driver (not coreaudio), as well as built in audio, and not my sound card. Could someone give me some direction in getting this to work? Thanks alot for your time, regards, Stuart Woolford. Australia. ChucK 1.1.5.4 dual 800MHz Quicksilver G4, 768 Mb Ram, Interface: Delta Audiophile 24/96 OSX 10.3.7 _________________________________________________________________ Searching for that dream home?

Windows XP crash
by Gary Williams 02 Feb '05

02 Feb '05

While testing my ModalBar program, ChucK crashed. I'm enclosing the program (mb419.ck) and the tech error text Windows produced (70d5_appcompat.txt). System Windows XP (with SP2) on a Sony Vaio laptop. Please let me know if you need anything else. --Gary ---- Chess: http://chessnut.net/ Homepage: http://garywilliams.org/ Blog: http://tfs_reluctant.blogspot.com/ ChucK Blog: http://b-chuck.blogspot.com/ Resume: http://garywilliams.org/resume.htm Store: http://www.cafeshops.com/tfsreluctant/ Phone: (607) 775-0408 Permanent email: gwms(a)corninglink.com

using multiple dac's in one shred?
by Gary Williams 27 Jan '05

27 Jan '05

I was thinking about multiple voice chords and I see dac described in the Programming Guide as [ugen] dac * digital/analog converter * abstraction for underlying audio output device so I thought that it could be the target of multiple ugen's in one shred, and tried it here http://garywilliams.org/chuck/bpmulti2.ck It seems to work. So I used it as the basis of an article on http://b-chuck blogspot.com/. But I notice that if I use multiple instances of this chuck bpmulti2.ck bpmulti2.ck it generates interference. Is multiple dac usage legal (and proper)? And does anyone know why multiple instances generate interference? --Gary Williams ---- Chess: http://chessnut.net/ Homepage: http://garywilliams.org/ Blog: http://tfs_reluctant.blogspot.com/ ChucK Blog: http://b-chuck.blogspot.com/ Resume: http://garywilliams.org/resume.htm Store: http://www.cafeshops.com/tfsreluctant/ Phone: (607) 775-0408 Permanent email: gwms(a)corninglink.com

question about types
by Gary Williams 27 Jan '05

27 Jan '05

I've been fiddling with the ModalBar and TubeBell STK functions, and I wrote a subroutine that took a TubeBell. as a parameter: fun int presets( TubeBell bell ) { ... } but accidentally called it with a param that was a ModalBar. This did not gen a type error and I got silence until I added a param that doesn't exist in a TubeBell. Then ChucK complained that it couldn't find TubeBell strikePosition. Howcum? (i.e., why no typing complaint? It took me an hour to find out why I was getting silence...) -- Gary ---- Chess: http://chessnut.net/ Homepage: http://garywilliams.org/ Blog: http://tfs_reluctant.blogspot.com/ ChucK Blog: http://b-chuck.blogspot.com/ Resume: http://garywilliams.org/resume.htm Store: http://www.cafeshops.com/tfsreluctant/ Phone: (607) 775-0408 Permanent email: gwms(a)corninglink.com

a plea for an exit() verb, and an include mechanism
by Gary Williams 23 Jan '05

23 Jan '05

As I noted on the features request page on the wiki, I think we need an exit() function. I noticed in my scalefunction.ck example on b-chuck, it would have been good to issue an error message and exit in the bad-parameter value case -- but I don't see exit() in the programmers guide. Also, and include verb to allow inclusion of function modules and header files would be helpful. (Similar to the #include in C...) --Gary ---- Chess: http://chessnut.net/ Homepage: http://garywilliams.org/ Blog: http://tfs_reluctant.blogspot.com/ ChucK Blog: http://b-chuck.blogspot.com/ Resume: http://garywilliams.org/resume.htm Store: http://www.cafeshops.com/tfsreluctant/ Phone: (607) 775-0408 Permanent email: gwms(a)corninglink.com

A new ChucK blog -- Beginning ChucK -- and an excercise on the A scale
by Gary Williams 21 Jan '05

21 Jan '05

I know as a programmer and former tech writer that I often learn more when I try to write about it, so I decided that in learning ChucK I would write about learning it. So today I started a blog, <a href=http://b-chuck blogspot.com/ target=bchuck>Beginning ChucK -- http://b-chuck.blogspot com/</a>. The first real piece I did is an exercise in writing scales -- in this case a simple A scale exercise. Please let me know what you think. I'd appreciate any suggestions. --Gary ---- Chess: http://chessnut.net/ Homepage: http://garywilliams.org/ Blog: http://tfs_reluctant.blogspot.com/ ChucK Blog: http://b-chuck.blogspot.com/ Resume: http://garywilliams.org/resume.htm Store: http://www.cafeshops.com/tfsreluctant/ Phone: (607) 775-0408 Permanent email: gwms(a)corninglink.com

Serial or USB access?
by Lance Boyle 19 Jan '05

19 Jan '05

Hi. First post to this list. Following up on mention of ChucK a few days ago on music-dsp. Using ChuckK, how would one access a headtracker or mouse from either a serial port (via Keyspan serial-USB adapter) or USB using OS X? Jerry

anyone got tips for using ChucK on Windows XP?
by Gary Williams 17 Jan '05

17 Jan '05

The ChucK materials I've found at Princeton all seem to be aimed at command-line Unix style interfaces. Are there any instructions or tips for using Windows? I've got the .chk files tagged to call ChucK, but that doesn t allow multiple file calls. --Gary ---- Chess: http://chessnut.net/ Homepage: http://garywilliams.org/ Blog: http://tfs_reluctant.blogspot.com/ Resume: http://garywilliams.org/resume.htm Store: http://www.cafeshops.com/tfsreluctant/ Phone: (607) 775-0408 Permanent email: gwms(a)corninglink.com
