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

Wishlist and bugreport from hacking
by Mikael Johansson 09 Dec '04

09 Dec '04

Some things that would be nice to be able to do - now that we've started hacking things with new ulib_foo constructs... * capability to build ulib_foo functions that can treat the dur primitive type. * The handling of parameter input to ulib functions is severely flawed, including lack of type security across platforms and probably not 64-bit secured: the method for retrieving multiple parameters as done in the implementation of math.pow will break down if sizes of ints, floats and pointers start to differ; and should in any case be wrapped in some more robust handling way; for instances those actually present in C++ a priori. * You have several various memory leaks and similar problems; use of valgrind is advised. If these things are not possible due to not being harmonic with the ChucK way of thinking; please tell us what to do instead (instructions for building .ckx would be nice for instance... =) -- Mikael Johansson | To see the world in a grain of sand mikael(a)johanssons.org | And heaven in a wild flower http://www.mikael.johanssons.org | To hold infinity in the palm of your hand | And eternity for an hour

(win32) type checker crash fixed
by Ge Wang 24 Nov '04

24 Nov '04

Dear All, (win32 version only): There was a bug in the type checker where it would crash on calling functions in namespaces like std.rand( 1.0, 2.0 ). (wrong # of arguments and type should be int) The correct behavior is to (not crash, first of all and) return meaningful message that it doesn't fit the prototype. This has been fixed and will be in the next release. In the meantime, there is an updated chuck_type.cpp and win32 executable: http://chuck.cs.princeton.edu/release/snapshots/ This doesn't seem to affect other platforms (we are tracking down why not) Thanks to ./rrm and Mikael for finding this. Best, Ge!

Classic scales and note frequencies
by Mikael Johansson 18 Nov '04

18 Nov '04

Just as a little benefit to everyone out there (and mainly because I myself grew annoyed), I looked up the frequencies for a welltempered scale, hacked out the ChucK commands assigning those frequencies to names I could cope with, looked up a list of MANY canonical scales, hacked that to a format I liked, and produced a small example ChucK script that will play a mandolin tune in any "cultural" melodic context you want. =) By the way. I WANT arrays. This'd be SO much easier with arrays! Enjoy: <<<<<<<< ChucK definitions for "common" note names >>>>>>>> 55.000=>float A0; 110.000=>float A1; 220.000=>float A2; 440.000=>float A3; 880.000=> float A4; 1760.000=>float A5; 58.270 =>float Bb0; 116.541 =>float Bb1; 233.082 =>float Bb2; 466.164 =>float Bb3; 932.328 =>float Bb4; 1864.655=>float Bb5; 61.735 =>float B0; 123.471=> float B1; 246.942=> float B2; 493.883=> float B3; 987.767=> float B4; 1975.533=>float B5; 65.406 =>float C0; 130.813 =>float C1; 261.626 =>float C2; 523.251 =>float C3; 1046.502 =>float C4; 2093.005=>float C5; 69.296 =>float Db0; 138.591 =>float Db1; 277.183 =>float Db2; 554.365 =>float Db3; 1108.731 =>float Db4; 2217.461=> float Db5; 73.416 =>float D0; 146.832 =>float D1; 293.665 =>float D2; 587.330 =>float D3; 1174.659 =>float D4; 2349.318=> float D5; 77.782 =>float Eb0; 155.563 =>float Eb1; 311.127 =>float Eb2; 622.254 =>float Eb3; 1244.508 =>float Eb4; 2489.016=>float Eb5; 82.407 =>float E0; 164.814 =>float E1; 329.628 =>float E2; 659.255 =>float E3; 1318.510 =>float E4; 2637.020=>float E5; 87.307 =>float F0; 174.614 =>float F1; 349.228 =>float F2; 698.456 =>float F3; 1396.913 =>float F4; 2793.826=>float F5; 92.499 =>float Gb0; 184.997 =>float Gb1; 369.994 =>float Gb2; 739.989 =>float Gb3; 1479.978 =>float Gb4; 2959.955=>float Gb5; 97.999 =>float G0; 195.998 =>float G1; 391.995 =>float G2; 783.991 =>float G3; 1567.982 =>float G4; 3135.963=>float G5; 103.826 =>float Ab0; 207.652 =>float Ab1; 415.305 =>float Ab2; 830.609 =>float Ab3; 1661.219 =>float Ab4; 3322.438=>float Ab5; <<<<<<<< >>>>>>>>> <<<<<<<< Commented list of scales >>>>>>> // Scale references // 1 2 3 4 5 6 7 8 9 10 11 12 13 // Chromatic C Db D Eb E F Gb G Ab A Bb B C // Spanish 8 Tone C Db Eb E F Gb Ab Bb C // Flamenco C Db Eb E F G Ab Bb C // Symmetrical C Db Eb E Gb G A Bb C // Diminished C D Eb F Gb Ab A B C // Whole Tone C D E Gb Ab Bb C // Augmented C Eb E G Ab B C // 3 semitone C Eb Gb A C // 4 semitone C E Ab C // // Ultra Locrian C Db Eb E Gb Ab A C // Super Locrian C Db Eb E Gb Ab Bb C (Ravel) // Indian-ish* C Db Eb E G Ab Bb C // Locrian C Db Eb F Gb Ab Bb C // Phrygian C Db Eb F G Ab Bb C // Neapolitan Min C Db Eb F G Ab B C // Javanese C Db Eb F G A Bb C // Neapolitan Maj C Db Eb F G A B C // Todi (Indian) C Db Eb Gb G Ab B C // Persian C Db E F Gb Ab B C // Oriental C Db E F Gb A Bb C // Maj.Phryg.

version 1.1.5.4 released + keywords
by Ge Wang 18 Nov '04

18 Nov '04

Dear All, chuck-1.1.5.4 is another incremental update with bug fixes and one rather questionable new keyword: http://chuck.cs.princeton.edu/ we apologize for the lack of language references. there is now a somewhat definitive list of keywords: http://chuck.cs.princeton.edu/doc/program/keywords.html this is mirrored from the wiki - feel free to post stuff here: http://wiki.cs.princeton.edu/index.php/ChucK_Keywords Please let us know if there are any issues. --- 1.1.5.4 - 2004.11.18 - fixed clicks when using adc unit generator (thanks to paul botelho for testing) - added 'maybe' keyword maybe == 0 or 1, with 50% probability each new examples: - maybe.ck : the maybe keyword - bad idea? maybe. - maybecli.ck : maybe click, maybe not adc examples work better: - adc.ck - echo.ck - i-robot.ck HappY ChucKing!

version 1.1.5.3 released
by Ge Wang 09 Nov '04

09 Nov '04

Dear All, chuck-1.1.5.3 is released. We have resumed full-speed development on the major release. Until that is done, there will be a few more minor releases (such as this one). Source + binaries (for OS X and win32): http://chuck.cs.princeton.edu/ --- 1.1.5.3 - 2004.11.9 - when a shred is removed from VM, all children shreds are also recursively removed (this fix crash due to removing shreds with active children shreds) (to keep children around, put parent in infinite time-loop) (this isn't always good - real solution coming soon) - 'start' keyword now available - holds the a shred's begin time updated examples: - powerup.ck : start local variable changed name - spork.ck : added infinite time loop to keep children active HappY ChucKing!

Scoping and wishlists
by Mikael Johansson 28 Oct '04

28 Oct '04

So, if I define things in one .ck file and then add it to a running loop, all things are local to that file, right? Is there any way of defining very global stuff? So that I could edit and spork completely independently one snippet that plays some loop and another snippet that changes some parameters (for instance having a continuous mandolin hammering away, but changing scales and other parameters that control its tune...) Another thing - I've been on about this before a little... As of now, the biggest restraint I find is that I have NO idea of the finer details of the language. At all. Can I manipulate strings? Can I concatenate strings? Is there any way to give output without getting a newline automagically? What do all the operators that I've seen in the lex/yacc files _DO_? -- Mikael Johansson To see the world in a grain of sand mikael(a)johanssons.org And heaven in a wild flower http://www.mikael.johanssons.org To hold infinity in the palm of your hand http://blog.mikael.johanssons.org And eternity for an hour
