by Gabriel G 02 Aug '08

02 Aug '08

Hello Im attempting to write a text to midi program in chuck I have read all the documentation on keyboard options and converting the letters into integers by pressing a key but i want to take say a array of letters and have it convert it but i want to feed a predefined group of letters to be example [abcdefghi] @=> letters letters.getchar() => the letters then be converted to midi I have done something simular to this in Ruby thanks for any help Gabriel G gabrielg1976(a)gmail.com

by Ge Wang 24 Jul '08

24 Jul '08

Dear all, chuck-1.2.1.2 (dracula) is available: http://chuck.cs.princeton.edu/ This release introduces dynamic auto-growing arrays, various fixes, enhancements, and likely new and better bugs/features (see below for a full list). Rebecca and I have added additional UAnae (unit analyzers, see http://chuck.cs.princeton.edu/uana/) in preparation for an all-new upcoming toolkit (following in the footsteps of S.M.E.L.T., see http://smelt.cs.princeton.edu/), which Rebecca will announce soon! A new miniAudicle is on the way from Spencer, as well as an updated audicle version. As always, let us know if you encounter unexpected fishiness (and expected fishiness as well). Many many thanks to Kassen, Kijjaz, Eduard, folks on the electro-music chuck forum, chuck-users, PLOrk, SLOrk, students and staff at CCRMA and Princeton, Fernando Lopez-Lezcano, Carr Wilkerson, and rest of the chuck community for helping to make this release happen!! Thanks and Happy ChucKing, UpChucKing! Best, chuck team CHANGES --- 1.2.1.2 - (added) dynamic, resizable arrays .size( int ) resizes array; .size() returns current size() << operator appends new elements into array .popBack() pops the last element of the array, reducing size by 1 .clear() zero's out elements of the array (see examples/array/ array_dyanmic.ck array_resize.ck) - (added) new UAna: FeatureCollector turns UAna input into a single feature vector, upon .upchuck() new UAna: Flip turns audio samples into frames in the UAna domain new UAna: pilF turns UAna frames into audio samples, via overlap add new UAna: AutoCorr computes the autocorrelation of UAna input new UAna: XCorr computes the cross correlation of the first two UAna input - (added) UGen.isConnectedTo( Ugen ) // is connected to another ugen? - (added) UAna.isUpConnectedTo( UAna ) // is connected to another uana via =^? - (added) int Shred.done() // is the shred done? int Shred.running() // is the shred running? - (added) int Math.ensurePow2( int ) - (added) Math.INFINITY, Math.FLOAT_MAX, Math.FLOAT_MIN_MAG, Math.INT_MAX - (added) TriOsc.width(), PulseOsc.width(), SawOsc.width(), SqrOsc.width() - (added) Std.system(string) is now disabled by default, to enable: specify the --caution-to-the-wind command line flag, for example: %> chuck --caution-to-the-wind --loop - (removed) SqrOsc.width( float ), width is always .5 - (fixed) it's now (again) possible to multiply connect two UGen's - (fixed) OS X only: sudden-motion-sensor HID no longer introduces audio dropouts below peak CPU usage due to added centralized polling; added static Hid.globalPollRate( dur ) to control the central SMS polling's rate - (fixed) Windows only: implementation of array via STL vector::reserve() has been replaced with a more compatible approach (see chuck_oo.cpp) - (fixed) dac amplitude no longer halved!

23 Aug '07

Dear all, chuck-1.2.1.0 (dracula) is available: http://chuck.cs.princeton.edu/ In this new major release of ChucK, we (Rebecca Fiebrink and I) have created a new part of the language devoted to real-time audio analysis, and also combining that with synthesis. In doing so, we are introducing the concept of a "Unit Analyzer" and new chuckian operator. This initial version includes the basic infrastructure and a few "unit analyzers" to get things started. Much more is on the way... To find out more about analysis and ChucK, check out: http://chuck.cs.princeton.edu/uana/ We are presenting this at the ICMC in Copenhagen next week, discussed in this paper: http://soundlab.cs.princeton.edu/publications/uana_icmc2007.pdf A new miniAudicle is on the way, as well as an updated audicle version. Additional goodies include feature/bug enhancements, better bugs and more (see below for complete list). As always, let us know if you encounter unexpected fishiness.

22 Mar '07

Hello, miniAudicle-0.1.3.7 (alpha) is now available. http://audicle.cs.princeton.edu/mini/ This release fixes an occasionally fatal bug on Linux and also includes general performance updates. This release is also integrated with chuck-1.2.0.8, including command line argument support within miniAudicle. Additionally, a Preferences window has been added to Windows and Linux versions to easily allow dynamic reconfiguration of the virtual machine and editor. For Linux users, miniAudicle now supports wxWidgets-2.8, with the caveat that GTK+ 2.10 is also required (due to a bug in miniAudicle) (compiling miniAudicle with wxWidgets-2.6 still works with any GTK+ 2). Special thanks to Imre Kéri, Atte Andre Jensen, Kassen, and Larry Simon for their bug requests, feature reports, and other help with this release. Please let us know about any problems, bugs, feature requests, etc. thanks, miniAudicle team --- 0.1.3.7 - (added)(all) chuck-1.2.0.8 - (added)(all) command line argument support - (added)(Windows,Linux) graphical preferences interface - (added)(Windows,Linux) limited wxWidgets 2.8 support - (added)(Linux) ChucK/miniAudicle logo now associated with application windows - (added)(Mac) smart indentation (including enable/disable Prefs option) (not so smart sometimes) - (added)(Mac) buffer size Preferences option - (added)(Mac) Text, Gauge UI elements - (added)(Mac) enable/disable line numbers Preferences option - (fixed)(Linux) crash closing document windows - (fixed)(Mac) line numbers now scroll dynamically and continue to bottom of document view - (fixed)(Mac) VM and console monitors update when mouse is held down - (fixed)(Mac) improved console monitor performance

by Ge Wang 22 Mar '07

22 Mar '07

Dear all, chuck-1.2.0.8 (dracula) is available: http://chuck.cs.princeton.edu/ Many goodies, feature/bug enhancements, better bugs and more! A major HID backend update by Spencer (plus OS X enhancements: access to sudden motion sensor, hot plugging, etc.), "Dynamics": a Companimuckergate (compressor / expander / limiter / ducker / gate) finally makes it in (thanks to Matt Hoffman and Graham Coleman!!). Masterman Dan Trueman brings his totally wild live/granular sampling UGen to ChucK via the "LiSa" UGen, and ports the classic GenX family from RTcmix. Much bug fixins. Oh, one can finally concatenate strings (warning: this may introduce small memory leaks in the process until garbage collection is finished - so use with care and hopefully outside of tight inner loops). Massive: Spencer has gone through and updated the majority of the documentation (manual and online) and additions will continue to be made!

summer workshop: composing + coding for laptop ensemble
by Ge Wang 08 Feb '07

08 Feb '07

Greetings! This will be a blast => see below. Hope to see you there! Please spam this to others that might be interested. Best, Ge! P.S. chuck-1.2.0.8 is on its way with many fun and destructive new toys... ----- Stanford | CCRMA Summer Workshop: Composing and Coding for Laptop Ensemble (CCL) 2 weeks July 23 - August 3, 2007 Dan Trueman and Ge Wang, with Perry Cook Emphasizing hands-on approaches, this workshop will address the challenges of making music in laptop ensembles. At the core of the workshop will be a set of meta-instruments (laptops with 6-channel hemispherical speakers, associated audio gear, sensors, and controllers) from the Princeton Laptop Orchestra (PLOrk, see http://plork.cs.princeton.edu/). Together, we will act as performers, researchers, composers, and software developers, focusing our attention on instrument design, composition, and music making with these instruments. The challenges are many: what kinds of sounds can we create? how can we physically control these sounds? how do we compose with these sounds? There are also social questions with musical and technical ramifications: how do we organize ourselves in this context? with a conductor? via a wireless network? And so on. Morning sessions will focus primarily on instrument design, composition, and coding issues using the languages ChucK and Max/MSP. Experience with these languages, or programming languages in general, is not required but will be beneficial; depending on the makeup of the group, we may at times divide into smaller groups to teach experience-appropriate skills as needed. We will look at how various composers and engineers have addressed the challenges posed by laptop ensembles and brainstorm new approaches. Afternoon sessions will emphasize music-making of already existing pieces and new pieces created by workshop members. Graduates of both the PID and DSP workshops may find this a useful workshop for applying what they have learned. http://ccrma.stanford.edu/workshops/2007/ http://plork.cs.princeton.edu/ http://chuck.cs.princeton.edu/ --- Thanks!!!

18 Sep '06

Dear all, chuck-1.2.0.7 (dracula) is available: http://chuck.cs.princeton.edu/ API deprecations. In the interest of more consistent naming, we have deprecated some object names. By default, when a deprecated name, such as 'sinosc', is encountered, a warning will be issued, such as 'line(1): deprecated: 'sinosc' --> use: 'SinOsc''. The behavior should be otherwise unchanged. We've added a --deprecate flag that allows you to stop, warn, or ignore upon encountering a deprecated item. The default is 'warn'. Thanks to all who discussed on chuck-users and forum and contributed to the many additions and changes in this release. They include Kassen, Brian, Matt, Jukka, Eduard, Atte, David Powers, Graham Coleman and many others. Also thanks to Ananya for much documentation work.
