Chunity (ChucK for Unity): Release!
by Jack Atherton 29 Jul '22

29 Jul '22

Dear all, Hello! I'm happy to announce the initial official release of Chunity (ChucK for Unity)! http://chuck.stanford.edu/chunity/ http://u3d.as/1bvM Chunity is the integration of ChucK in Unity. (For those of you not familiar with the Unity game engine, Chunity gives you the ability to do realtime sound + music generation natively in Unity, tightly coupled to interactions with graphical objects.) You can use most (possibly all?) ChucK features, run new ChucK code on-the-fly at any time, and communicate between Unity and ChucK using "global" (new keyword!) ints, floats, strings, Events, and 1D int and float arrays. (More types to come!) You can even run multiple VMs that share the same strong timing! Check out this video of things people have already made with Chunity: https://vimeo.com/263613454 And check out the original description of Chunity in this NIME paper: http://chuck.stanford.edu/chunity/files/2018-nime-chunity.pdf We want to know what you all do with this! Please feel free to send works in progress, bug reports, feature requests, finished works, etc. to the chuck-users mailing list! We are also planning to send a sparse series of follow-up emails covering tutorials, new features, and cool projects that people in the community have created. Please see the tutorials, documentation, etc. at the official Chunity website: http://chuck.stanford.edu/chunity/ Thank you and happy ChucKing!! Best, Jack + the ChucK team Music:Computing:Design @ CCRMA

style manual for coding? (Possibly off topic)
by Charlie 31 Mar '19

31 Mar '19

hey all, sorry if this is off topic but I'm starting to realize that my haphazard coding style is becoming a problem, as I build a live coding practice based in ChucK. I'm wondering if there is a "Strunk and White" for coding covering stuff like indentation, naming conventions, when to use a function or class for something, etc etc. My formal training in coding is limited to a FORTRAN class that I took in the 1980s at the Department of Agriculture but I've done some stuff in C, so a book oriented around C or C++ would probably work. Thanks in advance! Charlie

issue adding elements to an array
by Mario Buoninfante 28 Mar '19

28 Mar '19

Sorry, this is the right code that shows 'the issue': function static void insert_1( string array[], string x, int pos ) { string mom_arr[0]; if( pos < array.size() && pos >= 0 ) { for( pos => int c; c < array.size(); c++ ) { mom_arr << array[c]; } x => array[ pos ]; array.size( array.size() + 1 ); for( 0 => int c; c < mom_arr.size(); c++ ) { mom_arr[c] => array[ c + pos + 1 ]; } } else if( pos == array.size() ) { array << x; } } function static void insert_2( string array[], string x, int pos ) { string mom_arr[0]; if( pos < array.size() && pos >= 0 ) { for( pos => int c; c < array.size(); c++ ) { mom_arr.size( mom_arr.size() + 1 ); array[c] => mom_arr[ c - pos ]; } x => array[ pos ]; array.size( array.size() + 1 ); for( 0 => int c; c < mom_arr.size(); c++ ) { mom_arr[c] => array[ c + pos + 1 ]; } } else if( pos == array.size() ) { array << x; } } ["a", "b", "c"] @=> string s_1[]; insert_1( s_1, "ONE", 1 ); for( 0 => int c; c < s_1.size(); c++ ) { <<< s_1[c] >>>; } <<< "" >>>; ["a", "b", "c"] @=> string s_2[]; insert_2( s_2, "ONE", 1 ); for( 0 => int c; c < s_2.size(); c++ ) { <<< s_2[c] >>>; }

issue adding elements to an array
by Mario Buoninfante 28 Mar '19

28 Mar '19

Hi, I suspect I'm probably doing something stupid and just not realizing it, but I don't understand why these 2 functions ("insert_1" and "insert_2") are giving me 2 different results: function static void insert_1( string array[], string x, int pos ) { string mom_arr[0]; if( pos < array.size() - 1 && pos >= 0 ) { for( pos => int c; c < array.size(); c++ ) { mom_arr << array[c]; } x => array[ pos ]; array.size( array.size() + 1 ); for( 0 => int c; c < mom_arr.size(); c++ ) { mom_arr[c] => array[ c + pos + 1 ]; } } else if( pos == array.size() ) { array << x; } } function static void insert_2( string array[], string x, int pos ) { string mom_arr[0]; if( pos < ( array.size() ) && pos >= 0 ) { for( pos => int c; c < array.size(); c++ ) { mom_arr.size( mom_arr.size() + 1 ); array[c] => mom_arr[ c - pos ]; } x => array[ pos ]; array.size( array.size() + 1 ); for( 0 => int c; c < mom_arr.size(); c++ ) { mom_arr[c] => array[ c + pos + 1 ]; } } else if( pos == array.size() ) { array << x; } } ["a", "b", "c"] @=> string s_1[]; insert_1( s_1, "ONE", 1 ); for( 0 => int c; c < s_1.size(); c++ ) { <<< s_1[c] >>>; } <<< "" >>>; ["a", "b", "c"] @=> string s_2[]; insert_2( s_2, "ONE", 1 ); for( 0 => int c; c < s_2.size(); c++ ) { <<< s_2[c] >>>; } It seems like expanding an array with '<<' instead of using .size(int n) is giving me some problem. I'm on MacOS Sierra 10.12.6 Cheers, Mario

Hi, Do we have anything like an 'eval' function in ChucK? Cheers, Mario

Hi, I'm happy to look into it in the next days.

Hi, I just noticed that the ChucK Ubuntu package is quite old (v 1.2). Would it be possible to update it? What's the procedure for that? Cheers, Mario

FaucK - issue with 'v' methods
by Mario Buoninfante 19 Mar '19

19 Mar '19

Hi, I'm using the FaucK chugin and I don't know why when I use the 'compile' method to load a Faust script, then I cannot change the parameter in it (ie my_faust.v("param", value) ). The same script, when 'embedded' in the ChucK code using 'eval', works fine. I also tried specifying the entire path of the parameter, but doesn't seem to work (ie "Folder/MyFaust/param"). Does anyone have the same issue? I tried on MacOS Sierra. Cheers, Mario

Re: [chuck-users] Convolution Reverb (Posed by: Julien Saint-Martin)
by Perry Cook 03 Mar '19

If the impulse response is short enough, or real-time isn’t important, then the FIR chugin can be used. FFT-based convolution is possible using the FFT/iFFT UANAs, but latency and real-time are issues. To deal with that, It would be possible to factor into a nice systolic topology using shorter FFTs and delay lines to line everything up. I don’t know of a specific chugin or example other than those. Someone should write one :-)) Prc Sent from my iPhone > On Mar 1, 2019, at 9:00 AM, chuck-users-request(a)lists.cs.princeton.edu wrote: > > Send chuck-users mailing list submissions to > chuck-users(a)lists.cs.princeton.edu > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.cs.princeton.edu/mailman/listinfo/chuck-users > or, via email, send a message with subject or body 'help' to > chuck-users-request(a)lists.cs.princeton.edu > > You can reach the person managing the list at > chuck-users-owner(a)lists.cs.princeton.edu > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of chuck-users digest..." > > > Today's Topics: > > 1.
