Howdy, chuck 1.3.2.0 + miniAudicle 1.3.0 have been released: http://chuck.stanford.edu/release/ Our first release in a year is an exciting one. In anticipation of a number of ChucK-based computer music education initiatives (the forthcoming book "Programming for Musicians and Digital Artists" and Coursera course of the same name), we have added a number of conspicuously absent features and libraries, alongside cleaning up a large number of The most significant change is to formally release chuck as an installer package on Mac OS X and Windows platforms. These installer packages include chuck, miniAudicle, related example files, and the standard set of chugins. (Separate installation of these components is possible but discouraged and not necessarily supported.) Linux, for the time being, is still released as separate source distributions. SerialIO will allow ChucK programmers to easily interact with serial-based hardware devices such as Arduino. A number of string processing utilities have been added. Furthermore, the clear.vm command will enable more dynamic on-the-fly development with public classes. In miniAudicle, the underlying application core on Windows/Linux has been completely rewritten in Qt, greatly improving stability and overall experience. A number of other features and improvements have been added. Special thanks to Ajay Kapur, Kassen, Mark Morris, Bruce Lott, Fernando Lopez-Lezcano, and Romain Michon.

miniAudicle doesn't open files supplied as command line arguments

Hi I just installed the lastes mA under linux, but was a bit surprised to find it doesn't open files I supply as arguments on the command line... atte@skagen:~/music/chuck/live_code$ miniAudicle-alsa *.ck [miniAudicle]: attempting to open file '00_live.ck' on remote The folder contains three .ck files and I get three tabs in miniAudicle named as the three files but they are all blank. Am I doing something wrong or is it a bug? Regards -- Atte http://atte.dk http://modlys.dk

The new release 1.3.2.0
by Stefan Blixt 23 Sep '13

This release looks very interesting. I'm intrigued by the Serial stuff, wonder if I can connect to my monome? I ran the installer, and a chuck program appeared under /usr/bin, however I wonder where the examples end up? I can't find serial examples on the ChucK site... downloading the source bundle to see if I can find some examples there. Cheers! /Stefan
