Chugin code signing issue on macOS
by David Braun 04 Jun '21

04 Jun '21

I've had success with a Chugin on Windows but have an issue on macOS. I build the Chugin in terminal: cmake -Bbuild cd build make Then I rename the libWarpBuf.dylib to a WarpBuf.chug and place it in /usr/local/lib/chuck/ This is the console log in miniAudicle when trying to use the chugin. [chuck]:(3:SEVERE): | | | error from chuck_dl: 'dlopen(/usr/local/lib/chuck/WarpBuf.chug, 2): no suitable image found. Did find: /usr/local/lib/chuck/WarpBuf.chug: code signature in (/usr/local/lib/chuck/WarpBuf.chug) not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.' How can I fix this? I also tried cmake -Bbuild -G Xcode and then compiling using the xcode project, with various experiments with provisioning profiles / code signing, but it didn't work. Thank you!

Building MiniAudicle on RaspberryPi 4
by Matt Comeione 20 May '21

20 May '21

I’m attempting to build MiniAudicle on a RaspberryPi 4, however, I am getting the following error in the build process: /usr/bin/ld: cannot find -lqscintilla2 The dependency required for apt based systems is indicated as libqscintilla2-dev, however, on Raspbian the closest library is libqscintilla2-qt4-dev which appears not to be correct. Any suggestions on getting this to build?

New chugin that warps audio like Ableton Live
by David Braun 18 May '21

18 May '21

I created a chugin that warps and transposes audio like Ableton Live does with clips. It actually parses Ableton ".asd" files in a kind of hilariously hacky way. https://github.com/ccrma/chugins/pull/51 Control parameters: - .read - ( string , WRITE only ) - loads file for reading - .playhead - ( float , READ/WRITE ) - set/get playhead position in quarter notes relative to 1.1.1 - .loop - ( int , READ/WRITE ) - toggle looping - .play - ( int , READ/WRITE ) - toggle playing - .bpm - ( float , READ/WRITE ) - set/get BPM rate ( Audio files without Ableton warp files are assumed to be 120 BPM ) - .transpose - ( float , READ/WRITE ) - set/get pitch transpose in semitones - .startMarker ( float , READ/WRITE ) - set/get start marker of the clip - .endMarker ( float , READ/WRITE ) - set/get end marker of the clip - .loopStart ( float , READ/WRITE ) - set/get loop start marker of the clip - .loopEnd ( float , READ/WRITE ) - set/get loop end marker of the clip - .reset ( float , WRITE ) - reset the internal process buffer of the Rubberband stretcher It's working well in my tests on Windows, so please give it a try, especially if you're on macOS which I haven't been able to test. Cheers, David

Hi! I'm trying to build miniAudicle under debian but the build fails like this: /usr/bin/ld: cannot find -lqscintilla2 collect2: error: ld returned 1 exit status make[1]: *** [makefile.qt-alsa:270: miniAudicle] Error 1 make[1]: Leaving directory '/mnt/data/atte/medium/software/chuck/miniAudicle-1.3.5.2/src' make: [makefile:38: linux-alsa] Error 2 (ignored) If I try to install libqscintilla2-dev I get this: atte@pandrup:~/software/chuck/miniAudicle-1.3.5.2/src$ sudo apt-get install libqscintilla2-dev Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'libqscintilla2-qt4-dev' instead of 'libqscintilla2-dev' libqscintilla2-qt4-dev is already the newest version (2.10.4+dfsg-2.1). Any pointers appreciated. -- Atte http://latestyoutube.a773.dk | http://a773.dk

Newbie troubleshooting Mac/Windows
by Tim Burgess 24 Mar '21

24 Mar '21

Hi, I've installed ChucK 1.4.0.1 using the provided installers on both the Mac Catalina and Windows 10 partitions of my BootCamped MacBook Pro. Booted to the Mac side of things, I created and successfully ran the first tutorial program, as far as randomizing the sine wave frequencies, so that's great. I then booted to Windows and used the same file to validate my installation but, unfortunately, I got no audio output and no error messages. Pressing Ctrl+C generates a message saying "cleaning up", but the command prompt never returns. Can anybody help out a newbie with troubleshooting tips, please? Cheers. Tim

hello

Hello chuck users, just joined the list and wanted to say a brief hello, enjoying Chuck. Really liking the clear syntax and the emphasis on multithreading. Actually had a specific question related to a function call in linux, but it managed to answer itself in the course of writing this mail. I'm on a debian buster distro and running chuck from inside a tmux session running in bash (why not make life as difficult as possible?!) Look forward to seeing what's going on in the community and hopefully can contribute in some positive ways.

Re: [chuck-users] [chuck users] Mic on Mini on Mojave+
by David Loberg Code 02 Mar '21

I have students who have encountered this general problem with mics, keyboard, and trackpads (with OSX 10.14/15 and OSX 11) Personally, I have never gotten miniAud to trigger the "wants to access" prompt yet. I use this work-around: Open the application Terminal and type the following: open /Applications/miniAudicle.app/Contents/MacOS/miniAudicle This opens miniAudicle via Terminal which allows it to inherit all of the access permissions of Terminal. The above link is assuming that your miniAudicle is located in the Applications folder on your drive. Otherwise you will need a different directory path.
