pieces written in ChucK
by Joel Matthys 09 Jun '11

09 Jun '11

I've been teaching ChucK to my Intro to Electronic Music students this quarter at CCM here in Cincinnati, and I've struggled to find recordings of pieces to play in class. I have one: http://soundcloud.com/jwmatthys/shearpin Are there others out there? Is there a reason so few use ChucK for fixed-format? Joel

ChucK and Pulseaudio (Ubuntu 10.04)
by Lucas Zawacki 09 Jun '11

09 Jun '11

Hey guys. I've recently crafted some fun stuff with chuck and I'd like to make a recording of my desktop together with the sound I'm generating. I'm on Ubuntu, using gtk-recordmydesktop for this purpose and everything is fly until I try to capture the audio.... It seems that ChucK is not sending it directly to pulse, so when I try to record from it I get no sound. Notice that other apps, like my music player, do get recorded correctly. I'm using chuck-alsa, but I tried chuck-oss too with no success. I even tried chuck-jack and then things went pretty bad, but I suspect it's recordmydesktop fault. All in all I need some help here... is there a reason why chuck-alsa is not routing through pulse? Thanks in advance.

We perform Clix with CiCLOP, the Cincinnati Composers Laptop Orchestra Project. Most of our DSP is in ChucK.

Resignation and transition
by Adam Tindale 06 Jun '11

06 Jun '11

Hi All, I would like to send my official resignation as a core member of the documentation team. I no longer use ChucK to the extent that I am an expert and I have not committed to the documentation in at least a year. I want to see the community flourish, as I see on the list, and as such I am serving as a gatekeeper to updating and improving the manual. Last year we tried a documentation push that had some interesting developments and I think was ultimately a failure because we did not push enough traffic there. Their export to PDF was ( and in my opinion still is) inadequate for generating a manual that can be shipped with ChucK. My suggestion moving forward is to move to Markdown or asciidoc for generating files that can be easily turned into html or pdf with appropriate style files for each. Github has proved to be an excellent place for collaborating on these types of projects and I would suggest that as a place to get the migrating going. I would be more than happy to help with the migration to a new platform or to help a new person get up to speed on how I generated the PDF manual so they can continue to update it with all of the great discoveries and suggestions on the list. I would also be happy to do some actual porting work of the documentation to a new system that can be more easily maintained if that is what is deemed necessary by the community or new point person. For history, the original manual was generated by me with help from Ge and Phil sometime in 2005 or so. I got into ChucK very seriously at that point and emailed the list or Ge personally to figure out how to do certain things in the language. For every email Ge sent me I created a tutorial or reference and compiled it into a document. Ge, Phil, and I spent many a night generating web references, then I would port that to LaTeX for the PDF manual. Since that time many other people have contributed references that have since been included in the manual and it has grown to the document we know today. It was a lot of fun and I think it had a significant impact on getting new users into ChucK. I want to thank the ChucK team and community, and I look forward to helping you get to the next place. Adam (--art)

Gyration Air Mouse
by Les Hall 06 Jun '11

06 Jun '11

Good day ChucKists! I have finally purchased what looks to be a good motion controller for my particular needs. It is the Gyration Air Mouse Elite. It works great, though my first code attempt at varying a SinOsc produced more zipper than actual sine wave, lol. I know the zipper cannot be avoided in practice, so I'll work on ways to minimize it and /or make use of it. Now, to my question: How do I access all of the axes? This device has a 2-axis gyro and a 3-axis accelerometer, which IMHO packs a powerful punch missing only the roll gyro. I can do all sorts of stuff with it, but I need to get at that axis data. I'm sure it's very simple, how do i do it? Les

Instrument Pickups for Ajay and Others
by Les Hall 04 Jun '11

04 Jun '11

This post is somewhat off-topic to ChucK itself, so please skip it if that bothers you, thanks. All this celebration of Ajay Kapur and the amazing work that he and his students are doing reminded me of a sort of reinvention that my Swedish friend Are and I created together some time ago. It's a type of stringed instrument pickup that has unique properties making it very suitable for creating one's own stringed instruments. I know that part of the ChucK world involves creating unique instruments including stringed ones, so I thought I'd post here. I say reinvented because after we created it, we found prior art in the patent record going back to the 1930's if I recall correctly, and we never did patent out little twist on the theme that made it practical today, so it's yours to use freely. It works by putting neodymium magnets under the strings and then amplifying the tiny currents created in the strings themselves as they vibrate in the magnetic field. Since there are no coils of wire, there is no second-order filter to distort all those beautiful harmonics, and the sound is more "clean" or harp-like than a conventional wound pickup. There are quirks to these pickups, but they are minor to most listeners. You can read all about this new-old pickup system here: http://echuck.othomann.de/eChucK/Guitar_Kit.html Oh, and we did ask for a small contribution from anyone who used it, but not only is that a voluntary gesture, for educational purposes we can waive it altogether. If someone uses the pickup system and tells us about it, that will be plenty reward enough. Please feel free to forward this message or the web link to any related list or person or whatever. Thanks, Les

An Eastern-flavored Happy Birthday to Ajay Kapur in ChucK
by Perry Cook 04 Jun '11

04 Jun '11

Hi all, Ajay is one of the only of us who actively uses ChucK everyday to drive robots!! It's amazingly fun to hook up to his critters via OSC and get them banging away. For that, and many of the other awesome things he does and does for us, I offer this: http://www.cs.princeton.edu/~prc/HBDAjay2011 The code is butt-ugy, inline, copy-paste. That's how I compose short one-off ChucK things. No comments, just music :-) Enjoy!!! PRC

exponential envelope

Is there a generally-accepted method for creating exponential envelopes? It can be managed with Gen5, but the result is somewhat clumsy and requires a very fast loop. -Alex
