mailing list problem

I have noticed that sending a reply on this mailing list doesn't work as usual. It seems that by default the reply message is not sent to the list but to the original poster. Can somebody else confirm this problem? -mb

Works perfectly. Just found a minor issue related to OSC. When receiving an OSC event containing a string parameter (eg. "abc") I get an additional message add string |abc| ( 4 ) Looks like some debugging code... -mb

Makes sense. However, removing the program doesn't seem to work for me. When using %chuck - program.ck I get the message [chuck](VM): cannot remove: no shred with id 0... -mb

OSC receiver

Hi, congratulations on the new release! I'm on OS X and in particular interested to use MIDI and OSC events. So far MIDI in/out seems to work fine here. OSC send works too, but with the example 'opensound_demo_recv.ck' I get an error message: class 'OSC_Recv' has no member 'event'. -mb

[solution] compile and link problem under FC3...
by Furlan Primus 28 Aug '05

28 Aug '05

Hi, Earlier today I had trouble compiling and linking the 'Dracula' version of ChucK. After some emails to Ge Wang a solution was found. The problem was that when compiling for linux-alsa it was looking for a file called sndfile.h and that file was NOT on my system as I have a precompiled version of libsndfile. The solution was to follow the directions in the makefile.alsa file: #----------------------------------------------------------------------------- # by default, ChucK on linux needs libsndfile... # comment the next 3 lines to use a pre-configured libsndfile #----------------------------------------------------------------------------- # FLAGS+= -D__CK_SNDFILE_NATIVE__ # LIBS+= -lsndfile # SF_OBJ= Once that was commented out (as above) the compilation & linking went without any further delay. Maybe this will assist someone else who experiences a similar problem. ciao, furlan -- Home: http://flprim.us/index.html Ambition is a poor excuse for not having sense enough to be lazy. -- Milan Kundera

Congratulations on the release! I look forward to learning all the new stuff you've made. A quick question that I need to answer for a potential Chuck project: is there a Chuck function that returns today's date in some form? I remember a built-in function in C that did this–is there a Chuck equivalent? Again, excellent work and congrats on the release. As soon as the Audicle gets set, I can sit out front with a projector and amaze unwitting passersby. --Jeff On Aug 25, 2005, at 9:00 AM, chuck-request(a)lists.cs.princeton.edu wrote: > Send chuck mailing list submissions to > chuck(a)lists.cs.princeton.edu > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.cs.princeton.edu/mailman/listinfo/chuck > or, via email, send a message with subject or body 'help' to > chuck-request(a)lists.cs.princeton.edu > > You can reach the person managing the list at > chuck-owner(a)lists.cs.princeton.edu > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of chuck digest..." > Today's Topics: > > 1. version 1.2.0.0 (dracula) released (Ge Wang) > 2. spork ~ chuck-users ( new mailing_list + more ) (Ge Wang) > > From: Ge Wang <gewang(a)CS.Princeton.EDU> > Date: August 25, 2005 6:07:57 AM PDT > To: ChucK Audio Programming Language Mailing List > <chuck(a)lists.cs.princeton.edu> > Subject: [chuck] version 1.2.0.0 (dracula) released > > > Dear All, > > chuck-1.2.0.0 is released.

load_dll from chuck code?
by Robin Davies 28 Aug '05

28 Aug '05

I'm very excited to see Chuck 1.2.2.0, and I'm eager to start tweaking. I'd particularly like to get started on writing external C++ UGens for Chuck. I own source for some particularly useful functions that I'd love to get tied into Chuck (intention to donate as an external project), but I can't seem to find the procedure for loading an external dll either from Chuck code, or from the command-line, or otherwise. All the code seems to be there to load an external DLL, but it doesn't seem to be hooked up to anything yet. Am I missing something? Are there any immediate plans to expose this, or should I get busy hacking away? UGens that I'm interested in implementing: - hosting VST plugins in chuck (a huge priority for me, have source code, will integrate, if nobody else is doing this) - maybe Chuck as a VST plugin (not a huge priority for me) - Some more basic instrument building blocks for ugens, band-limited waveforms, particulary. - High-quality sample interpolators. Is anyone else out there doing 3rd-party development for Chuck yet? I'd be interested in sharing plans and priorities. Regards, Robin Davies

OSC utilies/programs for Win32?
by Robin Davies 26 Aug '05

26 Aug '05

Does anyone know of a source of OpenSoundControl utilities for Win32? Something to test-drive chuck's support for OSC would be great. Something to do basic sequencing would be greater. Something to drive chuck from buildable GUI would be greater still. Regards, Robin Davies
