[Fixed] emacs mode indention problem
by Atte André Jensen 19 Aug '06

19 Aug '06

Hi I solved the mystery of why the emacs mode would indent randomly upon loading a file: tabs! If I change this: (setq default-tab-width 4) to (setq default-tab-width 4) (setq-default indent-tabs-mode nil) everything works well (espcially after getting rid of all tabs in all files and re-indenting them)... For completeness I attach the complete emacs mode... -- peace, love & harmony Atte http://www.atte.dk | quartet: http://www.anagrammer.dk http://www.atte.dk/gps | compositions: http://www.atte.dk/compositions

It's very odd that the Audio MIDI settings can be changed like that by various applications (not just ChucK). But yes, if I reset it to 24 bit, the moment I run ChucK it returns to 16. > Also, run --probe, which may tell you more about the available devices: > > > chuck --probe > Will do, thanks. > > Also, when I run MiniAudicle (MacBook, 10.4.7), adding a shred > > containing access to the dac causes MiniAudicle to crash.

ChucK output bit depth, etc. (OS X)
by mrcarp＠comcast.net 14 Aug '06

14 Aug '06

Hi, What is ChucK's default output bit-depth? 16? every time I run it from the command line is resets the bit depth in OS X 10.4.7's Audio MIDI Settings to 16 bits. Is there a way to specify this? Also, when I run MiniAudicle (MacBook, 10.4.7), adding a shred containing access to the dac causes MiniAudicle to crash. I've tried numerous different settings in both the MiniAudicle preferences and in OS X's Audio MIDI settings. Also, generally, can anyone comment on the infuriating susceptibility of the OS X Audio MIDI settings to being overridden, reset, changed, etc., by practically any application? Obviously, I'm new to Mac/OS X, so any insight into how this affects the applications, themselves, would be appreciated, i.e., should I only worry about what the application audio settings/post is telling me? Thanks a lot, in advance... Matt

complex envelopes?
by babiakb＠bellsouth.net 14 Aug '06

14 Aug '06

if i wanted an envelope in chucK with 6 breakpoints, how could i do this? i only see two ugens, both stk, envelope and adsr. could i somehow use an array and loop with multiple linear envelopes pasted together? (i think an array would be best, but could just also redifine values over and over). has anyone a sample code of this? has anyone else run across this problem in modular synthesis? i think more ugens would be great! thanks brian

Hi, list! After a sudden surge of interst in ChucK on the Electro-Music forum and with Ge's blessing we now have a brand new forum for ChucK and related matters like the Audicles; http://electro-music.com/forum/index.php?f=140 This is not meant as a substitute for the list but as a diferent format for discussion for those who prefer a forum over a list. It might (should?) also lead to more interest in our little language so feel free to chuck it out and maybe spork a account if you'd like. Take care, Kas.

towards sucking less in 64-bit
by Ge Wang 10 Aug '06

10 Aug '06

Hi! We want to, once again, look into getting chuck working correctly in true 64-bit. To that end, if you have a 64-bit machine that chuck crashes (more than usual) on, please consider compiling the attached program, which prints the native data type sizes for your system, and email/post the output. This will give us a rough idea of the various size discrepancies that are most likely causing things to crash horribly under native 64-bit. To compile: g++ -o platform platform.cpp To run: ./platform You should see something like: char: 1 short: 2 int: 4 long: 8 float: 4 double: 8 void *: 8 endian: small Copy and paste the output and send it back with the names of your cpu and operating system. Thank you very much! Best, Ge!

Pause the OSC receiver?
by Ollie Glass 09 Aug '06

09 Aug '06

Is it possible to pause the OSC receiver, ie. stop it listening for events for a while? I'd like to do something like this... //create our OSC receiver OscRecv orec; 6449 => orec.port; // start listening (launch thread) orec.listen(); // some more code ... // pause listener orec.pause(); // more code ... // resume listening orec.listen(); Ollie

syncing to jack
by Atte André Jensen 09 Aug '06

09 Aug '06

Hi I'd like to synchronize some chuck stuff to jack. I generate my own events that all chuck stuff runs from, so I need some way of grabbing jacks time (quite often, unfortunately) and generate the appropriate events. Is this possible, and if so some pointers to get started would be appreciated. Thanks in advance. -- peace, love & harmony Atte

Re: [chuck-users] A modest proposal (caps)
by Jim Hinds 06 Aug '06

To most humans, a Rose is a rose is a ROSE. To computers (who are our servants) these are completely different, and we allow them to push their limitations in our faces. Because, the programmer rightly brings to our attention all the illegal, illegitimate, immoral consequences of our wishes. Not to mention that it is too difficult to implement. And would give rise to a race of moron babies who cant chew their own food. A simple hack to the lexical scanner would be to force the comparison to lowercase for key generators. OR allow a prefix that tells the scanner to force the comparison to lowercasee for the next word. Probably might look like a C cast: (lc)sinOSC. This forces the user to give the scanner a clue to when it is allowed to deviate from its strict string matching rule. The (lc) would be a single lexeme.

more filters
by Kassen 06 Aug '06

06 Aug '06

Hi, again, Can we return to filters again for a moment? I ordered -and read most of- Perry's book (actually I debated some of the trickier bits with a math-whiz friend while sitting on a beach...), I went through the relevant bits in the manual but it's still not clear to me how to go about creating a simple traditional LP filter in chuck. Bandpass and resonators and so on are fairly clear now and a simple averaging lp filter to take the sharp edges of the high end is within my reach as well but the 2 or 4 pole LP filter of traditional/commercial synth designs still elude me. I apreciate the versatility of what we have but I'd still like either some pointers on how to go about creating a sweepable LP filter or perhaps a ready-made Ugen for this. Please? Yours, (if beging ;¬) ), Kas.
