syntax coloring for chuck in jedit
by jes�s gollonet 23 Aug '06

23 Aug '06

Hi all. I've just published a chuck edit mode (an xml file defining a syntax coloring scheme) for the jedit code editor. It gives different colors for ugens, methods, keywords and operators. If anyone uses jedit, you can grab the xml file and see the instructions in my blog: http://www.jesusgollonet.com/blog/?p=135 If you want to give it a try, i totally recommend it as a single all-purpose editor. It's totally extensible and I'm working on some more niceties for chuck editing (abbreviations, macros...). www.jedit.org Best! -- jesús gollonet htt://www.jesusgollonet.com

stk ugens
by Bradford Garton 19 Aug '06

chUcK-people -- Maybe I'm unaware of something (I'm fairly new to chuck-ing), but I try a really simple script like this: Saxofony sax; 0.5 => sax.stiffness; and I get this: [ccc.ck]:line(3): class 'Saxofony' has no member 'stiffness' ditto for a number of the other control parameters listed in the docs. Grepping through the code shows that they don't seem to exist. Or am I missing something fundamental? brad http://music.columbia.edu/~brad

[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).

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!

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

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.

If you're thinking of dropping the lowercase names in the future perhaps you could allow them but print a deprecated warning when they're used. Ollie

A modest proposal (caps).
by Kassen 05 Aug '06

05 Aug '06

Ok, list... I realise this may be edging on dangerous teritory but I was just fooling around with the miniaudicle and some filters and had to type this; sawosc s => TwoPole f => dac; This works perfectly; that's not the problem. My problem is that it's "TwoPole" and not "Twopole" or "twopole" and yet it's not SawOsc but sawosc. I realise this is because we are borowing from the STK and also using new stuff but.... Well, to be honest I'd realy prefer a consistent use of caps. Frankly I'd be in favour of simply making it all lowercase or at least a consistent use of case because this -to me- is hard to remember. Yours, Kas.

arrays holding arrays?
by Kassen 04 Aug '06

04 Aug '06

Hi list, I have a slight issue. I'd like to have a array in which every object itself is a array. Particularly I'd like to have one of 8 locations each of which holds a array of length 32. I tried this; int[32] memory[8]; And the miniaudicle immediately complains. I know the manual doesn't explicidly say arrays can hold arrays but it didn't explicidly say functions can return arrays either so I thought I'd try anyway (and frankly I feel this should simply be possible). Theoretically speaking I could get by with a 2d array but I'd realy like to be able to go; if(some event dealing with storing patern memories) { patern @=> memory[4]; } if(some event dealing with recaling patern memories) { memory[3] @=> patern; } How to go about this? In the interest of staying readable and compact I'd much prefer no to have to loop over a 2d arrays row in order to copie values one by one. Should I use the asociative array features? Am I missing some syntax bit? Are there reasons not to store arrays in arrays? Yours, Kas.

note names
by Bruce Murphy 03 Aug '06

03 Aug '06

There's a convention for naming notes like C4 or Eb3 or A#-1 that seems quite commonly used in music applications. I would very much like a note nme to MIDI note number converter to make certain things I do with ChucK a lot more readable and easy to change - m.noteon(snd.stom("C#4")); for example. The problem is that middle-C (MIDI note 60) is not well defined. Quite a few sources suggest it should be C4 a smaller number suggest C3. Once a function to do the conversion is in ChucK, it would be difficult to change without irritating people who use it. Does anyone have a stronger opinion than I as to what the middle-C note name should be? B> -- Packrat (BSc/BE;COSO;Wombat Implementor) Nihil illegitemi carbovndvm

updated MIDIsender wrapper class
by Bruce Murphy 31 Jul '06

31 Jul '06

I've been playing with the midiwrapper class I sent in yesterday and I'm convinced that it's getting to the useful stage. At least I was able to get ChucK noodling away on several modules while I worked :) With great embarassment I also finally noticed that string comparisons are already there so I can implement this: MIDIsender m; m.open("JD990"); Only works on Mac OS X for the moment, becuase we've got AudioMIDI setup to keep track of where things are plugged in. The interface is there for other platforms if you can identify ports somehow. The latest code for the class, fledgling documentation on how to use it and several examples showing useful functionality are at: http://www.rattus.net/~packrat/audio/ChucK/ I have several other things I want to do, but some of them are waiting on better string handling. A written note (C#3) to midinote converter is pretty high on that list. It might be easier to put into the std library, or should there be a MIDI library?

MIDI sending, small messages
by Bruce Murphy 31 Jul '06

31 Jul '06

I haven't been able to figure this out either from the documentation or the code (although I must admit that I'm still a little fuzzy on how the underlying functions get exported with typing to ChucK programs) How do I send short (2 byte) MIDI messages? I know that in theory spurious bytes won't matter, but since I use older MIDI kit, I don't want to take the chance of confusing it. If I'm missing documentation on how this works, I'd love to hear about it so I can just pull what I need out of the code :) (Or even documentation on the how Chuck VM -> underlying implementation code works) B> -- Packrat (BSc/BE;COSO;Wombat Implementor) Nihil illegitemi carbovndvm

chuck MIDI handling
by Bruce Murphy 30 Jul '06

30 Jul '06

Just a question, before I run off and duplicate anything. I use a lot of outboard MIDI stuff and am very interested in using chuck for glue and MIDI generation. As far as I can see, MIDI handling in chuck is fairly clumsy, particularly for MIDI generation. Is anyone currently working on developing a more friendly interface for this or is it worth taking some time over. Also, is the general push for this sort of thing to be put in core ChucK or to sit off to one side? B> -- Packrat (BSc/BE;COSO;Wombat Implementor) Nihil illegitemi carbovndvm
