I thought it was trivial until I realized that there may be multiple loops with multiple minimum block sizes. However, it may be trivially doable after a little non-trivial thinking. I was going to ask whether circular chucks was a feature you were particularly attached to, when I saw somebody posting about the fun they were having with delays and echos. And then, in a blinding flash of insight, I understood why the Stk Echo doesn't have a feeback property. (echo echo echo echo). <... thinking hat back on> - Robin Davies.

Block execution of ugens?
by Robin Davies 02 Sep '05

02 Sep '05

ok.. I've been happily hacking away at Chuck 1.2.0.0 sources, with good results so far. I have a set of band-limited oscillaters: currently, bltsawosc, bltsqrosc, and blitosc (impulse train), based on "Alias-Free Digital Synthesis of Classic Analog WaveForms", Stilson/Smith. Also, buzzosc -- a band-limited DSF, similar to SAOL and CSound buzz. All are ready and waiting for access to the load function. I'll probably drop in a bltrectosc (with a width control), soon, as well. (You can have them now, if you like -- a .cpp and .h file, with a query function to register the ugens, all in the same style as current ugens; but I'd like to do a little more testing if you do want it now). Next on the slab: VSTs. And there, things didn't go so well. The key issue is the VSTs like to operate on blocks of audio data rather than running sample at a time. This isn't a huge problem with VST instruments: fetching data in small blocks (say 30 or 40 samples at a time) introduces a small (< 1ms) disconnect between controls and generated audio. But buffering input and output of effects probably isn't going to work as well. I'm really not confident that delaying audio effect output isn't going to produce odd side-effects. I supposed it is possible to try running VSTs one sample at a time. I may give this a try, anyway, in the meantime. But, having written a few VSTs, I don't think I'd be happy if somebody called my VSTs one sample at a time. This probably isn't a priority for you guys right now, but I'd like to raise the idea anyway. What do you think about converting Chuck_VM::run( ) to execute Ugens on blocks of samples at a time? As far as I can see, it's do-able. And the across-the-board performance gains would probably be worth the effort. Roughly, I think the revised code would look like this: #define MAX_UGEN_BLOCKSIZE 32 // or so while( m_running ) run shreds for 1 tick broadcast queued events determine how many ticks we can run ugens for: int ugenBlockSize; if (shreds active) { ugenblocksize = 1; } else { ugenblocksize = min(MAX_UGEN_BLOCKSIZE,ticks_to_next_shred()) } Run_ugens(ugenblocksize); process messages } Ugens would be modified to have input and output buffers of SAMPLE[MAX_UGEN_BLOCKSIZE). Existing UGens would inherit a method that converts Ugen block ticks into single-cycle ticks. The only breaking change I can see is Ugens that are chucked into loops, which is, I think, legal in the current implementation, but would work with buffered input. I seem to remember seeing a mention of this somewhere in the docs. I imagine this might significantly complicate the implementation of ugens written in chuck, too. I'm not sure that I have any decent theories as to how that one would be tackled. (Separate schreduling queues for UGEN tick methods, maybe?) I'm willing to take a crack at an experimental version some time, but I don't imagine your sources are too stable right now. I'd be a bit concerned about making this kind of wide-ranging change on a very active source tree, with no prospect of ever being able to merge it back into mainline sources. Thoughts?

Threading problems w/ win98
by Robin Davies 28 Aug '05

28 Aug '05

The following patch corrects a defect that prevents chuck from receiving TCP commands on Windows 98. chuck_main.cpp 505c505,511 < g_tid = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)otf_cb, NULL, 0, 0); --- > // [rd] pThreadID parameter is not optional on lesser win9x. > DWORD dwThreadID; > g_tid = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)otf_cb, NULL, 0, &dwThreadID); > if (g_tid == NULL) > { > fprintf( stderr, "[chuck]: cannot spawn tcp listener thread\n"); > }

Patches: compiler warnings and test programs
by Rasmus Kaj 14 Jul '05

14 Jul '05

Hi! I've gone and got myself an amd64, and now chuck v2 doesn't seem to be 64-bit clean ... Here's a small first step in an attempt to fix that: First, a tiny patch to allow for the new output from <<<foo>>> in the test programs (which now include the type of foo). Or should the old output be restored instead? Then, a larger patch to fix miscellaneous compiler warnings (mainly printf format strings and order of member initialisers). I've yet ignored warnings about unused variables ... -- Rasmus Kaj --+-- rasmus(a)kaj.se --+-- http://www.stacken.kth.se/~kaj/ To understand recursion, we must first understand recursion

1.2 aproaching? and building on FreeBSD
by Rasmus Kaj 22 Apr '05

22 Apr '05

Hi! I'm another of those chuck users / hackers at Stacken, and just subscribed to the chuck lists. What is the current status on the 1.2 release? Is there anything I can do to help? I just compiled chuck (both "src" and "v2") on FreeBSD 5.4pre, to build with "make linux-oss" I had to: * Add -I/usr/local/include to FLAGS * Remove -ldl from LIBS * Added #include <sndfile.h> in util_sndfile.h, just before whats seems to be a copy of sndfile.h from a specific system. Is there any reason to copy in the file rather than including it? * Commented out the declaration of SF_FORMAT_SD2 (which was allready declared). I did exactly the same changes in both "src" and "v2". -- Rasmus Kaj --+-- rasmus(a)kaj.se --+-- http://www.stacken.kth.se/~kaj/ What we see depends on mainly what we look for

Well, I've done about as good a job as possible at screwing up this cross-list conversation. Anyway! Summary: Basically, the problem is that ChucK is a horrible realtime jack client (ie it zombies all the time) because the audio callback sleeps, waiting for ChucK's synthesis thread to finish. The solution is to make the audio callback thread the synthesis thread (ie make the audio callback drive all synthesis), eliminating this race. This is how things "should" be. Making the callback drive everything in a deterministic way would make ChucK a rock-solid jack client in realtime. I can see why this might be a nuisance though, because ChucK is probably driven by wall clock time (judging from the timing system of the language). It could be not that difficult though - I'm not sure how the ChucK vm core works yet, just the part that interacts with the audio callback. Essentially all we actually need is a function that can compute n samples of chuck audio on request. So I guess it comes down to either: a) It's possible - how to do it? b) It's not possible - why, and how can we make it at least a bit better? Cheers, -DR-

towards matching client / server messages in chuck
by chris turner 22 Dec '04

22 Dec '04

Hello All, I'm looking to build a minimal collaborative music production / jamming system using chuck + pygtk + possibly pyORBit2 if it is needed. basically, the flow is this : I see there being a 'live' chuck (remote) running in loop mode which is going to the 'house' mix, and independant workstations (local) running where people can edit shreds with the pygtk apps and preview them. Once they are satisfied with their previews, they can submit them to the 'live' mix. however, there are 2 missing features with that as of 1.1.53 : - as far as I can tell, it is not possible to synchronize the clocks of 2 chuck processes - submitting a shred to chuck in loop mode does not return an ID to the clients. The former means that 'remote' loops will not play in time with 'local' loops, and the latter means clients have no way of knowing which shreds they have submitted into the 'live' mix. I wasn't prepared to fix the first problem yet (big surprise :) ) so I went ahead and wrote this patch against chuck 1.1.5.3 for the second problem. (would have written it against -current, but didn't know about anoncvs) Basically, the second data field in the Net_Msg is filled with the return code of the desired operation (instead of the more global 'ok'/'nok' that seems to be stored in the first data field). I had to tweak the shred queuing a little bit so that the shred id was returned up the call graph, tweak the client such that it would actually print the corresponding message, and hold on to the initial message type for the print. I'll be happy to integrate it in a cleaner way with the cvs chuck if desired / add support for other status messages. Ideally, I'd like all the messages to match on the client and server, but I didn't want to go mucking around with the protocol without seeing how well it would be recieved / fit in with other plans. As a side note, I wasn't sure what 'immediate' mode was for shred submission, so I made all the shreds immediate as a test (because immediate shreds get an id at that point, which made it -much- easier to know the shred id : ) ) It seemed to have cleared up a strange bug whereby shred submission triggers an un-queued sound to play at the beginning of the new shred.. (developing on apple laptop, but can do linux/jack testing.. this patch has only been tested on osx) Thanks for the coolest audio thingy around.. it is exactly what I was looking for. - Chris

CVS commit pending... Autoconfuse almost done
by Mikael Johansson 16 Dec '04

16 Dec '04

Hey. We have now adapted the CVS snapshot from cvs.cs.princeton.edu to succesful builds with autoconf/automake. Before committing the changes; which include a few changes in directory structure and code; we'd like to announce the things that are changing here and showcase a patch and a tarball of the resulting structure. Both patch and tarball will be available at http://www.stacken.kth.se/~mik/chuck.tar.gz http://www.stacken.kth.se/~mik/chuck.diff.gz In addition, I'm appending the diff after the actual message and my signature in this email. The most fundamental changes are: * Moving the files out of notes/ and into the root of the repository. Autoconf expects to see THANKS, COPYING et.c. at the root instead of in some directory somewhere since the CVS structure is supposed to reflect the structure of the distribution tarball. * Adding a "audio=none" driver with empty declarations; complete with all relevant changes to make it work. * Putting a few of the uglier hacks within a #ifdef _WIN32 jail. * Throwing out all previous makefile.foo and makefile; in favour of a Makefile.am which generates a Makefile.in which generates a Makefile * Throwing out util_sndfile.[ch]. It's a really ugly hack that breaks most of the platforms we've been able to test on (including windows and MacOSX), and since libsndfile is available on all platforms anyway, it's presence is not really motivated. We've had success building at least with Autoconf 2.13, automake 1.8.5. In total, running the sequence ./HACKING ./configure --with-audio=foo foo being one of osx, alsa, oss, jack, win32 make make install makes exactly what you'd expect from it. This has been tested and verified on Linux/Gentoo, MacOSX and *BSD. Alas, we've been unable to make it build on MinGW, and unwilling to go through the changes that Cygwin applies; so we'd like for someone to try to build it and report on the problems. We will be available for questions and tips and tricks for coding autoconf-friendly here on the mailinglist, or by direct email. -- Mikael Johansson | To see the world in a grain of sand mikael(a)johanssons.org | And heaven in a wild flower http://www.mikael.johanssons.org | To hold infinity in the palm of your hand | And eternity for an hour Only in chuck_dev: AUTHORS Only in chuck_dev: COPYING Only in chuck_dev: ChangeLog Only in chuck_dev: DEVELOPER Only in chuck_dev: HACKING Only in chuck_dev: INSTALL Only in chuck_dev: Makefile.am Only in chuck_dev: Makefile.in Only in chuck_dev: NEWS Only in chuck_dev: PROGRAMMER Only in chuck_dev: QUICKSTART Only in chuck_dev: README Only in chuck_dev: THANKS Only in chuck_dev: TODO Only in chuck_dev: VERSIONS Only in chuck_dev: aclocal.m4 Common subdirectories: chuck_princeton/ckx and chuck_dev/ckx Only in chuck_dev: configure Only in chuck_dev: configure.in Only in chuck_dev: depcomp Common subdirectories: chuck_princeton/doc and chuck_dev/doc Common subdirectories: chuck_princeton/examples and chuck_dev/examples Common subdirectories: chuck_princeton/exile and chuck_dev/exile Only in chuck_dev: install-sh Only in chuck_dev: missing Only in chuck_dev: mkinstalldirs Common subdirectories: chuck_princeton/notes and chuck_dev/notes Common subdirectories: chuck_princeton/scripts and chuck_dev/scripts Common subdirectories: chuck_princeton/src and chuck_dev/src Common subdirectories: chuck_princeton/v2 and chuck_dev/v2 Only in chuck_dev/doc: Makefile.am Only in chuck_dev/doc: Makefile.in Only in chuck_dev/doc: chuck.1 Common subdirectories: chuck_princeton/examples/data and chuck_dev/examples/data Only in chuck_princeton/notes: AUTHORS Only in chuck_princeton/notes: COPYING Only in chuck_princeton/notes: DEVELOPER Only in chuck_princeton/notes: INSTALL Only in chuck_princeton/notes: PROGRAMMER Only in chuck_princeton/notes: QUICKSTART Only in chuck_princeton/notes: README Only in chuck_princeton/notes: THANKS Only in chuck_princeton/notes: TODO Only in chuck_princeton/notes: VERSIONS Only in chuck_dev/src: Makefile.am Only in chuck_dev/src: Makefile.in diff -ur chuck_princeton/src/chuck.lex chuck_dev/src/chuck.lex --- chuck_princeton/src/chuck.lex Thu Dec 16 23:28:09 2004 +++ chuck_dev/src/chuck.lex Thu Dec 16 23:28:25 2004 @@ -50,7 +50,7 @@ #include "chuck_errmsg.h" #ifndef __PLATFORM_WIN32__ - #include "chuck.tab.h" + #include "y.tab.h" #else #include "chuck_win32.h" #endif diff -ur chuck_princeton/src/chuck_absyn.cpp chuck_dev/src/chuck_absyn.cpp --- chuck_princeton/src/chuck_absyn.cpp Thu Dec 16 23:28:09 2004 +++ chuck_dev/src/chuck_absyn.cpp Thu Dec 16 23:28:25 2004 @@ -30,6 +30,7 @@ // Perry R.
