Hi, i'm a german nerd/musician and i'm plaing with chuck atm. I succesfully compiled the latest release for jack support. But it seems chuck has some RT issues. running the mand-o-matic example i get a cpu load of about 2-3% but xruns nonetheless. I run jackd at a buffer size of 256 frames atm (which is plenty huge for my standards. i.e. i use 16 or 32 frames to apply realtime effects to my guitar via jack-rack - completely xrun free. This is a nicely tuned realtime preemption system with a delta 66). I heard there's a 1.2 version in cvs. Does it have this kind of problem also? BTW: i get quite a few clicks/pops on moving windows/etc. even w/o RtApiJack: audio overrun/underrun reported! and xruns. But there's quite a few of these, too. Inspecting ~$ ps -C chuck -cmL PID LWP CLS PRI TTY TIME CMD 23421 - - - pts/6 00:00:07 chuck - 23421 TS 24 - 00:00:04 - - 23422 FF 109 - 00:00:02 - it seems to my uneducated eye, that chuck has two threads. One running SCHED_FIFO (probably the jack process() thread) and another SCHED_OTHER thread. Maybe the RT thread often waits for the SCHED_OTHER thread which gets starved by other cpu activity (like moving windows, etc) If this is a RTFM! issue i will be happy to accept pointers.

std.mtof?
by jesus gollonet 18 Jul '05

hi world. i've been dabbling for a while with chuck now, and have a little doubt i've seen this in various of the provided examples (this one is from the band-o-matic.ck // pentatonic 2 * std.rand2( 0, 4 ) => int freq; if( freq == 6 ) 7 => freq; if( freq == 8 ) 9 => freq; std.mtof( (float)( 21 + std.rand2(0,5) * 12 + freq ) ) => band.freq; if ( std.randf() > 0.7 ) std.rand2(0,3) => band.preset; } and i see that it generates a pentatonic scale (in fact i've used it as provided and works). But i don't really understand how it works. i can get the first three lines, but i don't now what std.mtof is for, so i can't guess what it is for. any kind helping hand? thanx a lot. the deeper i know chuck, the more i love it!! cheers!

http://www.zenlinux.org/~zen/reactive_states/Reactive_States_-_The_Infinity… Alot of the audio is synthesized using ChucK. This is DnB experiment #2. -- echo "wbk=wbkifkru+lod" | perl -pe 's/(.)/chr(ord($1)+3)/ge' "See, what a scourge is laid upon your hate, That heaven finds means to kill your joys with love." --William Shakespeare (Romeo and Juliet Act 5 Scene III)

Reactive States

I was using Live for this project, but i've recently decided to give ChucK a try as i have been using it on my other project Artifact. Turns out ChucK works really well for tracking DnB. Haven't tried out anything complex like a darkstep track yet, this is pretty laid back DnB. http://www.zenlinux.org/~zen/Reactive_States_WotW.mp3 enjoy. -- echo "wbk=wbkifkru+lod" | perl -pe 's/(.)/chr(ord($1)+3)/ge' "See, what a scourge is laid upon your hate, That heaven finds means to kill your joys with love." --William Shakespeare (Romeo and Juliet Act 5 Scene III)

RBF-soft. [producing] working with chuck

Hi to everyone!, Hi Chuckit list! We're David & Ivan Rodriguez, RBF-soft. [producing], Electronic Artists from barcelona - Spain. We presented our last work VIFE _alpha v.01 at NIME'05Vancouver - Canada. VIFE _alpha v.01 is a Virtual Interface to Feel Emotions. The performer user can control 6 three dimensional sonorous forms with an interactive glove (VIFE _glove v.01) & an anlaysing box (R-CUBE IV). The works investigate the idea of Synaesthesia and her enormous possibilities creating new realities, sensations and zones, where the user can find new points of interaction. In NIME'05 we knew *Ge* *Wang* and *Perry* *Cook*. So interesting people ;) :) After that we presented this project in SONAR'05 (Barcelona), too. For our next project, we're working with Chuck like a sonorous engine. Chuckis so powerfull and don't need any visual interface, only the console. This is very important for our next work, because we need to save resources and energy to use it in other things like, analysis of audio, synthesis, sonorous effects,... This project is about wearable technology, GPS, sensors,... We will use Chuck for this project. Best Regards, rodri_DJ & ivan_VJ RBF-soft. [producing] http://www.rbf-soft.com rbf_soft(a)hotmail.com
