Hello! I searched with google "music programming language" and found ChucK. ChucK sounds good but I have some problems: 1) I got error: *** Fatal error : sizeof (off_t) != sizeof (sf_count_t) *** This means that libsndfile was not configured correctly. with examples which uses sndbuf for opening wav-files 2) With many programs from http://wiki.cs.princeton.edu/index.php/ChucK_Programs I got errors like [hihat.ck]:line(38): cannot cast to type 'int' from 'dur'... This examples wrong? Or only development version of ChucK has this features? My system: Linux kernel 2.6.11.1, ChucK 1.1.5.6c Sorry for bad english. -- registered Linux user #360474 Don't worry, I can read OpenOffice.org

Hello, again > Try looking in another terminal and running top with your favourite > flags ( I like -d). You may find that these UGENs are sucking a lot of > cpu power and that may be the culprit. This 5 channels take 25-30% of CPU only but I get bad sound when all 5 channels begin play. For example: --- BeeThree a => dac; BeeThree b => dac; BeeThree c => dac; BeeThree d => dac; BeeThree e => dac; 1.0 => a.noteOn; 1.0 => b.noteOn; 1.0 => c.noteOn; 2.0 => d.noteOn; 2.0 => e.noteOn; fun void p(float freq1, float freq2, float freq3, float freq4, float freq5, dur del) { freq1 => a.freq; freq2 => b.freq; freq3 => c.freq; freq4 => d.freq; freq5 => e.freq; del => now; } while (true) { //Here sound is normal p(100.0, 100.0, 100.0, 0.0, 0.0, 100::ms); p(100.0, 200.0, 100.0, 0.0, 0.0, 100::ms); p(100.0, 300.0, 100.0, 0.0, 0.0, 100::ms); p(100.0, 400.0, 100.0, 0.0, 0.0, 100::ms); p(100.0, 500.0, 100.0, 0.0, 0.0, 250::ms); //Here I hear some noises p(100.0, 100.0, 100.0, 100.0, 500.0, 100::ms); p(100.0, 200.0, 200.0, 250.0, 250.0, 250::ms); p(100.0, 300.0, 300.0, 100.0, 500.0, 100::ms); p(100.0, 400.0, 400.0, 250.0, 250.0, 250::ms); p(100.0, 500.0, 500.0, 100.0, 500.0, 100::ms); } --- > Your two solutions to that problem are less fancy patches or a new > computer...
