Running scripts sequentially
by Gonzalo 06 May '14

Hi, I'm trying to run multiple .ck files sequentially. Specifically I have a 'master' file that loads all the 'child' files via Machine.add. But then of course they run concurrently. For now I'm just advancing time in the master file before every Machine.add statement (ugly...). Is there a way to accomplish this nicely? Thanks! Gonzalo PS: This is my first message to this list. I'm working on a project with Chuck that raises *a lot* of questions, so I'll probably be coming back here often. :)

chuck vm options

Hello list. 1) Catching up a bit, it occurs to me that shell%> chuck --start `while(true) 1::second +=> now;` has been superseded by shell%> chuck --loop ; correct? Does ChucK any longer accept subprocesses or so, from the shell? 2) Also if anyone cares to distinguish or give an example for --callback Utilizes a callback for buffering (default). --blocking Utilizes blocking for buffering. then I'm much obliged as this is unfamiliar in some respects to me.

Oscillators of type (XXXOsc) do accept direct input from other UGs for Phase or Frequency. You just have to set the .op mode for those. In general, UGs don't accept sample-rate ChucK connection for arbitrary parameters, as very often one doesn't really want or need those to run at the sample rate. Control rate is arbitrary in ChucK, so to update the .freq of something non-Osc type, you would make a shred that does it at your sub-sample rate. You could even do it at the sample rate, of course. Here's an example: Flute f => dac; 880.0 => float freq => f.freq; spork ~myMod(); 1 => f.noteOn; 1*second => now; 660.0 => freq => f.freq; 1*second => now; 440.0 => freq => f.freq; 1*second => now; fun void myMod() { SinOsc s => blackhole; 6.0 => s.freq; while (true) { freq * (1.0 + 0.05*s.last()) => f.freq; 10 :: ms => now; // whatever rate you like here } } // Cheers!!!

curious about chuck -- very basic question
by Aaron Bohannon 17 Apr '14

After reading through the relevant parts of the language specification, I am unable to determine whether it is valid to use the chuck between a unit generator and a variable/property, like this: SinOsc s => dac; SinOsc lfo => s.freq; Obviously, anyone who's used hardware synths is going to want to do that sort of thing. I'm sure this has been discussed and debated a hundred times on this list before, so feel free to send me a link to someone else's answer. I just couldn't find any search terms that would pinpoint the issue. Thanks, Aaron

Hello again. I am undertaking as of next month a series of livecode workshops in Atlanta, in which I expect to teach or demo a fair amount of ChucK. I'd very much appreciate hearing what your teaching | learning experiences in ChucK may have been. I've mined a lot of existing ChucK material, but I certainly appreciate examples as well. Naturally I will give full authorship credit insofar as I receive it, to any borrowed examples. Thank you. Al Matthews - http://fatmilktv.com Atlanta, GA, US +1 337 214 4688
