getting started questions
by Steve Morris 28 Oct '13

28 Oct '13

I'm new to ChucK but am very excited. I have grand plans. I will likely have lots of questions (some unfortunately stupid, apologies in advance) although I have been pouring through manuals, examples, the wiki, git source code and forum archives. Hopefully my questions won't be too annoying. I'm always happy to receive answers in the form of pointers to documentation I should be reading before wasting the groups time. Here's my first pass. 1) I can't find any thing that documents the scope of variables and objects. Can I create variables that can be accessed in other files, other threads. 2) My first project will be fairly large hopefully split between many files. Where can I look to see how ChucK code should be broken down and organized. What is a good paradigm for a shared library. 3) Speaking of libraries I would like to bring a lot of existing C++ code into my project. Does dynamic linking actually work. I see vague (old) references to it being made to work again as if it was broken and other references to it just needing documentation which will come "soon." Lacking documentation is there an example library that does it. I can get a long ways with a working example. Working code may be confusing and slow to understand but it is its own most accurate documentation. I've looked at chuck_dll and I think I need to see the interface from the other side to really understand. I'm happy to be a reviewer for "preliminary" draft documentation. 4) The Mac install seems to have installed a single bundled app. How do I use the command line interface? Thanks, -steve (aka zencuke)

Minor bug when saving an example with "save as."
by Steve Morris 27 Oct '13

27 Oct '13

Hi. I'm new to ChucK and love it so far but I would like to report what I think is a minor bug. I'm on a Mac running OSX 10.8.5. miniAudicle "about" reports: version 1.3.0 (gidora) Copyright (c) Spencer Salazar ChucK: version 1.3.2.0 (chimera) 64-bit Copyright (c) Ge Wang and Perry Cook http://chuck.cs.princeton.edu/ Bug report: Note: this is low priority and minor, more in the category of an annoyance. I opened an example then saved it with "save as." Then I edited it then tried to save the changes. A dialog reported the file was read only. I checked the file with info and the file has Read & Write permission. I can overwrite it with "Save As" but Save refuses to save. I suspect that the example was read only and it kept that attribute in some file state variable. If true this is wrong in two ways, first it should have updated the local state to match what it wrote and second it should not depend on historical information. Even if the file was read-only when opened that may have changed. This is a multitasking system and some other task (me in finder for example) might have changed the permissions since the file was opened. I believe the correct behavior would have been to attempt to write the file and check the error status of the write. Best regards and thanks for a wonderful tool. -Steve Morris aka zencuke > >

is 'string' a primitive type?
by Kiran O.V. 23 Oct '13

23 Oct '13

Hi When I click 'add shred' with the following code: public class A { static string a; } it throws following message: [*unnamed1]:line(3): cannot declare static non-primitive objects (yet)... [*unnamed1]:line(3): ...(hint: declare as ref (@) & initialize outside for now) as if string is non-primitive. And when I follow the suggestion and use a ref public class A { static string @ a; } it throws the following message: [*unnamed1]:line(3): cannot declare references (@) of primitive type 'string'... [*unnamed1]:line(3): ...(primitive types: 'int', 'float', 'time', 'dur') as if string is a primitive type. Is it a code limitation or am I doing something wrong? Thanks in advance! Kiran

turn off midi clock on osx
by Michael Heuer 15 Oct '13

15 Oct '13

Hello, I am using ChucK to send MIDI to a MeeBlip micro http://meeblip.com/use-one/assembly-guides-legacy-models/micro-kit-assembly/ through some cheap MIDI-over-USB device which uses a generic driver on OSX. Unfortunately the MeeBlip can't handle incoming MIDI clock/timing data and it seems to be receiving such even though I'm not sending any via ChucK. Is there a way to disable MIDI clock in ChucK, or in OSX, or both? Thank you, michael

All of those instruments contain noise. Likely a Noise object. Wonder if Noise itself does a seed? I'll check.

Re: [chuck-users] Non-random random number

Apparently, the non-random bug does not happen after declaration of all STK instruments, just some of them: BlowBotl, BlowHole, Clarinet, Flute, Saxofony, StifKarp, VoicForm And the problem occurs with both Std.rand2 and Std.rand2f (I haven't conducted any more tests yet to see under what other conditions it might happen.) david > Forgive me if this was already discussed on the list before.

Non-random random number
by David Loberg Code 09 Oct '13

09 Oct '13

Forgive me if this was already discussed on the list before. I am puzzled about a non-random random number. When the random number is calculated right after an STK instrument is declared, the result is not random. It is the same number every time. However, if the same code occurs without an STK declaration before it, the result is random. while (true) { StifKarp stu => dac; int randy; Std.rand2(0,10) => randy; <<<"here are three random numbers", Std.rand2(0,10), Std.rand2(0,10),Std.rand2(0,10), "and NON-random Randy", randy >>>; Std.rand2(0,10) => randy; <<<"here are three more random numbers", Std.rand2(0,10), Std.rand2(0,10),Std.rand2(0,10), "and random Randy", randy >>>; 1000::ms => now; } david David Loberg Code School of Music Western Michigan University 1903 W Michigan Ave Kalamazoo, MI 49008-5434 code(a)wmich.edu

Wah-Wah "pedal"
by Perry Cook 08 Oct '13

08 Oct '13

Hey all, There was some recent discussion over on the STK users list, about implementing a Wah-Wah pedal. I hacked together a simple one based on experiments and data that Julius O. Smith did using his own personal CryBaby Pedal. For more on that: > https://ccrma.stanford.edu/realsimple/faust_strings/faust_strings.pdf Here's my quick version in ChucK, using just his three data points, interpolating between. Enjoy!! I'm going to hook it up to a MIDI pedal shortly.
