Initial download risk or just joking?
by Edward Herbst 04 Aug '10

04 Aug '10

Can someone please advise if someone is being facetious or is there really a risk in the download? When you click the Download link the first paragraph reads: "ChucK-1.2.x.x is part of the Dracula release of ChucK - why Dracula? While the previous release (Frankenstein/1.1.x.x) offered the proof of concepts (timing, concurrency, on-the-fly programming) with a generous propensity to explode, the Dracula release is more refined and powerful with the addition of arrays, objects, events (and better explosions too). Additionally, the Dracula release is yet unoptimized and may suck all blood and life from your computer (anticipate spectacular crashes and other bloody disasters)... Please let us know if that happens. " - Show quoted text -

Command Line Options in patch
by miquel parera 03 Aug '10

Hello. Sorry for the very basic question: In the command line options (chuck:2:3) the me. function retrieves 2 & 3 like strings, but i want ints. Any function for transforming like a.toString() but a.toInt() ? Thanks,

What is the state of the ChucK code site? - I should perhaps post the tuning systems programs I made. Hans

Re: [chuck-users] Multiple Output

I think you should try changing the pop-up menu to the left of the frequency one to 8 channels. Or something. The system may make a choice for 2 channels for you which your unit also supports, and then ChucK can't do that choice.

Hi, I've a sound card with 8 outputs (4 left and 4 right) and I want to send different audio signals to each output. Is this possible with chuck? Thanks -- Patrick Guido Arminio

eChucK Update
by Les Hall 10 Jul '10

10 Jul '10

Hi all, To clarify about the eChucK project, I am not running ChucK on the boards that I have created. What I do is run miniAudicle on my Mac mini and code up test programs that consist of ChucK code that is specifically written to mimic actual hardware analog and digital circuits. Then I play around with the ChucK model until I am happy with it, then convert the ChucK program into electronic circuit form. Hence eChucK for electronic ChucK. I cleared the name with Ge a long time ago, he seemed to think it was a cool idea. This first circuit board is a modular synthesizer board that implements a Karplus Strong algorithm using analog circuitry. KS has been implemented in many forms including ChucK, but as far as I know this is the first modular synthesizer board that does it. The next planned board will use a simplified version of the KS circuit and a Boolean Sequencer to create a little song generator with headphones out and five dials to alter the music. That one will be a stand-alone product that anyone can buy or build without having a modular synthesizer or anything. Well, that's the update, hope I cleared things up . Les

eChucK Lives...
by Les Hall 09 Jul '10

09 Jul '10

Hi Chuckists, I just wanted to mention that this eChucK project lives on, converting ChucK algorithms into circuit boards. I just got done preparing a batch of 22 boards for mailing out to customers around the world. This one is a modular synthesizer product only intended for people who make their own modular synthesizers. The next project will be a "Credit Card Synth", a little mini synth that makes great sounds in the form factor of a credit card (though thicker of course). Well, just wanted to say hi and report on progress, good day! Les

Timing Issue
by Timothy Leonido 29 Jun '10

29 Jun '10

Hello, I have to preface this by saying that I may be missing an obvious answer, but what object will allow me to wait for an amount of time before a shred is active? Usually I set the gain to zero (on the otf 7 patch) for a few phrases and that works fine: after a minute, I can have a snare drum come in for a chorus. Though I'm afraid that there's a more logical way to do this... Thanks

For Dan
by Kassen 18 Jun '10

18 Jun '10

Fellow ChucKists, Yesterday I wanted to wish Dan a happy birthday on FaceBook, hoping for many more years of fun with strings and code but thought it'd be nicer to write this in ChucK. Then stuff happened and I was too late. Belated but no less sincere; emulating strings in LiSa... because we can, and because LiSa can (LiSa can actually do anything, she's just modest). We start out with a very literal implementation of Karplus-Strong at concert A4 tuning. Then we start mucking with various parameters in ways that are less traditionally Karplus-Strong for some more interesting tembral effects. Yours, Kas. /* Do copy, do share. No warranties, no refunds. Physical models can (and will!) blow up; please mind your speakers, neighbours and pets. Remixing and sharing results strongly encouraged (many parameters left....). Happy belated birthday to Dan! */ //the patch (noise or a saw plus a envelope could emulate a bow instead of a pluck) Impulse i => LiSa l => dac; //needs to be defined second => l.duration; //two voices for averaging 2 => l.maxVoices; //buffer duration = source of the pitch second / 440 => dur base_cycle; //create a looping delay //looping for both recording and playback is on by default base_cycle => l.loopEndRec; l.loopEnd (0, base_cycle); l.loopEnd (1, base_cycle); 1 => l.record; //offset the second voice by one sample //so we average between the current and the last sample value l.play (0, 1); l.playPos (1, -1 * samp); //"::" should work here but gives me a error?
