FaucK - issue with 'v' methods
by Mario Buoninfante 19 Mar '19

19 Mar '19

Hi, I'm using the FaucK chugin and I don't know why when I use the 'compile' method to load a Faust script, then I cannot change the parameter in it (ie my_faust.v("param", value) ). The same script, when 'embedded' in the ChucK code using 'eval', works fine. I also tried specifying the entire path of the parameter, but doesn't seem to work (ie "Folder/MyFaust/param"). Does anyone have the same issue? I tried on MacOS Sierra. Cheers, Mario

Re: [chuck-users] Convolution Reverb (Posed by: Julien Saint-Martin)
by Perry Cook 03 Mar '19

03 Mar '19

If the impulse response is short enough, or real-time isn’t important, then the FIR chugin can be used. FFT-based convolution is possible using the FFT/iFFT UANAs, but latency and real-time are issues. To deal with that, It would be possible to factor into a nice systolic topology using shorter FFTs and delay lines to line everything up. I don’t know of a specific chugin or example other than those.

Gen10 issue with odd harmonics
by mario buoninfante 23 Feb '19

23 Feb '19

further testing shows that it's not about the odd harmonics, from the 5th harmonic (6th partials) onwards, sometimes you get unwanted sidebands with odd harmonics, sometimes with even ones. I'm monitoring the output (DFT) with Baudline and I tried driving Gen10 at different frequencies. -- Electronic Musician, Creative Coder, QA Engineer https://vimeo.com/creativecodingsalerno http://mbuoninfante.tumblr.com/ https://github.com/mariobuoninfante https://bitbucket.org/mariobuoninfante/

Gen10 issue with odd harmonics
by mario buoninfante 23 Feb '19

23 Feb '19

Hi, I found out that Gen10 has an issue with dealing with odd harmonics (not fundamental). It's easy to repro simply taking the example code and using the following coefficients instead: g10.coefs( [0., 0., 0.5] ); - shows the issue g10.coefs( [0., 0.5, 0.] ); - doesn't show the issue Hooking ChucK up to a spectrum analyzer it's easy to see the difference. In case there are odd harmonics, there are a lot of unwanted partials/sidebands, instead of having only the components specified in .coefs(). Gen9 doesn't seem to have this issue.

Re: [chuck-users] Routing SndBuf (Skot)
by Perry Cook 19 Feb '19

I don’t remember SndBuf ever being multichannel. In fact, there is a SndBuf2 just for stereo. That UG can be chucked to dac for auto stereo, or allows access to .chan(#) for arbitrary routing. SndBuf mixes everything down to mono, and I fear there is no support for > 2 channels via SndBuf. If my statements above are true, then Someone could do us all a cool favor by making a SndBufN chug.

hey Casper thanks! I think the issue may also be in the statement if (i%iMax > jCount ) 0.0 =>s.gain; which is not the same as if (now%iMax > jCount ) 0.0 =>s.gain; because I don't think "now" increments at the same rate as i (I wonder if now increments one sample at a time, rather than .1 ms at a time, then they become equivalent, thus your fix.).

Hello Chuck users (and gurus). This is my first message to the list. I'm a complete newbie, but I think I would enjoy using miniAudicle with the Faust chugin (FaucK). So It could be a question for developers. I'm an experienced Linux user. I compiled ChucK 1.4.0.0, the latest and greatest Faust, all the chugins (including FaucK) and miniAudicle. Unfortunately, FaucK give me this error (on the command line and with miniAudicle): chuck examples/flute.ck [flute.ck]:line(5): undefined type 'Faust'... [flute.ck]:line(5): ... in declaration ... Any pointer would be appreciated. Marc N.B. I first sent this message to the chuck announcement list, so please ignore.

FYI here's the code: https://github.com/charliekramer/ChucK/blob/master/WIP%20call%20and%20respo… It's weird because I'm not using DelayL in my code (but I guess it's in one of the STK models--I'm using Saxofony and Bowed). The message seems innocuous--it seems to continue running fine. It doesn't occur right away but after the code's been running for a little while. Just curious if I'm doing something weird.

Why is my code doing this?
by Forrest Cahoon 04 Jan '19

04 Jan '19

Sorry, I tried to come up with a more hello-world example of the problem I'm experiencing, but I really don't know what's going on so I have to post something a bit complex. My ChucK code is here: https://gist.github.com/forrcaho/21acdb25e05a8620f56dba591cd52ed5 I have a class called AdditivePartial and one called Additive which contains an array of AdditivePartial objects. The Additive objects play method sporks the play method for all its partials. The first Additive object I create appears to ignore the noteAmplitude I have set; it is pegged and clipping. That is, until the second Additive object is sporked, at which point the first object suddenly "remembers" it's noteAmplitude. I've looked at the output in Sonic Visualiser and that confirmed this is what's happening, at least on my linux machine. Can anyone reproduce this behavior, or does it work for you? If you can reproduce it, what the heck is going on? Forrest

running() doesn't return status of the shred

SysExIn and SysExOut classes
by Mario Buoninfante 19 Dec '18

19 Dec '18

Hi, I made 2 simple classes that allow to send/receive SysEx messages on ChucK: https://bitbucket.org/mariobuoninfante/sysex/src/master/ All they do it's basically sending/receiving messages via OSC to/from Pure Data that deals with actual SysEx messages. It seems to work fine, but I didn't do any 'stress test'. Of course having to convert from/to OSC is a kind of a bottleneck, so I'd expect some 'performance issues' when dealing with big SysEx messages (ie firmware updates) , but I think it's fine for general purpose SysEx transmissions. I'd like to see, one day, these 2 classes (SysExIn and SysExOut) being part of the ChucK source code as members of the MIDI classes family. Let me know if you have any question. Cheers, Mario

Gen10 issue with coefficients

Hi, I'm working with the Gen10 UGen and it seems like once I set up the coefficients, I can't change them on the fly anymore. To be more precise I can only add new sines to the table but I can't get rid of the ones that are already there. Here's an example where I try to remove the fundamental, but I can't Phasor phasor => Gen10 g10 => Gain volume => dac; volume.gain(0.1); g10.coefs([1.]); 0 => int c; while(true) { if(c==3) { g10.coefs([0., 0.,0.,0.,1.]); <<< "table update" >>>; } Math.random2f(500,700) => phasor.freq; c++; second => now; } When I update the table, instead of removing the 1st partial and add the 5th, I end up having both 1st and 5th. I had a quick look at the source code (ugen_osc.cpp, row 1469) and the possibility of having a coefficient equal to 0 is not considered. Would it be better if we could remove partials?

The length of papers is 4 to 8 pages, with up to 5 keywords, including an abstract of up to 200 words. The abstract will be published on the conference website once the paper has been accepted. The full paper will be available on the website during and after the conference. All papers are peer reviewed by a committee of experts from different disciplines. Reviewers may suggest improvements to the author(s), or require changes in order to accept the submission. The duration of the presentation is 25 minute followed by a 5 minute discussion. *Poster Papers* Poster papers must be written in English, should be 2-4 pages, with up to 5 keywords, including an abstract of up to 150 words.
