ChucK scripting language for Audio/MIDI testing
by mario buoninfante 05 Nov '18

05 Nov '18

Hi, Has anyone ever used ChucK for audio/MIDI testing? I personally used it in more than a couple of occasions, and I found it really useful. Nowadays, also for audio and MIDI, Python is pretty much the standard language for testing. Actually it is quite powerful, especially considering the number of libraries available, but despite its versatility and easy of use, I found it a bit annoying for audio/MIDI testing. It seems to me that languages like ChucK and Pure Data are better candidates for this kind of job. I've been using Pd for testing for almost 2 years now (from regression to semi-automated tests), and I'm really happy with it. No need to configure anything more than the essential, pretty stable and reliable, multi-platform, etc. Then, recently I started doing the same with ChucK, that of course has some advantages being a "text-based" language rather than a graphical one. In the specific I've been using it to talk with a CLI via Serial (hardware testing). Perfect, stable, reliable, the possibility to easily manage events... in short, brilliant! I think it would be perfect for test automation as well! The only missing thing is a full MIDI implementation (I know, I said that something like 5 billions times here on the mailing list, and I'm sorry I'm being "a bit" boring). But, SysEx messages are crucial nowadays. A lot of gears use it for basically everything from data transmission (patches, bootloader/firmware updates, etc.) to parameters control (from DX7 till the most recent Korg Volca series), plus internal functionalities. I think this is the real bottleneck at the moment, and I hope one day it will get "fixed". Anyway, I'm saying this for 2 reasons. First, I'd like to get some feedback from you guys and see if anyone else has been doing similar things. Second, I think start using ChucK for audio/MIDI testing could be really good for ChucK itself and its community. I don't know, maybe that's just me thinking about stupid things, but I suppose if people (and when I say people I also mean companies) start using ChucK for work reason, the amount of support increases as well. There will be more users for sure, that means more beta testing, and probably more support in developing it as well. cheers, Mario -- Electronic Musician, Creative Coder, QA Engineer https://vimeo.com/creativecodingsalerno http://mbuoninfante.tumblr.com/ https://github.com/mariobuoninfante https://bitbucket.org/mariobuoninfante/

data sonification with Chuck?
by Panos Amelidis 25 Oct '18

25 Oct '18

Hello All I want to explore data sonification in the context of making music pieces and/or sound installations. At the moment I am going through reading the Sonification Handbook and find it quite fascinating. I have no experience whatsoever on DS and to be honest I find it to be quite a difficult task. But, I am... determined to get a result… If any of you would like to share some thoughts, directions or examples that would be much appreciated. I have some experience with Chuck but I used to work a lot with MaxMSP (and some supercollider experience as well, mainly using it for audio files manipulation). I am willing to improve my competence in Chuck though. Thank you all in advance for the help! best ~panos

Hi, I ran the same simple test on my Linux machine (Asus i5-6198DU 2.30 GHz, 8 Gb RAM - Ubuntu Studio 16.04) and here I've got different results: SndBuf x 50 - 15.3% CPU usage SinOsc x 50 - 15.7% CPU usage What could explain this? cheers, Mario

Chunity v1.0.1 released + VSCode Syntax Highlighting Plugin!
by Jack Atherton 24 Oct '18

24 Oct '18

Dear all, Chunity version 1.0.1 is now up on the Unity Asset Store. This version contains internal bugfixes and also implements a retry system if you get your requests for global variables slightly out of order. http://u3d.as/1bvM or download the unitypackage directly from http://chuck.stanford.edu/chunity/files/Chunity_v101.unitypackage Also, I'm happy to announce that there is now a Chunity plugin for VSCode! You can install this to modify the definition of the C# language in VSCode to do embedded ChucK syntax highlighting every time you use the Chunity function RunCode(). Example: https://i.imgur.com/GdBilc1.png https://marketplace.visualstudio.com/items?itemName=jatherton.chunity Many thanks to Forrest Cahoon, who wrote the original ChucK VSCode plugin, which is a dependency for the Chunity plugin. https://marketplace.visualstudio.com/items?itemName=forrcaho.chuck As always, happy ChucKing!! Best, Jack + the ChucK team Music:Computing:Design @ CCRMA

SinOsc UGen
by Mario Buoninfante 24 Oct '18

Hi, I tried using SndBuf instead of SinOsc (both on Rasp Pi and a MacBookPro), but SinOsc seems to offer better performances. On the Mac (2.7 GHz Intel Core i5, 16 GB 1867 MHz DDR3, MacOS Sierra 10.12.6), running the code you'll find below, I've got this CPU usage (I used top from terminal to check the CPU usage): SndBuf x 50 - CPU usage 24.0% SinOsc x 50 - CPU usage 16.4% the same seems to happen on Rasp Pi 3, despite I had to use 25 oscillators to avoid glitches. here's my code ------------SinOsc Version------------ SinOsc s[50]; for(0 => int c; c<s.size(); c++) { s[c].gain( (1/( s.size()) $ float) * 0.25); s[c] => dac; } while(true) { for(0=>int c; c<s.size(); c++) { Math.random2f(300, 500) => s[c].freq; } 200::ms => now; } ------------SndBuf Version------------ SndBuf s[50]; for(0 => int c; c<s.size(); c++) { s[c].read(me.dir() + "/sine_1024.wav"); s[c].pos(0); s[c].loop(1); s[c].gain( (1/( s.size()) $ float) * 0.25); s[c] => dac; } while(true) { for(0=>int c; c<s.size(); c++) { Math.random2f(300, 500) => s[c].freq; } 200::ms => now; } ------------------- cheers, Mario

SinOsc UGen
by Mario Buoninfante 24 Oct '18

24 Oct '18

Hi, As already pointed out by someone else here, I noticed we've got the SinOsc UGen that doesn't use a wavetable but instead uses the sin function. I don't know what the reason behind this decision, but I was wondering whether it would be possible to also have a variant that uses wavetable as well. I presume that would help a bit in terms of performances, and I think it would be useful in scenarios where ChucK runs on platforms like Raspberry Pi. cheers, Mario

Re: [chuck-users] Sine Wavetable (Mario B.)

I’ve done this a lot. Just make a nicely oversampled single-cycle sine .wav file and use SndBuf. You’ll need a .freq function that does the right thing based on how many samples are in your wavetable. I think you can also use GenX to do it.

outputing stereo Gain to different dac output?
by henrique matias 15 Oct '18

15 Oct '18

Hello i have a soundcard with multiple outputs ( 32 ) when i use normal Gain g => dac; I get a stereo signal, but if i do: Gain g => dac.chanel(31) i get sound only on 31 and not on 31 and 32. What's the right way of patching "stereo" out of a different pair on the dac? sorry for such basic question, when i looked for "Gain" on the documentation i could not find anything about patching it "stereo", perhaps i looked on the wrong place? Thank You -- *time's not passing, you are.* ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁ ❂ ❁

You’ll need to connect your gain explicitly to channel 32 as well. Gain is a mono UG, but there’s special treatment when connecting any mono UG to the system default stereo dac. Note that if you want true “stereo” gain control or panning, you can do: Gain g[2] => dac; or Pan2 p => dac; but for multichannel you’ll have to hook up each channel individually.

issues using the mouse with chuck / ubuntu 16.04
by Pablo Tassi 12 Oct '18

12 Oct '18

Hi guys, I'm having some issues when I try to use the mouse with chuck, e.g. 0 => int deviceNum; Hid hi; HidMsg msg; if( !hi.openMouse( deviceNum ) ) me.exit(); gives: HidIn: couldn't open mouse 0... I've tried to change the rights sudo -c 'chmod u+r /dev/input/*'; without sucess... I'm using Ubuntu 16.04. Any hints? Many thanks, Cheers
