Expanding MIDI support
by Mario Buoninfante 05 Jul '19

05 Jul '19

Hi everybody, One month ago I got started with an Open Source project whose goal is to support some hardware on various platforms/environments/programming languages (Pd, SC, Processing, Lua, Python, JS, etc.) and of course my goal is to have ChucK on board as well (hopefully I'll share more info about the project in the next months). The only issue I've got at the moment is that I need to talk SysEx with these gears, and as you know ChucK doesn't deal with SysEx. I really care a lot about this project, mainly because it's open source and because will involve different communities (Pd, SC, JS, etc.) and would really love to include ChucK in this since is the tool I'm mainly using to experiment and make music and I truly believe has got something more than other languages/environments. Thus, since I'm not a C++ person, I decided I'll ask a colleague of mine (a C++ programmer) to help out with this, also because he'll get involved in the project for other reasons anyway. But before doing this I wanted to ask the developers and all those who are involved in maintaining ChucK, if there's any particular reason why SysEx messages are not currently supported. >From what I can see in the code (and after running few experiments) with the current architecture SysEx messages could be sent out (3 bytes at time though) but with a lot of limitations (didn't manage to receive SysEx messages though). Also, I think RtMidi doesn't gate us from doing that (there's just a flag used to 'turn on/off' SysEx communication). But it seems like there's nothing in place that allows to deal with MIDI messages bigger than 3 bytes and, from a "non-C++ person", it seems one way to fix this could potentially be to add a SysExIn/SysExOut and a SysExMsg classes that deal with these kind of MIDI messages. Of course there could be a lot of things I'm missing here, and that's why I'm asking you for some help, even before asking for other help :) Just to make sure there's nothing that prevents people from adding this functionality. Then, last but not the least, ChucK is an open source project and I love it. There are a lot of people working with it, and I was wondering whether or not this would be a feature people are after. Basically I'd like to hear from the community before even getting started with this. I hope this makes sense. Looking forward to hearing from you guys :) Cheers, Mario

how to use MIDI clock in ChucK
by Michael Heuer 03 Jul '19

03 Jul '19

All, I'm curious how to use MIDI clock effectively in ChucK, in two main use cases: From a sample-rate-based timer in ChucK, how should I send out MIDI clock? while (true) { 10::ms => now; // send MIDI clock } or TimeSignature.common(120) @=> TimeSignature ts; while (true) { ts.e => now; // send MIDI clock } or (this one allows the caller to modify the tempo later) TimeSignature.common(120) @=> TimeSignature ts; ts.eighthProvider() @=> EighthProvider e; while (true) { e.evaluate() => now; // send MIDI clock } From receiving MIDI clock messages from an external source, how should one adjust the BPM in ChucK? MidiIn min; MidiMsg msg; TimeSignature.common(120) @=> TimeSignature ts; while (min.recv(msg)) { // if is clock … { /* new BPM */ => ts.tempo; } } I would imagine I would want to window over the last n clock messages to average? Thanks in advance, michael

Working on the next version of my ChucK vscode extension
by Forrest Cahoon 29 Jun '19

29 Jun '19

I'm working on a new version of my vscode extension for chuck that will run chuck to check for diagnostic errors. I've got a basically working but not ready for prime time version in the syntax-checker branch of my github repo: https://github.com/forrcaho/vscode-chuck/tree/syntax-checker Note that this will require a chuck built from the latest sources at https://github.com/ccrma/chuck because I'm using the new `--syntax` switch which was just added to run chuck just for syntax checking. If you are interested in taking a look (and maybe helping out), please do so. This is my first vscode extension, so I'm still just figuring things out. Forrest

Mini Audicle build error
by Ranjith Hegde 20 Jun '19

20 Jun '19

Greetings, I am new to ChuCK and miniaudicle. I joined the course on Kadenze to learn. I use linux laptop. The build is Ubuntu Studio 19.04. I was able to build chuck without errors using the tutorial from the website. I, however, encounter the following error when I try to build miniaudicle. I understand that it does not support qt5 which is why I replaced it with qt4 and qt4-dev. I still get the following error.

Makey Makey and miniAudicle (Windows)
by Mario Buoninfante 13 Jun '19

13 Jun '19

Hi David, Could it be matter of permissions? On Linux I remember initially I had something similar, then I gave miniAudicle and ChucK the right permissions and everything was fine. I don't remember how to check this on Windows off the top of my head, maybe try to run miniAudicle as administrator and see if it works. Out of curiosity, can you run the examples in the 'hid' folder? Cheers, Mario

Is there a way to run chuck to just check syntax?
by Forrest Cahoon 13 Jun '19

13 Jun '19

I'm looking at trying to add more to my ChucK vscode extension, and I'd love to be able to run chuck on the code being edited so that I can parse and highlight the errors. However, I don't know how you would run chuck to just generate syntax errors. I see there is a --silent switch, which would work for the purpose, but would be an unnecessary waste of resources just to get the possible syntax errors. Csound has a --syntax-check-only command-line option. Is there something like this for ChucK? If not, would it be straightforward to add one? Forrest

Makey Makey and miniAudicle (Windows)
by David Loberg Code 12 Jun '19

12 Jun '19

I am in Germany, trying to teach a workshop with ChucK and Makey Makey devices. It is no problem with OSX laptops. However, on PCs, miniAudicle doesn't recognize Makey Makey as an HID. The laptop in general detects the MakeyMakey as a keyboard (e.g., I can type with it in a text document and it works as an interface with the online MakeyMakey piano https://apps.makeymakey.com/piano/). But I can't run Chuck programs in miniAudicle. We have tried these installation instructions without success: https://learn.sparkfun.com/tutorials/makey-makey-quickstart-guide#windows-i… Any other advice? davd ----------------- David Loberg Code School of Music Western Michigan code(a)wmich.edu

How to integrate Chuck into my own program?
by Da Xu 07 Jun '19

07 Jun '19

Hi guys, Since, I am not developing for Chuck itself, so, I thought this might be a more appropriate place to ask this question. Is it possible to integrate Chuck into a program that I am writing? Basically, I would like to utilize Chuck's strong time nature to create a custom clock plugin for another environment, specifically Touchdesigner. TD is great for visuals, however, for audio related stuff, its clock can be bit unstable. It has a feature which allows external programs to communicate with it via a shared memory block, which would be the fastest way to get info into TD without overheads like protocol decoding. My goal is to create a custom clock(s) generator to send pulses into TD via the shared mem block. So, my question is can I use Chuck in this way? And how would I go about doing that? I know this is a rather simplistic use of Chuck, but I really like Chuck's strong time nature, its concurrency abilities and being particularly lightweight. I searched the documentations, and didn't really find anything. So, any info would be greatly appreciated. Thank you! Da.

LiSa.feedback behavior
by Gregory Brown 30 Apr '19

30 Apr '19

Hello all — I'm working with the LiSa.feedback parameter and it doesn't seem to be behaving as expected. I was assuming 0 would be "keep nothing when overdubbing" and 1 would be "keep everything." This doesn't seem to be the case; it seems to be default to something near 50%. I have confirmed that I am changing the property but the behavior seems to be stuck at the default. I have tried value as high as 100, which gives some crackling, but no change in behavior. Can anyone shed some light on this? Thanks in advance, Greg

question: import/export functions and classes
by Gianluca Casati 27 Apr '19

27 Apr '19

Hi All, I am new to this mailing list, I am an italian mathematician working in IT since 2005. I used chuck some time ago (around 2009?) to generate music with prime numbers and it was great! I really like ChucK, both features and syntax. Now I would like to create a collection of chuck programs to do some live coding and having fun with music. I am really excited, as a mathematician, about the fact that ChucK supports complex numbers. There are some features I look for in a programmin languange and complex numbers are a nice to have. Another feature I usually look for is packaging, I was reading documentation and it looks like (or at least I could not find) a way to import / export a function or a class. For example I would like to create a folder with some functions and classes and reuse them with some sort of export / import: is that possible currently in chuck? For example, a function that iterates, I don't know, for example with Julia's formulas, could be used by different instruments, so it would be handy to define it in a file, say it julia.ck, and import it in other ChucK files. Cheers,Gianluca.

chuck serial arduino weirdness
by Scott Smallwood 23 Apr '19

23 Apr '19

Dear chuckians, Not sure how many of you have messed with the serial objects - but I’m having a bit of a head-scratcher and wondered if anyone had any ideas about this. I built a little box with one knob and one switch - which I’m planning to use as a master volume and mute switch for a multichannel audio installation that is running in Chuck. The Arduino code is really basic: — const int SwitchPin = 12; const int VolPin = 0; void setup() { //turn on serial communication Serial.begin(57600); //set switch pin and turn on pullup resistor pinMode (SwitchPin, INPUT); digitalWrite (SwitchPin, HIGH); } void loop() { Serial.print(digitalRead(SwitchPin)); Serial.print(' '); Serial.println(analogRead(VolPin)); delay(50); } — OK - so I first built a little Max patch to test it, which works flawlessly as far as I can tell. I then wrote a little chuck script, based partially on one of Spencer’s examples. It simply grabs the data and prints it to the console. It works great for awhile, but after a few minutes, it always crashes with an array-out-of-bounds exception: NullPointerException: (array access) on line[35] I’m grabbing two ints, and looping through and printing them out. Why is the array size suddenly getting mucked up here? It’s intermittent, and sometimes doesn’t happen for several minutes, but always results in a crash eventually. Any ideas?? (chuck code below) — SerialIO.list() @=> string list[]; SerialIO cereal; //the name of my arduino box's serial port "usbserial-12DP0657" => string port; //number of serial device -1=>int device; //loop through any ports and find the one with the right name for(0=>int i; i < list.cap(); i++) { //check for correct port name if (list[i].find(port) != -1) { //and assign the device number i => device; } else -1 => device; } //open the serial port cereal.open(device, SerialIO.B57600, SerialIO.ASCII); //loop through and grab the serial port data while(true) { cereal.onInts(2) => now; cereal.getInts() @=> int ints[]; //print out to console for(0=>int i; i < ints.cap(); i++) //<- this is where the problem seems to happen { chout <= ints[i] <= " "; } chout <= IO.newline(); } —ss [ - ] Scott Smallwood <http://www.scott-smallwood.com/> - Associate Professor - University of Alberta [ - ]

FLOSS Manual update
by mario buoninfante 09 Apr '19

09 Apr '19

Hi, I just added 2 chapters (and updated an existing one), to the ChucK FLOSS manual (https://en.flossmanuals.net/chuck <https://l.facebook.com/l.php?u=https%3A%2F%2Fen.flossmanuals.net%2Fchuck%3F…>). * Array Object Functions * String Object Functions * Other Objects Reference (added FileIO and SeriaIO) There's still 'some' work to do to make the FLOSS manual really comprehensive, but we'll eventually get there Next step would probably be a bit of text formatting. Especially in the various 'reference' sections, there are too many 'styles'. Just a quick note about the FLOSS manual and ChucK documentation in general. What I always found difficult (especially at the begin of my adventure with ChucK), was the fact the the documentation wasn't centralized. There are plenty of places on the internet where you can find bits and bops, but none is really comprehensive (some are outdated, some just incomplete, and so on). I believe ChucK is now mature enough and needs a fully comprehensive (and official) documentation. The FLOSS manual could help with that (my personal opinion, open for discussions :) ). Wouldn't be easier if there was THE place where all the documentation is? Looking forward to hearing from you. In the meanwhile, give me a shout if you wanna help with the FLOSS manual, there's still plenty to do :P Cheers, Mario -- Electronic Musician, Creative Coder, QA Engineer https://vimeo.com/creativecodingsalerno http://mbuoninfante.tumblr.com/ https://github.com/mariobuoninfante https://bitbucket.org/mariobuoninfante/

issue adding elements to an array
by Mario Buoninfante 28 Mar '19

28 Mar '19

Sorry, this is the right code that shows 'the issue': function static void insert_1( string array[], string x, int pos ) { string mom_arr[0]; if( pos < array.size() && pos >= 0 ) { for( pos => int c; c < array.size(); c++ ) { mom_arr << array[c]; } x => array[ pos ]; array.size( array.size() + 1 ); for( 0 => int c; c < mom_arr.size(); c++ ) { mom_arr[c] => array[ c + pos + 1 ]; } } else if( pos == array.size() ) { array << x; } } function static void insert_2( string array[], string x, int pos ) { string mom_arr[0]; if( pos < array.size() && pos >= 0 ) { for( pos => int c; c < array.size(); c++ ) { mom_arr.size( mom_arr.size() + 1 ); array[c] => mom_arr[ c - pos ]; } x => array[ pos ]; array.size( array.size() + 1 ); for( 0 => int c; c < mom_arr.size(); c++ ) { mom_arr[c] => array[ c + pos + 1 ]; } } else if( pos == array.size() ) { array << x; } } ["a", "b", "c"] @=> string s_1[]; insert_1( s_1, "ONE", 1 ); for( 0 => int c; c < s_1.size(); c++ ) { <<< s_1[c] >>>; } <<< "" >>>; ["a", "b", "c"] @=> string s_2[]; insert_2( s_2, "ONE", 1 ); for( 0 => int c; c < s_2.size(); c++ ) { <<< s_2[c] >>>; }

issue adding elements to an array
by Mario Buoninfante 28 Mar '19

28 Mar '19

Hi, I suspect I'm probably doing something stupid and just not realizing it, but I don't understand why these 2 functions ("insert_1" and "insert_2") are giving me 2 different results: function static void insert_1( string array[], string x, int pos ) { string mom_arr[0]; if( pos < array.size() - 1 && pos >= 0 ) { for( pos => int c; c < array.size(); c++ ) { mom_arr << array[c]; } x => array[ pos ]; array.size( array.size() + 1 ); for( 0 => int c; c < mom_arr.size(); c++ ) { mom_arr[c] => array[ c + pos + 1 ]; } } else if( pos == array.size() ) { array << x; } } function static void insert_2( string array[], string x, int pos ) { string mom_arr[0]; if( pos < ( array.size() ) && pos >= 0 ) { for( pos => int c; c < array.size(); c++ ) { mom_arr.size( mom_arr.size() + 1 ); array[c] => mom_arr[ c - pos ]; } x => array[ pos ]; array.size( array.size() + 1 ); for( 0 => int c; c < mom_arr.size(); c++ ) { mom_arr[c] => array[ c + pos + 1 ]; } } else if( pos == array.size() ) { array << x; } } ["a", "b", "c"] @=> string s_1[]; insert_1( s_1, "ONE", 1 ); for( 0 => int c; c < s_1.size(); c++ ) { <<< s_1[c] >>>; } <<< "" >>>; ["a", "b", "c"] @=> string s_2[]; insert_2( s_2, "ONE", 1 ); for( 0 => int c; c < s_2.size(); c++ ) { <<< s_2[c] >>>; } It seems like expanding an array with '<<' instead of using .size(int n) is giving me some problem.
