midi clock
by Kassen 22 Apr '06

22 Apr '06

Hi, list. At the moment I'm merrily ChucKing allong building a little "groovebox". My idea here is that it's easier to put knobs on a laptop then it is to put a comand line on a groovebox. The plan is to have one shred backed by a few sporked functions that will allow me to manipulate data in arrays using a midi controler (toggeling steps for beats, so far). Eventually this will use events to trigger the sounds in other shreds so those sounds could be re-compiled without ruining the data in the arrays. This is working nicely and seems like a good idea, even if at the moment it's not quite up to the level of a rs7000 or Live (yet!). For true groovebox functionality it would be nice to have some way of listening to a MIDI clock and this seems to be missing at the moment. Of cource MIDI sync normally works quite differently from the typical structure of ChucK code but at least some way of relating to it would be nice. I'd like to sugest some new function for this. What if we had something that would for example be able to output those midi clock "sync" pulses (I think they are properly defined as repeat "play" messages or something along those lines?) as events as well as the duration (in time) between the last two clock ticks of a incoming clock. Practically speaking it might be more sensible to average the time of -say- the last four of those, considdering how inacurate MIDI is and how quickly multiplied jitter might add up if looped. This would enable us to have chuck loops that would go something like; //wait for next sync event sync => now; //main loop while(true) { something_involving_realy_cool_beats; //advance my sequencer 1 +=> steps; (steps % 16) => steps; //advance time by a quarter note 24::click => now; } Now; this example would probably start drifting unless the duration of "click" was updated frequently by some external loop (thus averaging out the jitter) and even then some more advanced form of syncing the whole loop up every once in while would be preferable, especially if the external master clock will be modulated in mid piece.... Still; I hope this demonstrates that Chuck programs could relate to a MIDI clock in a way that's at least somewhat similar to the way they normally relate to the internal ChucK "now". Bad; Keeps MIDI alive while it realy should have died long ago. Good; Allows one to jam with friends who haven't yet realised MIDI should have been left in the 80's. Not all that complicated to implement, I imagine. Alternatively it would also be welcome to point me at where it says we allready have something like this; I looked and couldn't find a thing. Yours, Kas.

Remove duplicates from array
by David Powers 21 Apr '06

21 Apr '06

Hello everyone, I tried to send this earlier today, and it didn't seem to come through, but in the meantime I did more work on the problem. I am writing some functions that will be made into a class, for doing basic serial operations on cells (i.e. arrays of floats). The operations I have so far are: transpose, reverse, invert, permute, shuffle. The next function to finish is multiply, which does Boulez-style cell multiplication. For the function to work correctly, it should remove any duplicates from the array. Unfortunately, my brain's a little rusty right now. I'm sure I did this in the only computer class I ever took (C++). But I'm too sleepy to figure out the correct solution offhand, I think the ways I'm coming up with are inefficient. Can anyone help? My attempt at this is in the function remDup below, but I made some mistake, I'm sure relating to using a while loop--I'm not sure what the problem is though, or a better way to do it. I've gotten really spoiled, by usually coding these sorts of things in Python, where its amazingly quick to do list manipulations of any kind. //cellFun.ck public class Argh { fun static void print(float cell[]) { for (0 => int i; i<cell.cap(); i++) { <<< cell[i] >>> ; } } fun static void remove (float a[], int index) { a.cap()-1 => int newLength; float temp[newLength]; for (0 => int i; i < newLength; i++) { if (i<index) { a[i] => temp[i]; } else { a[i+1] => temp[i]; } } float a[newLength]; for (0 => int i; i < newLength; i++ ) { temp[i] => a[i]; } } //match fun static int match(float cell[], float element) { cell.cap() => int length; -1 => int position; for (0 => int i; i<length; i++) { if (cell[i] == element) { i => position; break; } } return position; } fun static float[] copy(float cell[]) { cell.cap() => int length; float newCell[length]; for (0 => int i; i<length; i++) { cell[i] => newCell[i]; } return (newCell); } //sort fun static float[] sort(float cell[]) { cell.cap() => int length; float temp; for (0 => int x ; x < length-1; x++) { for (0 => int y; y < length-x-1; y++) { if (cell[y] > cell[y+1]) { cell[y] => temp; cell[y+1] => cell[y]; temp => cell[y+1]; } } } return cell; } fun static float[] remDup(float cell[]) { 1 => int i; cell.cap() => int length; while (i < length-1) { if (cell[i]==cell[i+1]) { remove(cell,i+1); } else { i++; } } return cell; } }

Windows XP - setting chuck.exe to "realtime" priority
by David Powers 21 Apr '06

21 Apr '06

Hello, I'm new to ChucK, but I'm really excited about the possibilities. However, to get it to run well on my new Dell laptop running WinCrap XP, I had to go CTL-ALT-DEL, open up processes, and set the priority of chuck.exeto "realtime". Otherwise, when I create and delete shreds, I was getting unwanted glitching. Is there some way to automate this process, so that chuck always has realtime priority? A command line flag would be really helpful I guess. Also, is it normal for me to need to do this? Strangely, despite maxing out the CPU, on an old PIII desktop with only 256 MB RAM (as opposed to 1 gig on the laptop) I had no problems like this and creating and deleting shreds occurred very smoothly. That was with a clean install of WinCrap, however. So it may be the case that on the new Dell, the out-of-the-box install has processes running that are interfering with the audio. I know this might veer into off topic territory due to OS issues, so if anyone has insights specific to XP or Dells, feel free to email me privately. Thanks, David

durations and control structures
by Timothy Sutton 20 Apr '06

20 Apr '06

Hi there list, I'm new to this chuck business and am trying to get a handle on a number of things - timing and durations are one of them. If I have a chunk of code that I'd like to run for a specific duration of time, how could I go about defining this in the control structure? something like while (duration condition here) { do this } I understand that I could use some kind of counter that (de/) increments each iteration and use this to control the loop with a < or > operation, but one thing I might like to do in performance is vary the (poll rate) => now, and it would be nice for my control structure timing to remain intact with such operations. I'm sure there's a simple answer, but it avoids me. Thanks, --Tim

Opening Files, Reading Command Output, and Regular Expressions...
by DANIEL MAGNUSZEWSKI 18 Apr '06

18 Apr '06

(Inspired by my previous post) Is there currently, or any plans to implement, a way to open files (regular text/ascii files), running a command _and_ capture it's output (it seems that currently, the "system" function only returns an int - which I'm assuming is a return status), or use regular expressions within ChucK. Thanks! -Dan P.S - ChucK is awesome!

(OT) Toplap.org?
by Kassen 15 Apr '06

15 Apr '06

Dear list, Sorry to be a bit off topic but out of curiosity I tried subscribing to the Toplap "live-coding" list a while ago and this seems to be failing. Another thing that seems to be failing is "webmaster(a)toplap.org" to whom I tried to report this issue. My bet is that at least some people involved there will also be here so; Could somebody kindly give me a gentle push in the right direction? Sorry to bother you with this. Kas.

Re: [chuck-users] chuck - python
by DANIEL MAGNUSZEWSKI 12 Apr '06

I believe the command that you are looking for is: %> chuck ^ This prints the internal shred start at the listener VM, something like: [chuck](VM): status (now == 0h:2m:34s) ... [shred id]: 1 [source]: foo.ck [sporked]: 21.43s ago [shred id]: 2 [source]: bar.ck [sporked]: 28.37s ago (From: http://chuck.cs.princeton.edu/doc/program/otfp.html) I am doing something similar in Perl, so perhaps I can help you out. You can have your python script run this command on the shell (what OS are you running?) and grab the results (shred id, filename, etc) within that script. In Perl, it is done with the following code: @cmd_output = `chuck ^`; Then you can parse out the id number and run the following commands from the script to: Remove a shred ID: %> chuck - $shred_id _or_ Add: %> chuck + $shred_id _or_ Replace: %> chuck = $shred_id In Perl, assuming the above status output, the whole thing would look something like: # Get output from the chuck status command @cmd_output = `chuck ^`; # Parse IDs into shred_ids array @shred_ids = grep { /shred id\]:\s(\d+)\s/; $_ = $1 } @cmd_output; # Remove shred ID 1 (which is in the first array element) from the VM `chuck - $shred_ids[0]`; I hope this helps! -Dan >>> x(a)branwelt.de 04/07/06 6:24 AM >>> Hello I want to write a python program, that adds and removes (sporks) chuck-shreds to/from the chuck VM How to retrieve the shred-id ?

Hi! There is now a patched version of 1.2.0.5, which fixes issues with 'adc' UGen. Going to multichannel introduced a bug where adc first output a buffer of random values. Also the latency is now slightly better. If you are doing anything with 'adc', you should probably get the newest 1.2.0.5b: http://chuck.cs.princeton.edu/release/ Thanks and Sorry! Best, Ge!

I must be missing something
by Eric Gilbert 05 Apr '06

Hi, I want to use ChucK to control a bunch of MP3 files according to GPS data for a project that I am doing. However, I cannot seem to get sndbuf to open anything. I converted my MP3 files to WAV and AIFF (both of which look to be supported) with LAME, but still no luck. What am I missing?

miniAudicle: MAUI controls
by Mike McGonagle 03 Apr '06

03 Apr '06

Spencer, I was reading more about the MAUI stuff, and this sounds great. I was thinking and had a couple of questions and suggestions. Are you thinking about how these interfaces can be grouped into functional windows? It appear that currently there is a window for every control generated, and if some code gets executed twice, there are actually two controls for a single variable. Also, have you ever seen Ceceila ( http://cecilia.sourceforge.net/ )? It is a front end for CSound. One of the things that they have that is really nice is the ability to create Graphs, and each line in the graph represents a different variable to control. Having something like this would be extremely useful, especially when you are dealing with a lot of variables and controlling them over time.

Class Libraries, File Naming Conventions, and 'machine.add(...)'
by Mike McGonagle 30 Mar '06

30 Mar '06

Wow, Since the release of 1.2.0.5, I have been working with miniAudicle, and I really like what I see so far (up to this point, I had been using the commandline version of ChucK). So, I am not sure if there is a separate email list for the miniAudicle, or if I should send the email here, or to the Audicle list... so... One thing that I am trying to do is set up my Class Libraries in a fashion where I point miniAudicle to the root directory, and I put my stuff into a directory structure as follows: Package/ClassLibrary/Make.ck Where 'Package' represents a folder of my libraries, 'ClassLibrary' is the name of the particular library, and the 'Make.ck' file is used to load the individual library files in the order needed by calling 'machine.add(...)' on each of the files. In doing this, I was hoping to be able to enter the following in my program file so that the Mask library gets loaded: machine.add("mjm/Mask/Make.ck"); So, this works when I have just this line in a file, and all the class files get loaded in the proper order. BUT, once I put any additional code into this file, it will not load the class files at all (and this was after restarting the miniAudicle to ensure that there wasn't any conflict with previously loaded classes). Here are the issues that I see so far... (1) Would it be possible to allow for miniAudicle to have multiple paths that it would search for finding these libraries? (2) Am I using 'machine.add(...)' for its intended purpose (in loading classes)? Might there be a good reason to add another 'machine.load(...)' that does the same thing as 'add', except it does not spork a new shread for each call? This 'load' function could also be made to keep track of what files have been loaded, and any time there is a file that gets loaded more than once, any subsequent loads could just be ignored? (This might also change the miniAudicle interfact to include a button to load, in addition to the other buttons.) Would this function be best named 'load'/'include'/'import'? Which one? (3) Any thoughts on why the classes do not load when I have subsequent code in my program (after the 'machine.add')? I could send you an example of what I am trying to do, but this would require sending out my libraries, and I would prefer to sent those out as archives so that the directory structure is maintained.

Getting the keys for an associative array
by Mike McGonagle 22 Mar '06

22 Mar '06

Is there a way to get all the keys that are used as indices into an associative array? I was wondering if this is something that is in the works, or is it already available? I was thinking something like... ************* Object myAssociativeArray[0]; new Object @=> myAssociativeArray["first"]; new Object @=> myAssociativeArray["second"]; myAssociativeArray.keys => string keysList[]; for(0 => int i; i < keysList.cap(); i++) { <<< () => myAssociativeArray[keysList[i]].printObject >>>; } ************* Also, would there be a way of ensuring some sort of order inwhich the keys are returned (ie, the order inwhich they were added to the array???)?

Converting dB to chuck .gain
by Graham Percival 09 Mar '06

09 Mar '06

What is chuck's .gain measured in? Neither std.dbtorms() nor std.dbtopow() seem to work... I have a bunch of data about a sound, (frequency, dB): 86.132812, 9.996495, 172.265625, 6.996109, 258.398438, -0.955794, 344.531250, -11.900859, ... and I'd like to try some additive synthesis in chuck. The first value (frequency) is obvious, but I'm at a loss as to what to do with the second value (dB). What's the conversion factor between dB and .gain ? Cheers, - Graham

setDelay too big !

hi list i have some crash with this patch with this output: [chuck](via STK): DelayA: setDelay(1856.88) too big! i tried to debug, routing my signal without the PitchShift and/or without the JCRev, but it crashes anyway i guess it's because of the JCRev unit or perhaps it's because of my use of manipulating time, which could be not really academic... here's the patch Sitar s => PitShift sh => JCRev r => dac; //init rev, gains 0.9 => r.mix; 0.6 => s.gain; 0.5 => sh.gain; //lfo pitchShift freq sinosc shFreq => blackhole; 1.0 => shFreq.freq; //init sitar freq 280 => float temp; while (true){ 1.0 => s.noteOn; //variation pitchShifting (shFreq.last() * 10 ) => sh.shift; std.rand2f(0.0, 0.8) => sh.mix; (std.randf() * 20) +=> temp; temp => s.freq; 10::ms => now; }

hi thanks for hints and links about sound technique i'm running chuck "dracuuulaaa" on an ubuntu breezy with an ingo molnar's realtime patched 2.6.15 kernel (finally after a painful way...%] ) i've much better results regarding latency (my jack server runs with a buffer of 2x256 frames) than the build-in kernel ones. > Hi, > > I just ran the patch for 10 minutes without it crashing.
