Translation of a simple csound orchestra

2010-02-09T10:47:45Z

Hello !
I'm learning supercollider after years of using csound. I'm having trouble translating this orchestra to supercollider.
-------------------
instr 1
inote = p4
iamp = p5
kenv linseg 0,p3*.15,1,p3*.65,.25,p3*.2,0
a1 oscil kenv*iamp,inote,1
out a1
endin
-------------------
f1 0 65536 10 1

i1 0 4 55 4000
i1 4 2 110 5000
i1 6 1 220 4000
i1 7 1 440 5000
i1 8 4 220 5000
i1 12 2 110 4000

e
----------------------------

What bothers me is I don't know yet how to reproduce the relationship between the score, the duration of the event, and the envelope.

Thanks

RoundButton Kills SC3 (with a knife... in the parlor...)

2010-01-25T18:56:24Z

Hi all,

I experience a crash 100% using the new "round" gui classes. Using the RoundButton class on an empty sc construction window will cause an immediate crash. If, however, there are already elements in the window, an immediate crash will not occur, but will occur eventually. I can post crash reports if it would help. In the meanwhile, I've posted the system log output below. Is this happening to anyone else on Blow Leopard?

System: 10.6.2

Crashes on SC Version:
Custom builds (latest svn and older svn builds i found in the attic)

partch tonality

2010-02-09T05:15:56Z

hi, we were discussing tonality diamonds (most associated with harry
partch) at the sc meeting last night. i'd never heard of them before.
as it was mentioned that jmc had posted some example code to
illustrate this concept, i tracked it down and posted it to the wiki
page for our meeting, so it can be easily found: http://
supercollider.tsd.net.au/Mtg20100208

based on information from http://www.deandrummond.com/zoomprimer.htm
i made this patch today in order to better understand the pitch
ratios. i hope the info i have based this on is correct and attach
the code in case someone else wants to explore this fascinating
subject. if i've misunderstood anything i'd appreciate any critique,
thanks.
also if there are any other patches out there that cover similar
territory, i'd be interested to check them out.

The Plot. (was plotting behaviour) : Quark or Common?

2010-02-08T11:26:00Z

Here is a suggestion for a new standard plot window in SuperCollider. If it doesn't perform well on different computers/systems, it could also be made a Quark. It would be good to hear how it works on netbooks/PPC and on SwingOSC.

PlotWindow is easily extendible from with SC, gives level information and supports plots of up to three dimensions. It can be embedded in UserViews and supports specs for both axes.

I have now called the plot methods plot2, as not to interfere with what exists under plot. But if it works fine, it would perhaps be a good idea to replace the old one.

Playing synchronized Patterns on different machines

2010-02-08T03:11:05Z

Dear list,

we tried different approaches/Quarks to synchronize 4 laptops playing
patterns but nothing really worked. We need our "1" synchronized, and
it would be cool if one person could change the tempo, but it would be
sufficient to just syncrhonize to a common known tempo.

TelepathicClock had some glitches, the tempo always tends to get
slower and sometimes it get's really fast and crashed our system. We
could not reproduce the glitches so it wasn't really usefull.

We looked at OSCClock, but we couldn't really figure out how they wark
or what to do.

At the moment we sycnrhonize by hand with the RedTapTempoGUI. It
wokrs, but it's tedious.

Is anyone running a simillar setup or has an idea how this could be
done easily? Setting the tempo remotley with OSC is not a problem, but
we couldn't figure out how to force a Clock to restart a messaure or
to sycnhronize the position in the messaure (so our patterns are out
of sync).

We hope somebody has a tip for us.

yours
Patrick (and the Mandelbrots).

Github

2010-02-06T17:31:54Z

Hey Guys!

I figure since we're all working on code here and there's a lot of collaboration going on, it may be useful to save and share (and branch!) our working projects on Github.

http://github.com/mrproxxxy/Supercollider is mine.

Anyone have anything else going right now?

playing with scel

2010-02-08T18:58:52Z

Just some fun things I was toying with today.

- I wasn't happy with the default font (I hate Courier!) and found out how to change it in ~/.emacs.

(set-default-font "terminus-iso8859-9-12")

To find the name of the font, I wrote a quick linuxy font browser. I just love that you can do this kind of crap so easily in sc :)

(
var f, x, l, w;

f = Pipe("xlsfonts | grep iso8859-9", "r");
if(f.isOpen) {
    protect {
        x = List.new;
        while { (l = f.getLine).notNil } {
            x.add(l);
        };

        w = Window("fonts", Rect(0, 25, Window.screenBounds.width, Window.screenBounds.height-25));
        l = ListView(w, Rect(2, 2, w.bounds.width - 4, w.bounds.height - 4))
        .items_(x)
        .action_({ |view|
            var cmd = "xfd -fn '%'".format(x[view.value]);
            cmd.postln;
            cmd.unixCmd;
        });
        w.front;
    } { f.close };
} { "Pipe couldn't be opened.".postln }};
)

- After reducing the font size (for my 600px-high netbook monitor), I got more lines in emacs by:

    (add-to-list 'default-frame-alist '(height . 40))
    (add-to-list 'default-frame-alist '(width . 90))

- A question/suggestion - ~/.emacs enables skeleton pair insertion for ` and <, which is not really helpful for SC syntax. This is on puredyne - not sure if that's a typical default or something that scel sets.

- Tabbing - why can't I add tabs after the prescribed indent? Is there a way to apply tabbing to a whole region, not just one line at a time?

Thanks,
hjh

sc svn: furniture will be rearranged this week

2010-02-08T09:44:03Z

Hi -

Just a warning so no-one gets any shocks: later this week I'm
intending to rearrange the svn trunk of supercollider a little, as
discussed in a recent sc-dev thread.
http://permalink.gmane.org/gmane.comp.audio.supercollider.devel/23290

Nothing will be deleted but the main build scripts will move slightly
(eg the mac xcode stuff will move into a 'mac' folder). The various
build scripts will need updating to reflect the changes, but that
should happen pretty quickly.

[OT] gig recording

2010-02-08T04:29:59Z

hi, i had my live debut the other week and here is the recording:
http://www.mediafire.com/?oz2mzztjoky
it's all live sc synthesis. the performance is a bit rough, not
everything went to plan and there are loads of unwanted glitches,
although they often aren't that noticeable under the intended ones...
anyway i hope it entertains someone.
p.s. it sounds loads better on a massive sound system! also you may
wish to ponder the extremely cold conditions in the venue at the
time, it was way below zero and with only a couple of feeble heaters
to go round, frostbite didn't seem far off.

Networking with ProxySpace

2010-02-07T15:38:37Z

Hi all,

I have run into a problem that I can't seem to figure out. I was wondering if anyone might have a good idea or if anyone else has dealt with this sort of thing.

We have three computers that need to share data with each other over the network and we are all utilizing ProxySpaces.

We would like to share some of our control data but I am having trouble finding any way to continuously send data from a NodeProxy out to others. I tried SendReply.kr but found that it would start choking after sending at a rate of about 6 messages per second.

for instance if I wanted to send the values of an XLine.kr to another computer:
~values = {XLine.kr(340,200,20) };
~sender = {SendReply.kr(Impulse.kr(2), \scott, ~values.kr, 1905) };

Anyone know any way to do this?

Thanks,
-Scott

jack + supercollider realtime zombie problems

2010-02-07T08:59:36Z

Hi there,

In my continuing exploration of SC on Linux, I've run into a problem when using SC with Jack when Jack is in Realtime mode. I can run pretty much anything i want when not in realtime, but when in rt running the following code i get the zombified error.

b = Buffer.alloc(s, 512);

Ndef(\tool, {

var in, freq, hasFreq, pvLoad, pvAnal, pvIfft, comb, out;
//baseFreq;
in = Mix.new(SoundIn.ar(0));
pvLoad = FFT(b, in + Ndef(\tool));
pvAnal = PV_NoiseSynthF(pvLoad, 21.123);
pvIfft = IFFT(pvAnal);

# freq, hasFreq = Pitch.kr(in, ampThreshold: 0.02, median: 1);
out = PitchShift.ar(in, 0.08, (pvIfft+Ndef(\tool) * freq).abs.poll, 0.0, 0.0, mul:2);

comb = CombC.ar(out+Ndef(\tool), 10, 0.3, out.abs.value);

Out.ar([0,1], comb);

});

Ndef('tool')
zombified - calling shutdown handler
UGen(UnaryOpUGen): 0
JackDriver: killed by jack
RESULT = 0

I'm running Ubuntu 9.10 with kernel 2.6.31-9-rt on an Asus EeePC 900a.

The only information I could find on this error was from a forum unrelated to SC that said that the "zombified" error occurs when the program interfacing with Jack can't keep up with Jack's realtime scheduling, so Jack is forced to drop it from the 'processing graph' but the program remains registered.

I imagine there may be something i should probably have in my startup file, but like i said, i'm a n00b with SC on Linux, so help is appreciated.

Thanks for helpz.

Hello

I can't find this

#() is a float (9.5228539861432e-309), but what is its use in the lang?

envbufnum and GrainBuf

2010-02-06T21:58:15Z

Hey all,

I have this SynthDef...

SynthDef(\granulate, {
arg outbus, bufnum, trigRate = 1, grainDur = 1, grainRate = 1,
pos = 0, interp = 2, envbuf, amp = 1;
var trig = Impulse.kr(trigRate);
var sig = GrainBuf.ar(
numChannels: 1,
trigger: trig,
dur: grainDur,
sndbuf: bufnum,
rate: grainRate,
pos: pos,
interp: interp,
envbufnum: envbuf,
mul: amp
);
Out.ar(outbus, sig);
})

And am attempting to call it like this:

var buf = Buffer.read(s, "~/sounds/trayne.wav".standardizePath);
var basicWindow = Buffer.loadCollection(s, Env([0, 1, 1, 0], [0.01,
0.98, 0.01], [5, -5]).discretize);
Synth(\granulate, [\outbus, 0, \bufnum, buf, \trigRate, 20, \envBuf,
basicWindow, \amp, 0.05]);

When I do this I get weird, sort of garbled, high-pitched output as
opposed to what I would except. When I run the same set of code but
removing any mention of the envbufnum and letting GrainBuf supply its
own window buffer, things work fine. This is a hair confusing. I'm
running revision 9590 on 10.5.7. Am I just missing something basic?

Thanks,
Sam

2010-02-06T09:57:50Z

Hello list,

I'm looking for the definition of the .plot method. In the help file for .plot it says that it is implemented in ArrayedCollection, but when I look in the source file for this class I can't find it in there. Anybody knows where I can find it?

Actually, what I want to do is to implement a custom plot method, but I guess I can just extent ArrayedCollection for this:

+ ArrayedCollection {
customPlot {
}
}

Am I right?

Hiho,

I am just getting this error when trying to boot SwingOSC... (first output)
I'm getting a similar error trying to open a socket with Processing (second
output)...

Any idea what could be the problem?

sincerely,

SendTrig for loop station

2010-02-03T02:39:06Z

Hi there!
I almost finished my Arduino/SC Loop-Station (gonna make a HOW-TO afterwards..) ... Now I want some fancy LEDs blinking with the rhythm. It works so far, but the LEDs are not in rhythm when I change the looptime and speed. So I need a synchronization mechanism. I found SendTrig. It should send a message to an OSCresponder each time the loop starts again. I integrated it into my "loopPlayer"-Synth and it looks like this now:

  SynthDef("loopPlayer", {
    arg out=0, bufnum=0, speed=1, looptime=1, gate=1;
    
    var playDir = (((-1 * speed) / speed.abs) + 2).mod(3); //change the direction on neg. speeds
    var playFreq = (looptime  / speed.abs).reciprocal;
    var playDur = BufRateScale.ir(bufnum) * s.sampleRate * looptime;
    var loopFunc = VarSaw.ar(playFreq, 0, playDir).range(-0.001, playDur);
    var bufPlay = BufRd.ar(1, bufnum, loopFunc, 0, 4);

    SendTrig.kr(A2K.kr(loopFunc), 0, 1);  //send a trigger message for sync. each time the loop starts

    Out.ar(out,
      Pan2.ar(
        Median.ar(3, bufPlay),
        0.0,
        EnvGen.kr(Env.cutoff(0.1, 1), gate, doneAction: 2);
      )
    );
  }).store;

And the responder for testing:

    OSCresponder(s.addr,'/tr',{ arg time,responder,msg;
      [time,responder,msg].postln;
    }).add;

The thing is that it only triggers once at the beginning and I don't understand why! I tried it out with some test values like this:

(
  { SendTrig.kr(A2K.kr(VarSaw.ar(1, 0, 1).range(-0.001, 1)), 0, 1) }.play;

    OSCresponder(s.addr,'/tr',{ arg time,responder,msg;
      [time,responder,msg].postln;
    }).add;
)

And then it works, but sometimes it just skips for exactly 6 seconds... Did I understand something wrong with the SendTrig object? I set the range to a start value of -0.001, so that it should trigger each time when it passes this value and comes to a positive value again, right?

SC 3.3.1 release candidate 2 for windows

2010-02-06T06:30:14Z

Hi all -

A new release candidate of supercollider for windows, please feel free
to try it:
<https://sourceforge.net/projects/supercollider/files/Windows/3.3/supercollider-installer-3.3.1winRC2.zip/download>

Among other things this contains updated SwingOSC (0.64). If it seems
usable then it'll become the standard 3.3.1 for windows.

SCUserView-relativeOrigin

2010-01-29T16:39:45Z

relativeOrigin is deprecated
SCUserViews with relativeOrigin=false take _far_ more CPU to refresh than otherwise.

In other words is the relativeOrigin stuff in SCUserView::draw final, because frankly, it sucks.

Running out of letters

2010-02-05T09:33:29Z

Hi everybody,

Simple thing that I can't figure out:

I'm working on something that requires a lot of different Playbufs as well as many GUI buttons. My playbufs are defined as:

x = Synth("PlayBuf1", [ \bufnum, 0, \rate, 1,]);
z = Synth("PlayBuf2", [ \bufnum, 11, \rate, 1,]);
q = Synth("PlayBuf3", [ \bufnum, 13, \rate, 1,]);
e = Synth("PlayBuf4", [ \bufnum, 14, \rate, 1,]);

and then another 22 GUI buttons using the remaining letters of the alphabet. Yet I need more Playbufs and more buttons! I though defining them something like "aa" and "bb" would work but no.

Any thoughts?

Yours

Gary Mentanko

Network Music Concert this weekend

2010-02-04T10:47:23Z

Hi list,

Just wanted to let you all know about a concert that will be happening this Sunday (after the superbowl). Digital Sunrise of the New Era is a live concert happening at Montana State University and Mills College involving new pieces made with sc and processing. The concert will be performed live from both locations by sending OSC over the internet via OscGroups. If you happen to be near Bozeman, MT or Oakland, CA on Sunday at 7:30pmCMT or 6:30pm PST then you should drop by. It's free and it's SuperCollider! See the links below for more information.

Additive Resynthesis

2010-02-04T17:13:05Z

Hi all,

I'm trying to wrap my head around the FFT UGens. Specifically, I'm looking for something similar to Csound's pvsadsyn opcode, which resynthesizes pvsanal data using an oscillator bank. I'm under the assumption that IFFT does not do this.

Thanks,

Blake

UGens information

2010-02-04T22:24:06Z

Hi

Is there any SC method for getting information on specific UGens,

such as number of inputs/outputs in the ugeGraphFinc, the controls, showing the ugens etc. ???

thanx,

NetAddr weirdness

2010-02-05T01:31:18Z

hi, consider the following example:

r = OSCresponder(nil, "/test", { |t, r, msg, addr| [t, r, msg, addr].postln; addr.hostname.postln; addr.dump; } ).add;

NetAddr("127.0.0.1", 57120).sendMsg("/test", "Hello");

if i post the addr that is passed to the OSCresponder, i get something which looks like it tells me the hostname and port:

a NetAddr(127.0.0.1, 57120)

however, if i ask this instance of NetAddr for its hostname, i get nil.

i found a solution, which is to get the addr and do asIPString:

addr.addr.asIPString.postln

however it seems weird to me (and a fellow collider fwiw) that the NetAddr doesn't allow access to this in the first place, despite its report. is there a good reason for this, or is it a language glitch?

Hello List,

Can anyone tell me how to change the port to which the language will respond to OSC messages.

sclang - error in command handler

2010-02-03T04:53:28Z

hello

after using revision 9590 for a while, i wanted to try the latest svn
(rev 9737) (mostly to see if SwingOSC recent issues were solved).
it builds just fine (with default scons options) but when I launch
emacs, I have this error:

(*SCLang:PostBuffer*)
/quit sent
quit done
*** SCLang finished ***

--

(*Messages* buffer)
...
SCLang: Initializing library...
SCLang: Indexing help topics ...
Loading cl-seq...done
Loadingcl-extra...done
SCLang: Indexing help topics ... Done
SCLang: Error in command handler

I did a fresh svn checkout, removed my .sclang.** files but it doesn't help.
am I missing something obvious ?

cheers,
_y

ps: I'm running puredyne-9.10

scheduler que is full.

2010-02-03T19:05:36Z

With my latest project, which heavily uses routines, I am getting the
error "scheduler queue is full.".

I can comment out some of the routines and the problem goes away - is
there a way to expand the scheduler queue or do I need to refactor my
code to use fewer routines?

Warning request

2010-02-04T13:03:03Z

Hello

Is it possible to put some warning in the post window when the packets
doesn't rich the server?

like in this case

(
SynthDef(\tmuch, {
var out = {
SinOsc.ar(rrand(100, 1000));
}!1000;

Out.ar(0, Mix.new(out) * 1/1000);
}).send(s);
)

x = Synth(\tmuch);

In my personal experience I was confused many times with the synthdef
not found error message in this situations, searching errors in the
synth def when the problem was in the transmission.

Regards
Lucas
