Quoting @timblechmann at supercollider/supercollider#782:

many plugins don't perform null pointer checks to ensure that rt memory allocation actually succeeds. instead of a nice error message, the effect is usually a server crash

We may need a few people to split the work up of identifying these UGens (I'll volunteer to be one!). This actually is important work: server crash under high memory use is no good.

This has been an issue for at least a couple of years. I'm logging it now because Tim fixed an issue related to windowing functions in Linux, which I thought might have been related to this problem. It isn't -- I tested against SC's current master, and the PV_PlayBuf / PV_RecordBuf persists.

I'll assign myself temporarily because I want to see if Tim's FFT fix for SC might help these plugins. He replaced some uses of memcpy with memmove. I haven't looked at Josh's code in detail, but it seems entirely possible that memcpy could be in there and maybe it would help to update that. Can't try it just this second. Maybe later today.

If that fails, then I'll reassign to Josh.

I'm building SC3-plugins on OSX 10.9 and I've set supernova=ON.

After running "make install" everything builds fine and in my build folder I get "SC3plugins", as well as "source" folders. While the "source" folder does include both regular and supernova plugins, "SC3plugins" (where everything else is) contains only regular ones.

Also, on my system supernova does not find plugins outside its own plugins folder in the SuperCollider.app/Contents/Resources/plugins, is there maybe connection between that and this bug?

The AmpliduteMod states "As a opposed to Amplitude, AmplitudeMod, allows attack and release times to be modulated once the UGen has been instantiated." it is not true that Amplitude is not modulateable so i think AmplitudeMod is redundant.

Running Ubuntu Studio 14.04, 32-bit. Kernel is 3.16.0-31-lowlatency. Running the most minimal use of OteyPiano causes scsynth to crash with only a message saying RESULT = 0.

Dear SuperCollider team and users,

The supercollider-sc3-plugins source package has recently been accepted to the Debian archive. It compiles to these packages:

• sc3-plugins meta package
• ladspalist
• sc3-plugins-language
• sc3-plugins-server

The package is patched to allow building on all platforms that are supported by Debian's supercollider package.

Now is the time to review and test this package and report problems with it, especially on hardware that isn't x86 or ARM.

I'd also be grateful to hear your opinions on the packaging (e.g. the layout of the packages' contents) from you as a user.

This Debian package will later show up in future releases of Ubuntu's Universe repository and possibly in Raspbian, as well, so there is an incentive to get it right...

The packaging was done as part of an effort to package Sonic Pi, which depends on SuperCollider and the SC3 plugins.

While it is my intention to maintain both the supercollider-sc3-plugins and sonic-pi packages in Debian for the time being, I would welcome at least one more developer willing to help with packaging it correctly for the SC3 plugins users.

Thank you.

(Thanks to Debian developer @petterreinholdtsen for his continuous help on this and to the several SuperCollider developers for accepting packaging related patches and responding to my questions here.)

I was running the server without problems, and suddenly after a server reboot I have this message and the server wont start

*** ERROR: dlopen '/usr/lib/SuperCollider/plugins/StkInst.so' err '/usr/lib/x86_64-linux-gnu/libstk.so.0: undefined symbol: _ZN7RtAudio10openStreamEPNS_16StreamParametersES1_mjPjPFiPvS3_jdjS3_ES3_PNS_13StreamOptionsEPFvN7RtError4TypeERKSsE'

Any clues? libstk was installed from the ubuntu package

see this supercollider mailing list forum issue. Checking out the 3.5 tag version of this file solves the issue

If I try to build sc3-plugins on BeagleBone Black (platform is based on ARM Cortex A8), the cmake fails with:

Call Stack (most recent call first):
  source/StkInst/CMakeLists.txt:50 (TEST_BIG_ENDIAN)


-- Configuring incomplete, errors occurred!

So, this is "caused" by the new StkInst STK wrapper by @sonoro1234. But the eventual cause seems to be that cmake, on this ARM platform, can't successfully complete the TEST_BIG_ENDIAN operation. I've checked the very latest (3.4.1) cmake source code and I don't think their TEST_BIG_ENDIAN has changed to address this, so I think at present we're stuck: the project simply can't build, because it chokes when configuring stk, and there's no option to deactivate it.

If I comment out the test (but since the ARM is little-endian I enable the flag that the test is supposed to decide about) then cmake configures happily.

Possible solutions: detect the arm platform ourselves; or add a flag to turn off building with stk if needed.

System info:

• Linux arm 3.8.13xenomai-bone41 #2 Wed Mar 26 11:41:31 GMT 2014 armv7l GNU/Linux
• cmake version 2.8.11.1

Every time a LADSPA plugin is loaded with the LADSPA UGen, it prints out information like this:

LADSPA: Found plugin 2159 (TAP Chorus/Flanger)
IN 2: Frequency [Hz] [control]
IN 3: L/R Phase Shift [deg] [control]
IN 4: Depth [%] [control]
IN 5: Delay [ms] [control]
IN 6: Contour [Hz] [control]
IN 7: Dry Level [dB] [control]
IN 8: Wet Level [dB] [control]
IN 9: Input_L [audio]
IN 10: Input_R [audio]
OUT 0: Output_L [audio]
OUT 1: Output_R [audio]

This isn't a huge issue when you're just using a LADSPA plugin in an effect synth, but if you're using it in a synth that's triggered very often, it quickly fills up the PostBuffer with this output, sometimes making it very difficult to see much more important information. I think this output should be removed completely, since all of it can be accessed if necessary with the LADSPA.listPlugins method so there's really no need to print it every time a plugin is initialized.

There is an issue with the MdaPiano synth that has been reported to the Overtone project. I think it is an issue for this project to address. See discussion at overtone/overtone#264

Repeating my comment from there...

The MdaPiano code here
https://github.com/supercollider/sc3-plugins/blob/master/source/MdaUGens/MdaUGens.cpp#L119
takes the freq in and converts it immediately to an integer note with
sc_cpsmidi(). Due to how sc_cpsmidi() is written, we are on the
knife's edge of precision issues as people above have found out. If
the input frequency is off by any amount towards zero, the integer
note returned is one lower than desired.

In my opinion, MdaPiano should be changed to allow for some slight
errors in the input frequency and use rounding instead of truncation
after calculating sc_cpsmidi(). Simply adding 0.5f prior to converting to an integer would do this.

The sc_cpsmidi and midicps functions are defined in SuperCollider here
and you can see they involve some magic constants:
https://github.com/supercollider/supercollider/blob/master/include/plugin_interface/SC_InlineUnaryOp.h

Here is a test program to show what is happening with any slight error.

Hi, I know that sc3-plugins are not building at the moment with MSVC, so I thought I would give it a try and see if I can fix that.

I open this issue to track the progress on this.

Hi,

for the Debian package, I have gone through the sc3 plugins tarball and tried to identify all licenses used in it. This is the result:

http://anonscm.debian.org/cgit/pkg-multimedia/supercollider-sc3-plugins.git/tree/debian/copyright

The findings are:

• SuperCollider itself is GPL-3.0+
• the SC3 plugins default license is GPL-2.0+
• some SC3 plugins are GPL-3.0+ in reference to SuperCollider
• most SC3 plugins are GPL-2.0+, possibly in reference to the earlier version of SuperCollider
• some SC3 plugins are LGPL-2.1+
• there are some Boost, BSD and MIT licensed files in there, too.

While none of this is really a problem, I'd humbly suggest to consolidate the licenses to GPL-3.0+ where possible, in accord with SuperCollider itself.

Test case:

{ GaussTrig.ar(1000, 0.3) }.plot(0.01);
{ GaussTrig.kr(1000, 0.3) }.plot(0.01);

Hi ,

I am trying to do plugin profiling with gprof:

I set cmake -DCMAKE_CXX_FLAGS=-pg -DCMAKE_MODULE_LINKER_FLAGS=-pg to get
that
but when I try to run scsynth it gets blocked in the plugin loading phase

Something I am missing?

SuperCollider 3.6.6 on Mac OSX El Capitan 10.11.1

At first I kept getting this error message (displayed here in full).

As soon as I deleted the 'faust_src' folder and it compiled successfully. Hope this helps someone.

Is it safe to remove these conditions? It seems they do nothing:

Ubuntu 14.04. I'm building everything from source -- SC3.8, sc3-plugins at commit e059ac0 (Fri Oct 16, "Merge pull request #40 from sonoro1234/libmodify").

The following code causes supernova to hang, within the first few iterations of the pattern.

(
SynthDef(\freeze, { |gate = 1|
	var sig = BrownNoise.ar(0.05),
	freeze = Rand(0.0, 1.999).trunc(1.0),
	fft = FFT(LocalBuf(256), sig),
	eg = Linen.kr(gate, 0.01, 1, 0.01, doneAction: 2);
	fft = PV_Freeze(fft, freeze);
	sig = IFFT(fft);
	Out.ar(0, (sig * eg).dup);
}).add;
)

p = Pbind(\instrument, \freeze, \dur, 2, \sustain, 1.5).play;

Running supernova within gdb locates one suspicious thread (abbreviated here -- the rest looks normal). I ran several tests in gdb, and whenever it hangs, there is always a thread like this.

Other permutations:

• PV_Freeze vs scysnth - no hang
• PV_MagFreeze vs supernova - no hang

So it's only the combination of PV_Freeze and supernova that is the problem.

I need to use supernova because I'm running a ton of oscillators and parallel processing is cutting DSP time roughly in half. PV_Freeze is the sound I want -- in this case, I like the brutal repetition of grains -- but for the concert in a week and a half, I will have to compromise and use PV_MagFreeze instead, just to be sure the performance doesn't crash and burn.

I might guess that this happens when freeze > 0 in the first calculation block -- but I just tried to come up with an example of that, and then the problem stopped happening. So... I don't know.

The doc of TGrains2 states that the pan parameter should behave like PanAz, but it is not the case. It behaves rather strangely.

b = Buffer.read(Server.default, Platform.resourceDir +/+ "sounds/a11wlk01-44_1.aiff");
x = {TGrains2.ar(
    numChannels: 2,
    trigger: Impulse.kr(10),
    bufnum: b.bufnum,
    rate: 1,
    centerPos: MouseX.kr(0, BufDur.kr(b)),
    pan: MouseX.kr(-1,1.01)
);
}.play;

The sound should be panned fully to the left when pan is at -0.5 and fully to the right when pan is at 0.5. Here, pan behaves more like Pan2, but inverted. Also, the panning goes abruptly from one side to the other when pan goes above 1.00 or below -1.00.

Compare with this:

{PanAz.ar(2, SinOsc.ar(mul:0.1), MouseX.kr(-1.01, 1.01))}.play;

Hi,

Just published a RIR generator of virtual room (image method of Allen an Berkley) plus late reverb modeling by feedback delay networks in:

https://github.com/sonoro1234/DWGReverb

Only source so must be compiled. Script in Lua should be translated (two plugin definitions and a Synthdef) (I someone translates please fork and commit sc file)

I am quite satisfied with sound quality an efficiency.

Take a look and post your comments.

happy holidays for everyone

The BlitB3 uGen is freezing on Windows 10 (64-bit) using the pre-compiled plug-in library and SC 3.7.1 (also 64-bit).

I'm using the following line of code:

{BlitB3.ar(MouseX.kr(0.01, 10000))}.scope

If I move my mouse to the far left of my screen, the uGen will occasionally stop generating. Sometimes, it will start generating again after a few seconds. I did one test where it took about two minutes to start generating again.

Run the following and leave it running for a while:

(
{ JPverb.ar(Saw.ar(100) * EnvGen.kr(Env.perc(0.01, 1), Impulse.kr(0))) * 0.1 }.play;
{ SinOsc.ar(440) * EnvGen.kr(Env.perc(0.01, 1), Impulse.kr(1)) * 0.1!2 }.play;
)

Watch the CPU. For me, it stays at a consistent 7-8% for a while. After about one minute, it spikes to 50% and then quickly drops to less than 1%, and the audio from the other synth sounds weird and crackly.

This happens consistently when audio is fed into a JPverb or a Greyhole followed by a long stretch of complete silence. After the silence, all other audio output from SuperCollider sounds crackly. If audio is played to the reverb unit again, the audio returns to normal after a few seconds.

Even weirder, the crackliness does not seem to show up in Stethoscope, FreqScope, or s.record!

Hello,

Stk is a library devoted to physical modeling

https://ccrma.stanford.edu/software/stk/index.html

As StkUgens are quite buggy I did another stk wraping for myself:
Is is based on StkInstrumnt so that with only one UGen (StkInst) it is
possible to talk to all stk instruments and specific parameter are accesed
by number.

for example stk::Bowed has
https://ccrma.stanford.edu/software/stk/classstk_1_1Bowed.html

Bow Pressure = 2
Bow Position = 4
Vibrato Frequency = 11
Vibrato Gain = 1
Bow Velocity = 100
Frequency = 101
Volume = 128

(
SynthDef(\helpStkbowed,{arg out=0,freq=220,gate=1,amp=1,bowpressure = 64, bowposition = 17, vibfreq=50, vibgain=1, loudness=128;
    var sig,env;
    env = EnvGen.kr(Env.asr(0,1,0.1),gate,doneAction:2);
    sig = StkInst.ar(Stk.at("Bowed"),freq, gate, amp, 0.5,[2,bowpressure,4,bowposition,11,vibfreq,1,vibgain,128,loudness])*env;
    Out.ar(out, sig.dup);

Works for me
but I would like somebody to use it before doing a pull request for sc3-plugins
Also need some advise about copying audio stk files (where, how...)

I'm trying to build this code on Debian Jessie, which ships with Supercollider 3.6.6. I'm getting compilation failures(https://gist.github.com/technomancy/ad2c7081eb9e86d8f8f64ab73cfb6318), but I read that these could be solved by matching up the version of the plugins with the version of Supercollider.

Unfortunately I can't find what version to use since the releases before 3.7.0 were not properly tagged. Can you push tags for these versions or suggest another way to fix the compilation failure?

Please make a provision that giving a control rate signal as an input to the EnvDetect class throws an error.

I did this, and I almost got my ears damaged!!!

Hi,

packaging sc3-plugins for Debian is chugging along.

Now, we need to clarify all licensing issues, hooray!

There is an unclear section in the ATK Readme file:

The filter kernels distributed with the Ambisonic Toolkit are licensed under a Creative Commons Attribution-Share Alike 3.0 Unported License and are copyright the Ambisonic Toolkit Community and Joseph Anderson, 2011.

However, I am not sure how to interpret this, since I did not find filter kernels distributed within the sc3-plugins git tree, only code to read and convert soundfield kernel files in sc/Classes/. Is this a copied boilerplate license from the original ATK that doesn't fully apply to the UGen plugin?

Please advise. Thanks.

The stk source copy that comes with the sc3 plugins is outdated. The tarball contains 4.4.2, last stk release is 4.5.0 more than a year ago.

Hi there.

The sc3 plugins are being used by Sonic Pi, thanks guys.

m = [
  chord(:A3, :minor),
  chord(:F3, :major),
  chord(:C3, :major),
  chord(:G3, :major)
].ring

live_loop :chords do
  c = m.tick
  use_synth :beep
  play_pattern_timed c, 0.125, release: 0.5
  use_synth :piano
  play_pattern_timed c, 0.125, release: 1
  sleep 1-6*0.125
end

The current sc3 plugins v3.7.0-alpha1 release contains a piano that is out of tune. Here is an example audio file.

When using the current version in git, it's ok, example audio file.

Since a few people are self-compiling the sc3 plugins for their system, it would be beneficial if you could push a 3.7.0-alpha2 release. Thanks!

Hello,

there is an effort to package sc3-plugins for Debian, Raspbian and Ubuntu going on.

We have few open questions regarding the packaging choices and would love to hear your opinions.

Thanks!

Hi,

the DEINDUGens has a minor licensing issue. The original code is

// author: "Julian Parker"
// license: "none"
// copyright: "(c) Julian Parker 2013"

yet the faust code generator (?) added a GPL-2+ license to it.

I suspect that this is also what Julian wanted, but just to clarify and to appease the licensing demons at Debian, it would be helpful if the license-entry could be clarified to be GPL-2+.

It seems for a lot of the extensions the documentation is not categorized according to the hierarchy set up by the base SC distribution.

For example, a lot of the base distribution generator UGens are in UGens > Generators, eg: UGens > Generators > PhysicalModels.

However a whole bunch of the extensions place their help files into UGens > PhysicalModels. This makes it harder to browse the help system when looking for UGens in a particular class, or other UGens similar to one the user already knows. I feel like they should be consolidated in to either location.

I'm trying to install this on Arch Linux. I have SC 3.7.1 installed from git (supercollider-git). But when I try to install the plugins I get the following error (truncated).

[ 17%] Building CXX object source/CMakeFiles/OteyPianoUGens_supernova.dir/OteyPianoUGens/OteyPiano.cpp.o In file included from /tmp/pacaurtmp-dabrowsa/sc3-plugins-git/src/sc3-plugins/source/OteyPianoUGens/dwgs.h:8:0, from /tmp/pacaurtmp-dabrowsa/sc3-plugins-git/src/sc3-plugins/source/OteyPianoUGens/piano.h:8, from /tmp/pacaurtmp-dabrowsa/sc3-plugins-git/src/sc3-plugins/source/OteyPianoUGens/OteyPiano.cpp:7: /tmp/pacaurtmp-dabrowsa/sc3-plugins-git/src/sc3-plugins/source/OteyPianoUGens/../DWGUGens/dwglib/DWG.hpp: In member function ‘void TUBE::set_area(float, float)’: /tmp/pacaurtmp-dabrowsa/sc3-plugins-git/src/sc3-plugins/source/OteyPianoUGens/../DWGUGens/dwglib/DWG.hpp:1271:53: error: no matching function for call to ‘min(float, double)’ loss = 1.0 - std::min(lossF/sqrt(a1),1.0);

The source fail to build in Debian after Debian switched to GCC 6 as the default C++ compiler. See https://bugs.debian.org/831078 for details.

The problem is that this expression no longer work in source/DWGUGens/dwglib/DWG.hpp:

float loss;
...
void set_area(float a1,float lossF)
    {
        if(a1 < 1e-18)
            loss = 0.0;
        else
            loss = 1.0 - std::min(lossF/sqrt(static_cast<double>(a1)),1.0);

    }

I believe the cause is that the compiler now pick the function float sqrt(float) instead of the function double sqrt(double). There are two ways to solve the build problem, and I am unsure which one is the best. Either replace 1.0 with 1.0f to use float everywhere in the calculations, or cast a1 using static_cast(double>(a1) to tell the compiler to use doubles everywhere. I assume the former calculation is slightly quicker, while the latter is more accurate.

Do you have an opinion on how this should be solved? How important is the accuracy of the calculation?

LADSPA.listPlugins is supposed to print out all the plug-ins that are installed, with their inputs and outputs. A custom binary, ladspalist, is supposed to handle this, but it seems to choke on some plug-ins. When I boot the server, I see "Found 140 LADSPA plugins" but LADSPA.listPlugins shows only two:

I made a debug build and ran it in gdb. This tells me that TAP Reflector[1] is the problem, and there's a bad pointer.

Ubuntu 12.04, TAP plugins come from the standard package repository (v. 0.7.1-2fakesync1).

[1] http://tap-plugins.sourceforge.net/ladspa/reflector.html

compare:

{GVerb.ar(Dust.ar(5), SinOsc.kr(0.3, 0.5pi).range(10, 14), drylevel:0)}.play

{GVerb.ar(Dust.ar(5), SinOsc.kr(0.3).range(10, 14), drylevel:0)}.play

The second has a major glitch, while the first is perfectly smooth.
