Hi folks,
I am currently unable to run NHHAll extension plugin UGen.
I am under Ubuntu 22, running SC 3.11.2.
I built the sc3-plugins following the GitHub page..
I basically followed the command,
cd sc3-plugins
mkdir build && cd build
cmake -DSC_PATH=/path/to/sc/ -DCMAKE_BUILD_TYPE=Release -DSUPERNOVA=OFF ..
cmake --build . --config Release
sudo cmake --build . --config Release --target install
Note : I installed SuperCollider from apt install
command.
I took care that the path /path/to/sc
above leads to the source directory github release that corresponds to the same version as the one from the SC installed via apt install
command.
Everything seems to work, I test several extensions, and they all work as expected (Decimator, Tartini, OteyPiano, FFTCrest, …).
Unfortunately, the NHHAll extension does not work. It seems to be correctly indexed into the library, but when executing a bit of code such as
x = {NHHall.ar(SinOsc.ar([330, 440]))}.play;
The consol tow me the following error
-> Synth('temp__4' : 1015)
exception in GraphDef_Recv: UGen 'NHHall' not installed.
*** ERROR: SynthDef temp__4 not found
FAILURE IN SERVER /s_new SynthDef not found
Note : if I execute a code with a stereo signal only,
x = {NHHall.ar(SinOsc.ar(440))}.play;
the consol tells me that
The preceding error dump is for ERROR: NHHall expects a stereo signal, but received a size % array.
which, I guess, means that NHHAll is correctly referenced in the library.
I did some digging, and found that the extension files seem to be in the right location:
In /usr/local/share/SuperCollider/Extensions/SC3plugins/NHUGens
, the directory HelpSource
and the file NHHall.sc
are present.
Most importantly, the file /usr/local/lib/SuperCollider/plugins/NHHall.so
exists as well.
I am a bit short on idea right now. I would greatly appreciate any help or idea.
Here is the full consol log after starting and booting the server. I don’t see any particular issue here.

P.S.: Sc is a wonderful tool. Thank you to all the developers!
Best regards.
