ZmqOut

A (very) experimental supercollider plugin that allows streaming SC data out via ZeroMQ sockets. It provides:

• ZmqOut UGen
• zmqOut plugin command

Example runs:

zmqOut plugin command:

s.sendMsg(\cmd, \zmqOut, \start, 0, "tcp://*:5555");    // start a zmq PUB socket with index 0
s.sendMsg(\cmd, \zmqOut, \streamBuffer, 0, b.bufnum);   // stream b buffer via socket 0
s.sendMsg(\cmd, \zmqOut, \stop, 0);                     // stop the socket

ZmqOut UGen:

(
s.sendMsg(\cmd, \zmqOut, \start, 0, "tcp://*:5555");    // start a zmq PUB socket with index 0

SynthDef(\ZmqOut, {
    Out.ar(0, ZmqOut.ar(SinOsc.ar, 0));                 // stream a Sin signal to socket 0
}).add;
)

t = Synth(\ZmqOut);
t.free;

Windows Build

Requires cmake and Visual Studio C++. 2022 community edition works fine.

Install zeromq static lib via vcpkg

git clone https://github.com/microsoft/vcpkg
.\vcpkg\bootstrap-vcpkg.bat
.\vcpkg\vcpkg.exe install zeromq:x64-windows-static

Optional: In order to build a specific commit, edit vcpkg/ports/zeromq/portfile.cmake to have:

vcpkg_from_github(
    OUT_SOURCE_PATH SOURCE_PATH
    REPO zeromq/libzmq
    REF 8c725093ac4b44a97e6cb64566989ef12b71986c

)

Get supercollider sources.

Then in build folder eg: C:\sc\example-plugins\ZmqPub\build>

cmake -A x64 -DSC_PATH=C:\sc\SuperCollider "-DCMAKE_TOOLCHAIN_FILE=C:\sc\vcpkg\scripts\buildsystems\vcpkg.cmake" -DVCPKG_TARGET_TRIPLET=x64-windows-static ..
cmake --build . --config Release
