ComposeSiren

ComposeSiren is a suite of audio and MIDI plugins that synthesize sounds of sirens made by Mécanique Vivante. They also provide automatable parameters from DAW hosts synchronized to MIDI input and output. Theys allow to compose pieces for Mécanique Vivante's siren orchestra in studio by simulating them in real-time. The DAW projects can ultimately be reused to play the pieces on the orchestra during live performances by controlling the sirens from the DAW's MIDI output.

The orchestra is composed of seven MIDI siren instruments :

• two altos (called S1 and S2),
• a bass (called S3),
• a tenor (called S4),
• two sopranos (called S5 and S6),
• a piccolo (called S7).

There are actually two plugins:

• OneSiren, a simple plugin with flexible MIDI routing parameters that can simulate any siren from the orchestra.
• SirenOrchestra, a plugin that simulates the whole orchestra with its original fixed MIDI routing, and provides additional controls such as panning and volume adjustment for each simulated siren, as well as an embedded reverberation module and a master volume control.

Both are currently available in two formats: VST3 and Audio Unit, and also exist as standalone applications.

Development

The ComposeSiren suite is developed on top of the JUCE frameworks. You can find more infos about it there: http://www.juce.com.

The plugins are built on macOS as 64-bit VST3 and Audio Unit formats, and currently tested on [Reaper][6] and Ableton Live. Upcoming windows versions are currently in the development pipeline.

Using the plugins

Download the latest installer for your OS from the [releases page][link] and run it. This will install the VST3 versions of both plugins (as well as their Audio Unit versions on MacOS), and the corresponding standalone applications.

Building with CMake

dependencies

linux

sudo apt-get install libx11-dev libxrandr-dev libxinerama-dev libxcursor-dev libfreetype-dev

Raspberry Pi

sudo apt install cmake libxrandr-dev libxinerama-dev libxcursor-dev libfreetype6-dev libasound2-dev

git tips

• first clone the repository with the --recursive option to fetch JUCE submodule, or run git submodule update --init after cloning.
• if at some point the Dependencies/JUCE submodule is altered by some IDE, you can reset it using git submodule deinit -f . then git submodule update --init

At the moment the plugin is built :

• on Mac OS 11.6.4 using Ninja (Xcode works too)
  • cmake -B build -G Ninja -C Config.cmake -DCMAKE_BUILD_TYPE=Release to setup the build system
  • cmake --build build --config Release to build the plugins and generate the installer
• on Windows 10 using Visual Studio (couldn't get Ninja to work on windows yet)
  • cmake -B build -G "Visual Studio 17 2022" -C Config.cmake
  • cmake --build build --config Release
  • cpack --config build/CPackConfig.cmake
• on Linux or Raspberry
  • cmake -B builds/linux -G "Unix Makefiles"
  • cmake --build builds/linux --config Release
  • no instruction for installer for now

The resulting installer (built with productbuild on mac and NSIS on windows) is created in build/Packaging/ComposeSiren_Installer_artefacts
