Negatum

statement

Negatum started as a genetic programming experiment for SoundProcesses, and eventually became entangled with the particular sound installation of the same name that was part of the exhibition "Imperfect Reconstruction". Now it is part of SoundProcesses/Mellite, with the original sound installation remaining in a dedicated app project.

requirements / installation

This project builds against Scala 2.13, 2.12 using sbt (the last version to support Scala 2.11 was 0.8.1).

To build the application:

cd app
sbt assembly

Then to run:

java -jar Negatum.jar

project structure

The project is a hybrid between Mellite "extensions" and the original sound piece, with the following sbt modules in place:

• negatum-core: contains the SoundProcesses based objects for genetic programming (Negatum)
• negatum-views: contains the Mellite views for core (e.g. NegatumView)
• negatum-app: (in separate directory app) contains a standalone application with the original sound piece

In the future, more abstractions (SOM, SVM) will be moved to the core module. The dependency structure is now a bit tricky:

• negatum-core depends on SoundProcesses
• negatum-views depends on negatum-core and mellite-core
• mellite (full) depends on negatum-views
• negatum (full) depends on mellite (full)

So when building with locally published artifacts, the build/publish order is:

1. mellite-core
2. negatum-views
3. mellite (full)
4. negatum (full)

linking

To use this project as a library, use the following artifact:

libraryDependencies += "de.sciss" %% "negatum-core"  % v
libraryDependencies += "de.sciss" %% "negatum-views" % v

The current version v is "1.14.1"
