building

SoundProcesses builds with sbt against Scala 2.12, 2.13, Dotty (JVM), and Scala 2.13 (JS). The last version to support Scala 2.11 was 3.31.0. The dependencies should be downloaded automatically from Maven Central repository.

The Scala.js support it is still in experimental stage. Linker errors and bugs are to be expected here.

linking

The following submodules are available:

"de.sciss" %% "lucre-synth"             % v  // transactional layer for ScalaCollider
"de.sciss" %% "soundprocesses-core"     % v  // everything but views and compiler
"de.sciss" %% "soundprocesses-views"    % v  // common swing views
"de.sciss" %% "soundprocesses-compiler" % v  // compiler integration

The current version v is "4.14.2".

usage

Project is still sparse, however there is a graphical front-end Mellite, and the Mellite website contains tutorials on SoundProcesses.

notes

• currently, constant Expr object do carry an id and thus are not identical to each other when created repeatedly even with the same peer constant. This was done in order to satisfy Obj property, e.g. for any IntObj including its constants. A future version may go back to 'cheap' constants which must be explicitly lifted if one wants to access attr on them.

Scala.js

The following abstractions are currently not supported

• Bounce
• (Ex) Sys.Process, Sys.Exit, AudioFileSpec.Read
