  The interfaces are grouped into the following packages:

  Welcome to the Mellite API documentation.

  The interfaces are grouped into the following packages:

  • de.sciss.synth is the ScalaCollider base package, with things like computation Rate, AddAction, and DoneAction.
  • de.sciss.synth.ugen contains the ScalaCollider UGen documentation
  • de.sciss.lucre.synth is the base package for the transactional layer for ScalaCollider, with things like de.sciss.lucre.synth.Bus, Buffer, Node, and Server.
  • de.sciss.synth.proc is the SoundProcesses base package, with things like Proc, Timeline, Folder, AuralSystem, Scheduler, Transport, and Workspace
  • de.sciss.synth.proc.graph are UGen abstractions added by SoundProcesses, such as ScanIn and ScanOut.
  • de.sciss.mellite.gui is the base package for the Mellite graphical user interface.
  • de.sciss.fscape is the FScape base package
  • de.sciss.fscape.graph contains the FScape UGen documentation
  • de.sciss.fscape.lucre is the base package for the transactional layer for FScape, with things like FScape and additional UGens.

  The Lucre transactional object model:

  • de.sciss.lucre.stm is the base package for transactions, with things like Obj, Txn, Sys, and Cursor
  • de.sciss.lucre.artifact is the base package for file system artifacts, with classes Artifact and ArtifactLocation
  • de.sciss.lucre.expr is the base package for expression types such as IntObj, DoubleObj, etc.

  Other useful packages:

  • de.sciss.synth.io for reading and writing audio files
  • de.sciss.osc for general Open Sound Control interfaces

  The synth package provides some extension methods.

  The synth package provides some extension methods. In particular converting numbers to constant graph elements, operators on graph elements and allowing succinct creation of named controls. Furthermore, it contains the play function to quickly test graph functions.

•  object Mix extends Serializable

  A graph element that mixes the channels of a signal together.

  A graph element that mixes the channels of a signal together. It works like the sclang counterpart.

  The Mix companion object contains various useful mixing idioms:

  - Mix.tabulate(n: Int)(fun: Int => GE): corresponds to Seq.tabulate and to Array.fill in sclang. - Mix.fill(n: Int)(thunk: => GE): corresponds to Seq.fill. - Mix.seq(elems: GE*): A shortcut for Mix(GESeq(elems: _*)).

  A separate graph element is Mix.mono. Mix.mono(elem: GE) flattens all channels of the input element before summing them, guaranteeing that the result is monophonic.

  Finally, Mix.fold is an idiom that not actually adds elements, but recursively folds them. Thus, Mix.fold(elem: GE, n: Int)(fun: GE => GE) is equivalent to

  (1 to n).foldLeft(elem) { (res, _) => fun(res) }

  Mix.fold is often used in the SuperCollider examples to apply a filtering process such as reverberation several times. For cases where the iteration index is needed, the full form as shown above can be used instead.

  Examples

  // non-nested multi-channel signal reduced to mono (1)
  play {
    Mix(SinOsc.ar(440 :: 660 :: Nil)) * 0.2 // --> SinOsc.ar(440) + SinOsc.ar(660)
  }

  // non-nested multi-channel signal reduced to mono (2)
  play {
    Mix(Pan2.ar(SinOsc.ar)) * 0.2 // --> left + right
  }

  // mix inner channels
  play {
    // --> [left(440) + left(660), right(440) + right(660)]
    Mix(Pan2.ar(SinOsc.ar(440 :: 660 :: Nil))) * 0.2
  }

  // enforce monophonic mix
  play {
    // --> left(440) + left(660) + right(440) + right(660)
    Mix.mono(Pan2.ar(SinOsc.ar(440 :: 660 :: Nil))) * 0.2
  }

  // combine Mix(), Mix.fill(), Mix.fold()
  // from original SC examples: reverberated sine percussion
  play {
    val d = 6    // number of percolators
    val c = 5    // number of comb delays
    val a = 4    // number of allpass delays
  
    // sine percolation sound :
    val s = Mix.fill(d) { Resonz.ar(Dust.ar(2.0 / d) * 50, Rand(200, 3200), 0.003) }
  
    // reverb pre-delay time :
    val z = DelayN.ar(s, 0.048)
  
    // 'c' length modulated comb delays in parallel :
    val y = Mix(CombL.ar(z, 0.1, LFNoise1.kr(Seq.fill(c)(Rand(0, 0.1))).madd(0.04, 0.05), 15))
  
    // chain of 'a' allpass delays on each of two channels (2 times 'a' total) :
    val x = Mix.fold(y, a) { in =>
      AllpassN.ar(in, 0.050, Seq(Rand(0, 0.050), Rand(0, 0.050)), 1)
    }
  
    // add original sound to reverb and play it :
    s + 0.2 * x
  }

  // Mix.tabulate usage
  // from original SC examples: harmonic swimming
  play {
    val f = 50       // fundamental frequency
    val p = 20       // number of partials per channel
    val offset = Line.kr(0, -0.02, 60, doneAction = freeSelf) // causes sound to separate and fade
    Mix.tabulate(p) { i =>
      FSinOsc.ar(f * (i+1)) * // freq of partial
        LFNoise1.kr(Seq(Rand(2, 10), Rand(2, 10)))  // amplitude rate
        .madd(
          0.02,     // amplitude scale
          offset    // amplitude offset
        ).max(0)    // clip negative amplitudes to zero
    }
  }
