Package eu.bandm.music.applications.feldproj

Class Generate_1

java.lang.Object
eu.bandm.music.applications.feldproj.Generate_1
public class Generate_1 extends Object
Generate a Feldman-type score according to the control value curves given in a tscore object. The generated voices have the same name as the input voices. The input events are pairs of a lower and an upper limit. They may only appear at TpTops, which correspond to measure bars in the output voice. Between these values a linear interpolation happens. Whenever an output event shall start, a random value between these interpolated limits decides which kind to generate.

The output events are FeldmanProjection_n events, i.e. aligned to quarters. Input and output voices share the same TpTop line, and TDivisions are inserted for the output whenever nevessary (by Generate_1.Agent.write_to_score().

Usage: Call fromStream(InputStream, String, MessageReceiver,long).

      protected final Map<Event,Integer> minValues
      Interpolated input curve, for every 1/4 time point one value.

    • lastEnd

      int lastEnd

    • measures_per_page

      public static final int measures_per_page

  • Constructor Details

    • Generate_1

      public Generate_1(Part part, MessageReceiver<SimpleMessage<eu.bandm.tools.util.xml.XMLDocumentIdentifier>> msgr)
      Construct an instance for one particular input Part of a tscore input source.

  • Method Details

    • update_topTps

      protected void update_topTps()
      First step of interpreting syntactic to semantic contents: Parse the TpTop text in the input tscore to bar numbers, constructing an ordered sequence of TpTops:

    • update

      public void update()
      Analyses the parsed raw data in inPart and generates an Generate_1.Agent for every input voice.

    • get_tp

      Tp get_tp(int viertel)
      Get a Tp for the time point value given in 1/4 notes.. Create a new TpTop for all multiples of 4, and generate sub-divisions by 4 for the others.

    • get_top

      TpTop get_top(int ganze)
      Get a TpTop for the time point value given in whole notes..

    • fillInterpolations

      void fillInterpolations(Vox voice, Map<Event,Integer> src, Map<Integer,Integer> interpol)
      Translate the input events (per whole notes) into the interpolated curves (per 1/5 note).

    • generate

      @Opt @Opt FeldmanProjection_n generate(long randomSeed)
      Generates the output score. First the input data is checked for completeness and the interpolatons are calculated for each agent. Then the lower three agens and the upper three agents are processed separately: For every time point (measured in 1/4 notes) Generate_1.Agent.generate(int) is called. Then the result object is generated, all agent data is translated to voice data by invokng Generate_1.Agent.write_to_score(). Finally some global "timeless" parameters are stored to the result.

    • fromStream

      @Opt public static @Opt FeldmanProjection_n fromStream(InputStream inputstream, String sourceIndication, MessageReceiver<SimpleMessage<eu.bandm.tools.util.xml.XMLDocumentIdentifier>> msg, long seed)
      Reads the tscore source data for the meta data and returns the synthetic outScore derived from it. This code creats an instance and invokes update() and generate(long). The resulting outScore is taken from outScore.

    • fromFile

      @Opt public static @Opt FeldmanProjection_n fromFile(File inputfile, MessageReceiver<SimpleMessage<eu.bandm.tools.util.xml.XMLDocumentIdentifier>> msg, long seed)
