PLcauchy dynamic scope Pcauchy variant 


Part of: miSCellaneous


Inherits from: Pcauchy


Takes Symbol args for later reference by the Streams, which will read from variables in the Environments of their instantiation. See PLx suite.

Creation / Class Methods


*new (mean, spread, length, envir)

Creates a new PLcauchy object.

mean - Symbol or Pcauchy mean arg. Defaults to 0.

If a Symbol is passed, mean can be assigned to an envir variable later on.

Can be dynamically replaced by Patterns or Streams.

spread - Symbol or Pcauchy spread arg. Defaults to 1.

If a Symbol is passed, spread can be assigned to an envir variable later on.

Can be dynamically replaced by Patterns or Streams.

length - Symbol or Pcauchy length arg. Defaults to inf.

If a Symbol is passed, length can be assigned to an envir variable later on.

envir - Dictionary or one of the Symbols

\top, \t (topEnvironment), \current, \c (currentEnvironment).

Dictionary to be taken for variable reference. Defaults to \current.


Examples


(

s = Server.local;

Server.default = s;

s.boot;

)

// definition for future reference in arbitrary Environments,

// Cauchy distribution is not bounded, so do clip !


(

p = Pbind(

\midinote, PLcauchy(\mean, \spread).clip(60, 90),

\dur, 0.1

);

)


// prepare current Environment


(

~mean = 75;

~spread = 0.1;

)



// run


x = p.play;



// move mean value and distribution

// PLseq defaults to repeats = inf


(

~mean = PLseq((80, 79.7..70));

~spread = PLseq([0, 0, 0, 1]);

)


x.stop;
