Part of: miSCellaneous


Inherits from: Pmeanrand


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 (lo, hi, length, envir)

Creates a new PLmeanrand object.

lo - Symbol or Pmeanrand lo arg. Defaults to 0.

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

Can be dynamically replaced by Patterns or Streams.

hi - Symbol or Pmeanrand hi arg. Defaults to 1.

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

Can be dynamically replaced by Patterns or Streams.

length - Symbol or Pmeanrand 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


p = PLmeanrand(\lo, \hi);



// prepare current Environment

// PLseq repeats arg defaults to inf


(

~lo = PLseq((60, 60.25..70));

~hi = PLseq((70, 69.75..60));

)



// run


(

x = Pbind(

\midinote, Ptuple([p, 65]), 

\amp, [0.1, 0.06], 

\dur, 0.1

).play;

)



// replace


(

~lo = 60.5;

~hi = 61;

)


x.stop;
