PLwhite dynamic scope Pwhite variant 


Part of: miSCellaneous


Inherits from: Pwhite


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 PLwhite object.

lo - Symbol or Pwhite 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 Pwhite 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 Pwhite 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 = PLwhite(\lo, \hi);



// prepare current Environment

// PLseq repeats defaults to inf


(

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

~hi = PLseq((62..72));

)



// run


(

x = Pbind(

\midinote, p, 

\dur, 0.1 

).play;

)



// replace, converging bounds, stops when ~lo ends (Pseq default repeats = 1)


(

~lo = Pseq((60..80) ++ (80!5));

~hi = 80;

)
