Part of: miSCellaneous


Inherits from: Pgeom

Creation / Class Methods


*new (start, grow, length, envir)

Creates a new PLgeom object.

start - Symbol or Pgeom start arg. Defaults to 0.

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

grow - Symbol or Pgeom grow arg. Defaults to 1.

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

Can be dynamically replaced by Patterns or Streams.

length - Symbol or Pgeom 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 = Pbind(

\freq, Pn(PLgeom(\start, \grow, 50)) % 2000 + 400,

\dur, 0.1

);

)


// prepare current Environment


(

~start = 100;

~grow = 1.1;

)



// from ascending to random


x = p.play;



// replace


~grow = 0.99;


~grow = 1.4;



x.stop;
