PLbrown dynamic scope Pbrown variant
Part of: miSCellaneous
Inherits from: Pbrown
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, step, length, envir)
Creates a new PLbrown object.
lo - Symbol or Pbrown 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 Pbrown 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.
step - Symbol or Pbrown step arg. Defaults to 0.125.
If a Symbol is passed, step can be assigned to an envir variable later on.
Can be dynamically replaced by Patterns or Streams.
length - Symbol or Pbrown 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 = PLbrown(\lo, \hi, \step);
// prepare current Environment
// PLseq repeats arg defaults to inf
(
~lo = 55;
~hi = 80;
~step = Pstutter(10, PLseq([0.05, 3.5]));
)
// run
(
x = Pbind(
\midinote, Ptuple(p!2),
\dur, 0.1
).play;
)
// replace
(
~lo = Pseq((50..90));
~hi = Pseq((50..90) + 15);
)
