Re: [sc-users] Pattern question: How to set parameters of generators inside a local pattern scope during runtime and similar like the usage of the class Synth args and .set?

Pbindef ?


Pbindef(\x,
	\freq, 100,
	\dur, 0.2
).play


// replace

Pbindef(\x, \freq, 1000);

Pbindef(\x, \freq, Pexprand(100,1000));

Pbindef(\x).stop;


You might also have a look at miSCellaneous lib's PLx patterns
based on dynamic scope, values are
taken from variables in Environments
where Patterns are made to streams.

So instead of passing different args as default values
you would just play the pattern (make the EventStreamPlayers)
in different environments.

PLx list patterns allow replacements of lists
or list elements with immediate effect.
There is also a general placeholder PL.


(
~fLo = 100;
~fHi = 100;

x = Pbind(
	\freq, PLexprand(\fLo, \fHi),
	\dur, 0.2,
	\amp, 0.1
).play;

)

~fHi = 1000;

x.stop
