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?


i use PatternProxies for this: http://sccode.org/1-4Rs
no additional class required, just a little hack to get at the pattern inside a running EventStreamPlayer (also due to Jonathan :) btw, i would really like to unhackify that, make it part of the official EventStreamPlayer interface -- wd any dev care to work with me on that?

I have a class named PatternController that does exactly that:


p = PatternController {|f=200, a=0.5|
    Pbind(
        \freq, f,
        \amp, a,
        \dur, Pseq([0.25,0.25,0.5],inf)
    )
};
)
p.play

p.set(\f, Pseq([200,300,400,500],inf))
p.set(\f, 300)
p.set(\a, Pwhite(0.3,0.7,inf))
p.set(\f, Pwhite(100,700,inf))
p.inputs // returns [\f, \a]
