How to use proxies in array? about howto_co34pt_livecode HOT 4 CLOSED

(
~s0 = Pbind(\instrument,\default,\dur,Pseq([0.5,Pseq([1],inf)],inf),\amp,1);
~s0.play;
~s1 = { Pulse.ar(130, Saw.kr(0.3)) * 0.1 };
~s1.play;
// Then be able to change: 
~s0 = Pbind(\instrument,\default,\dur,Pseq([0.5,Pseq([0.25],inf)],inf),\amp,1);
)

// The initial solution is
p = ProxySpace.push(s.boot);
(
m = Dictionary.new;
m.add(\assign -> { |i, val| switch( i,
    0, { ~s0 = val },
    1, { ~s1 = val },
    2, { ~s2 = val },
    3, { ~s3 = val })
});

m.add(\play -> { |i| switch( i,
    0, { ~s0.play },
    1, { ~s1.play },
    2, { ~s2.play },
    3, { ~s3.play })
});

m.add(\set -> { |i, name, val| switch( i,
    0, { ~s0.set(name, val) },
    1, { ~s1.set(name, val) },
    2, { ~s2.set(name, val) },
    3, { ~s3.set(name, val) })
});
)
// Then..
m[\assign].value(0, { |freq=500, ffreq=120| SinOsc.ar(freq*[1,1.1], SinOsc.ar(ffreq, 0, pi), 0.2) });
m[\play].value(0);
m[\set].value(0, \freq, 400+100.rand2 );

~s[0] = Pbind(\instrument,\default,\amp,0.3);
~s.play;
//add reverb
~s[1] = \filterIn -> {|in| FreeVerb.ar(in,0.6,0.9,0.2)};
//add delay to that
~s[2] = \filterIn -> {|in| CombC.ar(in,0.3,0.2,10)};
//change the wet/dry of `~s[2]` as CombC doesn't pass the original signal
~s.set(\wet2,0.5)

var func;

p = ProxySpace.new(s);

func = { |index| 
    var node = ("s" ++ index).asSymbol; // basically
	p[node] = { Pulse.ar(130, Saw.kr(0.3)) * 0.1 };
