What you want is most likely a very short delay line from the second
unit with a reader of that line at the input of the first. I am fairly
certain that the delay has to be at least one audio chunk in length
(even if sc lets you specify a shorter delay, it cannot do a shorter
delay without infinite recursion issues).
Thanks - I've got it working. Code pasted below:
(
{
var b1=Buffer.alloc(s,s.sampleRate/10,1);
var b2=Buffer.alloc(s,s.sampleRate/10,1);
var imp=EnvGen.ar(Env.triangle(0.01,1));
var damping=0.0001;
//var mute=1-EnvGen.ar(Env.linen(0,0.04,0,1,'step'));
var sprGen,s1,s2,op;
var crossRes=250;
sprGen={arg impulse,konst;
var harmPower=1;
var nh=20;
var spr;
spr=Array.fill(nh,{ arg ind; var hAmp;
//ind.postln;
hAmp=1/((ind+1)**harmPower);
//hAmp.postln;
Spring.ar(impulse*hAmp,konst*(ind+1),damping);
});
Mix.new(spr);
};
//op=OutputProxy('ar',Silence.ar());
s1=sprGen.value(imp+PlayBuf.ar(1,b2,1,0,0,1),50);
RecordBuf.ar(s1/crossRes,b1,1,1,0,1,1);
s2=sprGen.value(PlayBuf.ar(1,b1,1,0,0,1),75);
RecordBuf.ar(s2/crossRes,b2,1,1,0,1,1);
Mix.new([s1,s2]);
}.play;
);
