[sc-users] Re: sending messages from SERVER to SCLANG

[Daniel Peterson]

In the helpfile it shows you how to do this.  You use SendTrig.kr  So  
just put your amplitude data in the 3rd argument for SendTrig:

something like this...

SynthDef(\trigs, {arg inbus, id;
	var trig, amp, in;
	in = In.ar(inbus);
	amp = Amplitude.kr(in);
	trig = Trig1.ar(Impulse.ar(0.05)); // trigger
	SendTrig.ar(trig, id, amp); // send the current amplitude back to  
the lang
	}).load(s);

then access it in the lang like this....

OSCresponderNode(s.addr, '/tr', {arg time, resp, msg;
		var id, amp;
		id = msg[2];
		// check if this is the correct trigger
		(id == proc.group).if({
		amp = msg[3].postln;
	}))


I don't know what you want to do with it...

the msg arg in the OSCresponder node will be an array of 3 values  
that are sent by the SendTrig,  so msg[3] will be you amplitude data  
and msg[2] will be the trigger's id to make sure you are talking to  
the correct trigger.

Hope this makes sense.
