[chuck-users] ADSR modulation question

Remember that when you spork a shred that operation returns a Shred  
and you can get the int of that with Shred.id(). You can store that  
int in an intermediate variable that you can access with a name. You  
can't access that name directly from the command line but you could  
store those names in an object and have a little script that you can  
launch that polls your objects (public ones that can be seen outside  
of the scope of their shred) and prints out the shred ids you are  
looking for. Not totally elegant but effective.

For your other problem with modularity of code I solve that with the  
object structure. You can make a synth public object and then load it  
into a running VM. Then you can load separate score files that have  
your synth object in there. I regularly do things like this:

%>chuck mysynth.ck score1.ck
%> score2.ck  (where score 2 also uses the mysynth object in mysynth.ck)

Also, with ADSR can you poll its output? I thought that would have to  
do something like this:

step s => ADSR env => blackhole;
1. => s.value;

Doesn't ADSR multiply its input with its current value?

Best of luck. Thanks for the multitude of questions.
