I'm not sure what you mean by "how to set the arguments to a playing 
routine/task." Routines and tasks don't really have arguments.

If I may hazard a guess, it sounds very close to the central problem 
that has animated my coding efforts for the last year and a half. That 
is, how to create processes you can change from outside while playing 
them. The environment solution is very much in the right direction. I 
found that it's risky to keep loose associations of environment 
variables and tasks or patterns--also, the risk increases the more 
complex the processes become. So I built a container structure so I can 
write a prototype that defines all the environment variables that are 
needed along with defaults, and then you can make as many instances of 
that prototype as you need.

AdhocClass({
	~timeisme = 100;
		// processes in my system have to be event patterns,
		// so a Task should be written as Proutine instead
	~asPattern = {
		Proutine({
			loop {
				~timeisme.value.postln;
				(play:0, delta:0.2).yield;
			}
		});
	};
}) => PR(\timeisme);

PR(\timeisme) => BP(\time1);
PR(\timeisme) => BP(\time2);

BP(\time1).play;
BP(\time1).v.timeisme = 200;
BP(\time1).stop;

Now you have two separate environments, each with its own ~timeisme 
variable that can be changed independently. I don't have to worry about 
naming conflicts, and I don't have to worry about forgetting to 
initialize the variables in performance (assuming I tested the 
prototype thoroughly!).

There are lots of other goodies in there too. One of my projects over 
the next few months is to document it so that maybe it will make sense 
to someone other than myself :)
