Anytime a gate off message is scheduled in the same control period as 
the s_new, the EnvGen will never see the trigger.
possible solutions:

initialize gate to -1 < gate < 0. Then if EnvGen sees 0 on starting up 
it can assume that the EnvGen has been released by explicitly setting 
it to zero. gate must be > -1 because that is already used for the 
EnvGen voice stealing mode.
	pro: seems like the most minimal change.
	cons: This would break existing patches that wait for a trigger, 
because all patches that start with 0 waiting for a trigger will go 
immediately into a done state. These patches would have to be changed 
to initialize gate < 0 and recompiled. Notationally inconvenient: would 
require explicitly initializing the gate argument of a SynthDef.

have a separate input for start trigger and release trigger.
	cons: breaks all existing patches that use EnvGen. not as simple as a 
single gate. seems inelegant.
