A UGen which pauses and resumes another node. Note that the UGen initially
assumes the node is running, that is, if gate is initially 1, this will
not resume a paused node. Instead, the gate must go to zero and back to
one to resume the node. Additionally, this UGen will only cause action if the
gate value changes, that is, if the node is paused or resumed otherwise, this
UGen will not interfere with that action, unless the gate value is adjusted.
when 0, node is paused, when 1, node is resumed
the id of the node to be paused or resumed
