We'd prefer if the conditions were defined strictly in terms of  
playbackState.

Suggested phrasing for noteOn: "If playbackState is not UNSCHEDULED_STATE,  
then the user agent must throw an InvalidStateError exception. Set  
playbackState to SCHEDULED_STATE."

Suggested phrasing for noteOff: "If playbackState is UNSCHEDULED_STATE,  
then the user agent must throw an InvalidStateError exception." followed  
by the steps to schedule a playback stop.

As you can tell, we don't think there's any point in disallowing multiple  
calls to noteOff. If we want to disallow it, a new playbackState will be  
needed. One can of course implement a hidden state, but it seems simpler  
and better to make readyState match reality.
