[the Carpenter]

I've added a 2 minute long song to my latest map.
It's set up to be cued by a trigger_multiple.
It starts fine & runs for it's duration as well.
The trouble is that, although I've set the reset time
on the trigger to 240 (4 minutes), the wave won't play again.
The sound has a start point & an end point encrypted into it.
It is set to not toggled, start silent & play everywhere.
I should add that there are multiple instances of the entity,
as the play everywhere flag semed to fail at it's purpose.

Any ideas as to what I'm doing wrong ?
