property pSoundChannel -- sound channel to check
property pWhichFrame -- frame to go to when sound stops

-----------------------------------------------------
-- This behavior keeps the playhead on the same
-- frame while a sound in a specified channel
-- is playing. When the sound stops, the playhead
-- will go to a specified marker.
--
-- Attach this Behavior to a Frame Script.
