Use direct event handling.

The Sound Stage is a room. "You can hear two songs alternating in the background."

Sound 1 is the file "song1.ogg".
Sound 2 is the file "song2.ogg".

When play begins:
	unless glk sound notification is supported:
		say "This interpreter does not support sound notifications! Song alternation won't work!";
	play Sound 1 with notification.

To play (SFX - sound name) with notification:
	(- glk_schannel_play_ext(gg_foregroundchan, ResourceIDsOfSounds-->{SFX},1,1); -).

Glulx input handling rule for a sound-notify-event:
	let sound id be glk event value 1;
	if sound id is the Glulx resource ID of Sound 1:
		play Sound 2 with notification;
	otherwise:
		play Sound 1 with notification.
