I've read up on sound channels and all my music is played using channels.
Now my game takes place in a small area (a lot of rooms but a small area all things considered). So changing music in different rooms wouldn't really make sense. Is there a way to cycle 3 or 4 different background tunes as background music? For now, I solved this using a single track with spliced together music. But then I have to make a new file every time I want to change one track. It would be easier to just replace a track in AGS and let AGS do the rest.
