Thank you for your quick reply, Mark.
Ahh, I see, so single sounds are best referenced or imported; and more than one sound at a time (for one project I have in mind, there might be three or four sound effects playing at once) you use players on a hidden card and reference them from there, if I've understood you correctly?
Which leads me onto one of my personal newbie tripwires, which I am sure is straightforward to do (or obvious) but still leaves me scratching my head:
I drag a player onto the card, click the source folder icon in the inspector, and all sound files are greyed out. So I open someone else's stack, and there is their player which accepts sounds. The only difference which I can see between the two is that in Tracks in the Inspector, the other person's player Type is called Sound, while mine is called Video. I've tried different things to make my player Type to sound (clicking around), but I'm blowed if I can

(it doesn't tell you in the Rev User Guide that's for sure!)... I'd be grateful for help there please...
