You can play a series of sounds by using a playStopped handler to
detect when one sound clip has finished, and then playing the next in
the sequence.
I don't know how seamless this is with musical clips, but it works
fine for me with voice clips.
In my case, the sounds are already in a stack, but I guess the
"import" command could be used to load the clips when you need them.
Or perhaps the "prepare" command would allow you to load the next
clip while the current one is playing.
