*It should be noted here that the event sync method is preferrable
if you want to keep file size to a minimum. The streaming method
does not allow Flash to re-use the small component pieces from the
cache, but rather, it copies the audio data into each frame. In
this example, using the event method thus far would mean about 10
bars of total audio (approximately 20 seconds) to be downloaded
(5 layers x 2 bars each), whereas the streaming method would force
a download of 160 bars (5 layers x 2 bars each x 16 repetitions).
Quite a difference!
Play your movie to hear all of the instruments mixed together.
You have just laid the foundation which will allow you to build
an interactive, dynamic soundtrack.
Once you have your individual instrument tracks accessible in this
way, you can make use of a few simple techniques which will allow
you to really harness the power of sound and music to a level unachievable
with loops or pre-recorded production music.
The primary way to make use of layers is to use Flash's envelope
functionality from the sound instance dialogue box. Envelope simply
means a volume control. Essentially what you will be doing is muting
and unmuting individual tracks to create dynamics.

In the frame properties dialogue box {Modify > Frame},
go to the sound tab for any instrument layer. In the window
which displays the audio waveform, click anywhere in the window.
Flash will add an envelope which you can adjust by grabbing
the box and dragging.
