Random Playlists
PLY00002.RND is an
example of a Random
Playlist filename.
As an alternative, you
can use the “Shuffle”
command (SH) in an
autoexec playlist to
randomly play all the
files on the media on
power-up.
The entries contained in a playlist file that has the extension .RND will be executed
randomly. The playlist will never stop until a Stop command is issued to the unit.
The AM-4 keeps track of which files have played in the random cycle, and will not
repeat any files until all the files have played, at which time the randomness begins
again.
Example Play List
Note: The playlist
parser automatically
adds the carriage return
after the command, so it
is not included in
commands contained in
the playlist.
i,1PL,6LP,37PL,415PL,5PL,60PL <
The list can be arranged all on the same line, as shown above, or vertically as shown
below.

;You can comment your Play List file by using
6PL ;semicolons. All text after a semicolon is
37PL ;ignored until the end of the line where a
;carriage return is encountered.

The “i” character places the AM-4 Digital Audio Machine into “interruptible” mode,
which means that the unit will respond to discrete Select inputs and serial play
commands by jumping immediately to the next entry in the list. The unit remains in
interruptible mode until a “u” character is encountered, which in this example is
never - the entire list is interruptible.
Next, the unit plays track #1. This track will be interrupted by track #6 if the user
issues a new Play command.
When track #1 is done, the unit loops track #6 continuously until the user issues a
Play command.
Then, track #37 plays. The unit continues straight into track #5 followed by track
#60, at which point the list loops back to the beginning, continuing straight into track
#1.
