Alcorn McBride MP3 Audio Machine User’s Manual • Rev H • April 2, 2004
Play Lists may contain references to other Play Lists, but as soon as such a reference
is encountered the new Play List begins execution, and the old one is abandoned.
Example Play List
i,1,L6,37,415,5,60 <
The Play List is a list of numbers representing the file numbers of audio tracks. The
list can also contain special control codes or symbols to govern playback. 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
L6
;semicolons. All text after a semicolon is

;carriage return is encountered.

The “i” character places the MP3 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.
Track numbers may be
1, 2 or 3 digits long.
Leading zeroes are
ignored.
Next, the unit plays track #1 on the removable media, unless it cannot find a track #1 there.
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.
