Example Play List
i,1,L6,37,w,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.
i
1 ;You can comment your Play List file by using
L6 ;semicolons. All text after a semicolon is
37 ;ignored until the end of the line where a
w ;carriage return is encountered.

The “i” character places the 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.
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, in
which case it plays track #1 on the internal hard drive (when installed). 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. When the track is complete, the “w” causes the Digital Audio
Machine to wait for another Resume input or Play command.
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.

The order of power up
execution allows the
Digital Audio Machine
to use the removable
drive to update itself,
either temporarily or
permanently.
When power is first applied to the Digital Audio Machine, it flashes the front panel
LED green while performing a self test. It then checks to see if a track or Play List
should be played, according to the following priority:
• If the test button is depressed, process command file COMMAND0.BAT on the
removable media.
• Play any track or Play List that is hardwired at the Control Connector.
• Play track or Play List number 0 from the removable drive.
• Play track or Play List 0 from the internal drive.
