DJ Operation
The DJ plays tracks belonging to a temporary list of tracks known as “Selected Music” and the track that
is currently playing is known as the “Current Track”. Very logical you say. Tracks can be added to
whatever is present in the selected music list, or the list can be replaced entirely with either a new list or
just a single track. For example, you can select a bird family (artist) and add to or replace the selected
music list with all species in that family; or do the same with the contents of a predefined playlist.
The selected music list survives power off and the track that was playing when the unit was powered off
starts to play when it is powered on again. However, it’s important to realize that although the Selected
Music list can be loaded from a stored playlist, an entire family list, or created on the fly by adding
species one at a time, the list cannot be saved to disk as a named playlist (either on the DJ or when
connected to the computer). Consequently, I create all regularly used lists on the computer and transfer
them to the DJ.
The Selected Music list is accessed by selecting Now Playing f
the Main Menu (DJ Screen 7). Initially, the current contents of
Selected Music are displayed (DJ Screen 8) then after five seco
the currently playing track is displayed (DJ Screen 9).
To get from the currently playing track to another track already in
the Selected Music list, all that is required is to roll the scroll-
select dial which immediately redisplays Selected Music and
allows a new selection to be made.
To add a species from a playlist or family requires returning to the
main menu (see DJ Screens 1-6 on page 9) or hitting the back
button step back through the previous menus. I usually opt for
starting at the main menu which only requires one button press.
To retain the current contents of Selected Music, it pays to be
careful when adding to the list. Refer to DJ Screen 6 on page 9. If
“Play Track” is inadvertently selected instead of the intended
“Add to Selected”, the new track becomes the only track in
Selected Music.
All this may seem a little complicated but it soon becomes second
nature.
