6.6 To Save or Open a Card File
Your entire “workspace” can be saved to a card file (*.CRD2) so that you can easily
maintain multiple cards. Click on File in the menu bar at the top of the window, and then
either Open, Save, or Save As as is typically used in most Windows applications.
6.7 Notes on Interrupting and Restoring Audio Tracks
If a new audio track is selected (either manually or via any trigger) while another track is
playing, the DMP-200 can resume playing the interrupted track after the new one finishes.
This will only occur, however, for the most recently interrupted track. Any previously
interrupted tracks will not resume, and must be manually restarted if desired.
An interrupted audio track will resume if the attribute “Resume or Cancel” is set
accordingly. See page 16 for a description of this attribute.
For example, consider the following:
1) “Song #5” is selected manually, and starts playing.
2) Halfway through “Song #5”, an external trigger selects “Speech #1”.
3) “Song #5” will fade down, “Speech #1” will play to completion and “Song #5” will
fade back up, restarting at the point where it was interrupted.
In most cases, this behavior is desirable in that it prevents previously-selected tracks from
“mysteriously” restarting. The one notable exception, however, is background music.
If a music track or music list is selected with the intention of providing continuous
background music, it will appear to “fail” if two consecutive interrupts occur. As described
above, after the second interrupting track finishes the first interrupting track will be
restored. When that track finishes, however, the DMP-200 goes silent!
To avoid this situation, consider using the attribute called “Play Automatically at Power-up
or When Idle”. If this attribute is assigned to a Music Track, a Music List, or “Continuous
Mix”, the selection will be made whenever the DMP-200 is idle.
For example, assume that “Continuous Mix” has been set to “Play Automatically at Power-
up or When Idle”. Here is what will happen:
1) At power-up, a music track is randomly selected. Let’s say “Song #8” begins to
play.
2) A discrete trigger selects “Speech #14”. The music fades down, “Speech #14”
plays to completion, and “Song #8” resumes where it left off (this is because
“Song #8” is the most recently interrupted track).
3) Halfway through playback of “Speech #2”, another trigger interrupts it with
“Speech #29”.
4) After completion of “Speech #29”, playback of “Speech #2” will resume where it
left off.
