A->B Button

This button is used to define a playback segment.
The segment can start and end at any arbitrary
location on the CD, and may span track boundaries.

During normal audio playback, click this button
once to define the start of the segment (at this time
the program mode indicator will flash "a->?").  Click
it a second time to define the end of the segment
(the indicator changes to "a->b").  Playback will
stop and Xmcd will enter Segment Play mode.  You may
click the Play/Pause button to play the defined
segment.  If you want the segment to play repeatedly,
enable the "Repeat" button.

You can define the Segment Play mode start and end
points only if audio playback is in progress, and is
not in paused state.  Also, you cannot enter Segment
Play mode during shuffle playback or if a program
sequence is defined.

Xmcd will remain in Segment Play mode until it is
canceled.  To cancel the Segment Play mode, Click the
A->B button a third time, and xmcd will resume
normal playback mode.

During the "a->?" phase, you may use the previous/next
track, previous/next index, REW/FF, or the keypad to
locate the end point quickly.  If you click the Stop
button, a->? phase will be canceled and xmcd will go
to normal playback mode.  If you define an end point
that is before the start point, that is an error
condition and xmcd will go to normal playback mode.

When playing a segment, you may use the REW/FF or the
keypad window's track warp slider to move around
within the segment.  If you move to a location before
the start of the segment, playback will start at the
start of the segment.  If you move to a location
after the end point, playback will stop.  Using the
previous/next track, previous/next index, or the
keypad to change tracks in Segment play mode will
cancel the Segment Play mode.

Changing discs (using the eject button, the
previous/next disc button, or using the keypad in
disc mode) will cancel the Segment Play mode.
