is particularly useful with punch recording since
it gives you time to "catch the beat" before
reaching the punch-in point. To set the pre-roll
amount, type a new value in this field, or drag
the Pre-Roll flag in the Main Timebase ruler.
Post-Roll During playback or record, specifies
the amount that plays after the end of a Time-
line selection. Post-roll is useful in punch re-
cording since playback continues after the
punch-out point so you can check for a smooth
transition to previously recorded material. To
set the post-roll amount, type a new value in
this field, or drag the Post-Roll flag in the Main
Timebase ruler.
Start Specifies the beginning of the play or
record range. You can set the start point by en-
tering a location in this field, or by dragging the
corresponding Timeline Selection or Play Start
Marker in the Main Timebase ruler. For more in-
formation, see "Timeline Selection Markers" on
page 373.
End Specifies the end of the play or record range.
You can set the end point by entering a location
in this field, or by dragging the corresponding
Timeline Selection Marker in the Main Timebase
ruler. For more information, see "Timeline Se-
lection Markers" on page 373.
Length Specifies the length for the play or record
range. You can set the length by entering a loca-
tion in this field, or by selecting a range in any
Timebase ruler.
When the Timeline and Edit selections are
linked, you can make an Edit selection in a
track's playlist to set the play and record
range. See "Linking or Unlinking Timeline
and Edit Selections" on page 473
