Preserve Tempo after Selection If selected, the
previous tempo setting that was in effect at the
selection end point is preserved after the selec-
tion. If unselected, the last tempo event created
by the tempo operation continues to the end of
the session, or until the next tempo event be-
yond the selected range.
Scale
The Scale page lets you scale tempos within the
selection by a percentage amount.

Scale page (Advanced Option)
Advanced When the Advanced checkbox is se-
lected, the selection range changes to the Main
Time Scale format, and additional and modified
options become available.
Calculate (Advanced Option) In combination
with settings chosen in the Scale pop-up menu,
the Calculate pop-up menu lets you choose to
calculate the selection end time, the average
tempo, the start tempo, or the end tempo.
Scale (Advanced Option) In combination with
settings chosen in the Calculate pop-up menu,
the Scale pop-up menu lets you choose to scale
all tempos, the start tempo, or the end tempo.
Scaling all tempos scales each tempo in the se-
lected range equally. Scaling the start tempo
scales the tempos unevenly, scaling the first
tempo event the most, scaling each consecutive
tempo event less until the end tempo which is
not scaled. Scaling the end tempo scales the
tempos unevenly, scaling the last tempo the
most, scaling each previous tempo event less
until the start tempo which is not scaled.
Selection Start and End Displays the start and
end points for the tempo operation in the cur-
rently selected Main timebase. When an Edit se-
lection is made, the Start and End fields will dis-
play the selection boundaries. Changing start or
end values changes the selection range.
Start and End Time Displays the absolute time
for the selection start and end points. When the
Main Time Scale is set to Bars|Beats, times are
displayed in the Sub Time Scale. When the Main
Time Scale is set to any absolute timebase, times
are calculated and displayed in Bars|Beats.
Average Tempo Displays the Average Tempo, in
beats per minute (BPM), across the selected
range. Changing the Average Tempo changes
the Scale percentage.
