The Scale page in the Tempo Operations window lets you scale tempos within the selection by a percentage amount.
When this option is selected, the selection range changes to the Main Time Scale format, and additional and modified options become available.
In combination with settings chosen in the Scale pop-up menu, the Calculate pop-up menu lets you calculate the selection end time, the average tempo, the start tempo, or the end tempo.
In combination with settings chosen in the Calculate pop-up menu, the Scale pop-up menu lets you scale all tempos, the start tempo, or the end tempo.
Scaling all tempos scales each tempo in the selected 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.
Displays the start and end points for the tempo operation in the currently selected Main timebase. When an Edit selection is made, the Start and End fields will display the selection boundaries. Changing start or end values changes the selection range.
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.
Displays the Average Tempo, in beats per minute (BPM), across the selected range. Changing the Average Tempo changes the Scale percentage.
Displays the percentage by which the tempo is scaled, in beats per minute (BPM), across the selected range. Changing Scale changes Average Tempo.
If selected, the previous tempo setting that was in effect at the selection end point is preserved after the selection. If unselected, the last tempo event created by the tempo operation continues to the end of the session, or until the next tempo event beyond the selected range.
