Tempo/Free Memory
Tempo
Tempo is displayed as quarter notes per minute, or beats per minute (bpm). It ranges
from 5 to 9999 bpm, and is adjustable to four decimal places after the whole value.
Programming Tempo Changes
This functionality is described in the Tempo chapter (see “Display and Functions” on
page 447).
Free Memory
Below the Tempo display, you will see the amount of free memory (events) available in
the record buffer. You can increase the amount of free memory by reconfiguring the
memory.
To reconfigure the memory:
1 Double-click on the free memory display.
2 A “Reorganize Memory?” dialog will appear.
3 Confirm by clicking the Reorganize button.
This reorganization is also carried out automatically after saving or loading a song. A
common (and good) use of this feature is to free up memory after closing a song, if
two or more songs were open at the same time.
Time Signature and Division
This is where you can see, and set the time signature of the song. The format is:
Bar numerator—Bar denominator—Division
The division defines the third format value in all position displays (such as in the Event
Edit window), and forms the grid for various length and placement operations. The
division is normally set to 1/16 notes, but has a value range of 1/4 to 1/192 note. If the
note value of the division is equal to or greater than the bar denominator, the third
value of the position display is automatically removed.
Apart from the features described below, you can also use the Global Signature track to
edit time signatures.
