MIDI : Score Editor : Meter Changes

Meter Changes
You can add, edit, and delete Meters in your score. Meter changes affect the number of bars in the score (and in your session). When changing meter, notes are not moved, but the barlines will be redrawn.

You can also add and delete Meters in the Meter ruler in the Edit window and in MIDI Editor windows.

*   
If you want the inserted meter event to fall cleanly on the first beat of the nearest measure, select the Snap To Bar option.
3 Select a note value for the number of clicks to sound in each measure. For a dotted-note click value, select the dot (.) option in addition to the note value.
*
For some meters, it may be desirable to use a dotted value for the click. For instance, if using a meter of 6/8, a dotted quarter note click (yielding two clicks per measure) is generally more suitable than a straight eighth note click (six clicks per measure).
4 Click OK to insert the new meter.

2 Enter values in the Meter Change dialog and click OK.
