[Song11] SONG ERASE MEASURE
You can erase all data within the specified
measures of a track in the current song. The
difference between this operation and a DELETE
operation is that when the measures are erased,
they are effectively turned into empty measures
containing no data. Therefore, the measures after
the erased portion will not be moved.
