Song Mode
The TRACK Page
Delete
The Delete function is used to remove a region of time from the current song. This function
is different from the erase function because not only does it remove the events from the
selected time, it will delete the entire selected range of time from the song, modifying the
song's End point appropriately (on all tracks). This is similar to cutting a section out of a tape
and splicing the ends.
