Description
If there is any performance recorded in the copy destination, the
previous material is deleted, replaced by the material being
copied.
If there is any performance recorded in the copy destination, the
copied material is layered over the previously recorded material.
If the sounds in the copied material are different than those at the
destination, the sounds in the copied material change to those
used at the destination.
If there is any performance recorded in the copy destination, the
copied portion is inserted at the destination, without the previous
material being deleted. The song is extended only by the length of
the inserted measures.
