FINALIZE
The SOUND on SOUND stores overdub files as well as individual origi‐
nal recording material files that were recorded during overdubbing.
Overdub files and original recording material files store only their dis‐
crete, separate recordings (not mix data). The internal clock manage‐
ment data enables you to play back the individual parts from the
corresponding recorded time positions.
