3: MEMORY STATUS
Indicates the amount of memory available for song recording.
This job is not available when the rhythm track (track 9) is selected. The
"CLEAR RHYTHM TRACK" job described on page 182 appears in its place.
A display of "Free=80%", for example, means that approximately 20% of
the available memory has been used, and approximately 80% is available for
further recording.
A "Memory full" error message may appear during recording even if this
function does not indicate "Free=0%". This is because a certain amount of free
"work area" is required by each function, and the memory can never be occu-
pied entirely by song data.
