SONG`JOB`Memory`Status`````````Free=100 F1 F2 F3 F4 F5 F6 F7 F8 CS1 CS2 CS3 CS4 CS5 CS6 CS7 CS8 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 occupied entirely by song data. SONG EDIT MODE / SONG JOB 181
