Recording to the instrument's internal memory
The total capacity of the instrument's internal recorder memory is approximately 90,000 notes.
 For reference, a 5000 note recorder capacity would be sufficient to record the Beethoven piece 'Für Elise' approximately 3~4 times, which is the
equivalent of 10~15 minutes or recording.
However, the total recording time will change depending on the number of notes played and the tempo of the piece. In addition, pedal presses will
also influence the maximum recording length, with each pedal press the equivalent of one note.
If the maximum recording capacity is reached during recording, the recorder will stop automatically. The performance will be recorded
until the recorder is stopped.
Performances recorded to the instrument's internal memory will remain after the power is turned off.
The Recorder will capture sound changes during recording.
The recorder will capture switching to Dual or Split playing mode.
The Recorder will not capture changes to effect settings made during the recording. If an Effect is selected, it will be continuously
applied to the sound during recording.
The Recorder will not capture changes to the Metronome tempo settings made during the recording. Performances will be recorded
at the tempo specified immediately before recording.
