Cause 1: Too many MIDI messages were received all at once, and the DR-880
was unable to process all of them.
Action 1:Reduce the volume of the MIDI messages being sent by the
transmitting device.
Cause 2: You attempted to play back an excessive amount of data, and the DR-
880 was unable to process all of it.
Action 2:Reduce the amount of data being played back, or slow down the
playback tempo.
Checksum error !
Cause: MIDI Exclusive messages could not be received correctly during a
Bulk Load operation.
Action: Try the operation again.
File error !
Cause: During an SMF Import, you attempted to use a file of a type other
than those specified, or one that is invalid.
Action: Use the specified type of file.
Memory full !
Cause: Memory is full.
Action: Save the pattern/song you are creating, and then delete unneeded
patterns or songs.
MIDI off line !
Cause: A MIDI Active Sensing error has occurred. An abnormality has been
detected in the device or cable connected to MIDI IN.
Action: Check the device or cable connected to MIDI IN.
Not supported !
Cause: You attempted to import SMF data that the DR-880 does not support.

Now working...
Cause: Data is being processed.
Action: Please wait until the message disappears.
Now writing...
Cause: Data is being saved to memory.
Action: Never turn off the power while this message is displayed.
* If you turn off the power while this message is displayed, it is possible that
previously saved data (in addition to the data now being written) will also be
lost.
Too busy !
Cause: The system attempted to concurrently process abnormally large
amounts of data, but was unable to succeed.
Action: Make sure that the unit is not being forced to handle an overly large
amount of data (in patterns, or received MIDI messages) all at once,
and try to reduce the amount of data.
Use pattern mode.
Cause: You attempted to use EZ Compose or Groove Modify in Song mode.
Action: Switch to Pattern mode before using EZ Compose or Groove Modify.
User data is damaged.
Factory Reset
Cause: The data in the DR-880’s internal memory is damaged. (This message
will appear when you turn on the power.)
Action: Press [ENTER] to reset the DR-880 to the factory-set condition.
System error !
Cause: An unknown error has occurred in the system.
Action: Immediately stop using the unit, and consult your dealer or nearest
