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.

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.
