Normally the D-550 is looking for a handshake command in order to dump or load its exclusive messages. This is not a problem if you are using two D-550's. However, if you need to do a one-way dump or load then you will have to hold down the DATA TRANSFER button during the entire procedure to override the handshake command.
1. Press and hold the DATA TRANSFER button down and use the CURSOR to select either [Bulk Dump] or [Bulk Load].
2. Keep holding the DATA TRANSFER Button and press the ENTER button.
3. Continue holding the DATA TRANSFER Button until "Complete" is displayed.
Note: The D-550 must be set to the same MIDI channel when this information is reloaded.
