Transferring Patches To and From the D-50/550
You can use MIDI to transmit patch data (64 patches) saved on 
your D-50 and receive the data with the D-05. This procedure is 
known as “bulk load.” This is an easy and convenient way to take 
your own original patches (64 patches) created with the D-50 and 
use them with the D-05.
Conversely, you can also send patch data edited using the D-05 
via MIDI to the D-50/550. This procedure is called “bulk dump.”

Data transfer
A set of data can be sent to another D-50 using Roland MIDI 
exclusive messages, and stored on that device. This is called “data 
transfer”; transmitting data is called “bulk dump,” and receiving 
this data is called “bulk load.”
Data transfer can occur using either of two methods: handshake 
or one-way.
Handshake data transfer
Handshake transfers the data while verifying that the other 
connected device has correctly received the data; this allows the 
data to be sent reliably and quickly.

One-way data transfer
One-way is the method in which data is sent from one unit 
regardless of the state of the receiving unit. Although the 
connection is simple, it takes somewhat longer to transfer the 
data than the handshake transfer method.
