Roland Exclusive Messages
1. Data Format for Exclusive Messages
Roland's MIDI implementation uses the following data format for all exclusive messages (type IV):
| Byte | Description |
| F0H | Exclusive status |
| 41H | Manufacturer ID (Roland) |
| DEV | Device ID |
| MDL | Model ID |
| CMD | Command ID |
| [BODY] | Main data |
| F7H | End of exclusive |
MIDI status: F0H, F7H
An exclusive message must be flanked by a pair of status codes, starting with a Manufacturer-ID immediately after FOH (MID version 1.0).
Manufacturer ID: 41H
The Manufacturer-II) identifies the manufacturer of a MIDI instrument that triggers an exclusive message. Value 411 represents Roland's Manufacturer-II.
Device-ID:DEV
The Device-II) contains a unique value that identifies the individual device in the multiple implementation of MIDI instruments. It is usually set to 0011 0FH ,a value smaller by one than that of a basic channel, but value 0011 1F11 may be used for a device with multiple basic channels.
Model-ID:MDL
The Model- ID contains a value that uniquely identifies one model from another. Different models, however, may share an identical Model- ID if they handle similar data.
The Model-II) format may contain 0011 in one or more places to provide an extended data field. The following are examples of valid Model-IDs, each representing a unique model:
0111
021
03H
00H 01H
0011.021
00H.00H.01H
Command-ID:CMD
The Command-ID indicates the function of an exclusive message. The Command-ID format may contain 00H in one or more places to provide an extended data field. The following are examples of valid Command-IDs, each representing a unique function:
011
02H
0311
0011.0111
0011 0211
00H,00H,01H
Main data:BODY
This field contains a message to be exchanged across an interface. The exact data size and contents will vary with the Model-ID and Command-ID.
2. Address-- mapped Data Transfer
Address mapping is a technique for transferring messages conforming to the data format given in Section 1. It assigns a series of memory-resident records--waveform and tone data, switch status, and parameters, for example--to specific locations in a machine-dependent address space, thereby allowing access to data residing at the address a message specifies.
Address-mapped data transfer is therefore independent of models and data categories. This technique allows use of two different transfer procedures: one-way transfer and handshake transfer.
One way transfer procedure (See Section3 for details.)
This procedure is suited for the transfer of a small amount of data. It sends out an exclusive message completely independent of a receiving device status.
Connection Diagram
Connectional point2 is essential for "Request data" procedures, (See Section3.)
Handshake transfer procedure (See Section4 for details.)
This procedure initiates a predetermined transfer sequence (handshaking) across the interface before data transfer takes place. Handshaking ensures that reliability and transfer speed are high enough to handle a large amount of data.
Connection Diagram
Connectionat points1 and 2 is essential.
Notes on the above two procedures
There are separate Command-IDs for different transfer procedures.
DevicesA and B cannot exchange data unless they use the same transfer procedure, share identical Device-ID and Model ID, and are ready for communication.
3. One-way Transfer Procedure
This procedure sends out data all the way until it stops when the messages are so short that answerbacks need not be checked.
For long messages, however, the receiving device must acquire each message in time with the transfer sequence, which inserts intervals of at least 20 milliseconds in between.
Types of Messages
| Message | Command ID |
| Request data 1 | RQ1 (11H) |
| Data set 1 | DT1 (12H) |
# Request data # 1: RQ1 (11H)
This message is sent out when there is a need to acquire data from a device at the other end of the interface. It contains data for the address and size that specify designation and length, respectively, of data required.
On receiving an RQI message, the remote device checks its memory for the data address and size that satisfy the request.
If it finds them and is ready for communication, the device will transmit a "Data set 1 (DT1)" message, which contains the requested data. Otherwise, the device will send out nothing.
| Byte | Description |
| F0H | Exclusive status |
| 41H | Manufacturer ID (Roland) |
| DEV | Device ID |
| MDL | Model ID |
| 11H | Command ID |
| aaH | Address MSB |
| LSB | |
| sGH | Size MSB |
| LSB | |
| sum | Check sum |
| F7H | End of exclusive |
The size of the requested data does not indicate the number of bytes that will make up a DT1 message, but represents the address fields where the requested data resides.
Some models are subject to limitations in data format used for a single transaction. Requested data, for example, may have a limit in length or must be divided into predetermined address fields before it is exchanged across the interface.
The same number of bytes comprises address and size data, which, however, vary with the Model-ID.
The error checking process uses a checksum that provides a bit pattern where the least significant 7 bits are zero when values for an address, size, and that checksum are summed.
Data set 1:DT1(12H)
This message corresponds to the actual data transfer process, Because every byte in the data is assigned a unique address, a DT1 message can convey the starting address of one or more data as well as a series of data formatted in an address dependent order.
The MIDI standards inhibit non-real time messages from interrupting an exclusive one. This fact is inconvenient for the devices that support a "soft-through" mechanism. To maintain compatibility with such devices, Roland has limited the DT1 to 256 bytes so that an excessively long message is sent out in separate segments.

*A DT1 message is capable of providing only the valid data among those specified by an RQ1 message.

Example of Message Transactions
Device A sending data to Device B Transfer of a DT1 message is all that takes place.
Device B requesting data from Device A
Device B sends an RQI message to Device A. Checking the message, Device A sends a DT1 message back to Device B.
4. Handshake- Transfer Procedure
Ilandshaking is an interactive process where two devices exchange error checking signals before a message transaction takes place, thereby increasing data reliability. Unlike one-way transfer that inserts a pause between message transactions, handshake transfer allows much speedier transactions because data transfer starts once the receiving device returns a ready signal.
When it comes to handling large amounts of data-- sampler waveforms and synthesizer tones over the entire range, for example-- across a MIDI interface, handshaking transfer is more efficient than one-way transfer.
Types of Messages

| Want to send data | WSD (40H) |
| Request data | ROD (41H) |

Want to send data: WSD (40H)
This message is sent out when data must be sent to a device at the other end of the interface. It contains data for the address and size that specify designation and length, respectively, of the data to be sent.
On receiving a WSI) message, the remote device checks its memory for the specified data address and size which will satisfy the request. If it finds them and is ready for communication, the device will return an "Acknowledge (ACK)" message.
Otherwise, it will return a "Rejection (RJC)" message.

- The size of the data to be sent does not indicate the number of bytes that make up a "Data set (DAT)" message, but represents the address fields where the data should reside.
Some models are subject to limitations in data format used for a single transaction. Requested data, for example, may have a limit in length or must be divided into predetermined address fields before it is exchanged across the interface.
The same number of bytes comprises address and size data, which, however, vary with the Model-Ib.
*The error checking process uses a checksum that provides a bit pattern where the least significant 7 bits are zero when values for an address, size, and that checksum are summed.
Request data: RQD (41H)
This message is sent out when there is a need to acquire data from a device at the other end of the interface. It contains data for the address and size that specify designation and length, respectively, of data required.
On receiving an RQD message, the remote device checks its memory for the data address and size which satisfy the request. If it finds them and is ready for communication, the device will transmit a "Data set (DAT)" message, which contains the requested data. Otherwise, it will return a "Rejection (RJC)" message.

Acknowledgement: ACK (43H)
This message is sent out when no error was detected on reception of a WSD, DAT, "End of data (FOD)", or some other message and a requested setup or action is complete. Unless it receives an ACK message, the device at the other end will not proceed to the next operation.

Communications error: ERR (4EH)
This message warns the remote device of a communications fault encountered during message transmission due, for example, to a checksum error. An ERR message may be replaced with a "Rejection (RJC)" one, which terminates the current message transaction in midstream.
When it receives an ERR message, the sending device may either attempt to send out the last message a second time or terminate communication by sending out an RJC message.

Rejection: RJC (4FH)
This message is sent out when there is a need to terminate communication by overriding the current message. An RJC message will be triggered when:
- a WSD or RQD message has specified an illegal data address or size.
- the device is not ready for communication.
- an illegal number of addresses or data has been detected.
data transfer has been terminated by an operator. - a communications error has occurred.
An ERR message may be sent out by a device on either side of the interface. Communication must be terminated immediately when either side triggers an ERR message.
