24 Part IV Instrument-Specific System Exclusive Messages 19 Format This section expla ins the format of the Ins trument-specific S ystem Exclusive M essages. Se e "Part V Parameter L ist" and "Part VI Parameter Set List" for information about how parameter sets actually are transferred.
25 19.2 Basic Message Structure Instrument-specific system exclusive me ssage operation can be broa dly divided between two me thods: Individual Parameter T ransfer (single parameter send/receive) and Bulk Parameter Set T ran sfer (batch parameter se nd/receive).
26 19.3.4 dev : MIDI Device ID 00H-7 FH The contents of this field i n a received message are compared with the Model's MIDI Device ID, and receipt of the incoming message is allowed only when the two IDs match.
27 HBS: Handshake Bulk Parameter Se t Send Indicates a paramete r set image send message using handshake m ode. The parameter set to be transferred is divided into multiple packets when i t is greater than a prescribed size . Th e packets are tra nsferred in ac cordance with handshake mode.
28 19.3.6 cat : Category 0cccccccB = Category (7bit) The category indicates the categor ies of data handled by the Syst em Exclusive Mess age. The ID number (ID) of the Category is indicated on the left , while the communica ti on operation (Action) is ind icated on the right.
29 19.3.9 blk : Block Number The block number is a supplementary number that specifies which bloc k parameter is to be accessed. Block Bit Field Division When the parameter block has a multi-dimensional array structur e, bit 21 of the blo ck number is divided into prescribed bit fields based on the rules explained below .
30 19.3.13 len : Data Length As shown below , the meaning of this fi eld dif fers depending on whether an indi vidual transfer or a bulk parameter set transfer is being performed.
31 19.3.16 img : Param eter Set Image For a bulk data transfer operation, the para meter set data to be transferred is read sequent ially in 16-bit units starting from the top address. Read values are d ivided into 3-byte segments as shown below , and then sent in sequence.
32 20 Individual P arameter Operations There are two parameter unit operations: Individual Pa rameter Transfer and Ind i vidual Parameter Request. For one session, in response to an IPR (In dividual P.
33 21.1.2 Session and Subsession Subsession "One subsession" refers to transfer of one parameter set. A subse ssion transfers one parameter set or a parameter set that has been divided into multiple packets for transfer , with EOD (End of Data) at the end to terminate the send.
34 21.3 Handshake Mode Comm unication Flo w A session starts with the rece iving device sending a request us ing a HBR, or with the sending device sending HBS data. The sending device does not send the next packet until it rece ives an ACK from the receiving device.
35 The packed with the same packet number is resen t when a checksum mismatch or incompatib le data format error is detected. Session terminates if ERR is detected a number of times.
36 RJC is sent to terminate the session in case ACK cannot be recognize d. The session can be cancel ed for any reason by sending an RJC. RJC can be sent by the se nding device or the receiving device. The bulk dump session is terminat ed immediately upon receipt of an RJC.
