Part I MIDI Message Overview 1 Product Configuration as a MIDI Device As a MIDI device, this Instrument consists of the System Section, Performance Controller Section, and Sound Generator Section described below. Each of these sections can send and receive specific MIDI Messages in accordance with its function. 1.1 System Section The System Section manages the Instrument status and user data.
PAGE 6
1.3.2 Instrument Part Block The instrument part section consists of a total of 32 instrument parts, divided into two groups, named Group A and Group B of 16 instruments each. Each part can perform operations and setting changes using channel messages and Instrument’s system exclusive messages. Only Group B can be controlled by external channel messages. As shown in the following table, there is a fixed relationship between channel message receive channel numbers and instrument parts.

operation mode. For details, see the explanation for each message. 3 Conditions that Disable Message Send and Receive All MIDI message send and receive is temporarily disabled while any one of the following processes is in progress. • SD memory card operation in progress.
PAGE 8
Part II Channel Message 4 Receive Channel The channel number of the channel message received by each part is shown in the table under “1.3.2 Instrument Part Block”. 5 Send Channel Basically, the MIDI channel of the channel message sent when the Instrument is played coincides with the MIDI channel of the part being played. Note, however, that the MIDI channel of the performance information that corresponds to the keyboard main part depends on the Keyboard Channel setting value.
PAGE 9
Send This message is not sent by this Instrument. Receive This message is not received by this Instrument. 9 Control Change Message Format: n: cc: vv: BnH ccH vvH MIDI Channel Number Control Number Value Send Sent when the Instrument’s pedal is operated or when Instrument settings are changed. Receive Receipt changes the pedal and other performance conditions, and Instrument settings. 9.

Part IV Instrument-Specific System Exclusive Messages 19 Format This section explains the format of the Instrument-specific System Exclusive Messages. See “V Parameter List” and “VI Parameter Set List” for information about how parameter sets actually are transferred. 19.1 Message Classifications Basically, the operation that corresponds to Instrument-specific system exclusive messages is parameter data transfer.
PAGE 22
19.2 Basic Message Structure Instrument-specific system exclusive message operation can be broadly divided between two methods: Individual Parameter Transfer (single parameter send/receive) and Bulk Parameter Set Transfer (batch parameter send/receive). Each method includes a number of diﬀerent messages. The field in the SysEx message that specifies the message type is the action (act) field. The format of the body part of the message depends on the act value.
PAGE 23
19.3.4 dev : MIDI Device ID 00H - 7FH Format: 0dddddddB The contents of this field in 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. When a message containing 7FH is received, receipt of the message is always allowed, regardless of the Instrument’s ID setting. Note, however, that the Instrument does not have a specific Device ID, so use only 7FH for send and receive. 19.3.
PAGE 24
HBR:Handshake Bulk Parameter Set Request Indicates a send request message using the parameter set image handshake mode. When the Instrument receives this action, it uses an HBS message to return the specified parameter set. HBS:Handshake Bulk Parameter Set Send Indicates a parameter set image send message using handshake mode. The parameter set to be transferred is divided into multiple packets when it is greater than a prescribed size. The packets are transferred in accordance with handshake mode.

PAGE 26
Block Bit Field Division When the parameter block has a multi-dimensional array structure, bit 21 of the block number is divided into prescribed bit fields based on the rules explained below. • Case 1 When an array has three or fewer nesting levels and the number of arrays in each dimension is 128 or less, they are assigned below the three 7-bit fields. Unused regions are filled will zeros.
PAGE 27
19.3.13 Format: len : Data Length LSB MSB 0lllllllB 0mmmmmmmB As shown below, the meaning of this field diﬀers depending on whether an individual transfer or a bulk parameter set transfer is being performed. Individual Parameter Transfer Data length indicates the length of the array being transferred minus 1 when the parameter contains a character string or other similar array structure. Bulk Parameter Set Transfer Data length indicates the number of bytes of data included within a packet.
PAGE 28
19.3.15 Single Parameter Data Size Limit With the Instrument’s system exclusive message format, the size of a single message cannot exceed 256 bytes. The data size and the array size, however, can cause a packet to exceed 256 bytes when transferring a single parameter array. In this case, the IPS and IPR message data length and data index number values can be modified to enable division of a single parameter value into multiple messages so it can be sent that way. 19.3.
PAGE 29
19.3.18 EOX : End of System Exclusive Message Format: 11110111B This is the End of System Exclusive Message status byte established by the MIDI standard. 20 Individual Parameter Operations There are two parameter unit operations: Individual Parameter Transfer and Individual Parameter Request.
PAGE 30
Session “One session” refers to a series of processes that occur for one user operation. One subsession or multiple subsessions make up a session. The sender sends EOS (End of Session) to end a session. Regardless of whether there is a single parameter set or multiple parameter sets being transferred, a bulk dump always takes the form of a session, never a subsession only. 21.

Part V Parameter List This section explains the parameters that actually can be transferred by the Instrument. 22 Using the Parameter List • Parameter field Shows the parameter name. • ID field Shows the parameter ID as a hexadecimal number. • R/W field Shows “R” to indicate that an IPR (Individual Parameter Request) read operation (Read) is possible or “W” to indicate that an IPS (Individual Parameter Send) write operation is possible. • Block field Shows the bit field allocation of the block number.

Part VIII MIDI Implementation Notation 34 34.1 Value Notation Hexadecimal Notation MIDI implementation sometimes requires that data be expressed in hexadecimal format. Hexadecimal values are indicated by the letter “H” after the value. The hexadecimal equivalents of decimal values 10 through 15 are expressed as the letters A through F. The table below shows the hexadecimal equivalents for decimal values 0 through 127, which are often used in MIDI messages.
