Part I MIDI Message Overview 1 Product Conﬁguration as a MIDI Device As a MIDI device, this Instrument consists of the 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 Performance Controller Section The Performance Controller Section performs keyboard play and controller operations, and generates performance messages in accordance with auto play, etc.

Part II Channel Message 4 Receive Channel The channel number of the channel message received by each part is shown in the table under “1.2.2 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 MIDI Out Channel setting value.

Message Format: n: cc: vv: BnH ccH vvH MIDI Channel Number Control Number Value For details about messages, see each section of this manual that covers them. 8.1 Bank Select (00H,20H) Message Format: n: mm: ll: Note1 : BnH 00H mmH (MSB) BnH 20H llH (LSB) MIDI Channel Number MSB Value(Note1) LSB Value(Send:00H, Receive:Ignored) For details about the relationship between the MSB value and the tone, see the Tone List that comes with the Instrument. Transmit Sent when a tone is selected.

.4 Data Entry (06H,26H) Message Format: n: mm: ll: BnH 06H mmH (MSB) BnH 26H llH (LSB) MIDI Channel Number MSB Value LSB Value Transmit Sent when there is a change to the parameter assigned to RPN. Receive Receipt changes the parameter assigned to RPN. 8.5 Volume (07H) Message Format: n: vv: BnH 07H vvH MIDI Channel Number Value Receive Receipt changes the volume of the corresponding part. 8.

Receive Receipt performs an operation equivalent to a sustain pedal operation. Timbre Type Speciﬁc Operation This operation diﬀers in accordance with the Timbre Type (see “About the Timbre Type” in “10 Program Change”) setting. • Timbre Type: Melody Sustain oﬀ/on control is performed in accordance with the value of the received message. • Timbre Type: Drum The received message does not aﬀect sound source operation. 8.

Receive Receipt changes the ﬁlter resonance intensity. 8.13 Release Time (48H) Message Format: n: vv: Note1 : BnH 48H vvH MIDI Channel Number Value (Note1) For information about the relationship between setting values and send/receive values, see the “15.2 –64 - 0 - +63 Setting Value Table” in “IV Setting Values and Send/Receive Values” of this document. Transmit Sent when Sustain function of the instrument is operated.
PAGE 11
Receive Receipt of this message ﬁrst stores the Source Note Number for the next note. When the next Note On is received, the portamento eﬀect is applied to the note using this Source Note Number as the pitch start point and the Note On event key number as the end point. If there already is a note being sounded by Source Note Number at this time, the new note on is not performed and the portamento eﬀect is applied to the pitch of the note being sounded. That is to say that legato play is performed. 8.

8.18.3 Channel Coarse Tuning Message Format: n: mm: ll: BnH 64H 02H BnH 65H 00H BnH 06H mmH BnH 26H llH MIDI Channel Number MSB Value LSB Value Receive Receipt changes the coarse tune of the corresponding part. Does not aﬀect sound source operation when the Timbre Type (see “About the Timbre Type” in “10 Program Change”) is Drum. 8.18.4 RPN Null Message Format: n: BnH 64H 7FH BnH 65H 7FH MIDI Channel Number Transmit Sent when an RPN message send operation is performed.
PAGE 13
Receive Receipt releases (key release) all voices that are sounding. 9.4 Omni Mode Oﬀ (All Notes Oﬀ ) (7CH) Message Format: n: BnH 7CH 00H MIDI Channel Number Receive Receipt performs the same operation as when All Notes Oﬀ is received. 9.5 Omni Mode On (All Notes Oﬀ ) (7DH) Message Format: n: BnH 7DH 00H MIDI Channel Number Receive Receipt performs the same operation as when All Notes Oﬀ is received. 9.

About the Timbre Type Tones that are selected by each Instrument part have an attribute that depends on the sound source operation type. This attribute is called the “timbre type,” which is one of the types described below. • Melody This timbre type optimizes for normal melody tones. • Drum This setting optimizes for drum sounds. The damper pedal does not function. The Damper Pedal (Sustain), Channel Coarse Tune, and Master Coarse Tune messages are ignored if they are received.
PAGE 15
Part III System Message 13 Active Sensing Message Format: FEH Receive Once this message is received, the Active Sensing mode is entered. If no MIDI message is received for a speciﬁed amount of time, voices being sounded by this Instrument’s sound source are released, the controller is reset, and the Active Sensing mode is exited. 14 System Exclusive Message Message Format: F0H....F7H The Instrument sends and receives universal system exclusive messages. 14.
PAGE 16
Transmit Sent when Transpose is changed. Receive Receipt changes the Transpose parameter. Does not aﬀect sound source operation when the Timbre Type (see “About the Timbre Type” in “10 Program Change”) is Drum. 14.1.4 Reverb Type Message Format: vv: Note1 : F0H 7FH 7FH 04H 05H 01H 01H 01H 01H 01H 00H vvH F7H Value(Note1) For information about the relationship between setting values and send/receive values, see “15.

Part V MIDI Implementation Notation 16 16.1 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.
