Part I MIDI Message Overview 1 Product Configuration as a MIDI Device In terms of a MIDI device, this Instrument consists of a Performance Controller Section and Sound Generator Section. 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.
PAGE 4
1.2.2 Instrument Part Block The instrument parts of the sound generator can be operated or their settings can be changed with channel messages. The 32 instrument parts of this Instrument are divided between Group A and Group B, each of which has 16 instrument parts. 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.
PAGE 5
2 Timbre Type Specific Operation The sound source operation performed for a received message depends on the current Timbre Type value (see "11.1 About the Timbre Type), which is the operation mode of each sound generator instrument part. For details, see the explanation for each message. 3 Conditions that Disable Message Send and Receive All MIDI messages send and receive is disabled during auto play by the Instrument.
PAGE 6
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 is the Keyboard Channel setting value.

.5 Pan (0AH) Format Message Format: BnH 0AH vvH n: MIDI Channel Number vv: Value (Note1) Note 1: For information about the relationship between setting values and send/receive values, see "19.3 Pan Setting Value Table" in "Part IV Setting Values and Send/Receive Values". Send Sent when auto accompaniment is used. Receive Receipt changes the pan setting of the corresponding part. 9.
PAGE 10
Timbre Type Specific Operation This operation differs in accordance with the Timbre Type (see "11.1 About the Timbre Type") 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. 9.
