Part I

MIDI Message Overview

1 Product Configuration as a MIDI Device

As a MIDI device, the 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 acco rdance with its function.

• System Section – Device Settings

• Sound Generator Section – Common

∗ Sound Generator Common Block ∗ System Effect Block ∗ Master Effect Block (Brilliance Function) ∗ Mixer Ma ster Block

– Channel Independent

∗ Instrument Parts ∗ Insertion Effect Block ∗ Mixer Channel Independent Block

• Performance Controller Section – Keyboard – Pedal and other real-time controllers – Auto Accompaniment and Auto Accompaniment function

1.1 System Section

The System Section is divided between a sound generator and functions that are not directly related to Instrument play. In addition to manipulating Instrument setting parameters, this section is also used to exchange commands and information. For example, parameters can be initialized upon receipt of a System Section MIDI message, and memory use information can be sent.

1.2 Performance Controller Section

The Performance Controller Section consists of the keyboard, pedal and other real-time controllers, as well as blocks that generate auto accompaniment, auto performance, and other performance information. An operation causes the corresponding message to be transmitted to the sound generator and to be sent from MIDI OUT. The channel number of the sent message is in accordance with Instrument's part number.

1.3 Auto Accompaniment and Auto Performance MIDI Send

This document includes information for each type of information that describes what operation causes the message to be sent. However, since there are so many messages sent by an auto accompaniment or auto performance operation, those messages are not covered herein.

1.4 Sound Generator Section

The Sound Generator Section consists of a common part that does not depend on the channel and a part that specific to each channel. Mainly it receives performance information and performs operations.

1.4.1 Sound Generator Common Block

The common section consists of a sound generator setting blocks that do not depend on the sound generator part, such as system effects, mixer master control, etc. These can be controlled by system exclusive messages that are basically exclusive to this particular instrument, but several parameters also can be controlled by general universal system exclusive messages.

1.4.2 Part Block

The parts of the sound generator can be operated and their settings can be changed with Instrument-specific system exclusive messages and channel messages. This function consists of 32 parts, but channel messages can control only Group B. The following table shows the fixed relationships between the part numbers and channel numbers of channel messages.

2 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.

• Demo data performance in progress

• Music Library data performance in progress

• SD memory card format in progress

3 Timbre Type Specific Operation

The operation that is 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 part. Applicable information is provided in the explanations for each message.

Part II

Channel Message

4 Receive Channel

The channel number of the channel message received by each part is shown in the table under "1.4.2 Part Block". The channel number of a channel message that changes the settings of a DSP coincides with the channel of the part that is using the DSP.

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.

Receive

Receipt change the value of Parameter7 [0-7] (7-Bit Parameter) explained under "22.3 DSP Parameter". Any message received that corresponds to the parameter of a number not being used by the currently selected DSP is ignored.

Note 1: Received values and parameter setting values The range of the value of each DSP Parameter 7 array element depends on the selected DSP or array number. Unlike manipulation of a DSP parameter using a System Exclusive Message, a value rec eiv ed by this co ntrol ch ange me ssa ge is always a value from 0 to 127, but the value is changed in accordance with the setting range of the applicable parameter setting. Because of this, it is impossible for a value to be outside of the range of the applicable parameter setting. Conversion from the value received with the message to the parameter setting value is performed can be represented in general terms by the expression shown below.
