MIDI Message Overview

1 Product Configuration as a MIDI Device

As a MIDI device, the instrument consists of the System Section, Sound Generator Section, and Performance Controller Section described below. Each of these sections sends and receives specific MIDI Messages in accordance with its function.

• System Section

– Device settings

– Function status

• Sound Generator Section

– Common

 Sound generator common section  System effects  Brilliance adjustment function  Mixer master

– Parts

 Sound generator instrument parts  DSP (insertion effects)  Mixer channel

• Performance Controller Section

– Keyboard

– Pedal and other real-time controllers

– Auto play function

– Auto Accompaniment

1.1 System Section

The System Section consists of a sound generator (sound source), a performance controller part (performance), and functions that are not directly related to Instrument play. In addition to manipulating Instrument setting parameters, this section is also used to exchange information.

1.2 Sound Generator Section

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

1.2.1 Sound generator common section

The common section consists of 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.

1.2.2 Parts

The settings of the sound generator parts can be changed using Instrument-specific system exclusive messages. This Instrument consists of 48 parts. Of these, channel messages can be used to perform note on operations and to change settings of only the C Group (C01 through C16). The relationships between the channel message receive channel and part number are fixed, as shown in “1.2.3 Part Assignments”.

Note 1:

Can be changed by the Keyboard Channel setting.

Note 2:

Sent during recorder play only. When there is no data recorded in the applicable recorder track, the MIDI information of the functions of parts with the same send channel (A01 through A16) is sent.

1.3 Performance Controller Section

The Performance Controller Section consists of keyboard, pedal and other real-time controllers, as well as blocks that generate auto accompaniment, auto performance, and other performance information. These messages are transmitted to the sound generator in accordance with operations, while they are also being sent out as MIDI messages. The channel number of the sent message is in accordance with Instrument’s part number.

1.3.1 Auto Accompaniment and Auto Performance MIDI Send

This document what operation is sent by a message in the case of each message type. However, since there are so many messages sent by an auto accompaniment operation when auto performance and Accomp MIDI Out is turned on, those messages are not covered here.

2 Conditions that Disable Message Send and Receive

All MIDI message send and receive is temporarily disabled in all of the following cases.

• During instrument startup

• During SD card formatting

• During user data initialization

• Immediately after the recorder is exited

• During storage of registration data

• While storage is selected as the USB device mode

3 Timbre Type Specific Operation

The operation that is performed for a received message depends on the current Timbre Type setting (see “11.1 About Timbre Type”), which is the operation mode of each sound generator part. Applicable information is provided in the explanations for each message.

4 Send Channel

For information about the MIDI channels of the channel messages that are sent when this Instrument is played, see “1.2.3 Part Assignments”.

Note, however, that the MIDI channel of the performance information that corresponds to the keyboard main part can be changed by the Keyboard Channel setting value.

5 Receive Channel

For information about the MIDI channel numbers of channel messages received by each part, see “1.2.3 Part Assignments”.

The MIDI channel number of a channel message that changes DSP settings also coincides with the MIDI channel of the part using the DSP. A channel message is not received by a part that is turned off by the Part Enable Parameter value explained under “20.7 Part Parameters”.

This message is not sent by this Instrument.

Receipt change the value of Parameter7 [0-7] (7-Bit Parameter) explained under “21.3 DSP Parameters”. Any message received that corresponds to the parameter of a number not being used by the currently selected DSP is ignored.

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 received by this control change message is always in the range of 0 to 127, but the range 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. Conversion to the parameter setting value from the value received with the message can be represented in general terms by the expression shown below.

That is to say that legato play is performed.
