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. Basically, generated performance messages are sent to external destinations while also
being transmitted to the Sound Generator Section. The channel number of the sent channel message is in accordance with
Instrument's instrument part number.
MIDI Output Performance Information
The following describes the performance information that is output and is not output as MIDI signals.
•
Output performance
–
–
Keyboard play by the performer
Auto accompaniment
•
Non-output performance

1.2
Sound Generator Section
The Sound Generator Section consists of a channel-independent common block and an independent instrument part specific
to each channel. Mainly it receives performance information and sound source setting information.
1.2.1
Sound Generator Common Block
The common block consists of system effects, mixer master control, etc. A number of the parameters of these items can
be controlled by universal system exclusive messages.

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.

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.

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.

When a MIDI implementation data value is expressed in
binary, the letter "B" (for "binary") is affixed at the end of
the value. The table below shows the binary equivalents for
the decimal values 0 through 127, which are often used for
settings.
