Part I
Overview
1 Product Configuration as a MIDI Device
As a MIDI device, this Instrument consists of the System Section, Sound Generator Section, and Per-
formance Controller Section described below. Each of these sections can send and receive specific MIDI
Messages in accordance with its function.
1.1 System Section
The System Section manages the Instrument status.
1.2 Performance Controller Section
The Performance Controller Section performs generates performance messages in accordance with key-
board play and pedal operations, 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 the Instrument’s part number.
1.3 Sound Generator Section
The Sound Generator Section mainly performs receive of performance information and sound source
setting information. It consists of a common part that does not depend on the channel and a musical
instrument part that is independent of each channel.
1.3.1 Sound Generator Common Block
The common block consists of system effects, master control, etc. These can be controlled by general
universal system exclusive messages, or the Instrument’s system exclusive messages or all.
1.3.2 Instrument Part Block
The instrument part section consists of a total of 32 instrument parts. The settings of each part can be
changed using channel messages or Instrument’s system exclusive messages or all. The functions assigned
to each part are shown below. The MIDI send channel and MIDI receive channel can be changed using
the Instrument’s MIDI settings.

Part II
Channel Message
Instrument Velocity Resolution The upper seven bits of the 14-bit resolution correspond to the
Note On/Off message, while the lower seven bits correspond to the High Resolution Velocity Prefix
message.
Note On/Off High Resolution Velocity Prefix
Upper 7 bits Lower 7 bits
14bits
The initial default value for the lower 7 bits is 00H. Receipt of a High Resolution Prefix message
causes the lower seven bits to be set, but note on/off is not performed.
Receipt of a Note On/Off message causes the upper seven bits to be set with note on/off performed
with 14-bit resolution Velocity.
The High Resolution Velocity Prefix message corresponds the message immediately following the Note
On/Off message, and the lower seven bits are cleared to 00H immediately following note on/off by the
Note On/Off message. 7-bit resolution note on/off using only the Note On/Off message also continues
to be supported.
For details about each message, see ” 3 Note Off”, ”4 Note On”, and ”5.18 High Resolution Velocity
Prefix”.
3 Note Off
Format
Message Format: 8nH kkH vvH
9nH kkH 00H(receive only)
n: MIDI Channel Number
kk: Key Number
vv: Velocity
Transmit Sent when something is played on the keyboard. The key number changes in accordance
with on the Transpose function and Octave Shift function.
Receive Receipt stops a note being sounded by a note on message.
When a High Resolution Velocity Prefix message is received immediately prior to the Note Off message
and the lower seven bits of the 14-bit Velocity are set, the 14-bit resolution note off of the note being
sounded is performed.
For information about the relationship between the Note On/Off message and High Resolution Ve-
locity Prefix message, see ”Instrument Velocity Resolution” at the beginning of part II.
Note off by making the Note On Velocity 00H is identical to note off by the combination of High
Resolution Velocity prefix message 40H and Note Off Message 40H.
6

Note: This Instrument has a function that assumes connection of an external device that sends Note Off Velocity as a fixed
value. Note Off Velocity 00H is replaced with 40H until a Note Off message with a Velocity value other than 00H is received. This
function is enabled when the Instrument is turned on, and disabled by receipt of a Note Off message with a Velocity value other
than 00H.
4 Note On
Message Format: 9nH kkH vvH
n: MIDI Channel Number
kk: Key Number
vv: Velocity
Transmit Sent when something is played on the keyboard. The key number changes in accordance
with on the Transpose function and Octave Shift function.
Receive Receipt sounds a note of the corresponding instrument part.
When a High Resolution Velocity Prefix message is received immediately prior to the Note On message
and the lower seven bits of the 14-bit Velocity are set, the 14-bit resolution note on is performed.
For information about the relationship between the Note On/Off message and High Resolution Ve-
locity Prefix message, see ”Instrument Velocity Resolution” at the beginning of part II.
