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 Per-
formance 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(PX-350M, AP-650M)
1.1 System Section
The System Section consists of a sound generator (sound source), a performance controller part (per-
formance), 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.
5

1.2.2 Parts
The settings of the sound generator parts can be changed using Instrument-specific system exclusive
messages. This Instrument consists of 32 parts. Of these, channel messages can be used to perform
note on operations and to change settings of only the B Group (B01 through B16). The relationships
between the channel message receive channel and part number are fixed, as shown in ”1.2.3 Part
Assignments(PX-150,PX-750,PX-850,PX-1200GP, AP-250,AP-450)” and ”1.2.4 Part Assignments(PX-
350M, AP-650M)”.

Note2 :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(PX-350M, AP-650M), those messages are not covered here.
2 Conditions that Disable Message Send and Receive
The main conditions when MIDI message send and receive are disabled by the Instrument are those
described below.
•During storage of registration data(PX-350M, AP-650M)
•While storage is selected as the USB device mode(PX-850,PX-1200GP, AP-450,PX-350M, AP-
650M)
3 Timbre Type Specific Operation
The operation that is performed for a received message depends on the current Timbre Type setting (see
10.1 About Timbre Type ), which is the operation mode of each sound generator part. Applicable
information is provided in the explanations for each message.

Channel Message
4 Channel Message Overview
4.1 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(PX-150,PX-750,PX-850,PX-1200GP, AP-250,AP-450)and1.2.4
Part Assignments(PX-350M, AP-650M) . 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.
4.2 Receive Channel
For information about the MIDI channel numbers of channel messages received by each part, see1.2.3
Part Assignments(PX-150,PX-750,PX-850,PX-1200GP, AP-250,AP-450)and1.2.4 Part Assignments(PX-
350M, AP-650M) . 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19.6 Part Parameter .
4.3 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. (Note1)
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 ”5Note Off”, ”6Note On”, and ”8.17 High Resolution Velocity
Prefix”.
Note1 :The PX-150,PX-750, AP-250, and PX-350M do not support Note Off Velocity. For these models, Velocity for send
Note Off messages is a fixed value (40H). Velocity for receive Note Off messages is ignored. The High Resolution Velocity Prefix
message is not sent or received for a Note Off message.

The key number changes in accordance with on the Transpose function and Octave Shift function.
Note1 :The PX-150,PX-750, AP-250, and PX-350M do not support Note Off Velocity. For these models, Velocity for send
Note Off messages is a fixed value (40H). The High Resolution Velocity Prefix message is not sent for a Note Off message.
Receive Receipt stops a note being sounded by a note on message. (Note1)
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 ”4.3 Instrument Velocity Resolution”.
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.
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.
Note1 :The PX-150,PX-750, AP-250, and PX-350M do not support Note Off Velocity. Velocity for receive Note Off
messages is ignored. The High Resolution Velocity Prefix message is not received for a Note Off message.

Dsp Parameter . 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.
