MIDI note number
Note-off messages
These messages are transmitted when you release a
note. A Note-off message contains the following 3
types of information.
Note-off
: a note was released
Note number
: which note was released
Velocity
: how quickly it was released
The XP-10 receives Note-off messages, but ignores the
note-off velocity.
Pitch Bend messages
These messages indicate the position to which the
Pitch Bender was moved.
Aftertouch messages
These messages indicates how strongly the keyboard
was pressed after playing a note. There are two types
of Aftertouch message; Channel Aftertouch which
applies to an entire channel, and Polyphonic
Aftertouch which applies to an individual note. The
XP-10 is not able to transmit Aftertouch messages. In
order for the XP-10 to receive Aftertouch messages,
you must use Exclusive messages to turn aftertouch
reception on and to specify the effect which after-
touch messages will control. For details refer to the
MIDI Implementation (p.92).
Program Change messages
These messages select sounds.
Control Change messages
These messages transmit various types of data to
make a performance more musically expressive, for
example to control vibrato, hold, expression or pan.
The XP-10 can use the value of Control Change num-
ber 0 to select Variations of a Tone.
System messages
System messages include Exclusive messages, syn-
chronization-related messages, and messages that
help to keep a system running smoothly. Exclusive
messages are the main type of messages in this group
that the XP-10 uses.

Exclusive messages
These messages are used to convey information that is
specific to a particular device, such as sound data. In
general, they can be transmitted and received only
between devices of the same model and manufacturer.
The XP-10 can use exclusive messages to store sound
data settings and system settings on a sequencer.
* In order to transmit and receive Exclusive mes-
sages, the Device ID number of both devices must
be set to match (p.46).
About the MIDI Implementation Chart
A variety of messages can be transmitted using MIDI,
but not all devices will necessarily be able to transmit
and/or receive all types of MIDI message. To see which
types of MIDI message a device can transmit and
receive, refer to the MIDI Implementation Chart that is
included in the manual of each device. Messages which
are marked by a circle O in the charts of both devices can
be transmitted between the two devices.
Selecting sounds via MIDI
Using MIDI, sounds on another device can be selected
from the XP-10, and sounds on the XP-10 can be
selected from the other device.
Selecting sounds on another device
using the XP-10
When you use the buttons on the XP-10's panel to
select Tones or Drum Sets, Control] Change messages
and a Program Change message that correspond with
the selected Tone or Drum Set will be transmitted
from MIDI OUT. These MIDI messages are transmit-
ted in the following order.
1. Control Change number 0 (Bank Select MSB)
(BnH 00H mmH)
2. Control Change number 32 (Bank Select LSB)
(BnH 20H HH)
3. Program number (CnH ppH)

* MIDI messages are not transmitted when you select
a different Tone or Drum Set by moving to a differ-
ent Part. MIDI messages are transmitted when you
select the Tone or Drum Set used by a Part.
* These messages for sound selection are transmitted
on the Transmit channel of the keyboard (refer to
"Set/check the Keyboard Transmit Channel" p.45).
* These messages for sound selection are not trans-
mitted when you select a Performance.
