MIDI Data Format

1.3.7 Poly

Perform the same processing as when All Sound Off is
received, and set the corresponding channel to Mode3*.
Control# Parameter Data Range
127 Poly 0
* Mode3 is a state in which only channel messages on the specified
channel will be received, and note will be sounded polyphoni-
cally.

1.4 Program change

This message reports voice selection and changes the program
number of the receiving channel.
In order to include changes to the voice bank, Program Change
and Bank Select messages must be sent as a set (see 1.2.1)
If the Multi Part parameter Rcv PROGRAM CHANGE = OFF,
that part will not receive program changes.

1.5 Pitch bend

This message conveys movements of the pitch bender.
This message is generally used to modify the pitch of a part,
but the depth of the following seven effects can be controlled.
The effect of this message can be modified by the following
parameters.
•Multi Part Parameter
1. BEND PITCH CONTROL
2. BEND FILTER CONTROL
3. BEND AMPLITUDE CONTROL
4. BEND LFO PMOD DEPTH
5. BEND LFO FMOD DEPTH
6. BEND LFO AMOD DEPTH
•Effect1 Parameter
7. BEND VARIATION CONTROL DEPTH
(Valid when Variation Effect is assigned to a part as
Insertion)
By default, the Pitch Control effect is applied.
If the receive channel is a drum part, effects 5 and 6 will not
apply.
If the Multi Part parameter Rcv PITCH BEND CHANGE = OFF,
that part will not receive pitch bend messages.

1.6 Channel aftertouch

This message conveys the pressure which is applied to the
keyboard after playing a note in order to create tonal changes
(for an entire MIDI channel).
The pressure can be controlled for each part. This message will
affect the currently-sounding notes.
The effect of this message will be determined by the settings of
the following parameters.
•Multi Part Parameter
1. CAT PITCH CONTROL
2. CAT FILTER CONTROL
3. CAT AMPLITUDE CONTROL
4. CAT LFO PMOD DEPTH
5. CAT LFO FMOD DEPTH
6. CAT LFO AMOD DEPTH
• Effect1 Parameter
7. CAT VARIATION CONTROL DEPTH
(Valid when the Variation Effect is assigned to a
part as Insertion)
By default, there will be no effect.
If the receive channel is a drum part, effects 5 and 6 will not
apply.
If the Multi Part parameter Rcv CHANNEL AFTER TOUCH =
OFF, that part will not receive Channel Aftertouch.

1.7 Polyphonic aftertouch

This message conveys the pressure that is applied to the
keyboard after playing a note (for individual note numbers).
The pressure can be controlled independently for each note.
This message will affect currently-sounding notes.
The effect of this message is determined by the following Multi
Part parameters.
1. PAT PITCH CONTROL
2. PAT FILTER CONTROL
3. PAT AMPLITUDE CONTROL
4. PAT LFO PMOD DEPTH
5. PAT LFO FMOD DEPTH
6. PAT LFO AMOD DEPTH
By default, there will be no effect.
The effect will apply to note numbers 36...97.
In the case of either of the following Multi Part parameter
settings, that part will not receive Polyphonic Aftertouch.
Rcv CHANNEL AFTER TOUCH = OFF
PART MODE = DRUM, DRUMS1,2
2. System exclusive messages
These MIDI messages are not directly “performance data,” but
are used to make settings related to the system of the MIDI
device.
For example, these messages can be used to save data
specific to this device on a MIDI data filer such as the MDF3.
By using these messages, it is possible to edit almost all
settings of the MU15 from an external MIDI device.
The device number of the MU15 is fixed to “All”. And when
sending these messages, it is fixed to “0”.

2.1 Parameter changes

[ UNIVERSAL REALTIME MESSAGE ]
1) Master Volume
[ UNIVERSAL NON REALTIME MESSAGE ]
1) General MIDI System On
2) Identity Request (INQUIRY MESSAGE)
3) Identity Reply (INQUIRY MESSAGE)
[ XG PARAMETER CHANGE ]
1) XG System on
2) XG System parameter change
3) Multi Effect1 parameter change
4) Display parameter change
5) Multi Part parameter change
6) Drums Setup parameter change
[ Others ]
1) Master tuning

2.1.1 Universal realtime messages

2.1.1.1 Master Volume

This system exclusive message is used to control the volume
of all channels simultaneously.
