MIDI Data Format
1. Channel messages
This device transmits only NOTE ON and NOTE OFF.
1.1 Note on/note off
These messages convey keyboard performance data. Note-on
is transmitted when a note is pressed, and note-off is
transmitted when a note is released. These messages contain a
note number which indicates the key that was played, and a
“velocity” which indicates how strongly it was played. When a
note-on of velocity “0” is received, it has the same effect as a
note-off.”
Range of note numbers received = C-2...G8
Velocity range = 1...127 (Velocity is received only for note-on)
When the Multi Part parameter “Rcv NOTE MESSAGE” = OFF,
that part will not receive these messages.
For a drum part*, key-off is not received if the DrumSetup
parameter Rcv NOTE OFF = OFF.
For a drum part, key-on is not received if the DrumSetup
parameter Rcv NOTE ON = OFF.
* Drum Part indicates that the Multi Part parameter PART MODE
is “set to DRUM or DRUMS1,2.”
1.2 Control changes
These messages control volume or pan etc.
Their functions are differentiated by the control number (Ctrl#).
If the Multi Part parameter Rcv CONTROL CHANGE = OFF,
that part will not receive control changes.
1.2.1 Bank Select
This message selects the voice bank.
The voice bank is selected by the combination of two control
change messages: MSB and LSB.
Control# Parameter Data Range
0 Bank Select MSB 0, 64, 126, 127
(Normal voice,SFX voice,
SFX kit, Drum kit)
32 Bank Select LSB 0...127
In the XG mode, MSB numbers select Voice type (Normal Voice
or Drum Voice), and LSB numbers select Voice banks.
In the TG300B mode, LSB is fixed, and MSB numbers select
Voice banks.
The Bank Select data will be processed only after a Program
Change is received, and then voice bank will change at that
time. If you wish to change the voice bank as well as the voice,
you must transmit Bank Select and Program Change messages
as a set, in the order of Bank Select MSB, LSB, and Program
Change.
1.2.2 Modulation
This message is used primarily to control the depth of vibrato,
but the depth of the following 7 types of effect can be
controlled.
The effect of this message can be changed by the following
parameters.
•Multi Part Parameter
1. MW PITCH CONTROL
2. MW FILTER CONTROL
3. MW AMPLITUDE CONTROL
4. MW LFO PMOD DEPTH
5. MW LFO FMOD DEPTH
6. MW LFO AMOD DEPTH
•Effect1 Parameter
7. MW VARIATION CONTROL DEPTH
(Valid when Variation Effect is assigned to a part as
Insertion)
By default, an LFO Pitch Modulation (PMOD) effect will apply.
Control# Parameter Data Range
1 Modulation 0...127
If the Multi Part parameter Rcv MODULATION = OFF, that part
will not receive Modulation.
If the receive channel is a drum part, effects 5 and 6 will not
apply.
1.2.3 Portamento Time
This message controls the degree of Portamento (refer to
1.2.9).
Control# Parameter Data Range
5 Portamento Time 0...127
When Portamento (control number 065) is ON, this regulates
the speed of the pitch change.
A value of 0 is the shortest portamento time, and 127 is the
longest portamento time.
If the receive channel is a drum part, Portamento Time is not
received.
1.2.4 Data Entry
This message sets the value of the parameter which was
specified by RPN MSB/LSB (see 1.2.22) and NRPN MSB/LSB
(see 1.2.21).
Control# Parameter Data Range
6 Data Entry MSB 0...127
38 Data Entry LSB 0...127
1.2.5 Main Volume
This message controls the volume of each part.
This is used to adjust the volume balance between parts.
Control# Parameter Data Range
7 Main Volume 0...127
When the Multi Part parameter Rcv VOLUME = OFF, that part
will not receive Main Volume.
With a value of 0 there will be no sound, and a value of 127 will
be the maximum volume.
1.2.6 Panpot
This message controls the panning (stereo location) of each
part.
Control# Parameter Data Range
10 Pan 0...64...127
When the Multi Part parameter Rcv PAN = OFF, that part will
not receive Panpot.
0 is left, 64 is center, and 127 is right.
1.2.7 Expression
This message controls expression (dynamics within a musical
line) for each part.
It is used to create volume changes during a song.
Control# Parameter Data Range
11 Expression 0...127
If the Multi Part parameter Rcv EXPRESSION = OFF, that part
will not receive Expression.
