1. Channel messages
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 = 0 (C-2)...60 (C3)...127 (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...4."
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 voice selects the voice bank.
The voice bank is selected by the combination of two control
change messages: MSB and LSB.
The function of the MSB and LSB will differ depending on
the sound module mode.
In the case of "XG," the MSB value will specify the major
division of voices, and the LSB value will specify the detailed
division.
In the case of "TG300B," the LSB value is fixed, and only
the MSB value will specify the detailed voice division.
In the case of "C/M," Bank Select is not received.
Control# Parameter Data Range
0 Bank Select MSB 0...127
32 Bank Select LSB 0...127
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 Breath Controller
Control# Parameter Data Range
2 Breath Controller 0...127
Valid only when a VL sound is selected.
1.2.4 Foot Controller
Control# Parameter Data Range
4 Foot Controller 0...127
Valid only when a VL sound is selected.
1.2.5 Portamento Time
This message controls the degree of Portamento (refer to
1.2.11).
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.
