MIDI Data Format
With a value of 0 there will be no sound, and with a value of
127 the volume will be maximum.
1.2.8 Hold1
This message controls sustain pedal on/off.
The notes that are sounding while the pedal is pressed will be
sustained.
Control# Parameter Data Range
64 Hold1 0...63,64...127
(OFF , ON)
For data of 0...63 the sustain pedal will be OFF (released), and
for data of 64...127 it will be on (pressed).
When this is ON, currently-sounding notes will continue to
sound even if note-off messages are received.
If the Multi Part parameter Rcv HOLD1 = OFF, that part will not
receive Hold1.
1.2.9 Portamento
This message controls portamento pedal on/off.
When the pedal is pressed, a portamento effect will be applied.
Control# Parameter Data Range
65 Portamento 0...63,64...127
(OFF , ON)
For data of 0...63 the portamento pedal will be OFF (released),
and for 64...127 it will be ON (pressed).
When this is ON, the pitch will change smoothly between notes.
The time over which the pitch changes is adjusted by
Portamento Time (see 1.2.3).
Also, when the Multi Part parameter MONO/POLY MODE =
MONO, the tone will also change smoothly (legato) if
Portamento = ON.
If any of the following Multi Part parameter settings apply, that
part will not receive Portamento.
•Rcv PORTAMENTO = OFF
•PART MODE=DRUM, DRUMS1,2
1.2.10 Sostenuto
This message controls sostenuto pedal on/off.
Notes which were already pressed when the pedal was pressed
will be sustained.
Control# Parameter Data Range
66 Sostenuto 0...63,64...127
(OFF , ON)
For data of 0...63, the sostenuto pedal will be OFF (released),
and for 64...127 it will be ON (pressed).
If sostenuto is turned on while a note is sounding, that note will
be sustained until sostenuto is turned OFF.
If the Multi Part parameter Rcv SOSTENUTO = OFF, that part
will not receive Sostenuto.
1.2.11 Soft Pedal
This message controls soft pedal on/off.
The sound will become more mellow while the pedal is pressed.
Control# Parameter Data Range
67 Soft Pedal 0...63,64...127
(OFF , ON)
For data of 0...63, the soft pedal is OFF (released), and for
64...127 it is ON (pressed).
If any of the following Multi Part parameter settings apply, that
part will not receive the Soft Pedal.
•Rcv SOFT PEDAL= OFF
•PART MODE=DRUM,DRUMS1,2
1.2.12 Harmonic Content
This message adjusts the resonance of the filter that is
specified for the sound.
The value of 0~127 is taken as -64~+63, and added as an
offset value to the original sound data to modify the resonance.
Control# Parameter Data Range
71 Harmonic Content 0...64...127
(-64...0...+63)
Since this is a relative change parameter, it specifies a boost or
cut relative to 64.
Higher values will produce a more distinctive sound.
For some sounds, the effective range may be less than the
possible range of settings.
1.2.13 Release Time
This message adjusts the EG release time that was specified
by the sound data.
The value of 0~127 is taken as -64~+63, and added to the
original sound data as an offset value to modify the release
time.
Control# Parameter Data Range
72 Release Time 0...64...127
(-64...0...+63)
Since this is a relative change parameter, it specifies an
increase or decrease relative to 64.
Increasing this value will lengthen the release that follows a
note-off.
1.2.14 Attack Time
This message adjusts the EG attack time that was specified by
the sound data.
The value of 0~127 is taken as -64~+63, and added to the
original sound data as an offset value to modify the attack time.
Control# Parameter Data Range
73 Attack Time 0...64...127
(-64...0...+63)
Since this a relative change parameter, it specifies an increase
or decrease relative to 64.
Increasing this value will make the attack more gradual, and
decreasing this value will make the attack sharper.
1.2.15 Brightness
This message adjusts the cutoff frequency of the low pass filter
specified by the sound data.
The value of 0~127 is taken as -64~+63, and added to the
original sound data as an offset value to modify the cutoff
frequency
Control# Parameter Data Range
74 Brightness 0...64...127
(-64...0...+63)
Since this is a relative change parameter, it specifies an
increase or decrease relative to 64.
Lower values will produce a more mellow sound.
For some sounds, the effective range may be less than the
possible range of settings.
