MIDI data format
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
71 Harmonic Content
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
72 Release Time
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
73 Attack Time
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

MU100 MIDI
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.
1.2.16 Portamento Control
This message specifies the portamento source key number
(the key number at which portamento will begin).
Data of 0...127 specifies the portamento source key.
When Portamento Control is received, the currently-
sounding pitch will change at a Portamento Time of 0 to the
key of the next-received note-on of the same channel.
Control# Parameter
84 Portamento Control
This is received even if Rcv PORTAMENTO = OFF.
Has no effect on VL sounds.
1.2.17 Effect1 Depth(Reverb Send Level)
This message specifies the send level for the reverb effect.
Control# Parameter
91 Effect1 Depth
Increasing this value will produce a richer reverb. The effect
of the value will depend on the state of the reverb effect.
1.2.18 Effect3 Depth(Chorus Send Level)
This message specifies the send level for the chorus effect.
Control# Parameter
93 Effect3 Depth
Raising this value will increase the modulation or spacious-
ness. The effect of the value will depend on the state of the
chorus effect.
1.2.19 Effect4 Depth (Variation Effect Send
Level)
This message specifies the send level for the variation effect.
Control# Parameter
94 Effect4 Depth
However, this is not received if the Variation Effect
parameter Variation Connection = 0 (Insertion).
1.2.20 Data Increment/Decrement (for RPN)
After RPN (see 1.2.22) is used to specify a parameter such
as Pitch Bend Sensitivity, Fine Tune, or Coarse Tune, this
message is used to increment or decrement the respective
parameter value in steps of 1.
Control# Parameter
96 RPN Increment
97 RPN Decrement
The data byte is ignored.
