Cutoff Key Follow
(Cutoff Key Follow Sensitivity)
Determines the degree to which the notes
(specifically, their position or octave range) affect
the “Cutoff” (set above) of the selected Element,
assuming C3 as the basic pitch. A positive setting
will lower the Cutoff frequency for lower notes and
raise it for higher notes. A negative setting will have
the opposite effect.
Settings: -200% – +0% – +200%
HPF Cutoff
(High Pass Filter Cutoff Frequency)
Determines the central frequency for the Key Follow parameter (below) of the HPF. This parameter is
available only when filter types LPF12 or LPF6 are selected.
Settings: 0 – 255
HPF Key Follow
(High Pass Filter Cutoff Key Follow
Sensitivity)
Determines the degree to which the notes (specifically, their position or octave range) affect the
“Cutoff” (set above) of the HPF. A positive setting will lower the Cutoff frequency for lower notes and
raise it for higher notes. A negative setting will have the opposite effect. A setting of 0 will result in no
change in the note. This parameter is available only when filter types LPF12 or LPF6 are selected.
Settings: -200% – +0% – +200%
FEG (Filter EG)
Time Determines the time settings for the Filter EG. The
Time parameters let you set the time between the
adjoining points of the level parameters below.
When the current Level setting is the same as the
next, the corresponding Time indicates the length of
time for which the Level is held at the current
setting. A higher value results in a longer time until
reaching the next level.
Settings: 0 – 127
Hold Time
Determines the time between the moment a Note On message
is received and the moment the envelope starts to rise.
Attack Time
Determines the speed of attack from the initial cutoff frequency
(Hold Level) to the maximum level (Attack Level) of the Voice after the hold time has elapsed.
Decay 1 Time
Determines how fast the envelope falls from the maximum cutoff frequency (Attack Level) to the cutoff frequency specified
as the Decay 1 Level.
Decay 2 Time
Determines how fast the envelope falls from the cutoff frequency specified as the Decay 1 Level to the cutoff frequency
specified as the Decay 2 Level.
Release Time
Determines how fast the envelope falls to the cutoff frequency specified as the Release Level when a Note Off message is
received.
Level Determines the level settings for the Filter EG. The Level parameters let you set the amount of the
filter change at each point based on the cutoff frequency specified in the Filter Type (page 76).
Settings: -128 – +0 – +127
Hold Level
Determines the initial cutoff frequency at the moment a Note On message is received.
Attack Level
Determines the maximum cutoff frequency which the envelope reaches after a Note On message is received.
Decay 1 Level
Determines the cutoff frequency to which the sound changes from the Attack Level after the Decay 1 Time elapses.
Decay 2 Level
Determines the cutoff frequency which will be maintained while a note is held.
Release Level
Determines the final pitch reached after a Note Off message is received.
Time Velocity Sens
(EG Time Velocity Sensitivity)
Determines how the FEG transition time (speed) responds to velocity, or the strength with which the
note is pressed. When this is set to a positive value, high velocities result in a fast FEG transition
speed while low velocities result in a slow speed, as shown below. When this is set to a negative
value, the opposite effect is produced: High velocities result in a slow FEG transition speed while low
velocities result in a fast speed. When this is set to 0, the FEG transition speed does not change no
matter what the velocity.
Settings: -64 – +0 – +63
