Tone Parameters
Parameter Value Explanation
Cuto Keyfollow -200–+200
Use this parameter if you want the cuto
frequency to change according to the key
that is pressed.
Relative to the cuto frequency at the
key specied by Cuto Keyfollow Base
Point, positive “+” values cause the cuto
frequency to become higher as you play
above the reference key, and negative
“-” values cause the cuto frequency to
become lower.
Higher values will produce greater
change.

Cuto Velo Curve FIXED, 1–7
Selects one of the following seven curves
that determine how keyboard playing
dynamics (velocity) inuence the cuto
frequency.
Set this to “FIXED” if you don’t want the
Cuto frequency to be aected by the
keyboard velocity.

Cuto Velo Sens -100–+100
Use this parameter when changing
the cuto frequency to be applied as
a result of changes in playing velocity.
Specify a positive “+” value if you want
the cuto frequency to raise when you
play strongly, or a negative “-” value if you
want it to lower.
Cut KF Base Point 0–127
Species the reference key when using
Keyfollow to modify the cuto frequency.
If this is 60, the C4 key (middle C) is the
reference key.
FILTER ENVELOPE
Depth -63–+63
Species the depth of the Filter envelope.
Higher settings increase the change
produced by the Filter envelope.
Negative (-) value will invert the shape of
the envelope.
Fine Depth -63–+63
Finely adjusts the depth of the lter
envelope.
Velocity Curve FIXED, 1–7
Selects one of the following seven types
of curve by which keyboard playing
dynamics aect the depth of the lter
envelope.
If you don’t want keyboard playing
dynamics to aect the lter envelope
depth, specify “FIXED.”

Velocity Sens -100–+100
Specify this if you want keyboard playing
dynamics to aect the lter envelope
depth.
Specify a positive “+” value if you want the
lter envelope to apply more deeply as
you play more strongly, or a negative “-”
value if you want it to apply less deeply.
T1 Velocity Sens -100–+100
Specify this if you want keyboard playing
dynamics to aect Time 1 of the lter
envelope.
If you want Time 1 to be speeded up for
strongly played notes, set this parameter
to a positive “+” value. If you want it to
be slowed down, set this to a negative
“-” value.
Parameter Value Explanation
T4 Velocity Sens -100–+100
Specify this if you want key release
velocity to aect Time 4 of the lter
envelope.
If you want Time 4 to be speeded up for
quickly released notes, set this parameter
to a positive (+) value.
If you want it to be slowed down, set this
to a negative (-) value.
Time Keyfollow -100–+100
Specify this if you want the lter envelope
times (Time 2–Time 4) to vary depending
on the keyboard position you play.
Relative to the lter envelope times at
the C4 key (middle C), positive “+” values
shorten the times for notes played in the
region above C4, and negative “-” values
lengthen the times.
Higher values will produce greater
change.

Key
Time
LFO Trigger Switch OFF, ON
If this is “ON,” the lter envelope is
cyclically retriggered by LFO1.
* This is valid when the Envelope Mode
(p. 47) is “SUSTAIN.”
Time1 (Attack)
Time2
Time3 (Decay)
Time4 (Release)
0–1023
Specify the lter envelope times
(Time 1–Time 4).
Higher settings will lengthen the time
until the next cuto frequency level is
reached. (For example, Time 2 is the time
over which Level 1 will change to Level 2.)
* If ADSR Envelope Switch (p. 47) is
“ON,” the Time 2 has no eect.
