Filter Env (Filter Envelope)
These parameters specify the depth of the filter envelope (time-variant change in cutoff frequency), and specify the shape of the envelope itself.
Parameter Value Description
F-Env Depth
(Filter envelope
depth) -63– +63 Depth of the filter envelope
Increasing this value will produce a greater effect. Negative (-) values will invert the envelope.
F-Env V-Curve
(Filter envelope
velocity curve) FIX, 1–7 Curve by which keyboard playing dynamics will affect the filter envelope
If you select “FIX,” the filter envelope will remain constant regardless of your playing dynamics.
F-Env V-Sens
(Filter envelope
velocity sensitivity) -63– +63 Amount by which your pad playing dynamics will affect the filter envelope depth
Increasing this value will cause a correspondingly greater difference between softly played and
strongly played notes. Negative (-) values will invert the change.
F-Env T1 V-Sens
(Filter Envelope
Time 1 Velocity
Sensitivity) -63– +63 Amount by which your pad playing dynamics (velocity) will affect T1 (time) of the filter envelope
Increasing this value will cause a correspondingly greater difference between softly played and
strongly played notes. Negative (-) values will invert the change. Specify a positive (+) value if you
want to speed up the T1 time, or a negative (-) value to slow it down.
F-Env T4 V-Sens
(Filter Envelope
Time 4 Velocity
Sensitivity) -63– +63 Amount by which the speed at which you release the pad (key-off velocity) will affect T4 (time) of the
filter envelope
Increasing this value will cause a correspondingly greater difference between slowly released and
quickly released notes. Specify a positive (+) value if you want to speed up the T4 time, or a negative
(-) value to slow it down.
F-Env Time1–4
(Filter Envelope
Time 1–4) 0–127 Filter envelope times (T1–T4)
Higher settings of these values will lengthen the time over which the next cutoff frequency level of
the envelope is reached. (For example, T2 is the time over which the level changes from L1 to L2.)
* Realtime modify knob [A] adjusts Time 1, knob [D] adjusts Time 3, and knob [R] adjusts Time 4.
F-Env Level0–4
(Filter Envelope
Level 0–4) 0–127 Filter envelope levels (L1–L3)
Specifies the change in cutoff frequency at each point, relative to the reference level.
* Realtime modify knob [S] adjusts Level 3.
