[F3 (TVF)] - [F2 (TVF Env)])
These parameters determine the amount of filter enveloping
– changes to your original cutoff frequency setting that occur
over time – the effect of velocity on the TVF envelope, and
the basic characteristics of the TVF envelope itself.

Depth (TVF Envelope Depth)
Range: -63– +63
Determines the depth of the envelope when changing the
TVF cutoff frequency by the envelope. Higher settings will
cause the envelope to produce greater effect. With a setting
of zero, there will be no effect. With negative values, the
effect is reversed.
Time Keyfollow (Envelope Time Keyfollow)
Range: -63– +63
Changes the envelope time (from Time 1 to 4) relative to the
key follow point. Higher settings produce greater change.
Positive (+) settings will reduce the time when higher keys
are pressed. Negative (-) settings will extend time.
Time (TVF Envelope Time 1–4)
Range: 0–127
These settings determine the times over which the cutoff
frequency setting will change from one TVF envelope level
(L1–L4) to the next.
Level (TVF Envelope Level 0–3)
Range: 0–127
Each TVF envelope level value determines an amount of
change to be applied to the original cutoff frequency
setting.The Level during Note On is linked to L4.

Velo Sens
Amount (TVF Envelope Velocity Sensitivity)
Range: -63– +63
Use this parameter when you want keyboard playing
dynamics (velocity) to affect the depth of the TVF envelope.
For higher settings, there will be a greater difference between
softly and strongly played notes. Negative (-) values invert
the change.
Time1 (TVF Envelope Time 1 Velocity
Sensitivity)
Range: -63– +63
Use this parameter when you want keyboard playing
dynamics (velocity) to affect T1 (Time 1) of the TVF
envelope. For higher settings, there will be a greater
difference between softly and strongly played notes. With
positive (+) settings, greater keyboard velocity will reduce
the T1 setting. With negative (-) settings, greater keyboard
velocity will increase the T1 setting.
Time4 (TVF Envelope Time 4 Velocity
Sensitivity)
Range: -63– +63
Use this parameter when you want keyboard playing
dynamics (velocity) to affect T4 (Time 4) of the TVF
envelope. With higher settings, the T4 value will change
more significantly depending on whether you release the key
slowly or quickly. With positive (+) settings, greater
keyboard velocity will reduce the T4 setting. With negative (-
) settings, greater keyboard velocity will increase the T4
setting.
Pitch Depth (Envelope Pitch Depth)
Range: -63– +63
The TVF envelope can be used to change not only the cutoff
frequency, but also the pitch. Set the effect depth using this
parameter when modifying the pitch with the TVF envelope.
Higher settings will cause the envelope to produce greater
effect. With a setting of zero, there will be no effect. With
negative values, the effect is reversed.
