TVF Envelope
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.
fig.04-045.e
Depth (TVF Envelope Depth)
Range:
 -63– +63
Adjusts the amount of filter enveloping. Higher values will 
cause greater change. Negative (-) values invert the effect of 
the TVF envelope.
Time Keyfollow (TVF Envelope Time 
Keyfollow)
Range:
 -100– +100
Use this parameter when you want a note’s keyboard 
position to affect times T2–T4 of the TVF envelope. Higher 
settings change the times by a greater amount as you move 
away from Middle C (C4) — at Middle C, the original T1–T4 
settings are in effect. Positive (+) settings cause the times to 
shorten as you play above Middle C. Negative (-) settings 
will extend time.
Time1–4 (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.
Level1–4 (TVF Envelope Level 1–4)
Range:
 0–127
Each TVF envelope level value determines an amount of 
change to be applied to the original cutoff frequency setting.
Velo Sens (TVF Envelope Velocity 
Sensitivity)
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.
Velo Curve (TVF Envelope Velocity 
Curve)
Range:
 FIXED/1–7
This selects one of seven velocity curves that determine how 
velocity will affect the depth of the TVF Envelope. The 
selected curve is displayed graphically to the right of its 
value.
