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.

 -63– +63

Adjusts the amount of filter enveloping. Higher values will 
cause greater change. Negative (-) settings invert the 
direction of the changes made by the Pitch Envelope.

 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.

 0–127

Each TVF envelope level value determines an amount of 
change to be applied to the original cutoff frequency setting.

 -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.

 -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.

 -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.

 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.

When set to “FIXED,” the TVF envelope depth remains 
unchanged, regardless of how hard or soft you play.

fig.06-017.e_70

The TVA (Time Variant Amplifier) controls volume changes 
to the Tone as well as its stereo positioning.

 0–127

Sets the volume of the Rhythm Tone. Use this parameter to 
adjust the volume balance between Rhythm Tones.

The overall volume of the Rhythm Set is set by the Rhythm 
Level (Rhythm Common page) setting, raising or lowering 
the Tone level settings of its individual Rhythm Tones by the 
selected amount. (p. 169)
