TVF VELOCITY

V-Cutoff (Cutoff Frequency Velocity Sensitivity)

Use this parameter when changing the cutoff frequency to be applied as a result of changes in playing velocity. If you want strongly played notes to raise the cutoff frequency, set this parameter to positive (+) settings. If you want strongly played notes to lower the cutoff frequency, use negative (-) settings.

To edit the overall Patch while preserving the relative differences in the Cutoff Frequency Velocity Sensitivity values set for each Tone, set the Velocity Sens parameter (PATCH/COMMON/PATCH MODIFY) (p. 72). However, this setting is shared by the V-Sens parameter (PATCH/TVA/TVA) (p. 90).

V-Curve (Cutoff Frequency Velocity Curve)

Selects one of the following seven curves that determine how keyboard playing dynamics (velocity) influence the cutoff frequency. Set this to FIXED when the Cutoff frequency is not to be changed according to the force with which the keys are pressed.

V-Resonance (Resonance Velocity Sensitivity)

This allows keyboard velocity to modify the amount of Resonance. If you want strongly played notes to have a greater Resonance effect, set this parameter to positive (+) settings. If you want strongly played notes to have less Resonance, use negative (-) settings.

TVF ENVELOPE

This is used for setting TVF envelope (how cutoff frequency changes over time).

Chapter 5. Creating Patches

Depth (TVF Envelope Depth)

Specifies the depth of the TVF envelope. Higher settings will cause the TVF envelope to produce greater change. Negative (-) settings will invert the shape of the envelope.

V-Sens (TVF Envelope Velocity Sensitivity)

Specifies how keyboard playing dynamics will affect the depth of the TVF envelope. Positive (+) settings will cause the TVF envelope to have a greater effect for strongly played notes, and negative (-) settings will cause the effect to be less.

V-Curve (TVF Envelope Velocity Curve)

Selects one of the following 7 curves that will determine how keyboard playing dynamics will affect the TVF envelope. Set this to FIXED when the amount of TVF Envelope applied is not to be changed according to the force with which the keys are pressed.

Time KF (TVF Envelope Time Keyfollow)

Use this parameter when you want the keyboard location of notes to affect times T2–T4 of the TVF envelope. Based on the TVF envelope times for the C4 key (center C), positive (+) settings will cause notes higher than C4 to have increasingly shorter times, and negative (-) settings will cause them to have increasingly longer times. Higher settings produce more change.

V-T1 (TVF Envelope Time 1 Velocity Sensitivity)

Use this parameter when you want velocity to affect T1 (Time 1) of the TVF envelope. If you want T1 time 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.
