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.

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)

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.

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.
